also known as Ethernet-based control,named after a popular local area network(LAN) topology—although any type ofnetwork using TCP/IP may be used. TheMatrix 12800 ships with an intuitive Webinterface for these common operations:I/O switching, global presets, and onlinediagnostics and monitoring. Installationand configuration of the Matrix 12800for a network can be accomplished inthree easy steps:

1. Assign the Matrix 12800 a static IPaddress.

2. Connect the Matrix 12800 to thenetwork using its built-in RJ-45 port.

3. Use your favorite Internet browserto administer the Matrix 12800.

In addition, you can send RS-232commands using Extron’s SimpleInstruction Set (SIS™) through custom-made Web pages created in off-the-shelfprograms, such as MacromediaDreamweaver or Microsoft FrontPage.(See Image 2 for an example of acustomized graphical interface.)

limited control of the matrix, so inadvertentchanges or modifications are prevented.

For secure installations, such asgovernment applications, that do not allowInternet access, online monitoring stillprovides a proactive advantage. Using anexisting secure infrastructure set up by thecustomer’s information systemsdepartment, you can receive emailnotification of failures and repairs withoutcompromising the security of the A/Vsystem and facility. With this existing one-way email communication method, statusnotification comes out of the Matrix 12800,but information and functional changes arenot sent to the Matrix 12800.

Another benefit for secure installationsthat prohibit Internet access is access withinthe LAN or wide area network (WAN), stillprotected by the firewall. Internal accessusing browser-based control makes localcontrol, maintenance, and service easier tomanage and accomplish.

Plus—traditional RS-232 control is point-to-point control, while browser-basedcontrol is multi-point. Using browser-basedcontrol via TCP/IP, multiple users canmonitor and/or make adjustments at thesame time.

Matrix 12800The Matrix 12800 Series has a video

bandwidth of 375 MHz (-3dB) when fullyloaded, and provides modular switching ofRGBHV, RGBS, RsGsBs, RGsB, componentvideo/HDTV, S-video, composite video,and/or two channel stereo audio(balanced/unbalanced). Every wideband orsync model provides for a minimum 32 x 16configuration, and every audio modelprovides for a minimum 16 x 16configuration. Each model includes theflexibility to upgrade up to 128 x 128.

Self-DiagnosticsWith its innovative features, including

online remote control and monitoring,

the Matrix 12800 is an excellent choicefor off-site or unmanned A/V systems,especially sensitive, 24 hours a day, 7days a week environments.

Advanced computer aided diagnosticsprovides 24-hour self-diagnostics of I/Oboards, power supplies, controllers,cooling fans, and general functions of thematrix. Confirmation of input sources isperformed by Extron’s exclusive DSVPtechnology, which scans all RGBS orRGBHV inputs for active sync signals.DSVP enables remote monitoring of RGBSor RGBHV source signal activity throughRS-232 by providing the horizontal andvertical frequencies of each input.

Mission Critical, Hot-SwappableComponents and Redundancy

The Matrix 12800 offers theconvenience of hot-swappable I/Oboards, power supplies, and cooling fans.(See Image 3). Hot-swappablecomponents allow the user to replace anypart at any time—no need to powerdown the matrix during fieldmaintenance. This is especially useful for crucial applications that require continuous operation of the Matrix 12800. The user may expand thematrix or swap out components withoutdisrupting the matrix’s functions.

For mission-critical applications, theMatrix 12800 offers dual, fullyredundant, and hot swappable powersupplies and cooling fans. The primarypower supply system is configured tosupport automatic fail-over to a hot sparepower supply. This means zero downtimefor the system and no loss of functionalityshould a power supply fail. Also,installation and service are easy becausethere is no need for tools to remove eachpower supply and each is accessiblethrough the front of the matrix switcher.Four cooling fans are provided forventilation and heat management. Fansand filters are easily accessible throughthe front panel for maintenance andreplacement. Sensors notify the user ofany failures—through visual cues, RS-232/422 communications ormessages through the browser-basedcontrol system.

PresetsUsing a feature called “rooming,”

each Matrix 12800 can be programmedto assign multiple outputs to specific“rooms,” allowing them to have theirown grouped presets. The Matrix 12800also offers global presets that can besaved or recalled to define I/Oconfigurations of specific inputs to anyspecific combination of outputs or to all outputs.

ControlControlling any system is easy with the

Matrix 12800. In addition to browser-based control, RS-232/422 control isavailable via a third-party control systemor Extron’s Windows®-based controlsoftware for a PC. The optional intuitiveFPC 2000 Front Panel Controller has alarge LCD window that allows directaccess and total control over the Matrix12800 switching functions. Additionalremote control convenience may beprovided by the MKP 1000 remotekeypads and/or the MCP 1000 remotecontrol panels.

Extron’s 2001 Oasis Bash, held on June13th during InfoComm in Las Vegas, wasthe place to be for the 7th annual Battle ofthe Bands. Display manufacturers traded intheir business attire for guitars, and went onto burn the house down with an evening ofhigh-energy rock and blues. Staged at theMGM Grand Adventures Theme Park, theBattle of the Bands is not exactly acompetition—it’s simply an outlet to getloose and kick out the jams. In fact, an air ofrespect and admiration is pervasivethroughout the proceedings.

“The best part about the three bands isthat we all play different styles of music,”said Cathy Hussar, Ceiling Mount singer andManager of Marketing Services for NEC.Drummer Wayne Bickley, DevelopmentManager of Entertainment and LeisureDisplay Products added: “I don't think any ofus really gauge ‘how good we or they are.’We do this to relieve the stress of the show.”

As partygoers explored the makeshiftamusement park, the musicians prepared fortheir moment in the sun. Just before 7:00,NEC’s Maximum Bandwidth & The CeilingMounts mounted the stage and the Battle ofthe Bands was underway.

NEC’s Maximum Bandwidth & TheCeiling Mounts

“We’re honored to open the 7th annualBattle of the Bands,” announced singerMark Julian, Regional Sales Manager forNEC. Maximum Bandwidth & the CeilingMounts wasted no time as they plowed rightinto Lynyrd Skynyrd’s ode to the south,“Sweet Home Alabama.” Julian led the

chorus and worked the crowd while IraStanley, CFO for MCSI sitting in for LloydHastings, traded guitar licks with RichMcPherson, Product Engineer for NEC.Julian then invited Able Design andFabrication’s Lou Mannick up to sing andblow some harp on “Mustang Sally.”

