What is IPTV?

• Internet Protocol Television(IPTV)is a system
  where a digital television service is delivered
  using Internet Protocol over a network
  infrastructure, which may include delivery by a
  broadband connection. A general definition of
  IPTV is television content that, instead of being
  delivered through traditional broadcast and cable
  formats, is received by the viewer through the
  technologies used for computer networks.

Multicast

• Class D is used for Multicast.
• The multicast group ID numbers are in the range
  224.0.0.0 through 239.255.255.255 .
• The format of a class D IP address
• A multicast group address is combination of the
  high-order 4 bits of 1110 and the multicast group
  ID.
• Multicast only apply to UDP.

9
Multicast Address

• The mapping of a class D IP address into Ethernet
  multicast address
• Region A means that low-order 23 bits in the
  Ethernet address are copies from the low-order 23
  bits of the multicast group ID.
• Region B means that these 5 bits in the multicast
  group ID are not used to from the Ethernet
  address .
• The high-order 24 bits of the Ethernet address
  must be 01005e , and the 25th bit must be 0

10
Internet Group Management Protocol

• A protocol is needed for multicast routers to
  know if any hotsts on a given LAN belong to a
  given multicast group IGMP
• Format of a IGMP message

Audio Video Interleave

• Audio Video Interleave (AVI)is a derivative of
  the Resource Interchange File Format (RIFF),
  which divides a file's data into blocks, or
  chunks.
• hdrlthe file header and contains metadata about
  the video, such as its width, height and frame
  rate.
• movithe actual audio/visual data that make up
  the AVI movie.
• idx1the offsets of the data chunks within the
  file.

DirectShow System
23
Filter Graph

• Filter

24
Writing a DirectShow Application

• The application creates an instance of the Filter
  Graph Manager.
• The application uses the Filter Graph Manager to
  build a filter graph. The exact set of filters in
  the graph will depend on the application.
• The application uses the Filter Graph Manager to
  control the filter graph and stream data through
  the filters. Throughout this process, the
  application will also respond to events from the
  Filter Graph Manager.
