Video over IP TrainingCompany Overview



Video over IP Training

Why monitor video at all?• “So quiet you can hear a pin drop!” – US Sprint 1986

– Voice customer are LESS demanding

• Consumers are less forgiving when it comes to poor video quality compared to voice calls or data connections– More demanding since HD

• Very little loss can have a detrimental effect on video and the viewers Quality of Experience (QoE)



Given good quality source video, Packet Loss is the only thing an IP transport network can do to affect

video quality.

MDI = DF : MLR Make sure to check the QualityBEFORE making millions of copies

Video over IP TrainingPrinciples of Video over IP



Jitter on a single flow can and will lead to changes in behavior on other flows.

Cumulative Jitter does not directly affect video quality, but it is an indicator

of impending loss.

VIDEO & AUDIO COMPRESSION



Video over IP TrainingVideo and Audio Compression

• Compression Overview

• Video Compression• Key to Compression: Remove Redundancy

• Video Compression Formats

• MPEG Compression Technologies

• MPEG Video Compression

• MPEG Audio Compression



Video over IP Training The Need for Compression

• Storage Requirements– Digital storage costs are decreasing significantly– Still be very expensive to store uncompressed TV data – A two-hour SD television program ≈ 200GB

• Bandwidth Requirements– Transmitting uncompressed data significant distance is extremely difficult

• Uncompressed Standard Definition (SD) digital video requires > 200 Mb/s• Uncompressed High Definition (HD) digital video requires > 1Gb/s

• Processing Power / Hardware Requirements– Processing large amounts of video data (storage) in real-time (bandwidth)



• The goal of video compression is to reduce the quantity of data used to represent video content without substantially reducing the quality of the picture.

The generalized process of compressing digital video for delivery overtransport networks where they are decoded back into digital or analog video

Video over IP Training Video Compression



• Video compression algorithms take advantage of several Types of Redundancy to reduce the size of the Video Stream.

• Spatial Redundancy– Pixels can be encoded in groups (macro blocks)– Color and Brightness of neighboring pixels often have similar values

• Temporal Redundancy– Changes in an objects location and motion are normally very small from video frame to

frame

• Coding Redundancy– Patterns and common motions often form in video

• Perceptual Coding Redundancy– The human eye cannot perceive minute differences in color and brightness

Video over IP Training Key to Compression: Remove Redundancy

Fewer Bits (storage) & Fewer Bits/second (bandwidth)



• MPEG generally takes analog or digital video signals and converts them to packets of digital data that are more efficiently transported over a network

• The MPEG system consists of two layers : – System Layer (timing information to synchronize video and audio) – Compression Layer (includes audio and video streams) .

• A frame is a single image from a video sequence.• An I frame (initial, intra) is a frame that is compressed solely based in the information contained

in the frame.• A P frame (predicted) is a frame that has been compressed using the data contained in the

frame itself and data from the closest preceding I or P frame.• A B frame (bi-directional predicted) is a frame that has been compressed using the data from

the closest preceding I or P frame and the closest following I or P frame.• A Group of Pictures or GOP is a series of frames consisting of a single I frame and zero or more

P and B frames.

• The order video frames are transmitted can be different than the order they are displayed

• A typical GOP in display order is: B1 B2 I3 B4 B5 P6 B7 B8 P9 B10 B11 P12

• The corresponding bitstream order is:I3 B1 B2 P6 B4 B5 P9 B7 B8 P12 B10 B11

• MPEG can also use a variable GOP to better deal with complex video (not shown). This concentrates I frames together during complex scenes

Video over IP Training MPEG Compression: I, P, B Frames & Group of Pictures



• Every packet counts

– Video and Audio CODECs remove large amounts of redundancy

– Highly compressed data streams are created

– Very small interruptions in the data stream can significantly reduce video quality

• 1st Principle.: Given good quality source video, Packet Loss is the only thing an IP transport network can do to affect video quality.

