PPStream

PPStream - streaming p2p Internet TV

PPStream is a network for live media streaming, or you can call it a P2P Streaming Internet TV. In principle it's similar to BitTorrent(BT).

It can broadcast TV programs stably and smoothly to broadband users. Compared to traditional stream media, PPStream adopts p2p - streaming technology and supports full-scale visit with tens of thousands of users online. Its client software can be used as a webpage or as a desktop program.

Currently the majority of PPStream TV channels are from China, Hong-Kong, Taiwan and Singapore.

How to use PPStream

1. Download the PPStream software and install it. Alternatively, you can also view it online.
2.Run PPStream and you'll see 3 panes. The left one is the channel list in which the channels are sorted according to popularity.

Hint: During soccer or football live broadcast, you can be quite sure that TV channels
broadcasting them will be ones of the most popular (thus they will be on top of the channel
list).

Hint: The channel list has 3 columns: TV channel name, stream quality (measured in Kbps),
and the number of users connected to this channel. The more users connected to the channel,
the more likely you will be able to watch it smoothly and stably.

The majority of channels have a description (albeit most of them are in Chinese language). To view a channel description, right click on the channel, and click on the last item.
Hint: Save the URL address of your favorite TV channel as a shortcut with your own
description (it helps a lot when you don't know Chinese language).

The right pane contains a list of recommended TV programs, TV schedule links and announcements. On top of it is a highly recommended show.

Hint: If you click on a link with an icon of a clock and a calender, you will see the full
schedule for the channel (albeit in Chinese language). You may also schedule your application
to switch to a particular channel at a particular time.

And in the center there is an embedded Windows Media Player in which TV stream is played once a channel is chosen.

P2P Streaming Television

All streaming media players buffer segments of audio/video streams before actually showing them. After buffering a segment a media player shows it, and at the same time the media player starts buffering the next segment. Ideally there shouldn't be any sound or video frame freezes. Unfortunately in reality internet servers and internet channels often get overloaded and users get sound and/or video frame freezes. That is where peer-to-peer (p2p) technology can help. Software like PPLive, PPStream, Coolstreaming, QQLive, SopCast, Feidian, TV Ants allows users to watch streaming media (TV channels) based on BitTorrent (BT) p2p technology.

PeerStreaming is an on-demand peer-to-peer (P2P) media streaming system. The behavior of a PeerStreaming client is very much like an ordinary media player: it streams and plays whatever media the user desires, starting at whatever point he/she desires. However under the hood, the media is delivered from multiple peers to the client. The serving peers can be the media server, but more commonly are the clients that have received the media in a previous streaming session.Leveraging the network and storage resources of the P2P network and retrieving a majority part of the media from nearby peers, PeerStreaming greatly improves the streaming media quality, reduces the server load, and eases the traffic on the network.

There are many kinds of software program , based on P2P technology, allow you to watch streaming television or other media on your PC via the Internet.Users take a closer look at the program and its capabilities. The software is available for free download on the site.