Shifting gears, the group paid a tribute tothe 80s with a searing version of theRomantics’ “What I Like About You.” Fromthere, they went into the Jimi Hendrixclassic, “Little Wing.” Stanley sang, as wellas burned up the fret board during thisnumber. Things lightened up with GeorgiaSatellites’ “Keep Your Hands To Yourself”before the set was closed with the RollingStones’ “Jumpin’ Jack Flash.” Julian andStanley swapped verses while the CeilingMounts bounced and boogied. “We areNEC and we’ll see you next year,” Julianshouted as the band left the stage.

The Christie Blues BandThe Christie Blues Band hit the stage with

a far more subdued, traditional blues set.Warming up for their own party the

They followed with WilsonPickett’s “In The Midnight Hour”—infusinga more bare bones approach strewn withauthentic bluesy intonations.

Guitarist Paul Comella, Control RoomField Specialist for Christie, played an intro,and the band fell into Robert Johnson’sseminal “Sweet Home Chicago.” Sung bySpeer, the band slipped into a jam thatdefies description. A sideshow mime andstilt-walker shimmied about as Weatherssang and the crowd came to life.

lethal combination of folk, blues, androck. They opened with Bob Dylan’s “I'llBe Your Baby,” a slow country ditty, andflowed right into the Eagles’ “Peaceful,Easy Feeling.” Lee Wolloff, ProductManager of Barco Projection Products,sang and strummed his acoustic whilerhythm guitarist Jerry Dixon, ProjectionProducts National Sales Manager forBarco, tried his hand as a back-up singer.During Bob Seger’s “Old Time Rock n’Roll,” Pete Putnam, a noted A/Vjournalist, played a captivating piano solowhile guitarist Bruce Allers, National SalesEngineer for Barco Rental Staging, laiddown a smokin’ harmonica solo. OnceDixon segued into Creedence ClearwaterRevival’s “Green River,” even Extron’spresident, Andrew Edwards, danced awayunder the moonlit skies.

The band took a stab at the DoobieBrothers’ “Long Train Runnin’,” and toreinto Santana’s Grammy-winning hit“Smooth” for their grand finale. Takinglead vocals, Allard executed an excellentguitar solo while Wolloff injected a littlesalsa flavoring with a gourd shaker. Dixonsaid the Barco Band is already preparingfor the next Battle of the Bands. “We'regoing to field a 100-piece kazoo band,doing several Dire Straits tunes.”

And We Bid You GoodnightNormally, the All-Star Band, a fourth

band comprising of some of the playersfrom the previous three, would haveclosed out the festivities. Unfortunately,time and scheduling restraints hamperedthe idea.

Regardless, Extron President Edwardspraised the event as “the greatest showon earth.” As Haute Chile, an eight-piecedance and show band, played into the night, one could only speculate what surprises we can expect to see and hear during the next Battle of the Bands.

One of the first lessons one

learns about marketing is the

name of the game is

responding to customer

needs. Simple enough, but

sometimes simple requests

can be very difficult to

implement. Extron’s product

color change is a perfect example

of this. As many of you know, Extron

products have had a characteristic light grey

color that made them distinctive and easy to

identify. This color was also chosen due to

its ability to hide smudge marks and dirt. As

proud of the color as we were, over the years

we had received a low, but constant stream

of requests to make the grey color darker

because it stood out too much when

installed in an equipment rack full of black

products, which were becomming more and

more common.

Each time such requests would come in

we would dutifully log them and periodically

raise the issue internally. Of course there

were many opinions of exactly what it

should change to (i.e. black, dark grey-1,

dark grey-2, etc.) but all mentioned that

most complimentary products were black or

dark shades these days. Well, from our

perspective, we were quite proud that our

products were identifiable and visible in a

rack. In addition, the color was very well

known and part of the Extron branding that

has been built up over the years. These are

important issues for a manufacturer and one

does not take such changes lightly.

Much internal wrangling and numerous

discussions took place about how difficult it

would be to choose a new color worthy of

replacing our old standard and how to

implement the change over on hundreds of

products, documentation, and existing

inventory. However, as they say, the

customer is always right. We realized that

we must rely on Extron’s basic principle of

listening to our customers and giving them

what they need—and we made the change.

Our justification came by realizing that our

objective in creating new products was to

improve the solutions available to our dealers

and consultants. This extends beyond

improving the performance, features,

usability and system design aspects and goes

all the way to the aesthetics of the products

to optimize their look in systems.

The response to the new Extron grey has

been very positive. As difficult as it is for

organizations to change, it is important to

maintain our market and customer focus.

This has applicability for any organization.

Do not assume that what the customer told

you they wanted before is still what they

want today. Times change and needs

change. Part of staying competitive is the

ability to adapt to those changes and strive

to continually meet customer needs.

From the surface, Extron’s recent color change for all of our products

would seem to be a simple matter of a few focus groups to decide

just which shade of grey to pick, right? Maybe so, but often simple

issues become complex actions. The product color change created some

enormous internal logistical issues to work through and in the end

proved to be a refreshing exercise in customer focus.

Improving the Look of A/V SystemsSome Thoughts About Customer Input

by Lee Dodson, Vice President of Marketing

M A R K E T I N G M A T T E R S

NewExtronGrey

At Extron, we rely on these dealerassessments to determine which products areneeded in the A/V industry. We respond to ourcustomers’ needs, as each installation isunique and may not fit into a standard mold.And, while some small system requirementsare cut and dried, Extron provides a widerange of solutions to get all systems working100% of the time, including: a broad productline, dealer education and training, E-Demos,application brochures/stories, product guides,and personalized videoconferencing sessions.

In turn, dealers should rely on theircustomers’ good judgment. Today’sconsumers are more technology savvy than inthe past. While they may not understand allof the intricacies of an A/V system, they dounderstand the value of a system that isreliable, and how planning for futureupgrades now can save them money, time,and aggravation later. Time spent educatingthe end-user on all possible solutions andhelping them choose the best one for theirspecific needs and budget, is a sound businessinvestment. Clients will appreciate it when thejob is completed, and will also remember itwhen they need help with their next A/V project.

