Broadband Network
Multicast IP

• Broadcast Signals are encoded into MPEG-4 or VC-1
  format which can be transmitted _at_1.5 Mbps
• Middleware provides the Electronic Program Guide
  (EPG)
• CPS provides the subscribers right for requested
  channels

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.

• CPS authenticates the subscribers right for
  requested content
• Billing server facilitates the subscriber credit

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

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?

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

23
Technical Parameters

• Jitter lt10 msec (2 msec for HDTV)
• Packet loss lt 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
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