Constant and Variable Bit Rates

– CBR• Rate of CODEC’s data stream consumption is constant in the decoder• Useful in streaming media when the transport media is a fixed resource • Usually created by stuffing null packets into transport stream

– VBR• CODEC can vary the amount of output data per time segment• More bits are allocated to more complex content• Uses less overall bandwidth• No stuffing

Video over IP TrainingTransport Stream: Constant & Variable Bit Rates



Video over IP Training Program Specific Information & Packet Identifiers (PIDs)

Each Program Stream (in MPEG TS) has unique 13-bit Packet Identifiers (PIDs)

• Standardized PIDs:– Program Association Table (PAT)– Program Map Table (PMT)– Stuffing

• Configurable PID’s– Video– Audio– Data



Assisting the decoder:• Presenting programs on time• At the right speed• Audio synchronization

Programs periodically provide a Program Clock Reference (PCR), on one of the PIDs in the program

• Ports & Sockets• UDP / TCP / RTP

Packet Transport

• Transport Methods• Considerations



Video over IP Training IP Encapsulation

• IP Encapsulation is the process of taking a data stream, formatting it into packets, and adding the headers and other data required

• MPEG over IP Transport streams consist of a series of multiple MPEG TS packets packed inside UDP datagrams

– A typical IP video packet will contain 7 TS packets (188 x 7 = 1316 bytes) – Add Ethernet, IP and UDP headers (46 bytes)– Ethernet Maximum Transmission Unit (MTU) = 1,500 bytes

Standard vs. Jumbo Frame

Standard IP Packet Jumbo IP Packet

Approximately 20% more efficient.



• When video is being transported over an IP network, users need to consider a other factors that can significantly affect the users’ viewing experience

• Multiplexing is a process of combining video streams from different sources into 1 IP flow. Two forms of Multiplexing commonly used today: Time Division and Statistical

• Traffic Shaping consists of various techniques that are used to make video traffic easier to handle on a network. Overall goal is to make an IP flow less prone to sudden peaks in bit rate

• Buffering is basically a collection of memory that is used to temporarily store information prior to taking some action. Buffers can have a major impact of video network performance

• Firewalls are used to control the flow of information between two networks. Need to be aware of the constraints that firewalls impose on video services

Video over IP Training Transport Considerations


Multicasting

IGMP – Internet Group Management Protocol



Video over IP TrainingMulticasting

• Basic Concepts

• Unicasting

• Multicasting

• Joining and Leaving Multicast



• High Bandwidth required between the video source and a number of end-users

• Video source make separate video streams for each recipient

• Reduced Bandwidth requirements between video source and multiple end-users

• Network devices (routers) makes copies of video stream for every recipient

Unicast = one to one

Multicast = one to many

Video over IP TrainingUnicast vs. Multicast



Video over IP Training Unicasting

• Unicasting is the traditional way that packets are sent from a source to a single destination

• Each user who wants to view the video must make a request to the video source.

• The source needs to know the destination IP address of each user and must create IP packets addressed to each user. As the # of viewers increase, the load on the network increases

• Each viewer gets a custom tailored video stream which allows the video source to offer specialized features such as pause, rewind and fast-forward of video.

Unicasting

VODServer



• Multicasting unlike Unicasting, puts the burden of creating streams for each user on that network rather than on the video source

• IP packets are given special IP addresses to be recognized by the network as Mutlicast. IP Address range is Class D: 224.0.0.0 through 239.255.255.255

• IP Multicast uses UDP packets

• IGMP (Internet Group Management Protocol) Protocol controls access to Multicast streams

• User must request to Join and Leave a Multicast program

Video over IPMonitoring & Measurements



Video over IP TrainingVideo over IP Monitoring & Measurements

• Network Impairments

• Flow Behavior

• Video over IP Measurements

• MDI – Media Delivery Index

• Distributed Continuous Program (DCP) Monitoring

• Determining Packet Loss (MLR) on a UDP flow

• Delay Factor (DF) & the effects of a high Delay Factor



• Packet Loss is when an IP packet does not arrive at its intended destination. This can be caused by any number of circumstances: Network Saturation, Network hardware failure, Queuing misconfiguration, etc.