September/October 2001 ExtroNews 12.4 7

With advances in technology and the continuous introduction of

new and different signals, designing and integrating A/V systems

is becoming increasingly complex. In contrast, more and more end-users

desire an economical system that is easy to use, maintain, and upgrade.

What is the solution?

Knowledge is a Valuable Tool

T H E E X T R O N H O T L I N E

by Jeff Gibson, Vice President of Sales

The answer is knowledge and experience.A dealer’s expertise is crucial in engineeringan A/V system that meets their customers’current needs, yet allows for futureexpandability. It is no small task to integratea complicated system, which may includevariables such as videoconferencing andEthernet connections, into one userinterface that is simple to operate from anend-user’s perspective. Not to mentiondoing so within a client’s budget. However,by learning from past installations andutilizing all of the tools and informationavailable, it is possible.

An experienced dealer will start byanalyzing their customers’ current andfuture needs, taking into consideration allpossible applications, the various types ofusers, and what system features arepriorities. Next, they will take into accountthe design of the room, what new andexisting A/V products will be used within thesystem, and the client’s budget. Finally,when all this information is collected andreviewed, a decision can be made as towhich (Extron) products are needed toachieve dependable system integration withsuperior quality output.

These same $60networks are identical to the one atwork…just fewer ports and less hardware.This is Ethernet networking and it isbecoming commonplace as the most popularnetworking protocol for offices and homes.Networks, whether in your office or home,are islands of device intercommunicationwithin the confines of that specific network.

When we talk about wiring a facility withCAT 5 wire, we are setting up theconnections for a 100Base-T Ethernetnetwork. The installed wiring, connections,hubs, etc. are the physical layer betweenhardware components. The Ethernetinterface and protocol are the data link layer,which actually handles communicationsbetween devices. So, what’s all this “layer”stuff about anyway?

In the 60’s and 70’s when networking gotits start, there were, and still are, manynetworking methods or protocols. A protocolis simply an agreed-upon method for

microwave oven notifying me via a network touch-screen terminal that

my popcorn is ready while I’m watching the Titanic sink again; as long

as I’m not interrupted when Leonardo DiCaprio sketches the heroine’s

portrait. While some of these notions seem like solutions looking for a

take advantage of networking technology. Going one step further,

interacting with intelligent products through the Internet opens a new

communicating data between two devices.The International Standards Organization(ISO) developed a model to be used fordesigning network protocols. Their OpenSystems Interconnect, OSI, presents a high-level approach for describing networkcommunications all the way from the wireconnecting the network up to the softwareapplications we use to communicate. Theseven-layer model is shown in Figure 1. Eventhough each layer cannot stand alone anddepends on the others around it, the ISOmodel provides a means for designingnetworking protocols having similarcharacteristics that make their usefulnessgreater on a worldwide basis. The Internetprotocol fits nicely within this layeredstructure.

But, let’s get back to the Ethernetdiscussion. Hardware devices that plugdirectly to computer-based networks aretypically Ethernet devices. Ethernet operatesunder its own procedures for managing thetransfer of data between devices and hasbecome the de facto standard for LANs andWANs. Refer to the sidebar on the EthernetProtocol for more details. Connecting mytwo home computers together underWindows‚ was essentially automatic. So,most computers talk on the same networkusing Ethernet protocol. All is well, but whatFigure 1. 7-Layer ISO Model

happens if you want to connect your lonenetwork to the rest of the world?

This was the problem DARPA (DefenseAdvance Research Project Agency) decidedto solve in the 60’s. A method was needed tocross-connect and share super-computerfacilities among all involved universities. Theresult was the ARPANET in 1969. TheARPANET grew to be what we call theInternet today. Connecting a local networkto the Internet requires a language protocolunderstood by other types of LANs andservers. This is where TCP/IP (transmissioncontrol protocol/internet protocol) comes in.TCP/IP is the “language” of the Internet andcomprises a whole suite of protocols thatfacilitate transmission of data throughout theWorld Wide Web. The TCP/IP protocolsoperate between the data link layer (localEthernet) and the applications layers (webbrowsers and other applications). Figure 2shows the relationships of these layers in theISO model. TCP/IP could be replaced withother networking protocols, but since we aretalking about the Internet, we will talk aboutTCP/IP.

When we visit a web site or go to get ouremail, we interact with another file server(computer) somewhere. The server deliversour mail or, if we go to purchase a product orservice online, we interact with the features(buttons and selections) on a page ofinformation. Decisions are made based onthe selections we make within the web page.Information is made available, we provideinformation on forms, and the pages andfeatures change as we interact.

Now, imagine that any product on themarket had built within it a small computersystem that could provide information aboutitself in the form of an HTML web page. Ifthis product is connected to a local networkwith Internet access or has direct access to

the Internet, we could call up its name(which translates to an IP address) from anyInternet-connected computer in the world.The product’s internal computer would serveup its internal web page. Functions on theweb page could be as simple or as interactiveas economics allow.

Once connected to the product via theInternet, we can interact in a significant way.We could accomplish many things, such as:

• Interrogate the product for its status• Review its length of service and version• Interact with its controls• Operate it remotely• Perform diagnostics or updates

Taking this one step further, entire systemscan be monitored and operated. There arenearly limitless possibilities available to us viaany Internet connection worldwide. Homeand business automation will excel throughthis capability.

Ethernet Protocol

Developed in 1972 by Dr. Robert M. Metcalfeat Xerox PARC, this protocol and physicalmedium became the common method tocarry data to all systems. From its verybeginning, Ethernet specifications and rightshave been available to anyone. Its mostcommon implementation is in 10Base-T (10Mbps baseband communications overtwisted pair) local area networks and, morerecently, in 100Base-T (100 Mbps, FastEthernet) systems utilizing twisted pair cable.Today, the protocol, adopted by the IEEE, iswidely known as IEEE 802.3. The protocolconsists of the physical medium (wire orfiber), access control rules that allow sharedaccess to the channel, and the data frame.

