PPS.tv (PPStream) is a Chinese peer-to-peer streaming video network software. Since the target users are on the Chinese mainland, there is no official English version, and the vast majority of channels are from East Asia, mostly Mainland China, Japan, Hong Kong, Taiwan and Singapore. Programmes vary from Chinese movies to Japanese anime, sports channels, as well as popular American TV and films.
It had an 8.9% market share in China in Q3 2010, placing it third - behind Youku and Tudou.
It can broadcast TV programs stably and smoothly to broadband users. Compared to traditional streaming media, PPS adopts P2P-streaming technology and supports high-volume traffic; several hundred thousand users can watch a live stream at 300-500 kbit/s using only one server with a 5-10 Mbit/s connection.
However, the nature of peer to peer serving means that each user of the system is also a server. The upload speed of standard home broadband connections is usually a fraction of the download speed, so several upload sources may be required by each additional peer. Additionally, on services with high contention ratios or poorly configured switches, large numbers of people attempting to use the service may slow all internet usage to unusable speeds. Acting as an upload server to the limit of ones upload bandwidth increases the round trip time for webpage requests, making web browsing while using PPS.tv difficult.