• Packet Reordering occurs in a network when packets arrive in a different order than how they were sent. Since MPEG has a very precisely defined structure and sequence, out of order packets can cause problems

• Delay is going to happen in any network. Two types of delay: Propagation delay and Switching. Propagation is the amount of time to travel from one location to another. Switching delay occurs at any point in the network where a signal needs to be switched or routed.

• Jitter is a measurement of variation in the arrival time of the data packets. Receivers must be built to tolerate jitter and networks should be designed not to create a lot of jitter.

Video over IP TrainingVideo Network Impairments



• The Media Delivery Index (MDI) is a metric that captures the amount of Cumulative Packet Jitter and the amount of Packet Loss of an IP stream. These are the only types of impairments that can be caused by an IP transport network.

• MDI consists of two components:

– Delay Factor : Media Loss Rate

• Delay Factor (DF) is the size of buffer required to transport jittered packets in the network without loss divided by the rate of the media stream – it is proportional to the delay introduced in the system due to the network buffering. The buffer value is expressed in the time (milliseconds) it takes to transmit (drain) the maximum buffer size at outflow rate.

• Media Loss Rate (MLR) is the total Media Packets Lost (per second)

• See RFC 4445 for complete details on how to calculate MDI– http://www.ietf.org/rfc/rfc4445.txt?number=4445

• See Application Notes at: http://www.ineoquest.com/page240.html

Program Clock Reference (PCR)

PCR Jitter vs. IP Jitter

• PCR Jitter (recovered clock inaccuracy)• Serial transport media use a common clock between transmitter and

receiver and can guarantee high accuracy of packet arrival times• Jitter is classified into two categories: PCR accuracy errors (PCR_AC) and

network jitter. These two are then combined into PCR overall jitter (PCR_OJ)

• Ethernet / IP Jitter (variation in expected packet arrival times)• No clock reference for transmission of packets• Because transport can include multiple devices (all with different buffer

cues), there is no guarantee that packets transmitted with a given inter-packet spacing will arrive with the same spacing

• IP jitter is categorized and measured by the Media Delivery Index (MDI) Delay Factor (DF)



• Constant Bit Rate example

– An encoder ideally transmits IP packets at the rate matching the MPEG encoded bit rate as shown here.

– PCR time stamp updates occur every 40 ms in a stream continuously informing a decoder of the MPEG encoded bit rate.

– Constant Bit Rate (CBR) encoding shown here. “Stuffing” bits maintain a constant bit rate even though picture complexity is dynamic.


Constant Bit Rate (CBR)



• Variable Bit Rate (VBR) example

– This example has high DF • The instantaneous,

per packet IP bit rate is bursty and does not track the dynamic encoded PCR bit rate.

– PCR bit rate varies dynamically with picture complexity with VBR since there is no stuffing PID. The instantaneous peak PCR rate may be peak limited (“capped”) by configuration.


Variable Bit Rate (VBR)



• DF continuously tracks the cumulative difference between MPEG bit rate and IP bit rate capturing the stream’s burstiness

• If an IP stream is bursty, its instantaneous bit rate may significantly stress network transport device queues.


Delay Factor (DF)

Properties that must be Measured and Monitored simultaneously to ensure Quality of Video over IP.

• IP packet arrival times where jitter causes delay (Under Runs)

• IP packet arrival times where jitter causes bursts (Over Runs)

• IP packet bit rate average drift/deviation from the Video bit rate

• IP packet loss

• Video packet loss / CC errors

IneoQuest Monitoring and Troubleshooting Solutions



• The biggest problem facing IP Video service providers is unbounded operational expenses (OPEX)– The inability to sustain quality across a distributed service area no matter how much is

spent in OPEX – loosing business model

• OPEX Drivers– Increased call volume – $5.00-$15.00 per call– Increased truck rolls – $100.00 plus per roll– Chronic problems – Problems “come and go”– Lingering problems – No definitive problem resolution; “voodoo” troubleshooting – No visibility – The customer becomes the monitoring and analysis system– Lack of education – New technology presents new problems

• Summary– IP Video distribution presents a new set of problems

• Unique issues that traditional monitoring systems are ill-equipped to handle or detect– IP Video is very different than voice and data

• Requires an evolved multi-dimensional approach to quality and service assurance