All computers on an Ethernet network areindependent and have equal access.Computers must “listen”for the completion ofa data frame transmission and contendequally for access to the data channel. TheNIC, or network interface card, in a computercontains the medium access control (MAC)mechanism. Ethernet is characterized by itsown data collision arbitration protocol calledCarrier Sense Multiple Access with CollisionDetection, or CSMA/CD.

The Ethernet frame carries data in a variablelength field of up to 1,500 bytes plus addressfields and error checking fields. The first twofields contain 48-bit MAC addresses calledthe source and destination addresses. Theaddress for each NIC card or other Ethernet-compatible product is unique.The first 24 bitsdefine the manufacturer of the device andthe remaining 24 bits represent a numericaladdress programmed by the manufacturer.All Ethernet devices on a network listen todata frames and respond if there is a matchwith the destination address.

LANs built on Ethernet use the starconfiguration whereby all users areconnected directly to the hub or router.Hubs,switches and routers are connected in asimilar fashion; thus defining what is knownas a system “tree.”

The basic Ethernet frame:

Figure 2. The Network Layers or “The Stack”

T E C H N I C A L L Y S P E A K I N G . . .

255.010.100.001 for example. Each numbergroup subdivides the address for the purposeof identifying a specific network and itsnode, or user.

Historically, addresses were classified intothree groups, or classes, called A, B, and C.Large networks receive a Class A address.Medium size networks receive Class B andsmall networks are considered Class C.Today, most networks fall in the Class Cgroup and, as the Internet growsexponentially, there is concern that thecurrent system will run out of address spacewithin 10 years. To combat this problem inthe interim, most networks use a “subnetmask.” This mask is an address manipulatedby the local IP router for a network. This localrouter keeps track of who is connected tothe network and replaces parts, or all, of theIP address with a more specific address thatallows routing to the final location. Thismethod saves on IP address assignments.

As you can see in Figure 3, there are manycomponents to the IP header. Thisinformation is in addition to the localEthernet header and is further “wrapped” bythe TCP header with each header servicingthat protocol concerned with its specific

function. A full discussion of all headerinformation is beyond the scope of thisarticle, but the interested readers may find allthe details by viewing or downloading thefull specification at: http://www.cis.ohio-state.edu/Services/rfc/index.html. TCP/IPprotocols are openly supported by RequestFor Comment documents; commonly calledRFCs. RFC 0791 describes IP completely.

In particular though, there are a fewthings of interest you should know about. IPrequires that a version be given. While thisalways has a 4 loaded here for the currentversion of IP, there are plans for moving toIPv6 (version 6; don’t worry, there is noversion 5) to expand address space andfeatures. There is a time to live field thatcontains a number, which is decrementedeach time the message is handed off toanother router. This ensures that datagramswill not circulate through the Internetindefinitely. The next protocol for handoff,TCP, must be designated in the protocol fieldas well since IP can work with other Internetprotocols for datagram routing. Aninteresting feature is the options field.Although the option field must be supportedin datagrams, it may or may not appearwithin a given datagram. Key optionshandled by IP are datagram security, methodof routing, and an Internet timestamp. Whenoptions are invoked, the generated data isadded into the datagram’s string of databytes.

Products having IP capability typicallymake use of the timestamp. An IP capableproduct will have a real-time clock providingtime information. The timestamp is a right-justified 32-bit number representing, inmilliseconds, the time since midnightUniversal Time (Coordinated). UT succeedsGreenwich Mean Time (GMT) as the world’stime standard. For more information on GMTor UT, refer to The Concept of Time sidebaror go to http://www.greenwichmeantime.com.There are multiple options for the timestamp,

How it worksFrom the ISO model, we see that TCP/IP is

a set of protocols piled above the Ethernetprotocol. The first step in Internetconnectivity is the Internet Protocol (IP). SinceIP lies at the network layer, it utilizes anaddress to identify the node (user orappliance) on a network. The IP address isthe essential element that supports therouting of a datagram (term for an Internetmessage) through the Internet. IP is onlyconcerned with routing the message, not thecontents of the message. Figure 3 diagramsthe actual IP header contents. The localnetwork’s IP router typically assigns IPaddresses dynamically.

So, what is the significance of an address?Like the Ethernet protocol, there is no onecomputer on the Internet considered amaster controller. All systems operateequally. For an Internet datagram to find itsway through the net to a specific destination,there must be some significance to the IPaddress. Currently all IP addresses are 32 bitslong, or four bytes, or four octets. Theaddress is the number grouping you regularlysee displayed on the screen when surfing thenet. Since a byte is equivalent to 256 bits, theaddress is displayed in decimal form as

Figure 3. IP Header

T E C H N I C A L L Y S P E A K I N G . . .

but essentially, it records the official time andIP address for the accessed network nodeand all router/gateway hops involved in thetransmission. The timestamp can providevery useful information about timing androutes.

Climbing the StackInternet Protocol makes it possible to

connect a product or a user to any otherproduct or user in the world via the Internet.So far, this article describes the basicconcepts starting with the physicalconnection, the Ethernet protocol (data linklayer), and IP (network layer). There are stillthree to four layers in the stack to climb.

TCP’s header and control protocol wrap IP.TCP is on the transport layer and isresponsible for breaking up a message intodigestible datagrams capable of beinghandled by all routers and protocolsencountered during the journey from thesource to the destination. Some systems limitthe datagram size, so messages may becomefragmented enroute. TCP keeps track ofdatagrams and reassembles them at thedestination. You can see that TCP and IPwork hand-in-hand…IP finding the addressand route while TCP takes care of messagefragmentation.

TCP is also used on the next layer up thestack… the session layer. Once a connectionis made between two network nodes, TCPmaintains the open session ofcommunication between nodes for theduration of time required to transport alldatagrams to the destination. TCP opens thesession and closes it after the datagrams aredelivered and reassembled.

After the message is recreated from oneor more datagrams, TCP hands off themessage to the presentation layer. At thislayer we typically encounter HTTP (hypertexttransmission protocol) interpretation andemail handling (POP3 and SMTP). HTTP

translates data from web page interactions…inputting data, selecting icons, pushingbuttons, etc. It is at this level where IP-capable products can send or receivemeaningful data that can be interpreted intofunctional actions and operations.

