A flow media system

Abstract

This invention relates to a flow media system including a server end providing flow media content on the Internet and multiple customer ends playing the flow, media arranged into peer-to-peer network nodes, in which, said server end includes a media content server, WEB server and a flow media server and in obtaining program flow media data to be transmitted to the customer end of peer-to-peer network nodes, said customer end constitutes a WEB analyzing unit interacted with the WEB server, a flow media transmission unit and a broadcast unit in which, the transmission unit gets the issued program flow media data from the server and provides them to other peer-to-peer nodes.

Description

technical field [0001] The present invention relates to streaming media technology on the Internet, more specifically, the present invention relates to a streaming media system implemented on the Internet. Background technique [0002] In the case of limited network bandwidth of the Internet, how to transmit huge multimedia data in real time, streaming media technology provides a good solution. The so-called streaming media refers to the way that users play multimedia data while downloading through the network or a specific digital channel. The current streaming media system usually includes a streaming media server and client. The huge multimedia data is converted into a streaming media file format that can be transmitted in various bandwidth environments, enters the streaming media server, and transmits the streaming media data to the client according to various real-time protocols, and the client uses the player to restore the streaming media data for multimedia informat...

Problems solved by technology

But the disadvantage is that the bandwidth and server cost of the above-mentioned streaming media system are expensive. For example, for ADSL broadband network users with 512kbps, the bandwidth of the client is enough to realize the streaming audio and video of approximate VCD quality

However, for streaming media servers, the bandwidth and server costs required to achieve near-VCD-quality video broadcasting are still very expensive.

A general server bandwidth of 100M can only support 300 people watching a 300kbps video broadcast at the same time, and this method is unacceptable for nearly 100 million Internet users in China. Currently, there are two ways to solve the server-side bandwidth and server load. One is to use video coding technology with a higher compression ratio, and the other is to use more efficient distribution technology to reduce server bandwidth consumption. The effect of the first method is very limited, even if the most advanced H.264 coding technology is used , also only improves performance by 60%

The second method can be realized through multicast or CDN, but it requires a lot of hardware cost

The problem faced by network streaming media is that when users increase, servers and bandwidth need to be invested accordingly, and the cost is proportional to the increase in users
