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


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?


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

IPTV / VOD Revenue Projections

2008 Estimates Broadband connections(DSL) 17 million IPTV / VOD subscriptions 7 million Broadband ARPU Rs.500/-p.m. IPTV / VOD ARPU Rs.600/-p.m. Broadband Yearly Revenue Rs.850 Cr. IPTV / VOD Yearly Revenue Rs.420 Cr.

Highly volatile numbers


Major Challenges …. Pricing pressure – CAS rollout Content Cost high due to low volumes.

Revenue share models workable. Competition with cable operators Emerging Market - Capacity

Anticipation ?? Comprehensive marketing strategy Regulatory issues