As humans, we interact on the top layer ofthe stack; the application layer. This is whereour web browser takes the http informationand presents it in a graphical or text formthat we can relate to. Our interactiondepends on seeing an action that we are ableto interpret into something meaningful.However, for machines, interpretation takesplace on the presentation level. Theapplication layer must be supported on theIP-capable product if we wish to interact likewe normally do with a computer system.Otherwise, IP products need only operate atthe presentation layer and give us feedbackin the form of simple operational indicators,like indicator lights or text displays.

The Future?The IP address landscape is crowded. The

Internet has grown and is growing beyondproportions anyone could have imagined. Formost of us, more bandwidth is our dream.For the various caretakers of this myriad ofnetworks, a key problem is address space. Bewatchful of more activity andannouncements about Internet Protocolversion 6, IPv6, coming to a network nearyou. IPv6 increased address length from 32bits to 128 bits. We will be swimming in IP-capable toasters before address spacebecomes limited under IPv6. This new versionis in comment and trial now. Expect thetransition to be gradual, and perhapstransparent. The Version 6 header structure issignificantly different than version 4. So,there will be some time required before allsystems can transition between the twoformats. In the meantime, think about the IP-based product possibilities. Someday, evenyour trashcan may tell you when it’s time totake out the garbage.

The Concept of Time

Time, as theory tells us, is a relativething…relative to the events around us,like the sun moving across the sky. Beforethe days of the industrial revolution,tracking time was a local activity. A fullrotation of the earth (360˚) in 24 hoursmeans that the sun is moving relative tous 15˚ per hour. We put a stick in theground and determine noonday easily bywatching the shadow. Then, for ourlocality, we know the time of day. But,travel a few miles away and it’s notmidday. Commerce via ships at sea andtrains on land dictated that some form ofuniversal time measurement andcoordination was needed worldwide.

England took a serious role in the timeproblem during the days of its expandingempire. So much so that in the 17thcentury the Royal Observatory inGreenwich, England became the host oftwo really important world references:the point of 0˚ longitude and theuniversal time standard called“Greenwich Mean Time,” or GMT. The USadopted GMT in 1884 when telegraphlines began transmitting time signals tomajor cities. With GMT as the marker, theearth is then divided up into 24 timezones all referenced to GMT. Travelingeast from Greenwich, the first zone isGMT+1, then GMT+2, etc. Traveling westfrom Greenwich, time zones are labeledGMT-1, GMT-2, etc.This method proceedsin each direction for twelve time zonesuntil the International Date Line isencountered directly oppositeGreenwich, England. This reference isreferred to as “mean time” because it isthe average of the earth’s rotation. Earthrotation varies from day to day and hasinherent error in terms of our timekeeping. Leap seconds must be addedperiodically to make up for the differencein earth position.

Today, Universal Time Coordinated (UTC)replaces GMT as the world standard andis based on the cesium atomic clock.Anyone needing something to say at aparty might want to memorize the 1967SI official definition of one second: “theduration of 9,192,631,770 periods of theradiation corresponding to the transitionbetween two hyperfine levels of theground state of the cesium-133 atom.” Inany case, utilizing GMT, or UTC, establishesa standard time reference and your general location on earth.

Courtroom activities require accuratedepiction and reproduction of audio and videodata; as a result, courthouses are selectivelyintegrating A/V systems into their courtrooms.Some benefits of this transition include thefollowing: evidence quickly viewed by everyonevia monitors; remote testimony enabled byvideoconferencing; Internet and media feedsfor broadcast; and computer-generateddemonstrations.

Courtroom 23 was inspired by Courtroom21, a joint collaboration between the College ofWilliam & Mary and the National Center forState Courts. Located at the College of William& Mary, Courtroom 21 is a well-known,continually evolving demonstration of A/Vtechnology integrated into a courtroom.Courtroom 23, part of the Ninth Judicial CircuitCourt of Florida, is located on the 23rd floor ofthe Orange County Courthouse in Orlando, FL.Applied Legal Technologies designed the A/Vsystem, while DOAR Communications and theA/V engineers at the Ninth Judicial Courtinstalled the A/V system.

DOAR Communications’ David Goldenberg,Vice President, Sales, remarked, “Courtroom 23is perhaps the most significant state courtroomtechnology project to date. The courtroomprovides state of the art technology in acompletely integrated format, which works in avery sophisticated way in the architecturallybeautiful room. DOAR is proud to be theprimary provider of evidence displaytechnologies, videoconferencing, transcriptanalysis, and information management for thislandmark project.”

The System 7SC incorporates Extron’sexclusive advanced film mode processing with3:2 pulldown detection for NTSC and 2:2 filmdetection for PAL. This helps maximize imagedetail and sharpness for NTSC and PALmaterials that originated from film. Alsoprovided are Extron’s exclusive Dynamic MotionInterpolation (DMI™) and Accu-RATE FrameLock (AFL™) scaling technologies. DMI is anadvanced motion prediction and compensationmethod used to deliver the best aspects of stilland motion algorithms. This process results in asuperior level of image enhancement capabilitywith no loss of image fidelity. AFL eliminatescommon frame rate conversion difficultiesexperienced during scaled motion video.

Courtroom 23’s current TP A/V transceiverswill be replaced by Extron’s TP transceivers.“Right now the technical support for thosetransceivers is located overseas and isn’t thataccessible, so we hope to use Extron’s TPtransceivers instead—which also come withExtron’s high level of support. We’re looking tomake that changeover in the upcomingmonths,” remarked Gruen.

Extron offers a versatile class of TPtransmitters and receivers that enable long-distance transmission of RGB video, componentvideo, S-video, composite video, and stereoaudio using Category 5, 5e, or 6 UTP cable.Extron TP solutions are designed to be used theway A/V system designers and installers buildsystems—offering the compact size,connectorization, remote control capability, andmounting configurations needed forarchitectural integration, plus the level andpeaking control needed for high performance.

Feedback regarding Courtroom 23’s A/Vsystem switching has been favorable. Gruenconcluded, “The system works fine and isdependable. As technologies have evolved,we’ve changed out other components toexpand the A/V capabilities. But we’re keepingExtron’s system switcher because it’s reallyflexible. And we’re keeping an eye on othertechnologies to see what can be used a fewyears down the line to keep Courtroom 23 onthe cutting edge in A/V technology.”

