PPLive: Product of the future
My choice for a product of the future is "PPLiv" which is a peer-to-peer streaming video network created in the People's Republic of China.
How does it work?
It is part of a new generation of P2P applications, that combine P2P and IPTV, called P2PTV. All of its TV program signals are transmitted from cable television network to the internet by digitalization if needed.
- After a user selects a TV station from the list, which is accessed by right-clicking the PPLive icon in the Microsoft Windows system tray, the program will then connect to peers and buffer the stream. PPLive typically uses ports 8008 TCP and 4004 UDP to connect to peers.
- When the buffer is reasonably full, PPLive launches your media player, either RealPlayer or Windows Media Player, pointing it to read a stream from a local port (usually 8080).
- Closing down your Media player will not end the stream. The PPLive program will remain in the background streaming data until you close it from the tray or change the channel.
Benefits
With the popularity of broadband network and P2P technology, users can now watch streamed television programs from their computer screens. Furthermore, a lot more programs are recorded and replayed on the P2P TV network like some of the airing American hit shows such as LOST, CSI, Desperate Housewives etc. The whole video stream on this network are contributed by all its users and no one is heavily burdened for downloading or uploading.
Shortcomings
However, this program is almost only well-known to mainland Chinese users and most of the TV programs are from local Chinese stations. But as the developers launched its English version, more and more overseas users are joining in this network and foreign programs like Star Sports and National Geographic have been newly introduced into their test channel list recently.
Future
As illustrated by the P2P technology itself, the more users use it, the higher quality and streaming speed the users can enjoy. My opinion is that in 3 or 5 years, this program can cover almost 90% of Chinese local TV programs and some major foreign channels too like CNN, BBC, Discovery Channel etc. Therefore, only the revenue level gained from advertisement will be soaring high due to the large population of Chinese internet users which already exceeded 10 million in 2005.
