P2p live streaming: where from and where to? - P2P-Zone

vatary · 03-04-06, 07:35 AM

Currently,live streaming based on p2p or grid technology is very hot,some companys have obtained some VC investments.Some media companys ,such as News Group,BBC,have studied this technology and talk about some good or bad results from this technology.

P2p steaming is the latest generation of peer-to-peer technology,which evolved as a way to delivery live audio and video streaming over internet to huge users.Traditional solutions are client-server model ,all users get streaming content from central server,so many servers and much bandwidth are used up,no scalability,no robustness,overhead and too expensive.P2p live streaming solution solves these questions,uses existing desktop computing power and networking connectivity to transfer streaming contents to end users,very cheap,one PC with a ADSL connection maybe broadcast DJ/VJ's voice/video to all over the world,for million users.

Evolution of live streaming technology

The road of p2p live streaming technology include three kinds:Single-tree protocol,Multi-tree Delivery Protocols and Data-Driven Overlay Protocol.

The first applicative scenario in which the peer-to-peer approach to live media streaming was introduced is the large-scale broadcast distribution of non-interactive content: the most significant research papers date back to 2000, with the proposal of the Overcast and Scattercast architectures, which both employ a two-tiered infrastructure (the p2p part of the network is just the core, end-users don't take an active role in the content distribution) to spread the load from a single server to a large pool of supporting nodes.

The other field of interest, which was also explored around the year 2000, was small-scale, multiple source video distribution in cooperative environments with a certain aim at intra-company conferencing and media broadcasting: good results have been achieved by the Narada and Yoid research projects - the first has also been implemented as a commercial product for enterprise-wide brokering systems - which use a mesh-based infrastructure for keeping the global connectivity and managing the distribution trees which relay data streams.

In the following years (2001 to 2004), the research started focusing on completely distributed systems for media broadcast, and the three main branches of this field are fundamentally different in the way they approach the problem: many projects have studied methods which rely on single applicative multicast trees, like SpreadIt , PeerCast ,ESM and NICE , while others have explored approaches based on multiple trees - to obtain a better resiliency to node failures - and appropriate data encodings - to protect the playback quality in case of packet losses - like Splitstream , CoopNet and P2PCast finally, improvements with respect to the plain single-tree based solutions have been proposed with Zigzag and Bullet .

June ,2004,a HongKong student Zhang xin-yan and his partners published a paper "A Data-driven Overlay Network for Peer-to-Peer Live Media Streaming" and released coolstreaming software.From this time,many p2p live streaming system based this paper released ,such as pplive,ppstream,vatata,etc.please see fig2,this is a evolution of live streaming technology.

P2p live streaming system

Mostly p2p live streaming systems structure are like CDN,relay , proxy and delivery streaming contents to users' desktop PC.Users will also bear a responsibility as p2p streaming network node and make the grid network more stable and fluid,but CND nodes must be a server with much bandwidth,it's very expensive.

Now listing some p2p streaming systems,divide open source/freeware systems into commercial systems.

P2p live streaming business model

Using p2p live streaming technology will help two kinds companys' business. One is traditional media company,such as Cable-TV,satellite-TV,film company,Broadcast Radio,etc.These companys can use this technology delivery its multimedia contents to PC users through internet,develop a new market without much costs.Another companys are more important,these company maybe create a new kind entertainment market for billions internet user.This is really internet-TV,it's more interaction,more entertainment,and more global. These new players will grow fast,maybe take place of traditional media company. Of course,personal users can use p2p live streaming technology to setup yourself TV or Radio station,like own your blog space,this is new way to show yourself on internet.

P2p live streaming technology also brought bad news,copy rights are still a problem.Wall Street Journal said:"China has become the hotbed of a new technology that distributes live television signals over the Internet, exposing the world's pay-TV operators to the kind of online piracy that has plagued the music and movie businesses.",this report listed some Chinese p2p streaming companys,Roxbeam,PPlive,Sop,PPstream,etc.A German P2P system called Cybersky-TV, one of the first to use the technology, stopped distributing its streaming software after being slapped with a court injunction.

Conclusion

This's all,I use Vatata's poem as end of this article.

The horse passed west land
So build a village at the end of water
And make a camp fire
Begin to sing a drunken song.

P2p live streaming technology must be a nice future!

CyberSky/cybertelly seems to have some legal troubles. There is a good chance they will prevail as I seem to recall that after a long and expensive legal battle the German courts allowed advert removing deivces to be sold.

In the meantime the software is available at
http://www.cybertivi.host.sk/downloa...oad/index.html

via zeropaid

There is a system for pirating satellite TV using Dreambox receivers. You receive the encrypted satellite TV signal with a dish as normal and you get the small datastream that allows you to decrypt it over the internet. Someone somewhere has a pile of recievers with genuine cards. Lots of people can watch a channel with only one card for that channel and without the high traffic of streaming video.

>let's try

It's certainly time for someone to review all this competing streaming software and write and article about what works best.