The SW 6 VGA Audio switches computer videoand audio inputs from two plaintiff computers,two defense computers, a podium computer,and the judge’s computer. (See system diagramon page 12.) The SW 6 VGA Audio’s output, a document camera, a VCR, and avideoconferencing system feed an ExtronSystem 4LDxi switcher with built-in line doubler.

Martin Gruen, President of Applied LegalTechnologies and design consultant forCourtroom 23, elaborated, “We are using theSW 6 VGA Audio to increase the number ofinputs for the system switcher. The SW 6 is aninexpensive and straightforward solution.” TheSW 6 VGA Audio is a six input, one output,active switcher that switches six computer videoand audio sources on 15-pin HD and 3.5 mmcaptive screw connectors. It provides a choice ofauto-switching and normal switching modes;auto-switching allows any input of the switcherto be selected automatically when the switcherdetects a sync signal.

“We chose the System 4LDxi because it is aswitcher with a line doubler. It’s ideal forcourthouses—simple-to-operate, effective,

stable. Plus it works with composite, S-video,and RGB video sources,” Gruen continued. TheSystem 4LDxi is a four input, one outputswitcher with built-in line doubler and universalprojector control. It provides switching ofbalanced and unbalanced stereo audio andoffers audio breakaway. Audio breakawayenables the audio signal to be separated fromthe video signal to switch either the video onlyor the audio only.

The output from the System 4LDxi is sent tothe video marker for annotation. Theannotated output then goes to a one input, sixoutput, VGA distribution amplifier for routingto various destinations. One output is scanconverted down to NTSC video for distributionto a twisted pair (TP) A/V transceiver and anautomatic, line-level, A-B switcher. The UTP A/Vtransceiver routes NTSC video over unshieldedtwisted pair (UTP) cable to a video printer. (UTPcabling takes up less room in conduit andminimizes floor box size requirements for cableconnections.) The A-B switcher connects to adistribution amplifier, which routes the NTSCvideo signal to a second TP A/V transceiver forUTP routing, the Internet, and a media feed forpress cameras. The second TP A/V transceiverroutes its signal to the System 4LDxi for routingof annotated images.

Other destinations of the VGA distributionamplifier—which distributes the System 4LDxi’sannotated output—include a TP transmitter forrouting to a witness monitor; a two input, twooutput VGA switcher; and a TP transmissionchassis. The switcher sends signals to anRGBHV distribution amplifier for distribution tofour gallery plasma monitors. The switcher’sother output goes to the TP transmissionchassis, which is tied to a second TPtransmission chassis. The first chassis distributesA/V over UTP cable for distribution to the clerkand judge plasma monitors, as well as twodaisy-chained distribution amplifiers, whichfeed ten jury LCD monitors. The second chassisfeeds four attorney plasma monitors.

Future UpgradesThe System 4LDxi will soon be upgraded to

the System 7SC. Gruen commented, “TheSystem 7SC has even more capabilities,primarily its scaling abilities.” The System 7SC isa seven input, dual output, multi-formatswitcher with built-in video scaler and universalprojector and room control.

Ten LCD monitors are installed in the jury box.

The ISM series is designed forinstallations that require matrix switching andtwo individually scaled outputs. Because theISM Series provides flexibility in selectingoutput resolution to two different displays, itis ideal for dual-display videoconferencingand presentation environments such asboardrooms, conference rooms, classrooms,courtrooms, churches, and auditoriums.

There are two matrix switchers/scalers inthis series: the ISM 182 and the ISM 482.Both offer comparable features: eight videoinputs configurable for RGBHV, RGBS, RGsB,component video, S-video, or compositevideo on female BNCs and two highresolution RGB outputs for female BNCsand/or female 15-pin HD connectors. Stereoaudio (balanced/unbalanced) comes in oneight, 3.5 mm captive screw connectors andis output (balanced/unbalanced) on two, 3.5mm captive screw connectors. In addition tothe listed video formats, the ISM 482 can alsoaccept HDTV. The other difference betweenthe two models is in the scaled output rateseach supports. The ISM 182 can output 17different rates up to 1024 x 768 while theISM 482 supports 33 different output rates,up to 1365 x 1024 and including 480p, 720p,1080p, and 1080i.

Using digital processing, the Extron DVS406 can overlay text and/or graphics ontovideo. Hook up the computer and videocamera to the DVS 406. Then bring up thename and logo on a computer, and select thekeying feature. The video is then displayedwith the text and/or graphics keyed in (see Figure 1).

The DVS 406 is a resolution-enhancingvideo scaler with an innovative feature set. Itconverts NTSC, PAL, or SECAM video intohigh-resolution RGB video. It is an excellentchoice for a variety of A/V environments:hotel meeting rooms, corporate boardroomsand conference rooms, or churches.

Another staging application would be apanel presentation. The A/V system usesseveral cameras, each focused on a differentperson. Keying would be an excellent featureto use, so when a particular person isspeaking and on-screen, the audience caneasily identify that individual.

There is another feature useful for rentaland staging applications. The DVS 406provides seamless switching and effectsto enhance the professionalism and style oflive multimedia events and presentations.Seamless switching between RGB input #1and any video input is accomplished bylocking the scaled output rate to thehorizontal and vertical frequencies of input#1. There is a choice of a seamless cut or avariable dissolve. The user-adjustableduration of the dissolve varies from 0.2 to 1second. The DVS 406 also provides a cut orfade to black using RGB delay for switchingbetween two RGB inputs or between two video inputs.

Scaling TechnologiesThe DVS 406 combines input flexibility

and seamless switching with superior imagequality enhanced by Extron’s patent-pendingscaling technologies: Dynamic MotionInterpolation (DMI™), 3:2 and 2:2 pulldowndetection with True-Rate Film Recovery™,and Accu-RATE Frame Lock (AFL™).

DMI technology is an advanced motiondetection and compensation method used todeliver the best aspects of still and motionalgorithms. This process results in a superiorlevel of image enhancement capability withno loss of image fidelity.

problem by locking the output frame rate tothe input frame rate.

Input and Scaled Output FlexibilityInput flexibility is essential for today’s top-

notch A/V applications—and the DVS 406offers an optional Serial Digital Interface (SDI)input.

