IntroductionNumerous commercial systems now offer services over

the Internet that are similar to traditional cable, or satellite TV.

Live television, time-shifted programming, and content-on demand are all presently available over the Internet.

Increased broadband speed, growth of broadband subscription base, and improved video compression technologies have contributed to the emergence of these IPTV services.

Introduction (continued…)We draw a distinction between three uses of

peer-to-peer (P2P) networks: delay tolerant file download of archival

materialdelay sensitive progressive download (or

streaming) of archival materialreal-time live streaming.

Peer-Division Multiplexing

Here we describe the network architecture of Zattoo, one of the largest production live streaming providers in Europe.

Peer-Division Multiplexing to minimize per-packet processing time of a stream, the Zattoo protocol sets up a virtual circuit with multiple fan outs at each peer.

Existing SystemIn media streaming, the End users may have

different edge bandwidth for data receiving or forwarding, especially in large-scale streaming with hundreds of thousands of users.

Description coding rates have straightforward impact to the delivery performance.

The loss rate of the description will be high.

Zattoo delivery network architecture (proposed system)User first authenticates itself to the Zattoo

Authentication Server. Upon authentication, the user is granted a

ticket with limited lifetime. The ticket is verified for user authorization,

then Rendezvous Server returns to the user a list of peers currently joined to the P2P network carrying the channel, together with a signed channel ticket.

Fig. 1. Zattoo delivery network architecture.

Zattoo peer with IOB.When a peer joins a TV channel, it

establishes a peer-division multiplexing (PDM) scheme, by building a virtual circuit to each of the neighboring peers.

As packets from each sub-stream are stored in the IOB for reassembly to reconstruct the full stream.

Portions of the stream that have been reconstructed are then played back to the user.

RequirementsMINIMUM HARDWARE REQUIREMENTS: System : Pentium IV 2.4 GHz.Hard Disk : 10 GB.Monitor : 15 VGA Colour.Ram : 256 Mb.

SOFTWARE REQUIREMENTS:

 Operating system : - Win XP Professional.Coding Language : - Java.Tool Used : - Eclipse.

ConclusionsWe have presented a receiver-based, peer-

division multiplexing engine to deliver live streaming content on a peer-to peer network.

The same engine can be used to transparently build a hybrid P2P delivery network by adding Repeater nodes to the network.
