Studio Content from any format should be
converted to MPEG-4/VC-1 format.
Studio provides equipment for
conversion of Beta tapes and other
formats to MPEG-4 / VC-1
Provides live recording facilities
Provides Video/Audio Switching,
Mixing, Editing facilities
Facilities for Repurposing, Promos,
advertisements etc.

• Edge servers are deployed in the network for high demand content
• Middleware / Content Mgmt. Provide title search for user
• CPS authenticates the subscriber’s right for requested content
• Billing server facilitates the subscriber credit details
• Back office processes – billing, provisioning, activation, monitoring

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
Jitendra Garg DGM(MPLS& IPTV) 23
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
Jitendra Garg DGM(MPLS& IPTV) 33
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
