INTRODUCTION Live Streaming

Peer Division Multiplexing

A number of commercial peer-to-peer systems for

live streaming have been introduced in recent

years.

Zattoo is one of the largest production live

streaming providers.

It has about 60000 concurrent users on a single

channel but still maintains a delay for just 2 to 5

sec.

Before going to know more about our project lets first know some terms

Peer –to-peer(P2P) network is a distributed application architecture that partitions tasks workloads among peers.

PROBLEM STATEMENTWHO

• Who does the problem affect? Live stream viewers

WHAT

• What is the issue? Delay in channel switching

WHEN

• When does the issue occur? Flash crowd scenarios

WHERE

• Where is the issue occurring? field of live streaming in IPTV

WHY

• Why is it important to fix the problem? To reduce delay

This can be easily explained using the 5 ‘W’s concept

Delay: 10sec

Increase in the passion for live stream viewing resulted in the increased no. of viewers , pressurizing the servers causing large delays. Hence the concept of peer division multiplexing came in to existence to reduce the delay.

OBJECTIVE

To present a receiver based, peer-division multiplexing engine

To build a hybrid P2P/CDN delivery network by adding repeater nodes

Utilization of available uplink bandwidths

Improvised network stability through error correction and packet retransmission

PDM and adaptive PDM providing competition to digital satellite TV in terms of

EXISTING SYSTEMTree- based systems

The video source server is connected to all users participating in the session by a multicast tree .

Disadvantages

PROPOSED SYSTEM

As packets from each sub-stream arrive at the peer, they are stored in the IOB (packet buffer)for reassembly to reconstruct the full stream.

IOB is used by 1) Local media player .2) Local file if recording is supported.3) Other peers.

Repeater nodes are allocated to improve the uplink bandwidth, which acts as a bandwidth amplifier.

Retransmission helps a peer recover from transient network congestion.. 04/13/2023 05:43:29 PM


CHALLENGES requiring timely and sustained streaming delivery to

all participating peers

involving bandwidth requirements of hundreds of kilobits per second and even more for higher quality video

corresponding to tens of

thousands of users simultaneously participating in the streaming with highly peer dynamics (join and leave at will)

especially flash crowd

Real-time constraints

Performance-demanding

Large-scale and extreme peer dynamics

Join Phase

04/13/2023 05:43:30 PM


Live Data Streaming The Zattoo system rebroadcasts live TV,

onto the Internet.

The system carries each TV channel on a

separate peer-to-peer delivery network

Join only one peer-to-peer network at any

one time.

Peer-division

Multiplexing Building a virtual circuit to each

of the neighboring peers.

Maintaining virtual circuits,

each packet is forwarded

without further per-packet

handshaking between peers.

Storing packets in the IOB for

reassembly to reconstruct the

full stream.

Playback reconstructed parts of

stream

04/13/2023 05:43:30 PM


Search Phase Joining peer sends out a SEARCH message .

The SEARCH message contains the sub-stream indices.

The sub stream indices is usually represented as a

bitmask of n bits, where n is the number of sub-streams

defined for the TV Channel.

Join Phase joining peer sends JOIN requests to each potential

neighbor.

The JOIN request lists the sub-streams for which the

joining peer would like to construct virtual circuit with

the

potential neighbor.

Spread out the load amongst the peers and

to speed up error recovery

FUTURE ENHANCEMENTS

Reducing the cost on encoding and decoding

Streaming error free data Make delay to zero seconds and provide the

justification for live streaming