There are four models available: DVS 406,DVS 406 A, DVS 406 D, and DVS 406 AD.Using BNCs, each model supports thefollowing video formats on five inputs: 1)one RGB pass-through or HDTV to RGBconverter; 2) one RGB pass-through orcomponent video (interlaced or progressive)input; and 3-5) three composite or S-videoinputs. For Input #1, the HDTV componentvideo to RGB converter converts HDTV YUVinput signals to RGB, eliminating externalswitching by a display device. Input #2 alsoaccepts RGB with composite video sync froma SCART connector, which is used onEuropean DVD players.

The “D” (digital) versions and “AD”(audio and digital) versions—DVS 406 D andDVS 406 AD—also support SDI signals on asixth BNC input. Using 3.5 mm captive screwconnectors, the “A” (audio) versions—DVS406 A, DVS 406 AD—accept stereo audiosignals (balanced/unbalanced) for each video input.

The DVS 406 offers quad-standard videodecoding compatibility. It uses a digital, four-line adaptive comb filter to decode NTSC3.58, NTSC 4.43, PAL, and SECAM.

With its 33 available scaled output rates,including HDTV, the DVS 406 is the perfectscaling solution. Each model outputs videosimultaneously on a 15-pin HD connectorand five BNCs. Audio is output on 3.5 mmcaptive screw connectors.

Aspect Ratio and Picture ControlsTo get the most out of video originating in

multiple image formats (16:9, 4:3, and otheraspect ratios), the DVS 406 provides

aspect ratio control. The user can resizeimages to accommodate different aspectratios while maintaining original imagequality. Up to three aspect ratios per inputcan be stored in memory and recalled by thefront panel, RS-232, or optional IR 901remote control.

Brightness, contrast, color, tint, detail,horizontal and vertical sizing, and horizontaland vertical centering are available for finepicture adjustments of any input except forRGB pass-through signal(s). Variable top andbottom vertical blanking eliminates edgenoise caused by tapehead switching andcaptioning.

Control and More...Control is provided via front panel

operation, and RS-232 control. The frontpanel buttons control video and audio inputselection, plus picture adjustments. Allfunctions are available through RS-232.Extron’s Simple Instruction Set (SIS™) is

provided for RS-232 control using third-partycontrol or Extron’s Windows®-based controlprogram. The DVS 406 can also be controlledthrough an optional IR 901 remote.

An executive mode is available forsecuring the DVS 406. This reduced functionmode locks out all front panel functionsexcept for input selections; all functions,however, remain active through RS-232 oroptional IR 901 remote.

The DVS 406 is housed in a rackmountable, full rack width, 1U high, metalenclosure. The 100-240VAC, 50/60 Hz, auto-switchable, internal power supply providesworldwide power compatibility.

With this high performance and feature-packed scaler, rental and stagingprofessionals can maximize image quality,enhance system flexibility, and simplifysystem design for meetings andpresentations.

ITU-T standardization section. They are ATM; H.320and H.323. ATM is sent over T3 lines and is rarelyused. H.320, a family of standards developed forvideo teleconferencing systems uses dedicated ISDNlines; and H.323, known as “Video over IP” or“Videoconferencing over IP,” an umbrella standard formultimedia conferencing on traditional packet-switched LANs. Here’s how H.320 and H.323 breakdown:

H.320: Allows a system from one manufacturer totalk to a system from another manufacturer, just astwo different brands of fax machines can talk to eachother. References H.261 (Video); G.711, G.722, andG.728 (Audio); H.221, H.230, H.231, H.233, H.234,H.242, and H.243 (Control).

H.323: Is an intricate, multifaceted umbrellastandard ratified by the ITU in 1996. It defines themultiple codecs, call control, and channel setupspecification necessary to move audio, video, and dataover connectionless networks. References H.261(Video); G.711, G.722, G.728 (Audio); H.225 (Mux),H.245 (Control Signal).

One school of thought is that H.323 is a great VCmedium because it uses the Internet and doesn’t costanything. However, Ivan Perez, VP of InformationTechnologies at Extron, contends there are key aspectsto consider. “The difference in costs between theH.320 and H.323 is that .320’s costs are mostlyincremental. The installation costs are relativelyinexpensive. The reverse is true of H.323. Usually thehigh cost of the network infrastructure is spread

For this article, we will address standards. Asvideoconferencing (VC) technology has progressed,standards have become a paramount concern. Keyelements have fallen into place to allow thevideoconference “idea” to blossom. In the last coupleof years, considerable growth has occurred as A/Vprofessionals increase their videoconferencing needs.They aren’t just selling product; they are using themedium themselves.

TechnologyVast improvements in VC technology along with a

reduction in equipment costs have fueled proliferationof ISDN (Integrated Service Digital Network) lines in alltypes of organizations. Transmitting with 128k has

become an infrequent practice, as more end-users are

transmitting at speeds of384k or higher.

As increasedbandwidth hasgenerated superioraudio and video,end-users have

placed highexpectations on

optimum performance.Still, the issues of standards

present another hurdle we mustovercome.

that apply to videoconferencing. These fall under the

standard meant for a relatively few intelligentendpoints.

While the light gets brighter at the end of thetunnel, everyone is chomping at the bit, waiting forthis standard to become more reliable, easier to use,and serviceable. We’ve made some major strides withH.320. The VC experience is now a far morecomfortable fit, with a “look and feel” that isdiminishing the distance between participants.

Even as we venture into the H.323 standard, thereare the same stumbling blocks encountered before. Ifyou need to make a call to another individual andshare documents, or discuss specific issues at hand,this talking head scenario could work in an acceptablemanner. But if you want to give a presentation wheredetail is crucial, and you dial a call across the country,leaving your local area network (LAN) for a rush hourtraffic jam on the wide are network (WAN), the qualityof your videoconference will suffer.

The bottom line is that as H.323 continues toimprove, we will eventually embrace its capabilities. It’ssimply a matter of meeting the standards we havecome to expect and demand.

Perez explains how IT managers have a tendency topaint pictures of network equipment upgrades,monitoring and support costs. And those are typicallylocal area network (LAN) costs. Add in the choice ofturning to providers of private wide area network(WAN) networks with gateway connections to yourendpoints, and another “hidden” cost comes to light.

