Testing IPTV
Two areas of focus when testing IPTV
Infrastructure Testing – verifying the capacity and behavior of the network and each network element
Video Quality Testing – assessment of the end user Quality of Experience (QoE)
Testing procedure:
Benchmark each area separately
Test video quality under varying loads at different points in the network
Increase the number of Video Streams and Subscribers to cause the QoE to degrade –this creates a deployment benchmark for customers
Jitendra Garg DGM(MPLS& IPTV)

21. Infrastructure Testing
Bandwidth
Can the infrastructure handle hundreds of channels?
Channel zapping
How fast can a user change channels?
Channel validation
Is the correct information being received?
Benchmarking
How do real servers compare to the Lab environment?
Triple-Play
What is the effect on Voice and Data?
Jitendra Garg DGM(MPLS& IPTV)

22. Infrastructure Testing
Infrastructure Testing Methodology:
Bandwidth capacity to handle expected size and number of multicast streams
Network and network element performance and scalability
Vary subscriber profiles, background traffic and measure:
Number of multicast streams supported
% packet loss
Maximum number of subscribers supported, etc.
Channel change behavior
Create profiles to emulate subscriber behaviors, background traffic and measure:
Channel change (zapping) time
Join failures
Redundant joins
Packet loss
Join/leave latencies, etc

Technical Parameters
Jitter : <10 msec (2 msec for HDTV)
Packet loss : < 0.1 % (I-frame loss critical)
Zap time : 2 to 3 seconds
Latency : Critical
For HDTV… 8 Mbps
For SDTV… 2 Mbps
