Transcript of IPTV for People who AREN’T Engineers
IPTV for People whoAREN’T Engineersby Shaun Carlson
Arvig
How a most Network Engineers feel when teaching the “non-technically inclined”… and how the “non-technically inclined” feel when listening …
Alternate Title:“How to talk to a Network Engineer”
What to expect from this presentation
Don’t expect:•to build an IPTV network in your home•a network engineer to ask you to fix the DHCP server because STB client leases are overloading the network•to shout out the textbook definition to Protocol Independent Multicasting (PIM) on command
DO expect:•to have basic familiarity with what an IPTV system involves•to better appreciate the technical jargon used by your engineering team•a network engineer to be annoyed by all of your new questions after this session
What is IPTV?One Definition: Internet Protocol television (IPTV) is a system through which television services are delivered using the Internet protocol suite over a packet-switched network such as the Internet, instead of being delivered through traditional terrestrial, satellite signal, and cable television formats.
ITU-T Definition: IPTV is defined as multimedia services such as television/video/audio/text/graphics/data delivered over IP based networks managed to provide the required level of quality of service and experience, security, interactivity and reliability.
Alternate Definition: IPTV is another way of getting television to the house using a method very similar to delivery of Internet to the home.

Let’s break it down (30,000 ft. view)

Head End
What does a Head End Do???
* Not a real head end… (I hope)
Simply put, it provides the video to the network
So… how does it do that exactly?
Satellite Dishes
IP Feeds
Encoders
Transcoders
MPEG 2/4
Middleware Servers
This is where Multicast Originates!
Wait… what the heck is Multicast???
Transport Network
Ok, I get the Head End Now… kinda… and what did you say a transport network is?
I’ve got the whole world, in my hands…
Basically, it’s how we move the video (TV Signal) from the Head End to the rest of the world, or in this case customer hand off point
How important is the transport network?
Well… the transport network can have a HUGE impact on the quality of the video and what the customer actually sees
Transport Network, some terms
Multicast
Unicast
Latency
Jitter
Loss
Routing
Router
Switch
VLAN
IP AddressQuality of Service (QOS)
IGMP
Failover
Time to geek out a little…
Transport Network, a little latency

Access Network & Home
Great! My head hurts and I’m feeling underwhelmed… what’s next???
What’s in a home?What does the customer expect?
What factors can affect the “in home” experience?
How is IPTV different than analogue cable in the home?
Access Network & Home, terms…
Are you starting to hate technology terms yet?
DSLAM
ONT / NID
Residential Gateway (RG)
Set Top Box (STB)
DHCP
Quality of Experience (QoE)
The end user experience is the primary and most
important goal, it’s how you will retain the customer
Expectations, Effects & Opportunities
IPTV vs. Over the Top Video (OTT)
Multiple Services in the Home,
i.e. Revenue Retention
Network Performance
Metrics and Monitoring
Tiling and Freezing and Green Bars,
Oh My!
Q&AThank you for your time, your understanding, your patience and your sanity… I promise I will return your sanity after questions!