Pushing the StandardsThere are published statistics that corroborate the

general consensus surrounding the use of the H.320standard today. Take note of their projectedpercentages of H.323 within the 5-year span.

Percentage of Use, 20005% - ATM/T386% - ISDN/T1 (H.320)9% - IP (H.323)

Percentage of Use, 20053% - ATM/T324% - ISDN/T1 (H.320)73% - IP (H.323)

Source: “Videoconferencing Industry: Overview,” Frost & Sullivan, June 2001

We can see that the use of the H.323 standard willdramatically escalate as videoconferencing becomesmore widespread. This pertains strictly to NorthAmerica. Europe and Asia are trailing thevideoconferencing trend by approximately two years.

Even as H.323 is becoming a high-profile issuethrough interviews, articles, reviews and hands-onexperience, there is still plenty of room for growth interms of overall quality and functionality. Thebroadband revolution is obviously taking longer thanexpected.

Because H.323 leaves a lot of room forinterpretation, its compliance is no assurance ofinteroperability. For one, there are claims that H.323doesn’t scale. Version 3 of H.323 supposedly hasupdates intended to solve problems present in a

film frame rate to the video field (and frame)rate, the cycle continuously alternatesbetween transferring film frames to threeand then two video fields (hence the term“3:2 pulldown”). The net effect is that when24 film frames are processed, 30 videoframes have been created, so the rates havebeen matched.

Figure 2 shows the conversion from filmto video as in figure 1, but the conversionfrom interlaced video to de-interlaced video(as would be done in a scaler) is added onthe far right. The video fields are now de-interlaced and combined into video frames.Note that the same 3:2 sequence exists.

Figure 3 (on page 23) shows the net effectof this operation. After de-interlacing, eachframe is now shown for 1/60th of a second.Notice that the original film frames (shown asblue and yellow) are represented as videoframes unequally time-wise. As figure 3

process called “3:2 pulldown” is used. PALuses a process called “2:2 pulldown.” Forthis article, 3:2 pulldown will be discussed asan example.

The 3:2 Pulldown ProcessFigure 1 illustrates the method of

transferring each frame of film to video whilematching the film rate to the video rate. Theleft side of the illustration shows the filmframes and the right side shows the videofields created from each film frame.

The first step is to convert film to theindividual video fields. In figure 1, film frame#1 is transferred to three video fields, thenfilm frame #2 is converted to the next twovideo fields, film frame #3 is used to makethree video fields, and so on. To match the

Film Speed Versus Video SpeedYears ago, before television was even a

laboratory experiment, film based camerasand movie projectors had become fairlycommon. At first, film speed (frames persecond) varied depending on the camera andprojector used. Film speeds started at 16frames per second and moved upward overtime. However, in time cameras andprojectors were standardized to operate atthe rate of 24 frames per second. The 24frames per second speed came with theadvent of sound, since this speed wasneeded for good sound reproduction.

Later, when television was developed, thepower line frequency was used as a timingreference. American NTSC television usedthe local 60 Hz power line frequency as areference, to create 30 frames per second,while European PAL television used the local50 Hz power line frequency as the reference,to create 25 frames a second. Keep in mindeach frame is created from two interlacedfields, so the field rate is twice that of theframe rate (two fields make up one videoframe).

So today we have film running at 24frames per second and NTSC televisionrunning at 30 frames per second. For thoseof us who use NTSC, this creates a problemwith transferring film to video. When film isconverted to NTSC video, the frame rateneeds to be matched in order for the film-to-video conversion to take place. To do this, a

True-Rate™ Scaling Technology (patent pending)

Along with the DVS 406, Extron has introduced a new technology called True-Rate. Simply put, True-Rate

technology ends a phenomenon called “jutter,” which is the jumping/stuttering effect seen on video that

was made from film. The jutter effect is a side effect of 3:2 pulldown, the process that is used to convert film

to video. The whole underlying cause of this problem is the fact that film and video run at varying frame rates.

shows, film frame #1 is shown for 1/20th ofa second (three periods of a 1/60th of asecond). Then film frame #2 is shown for1/30th of a second (two periods of 1/60th ofa second). This is a notable difference intime, one that the eye can detect.

One case where the eye can detect theunevenness of 3:2 pulldown is when there ismotion across the screen or when there is apanning scene. As the panning/motionoccurs, it will be noticed that an objectspends more time in one location thananother. It is only 1/60th of a seconddifference, but the eye will notice it. In fact,it can be distracting. The effect is called“jutter” (referring to the jumping orstuttering effect seen in the image).

T E C H C O R N E R

New True-Rate TechnologyTo solve this problem, Extron

developed True-Rate technology. Whenan Extron scaler featuring True-Ratetechnology detects 3:2 pulldown, itapplies a technique that will match thevideo frame rate to the film rate. Tomatch the video rate to the film rate, wecould slow down the video rate, but itwould be too slow and noticeable flickerwould result. On the other hand, wecould make the video frame rate an exactmultiple of the film rate to allow one-to-one correlation. For instance, 48 Hz couldbe used (2 x 24 frames per second), butthis is too slow, and noticeable flicker willresult. The next multiple of 24 frames persecond is 72 (3 x 24 frames per second).Here we have a multiple that allows one-to-one correspondence between the filmframe rate and video frame rate, and thisis fast enough to prevent flicker.

The exact process works by addingvideo frames as needed. Keep in mindthat the original problem is caused by the

Figure 3.

Figure 4.

fact that one frame of film will be shownfor two video frames, while the next willbe shown for three video frames. Thesolution is to add a video frame to eachset of two frames, so that each frame offilm is now shown over three videoframes, thus eliminating the uneveneffect.

The block diagram at the top of Figure 4 (below) shows the overallprocess, from the 3:2 pulldown stage tothe process of de-interlacing the video,and to the application of True-Rate,which eliminates jutter. The net effect isnow each video frame is shown the samelength of time.

The lower section of figure 4 showsthe results. With the True-Rate processadding the frames as needed, the filmframes (shown in blue and yellow) arenow all shown for an equal amount oftime. Therefore, jutter is eliminated, andmotion and panning scenes will nowappear smooth and even.
