Abstract

A method for dispatching parallel transmission of stream media data includes setting a sending module on steam media server; setting a sending module and a receiving module separately on each node for receiving stream media data; defining parameters of rate of sending, packet size and number of sending, signal transmission time, time of data overtime and packet loss for father node on receiving module; sending command packet for distributing transmission task simultaneously to each father node according to their network property and their distribution ratio for holding maximum set distribution ratio while network stable transmission state is ensured .

Description

technical field

[0001] A parallel transmission scheduling method for streaming media data belongs to the technical field of streaming media data transmission in networks. Background technique

[0002] Since the media data, especially the video data, has a large volume, it takes a long time for the user to download the entire video file through the network. And if the video is compressed by streaming media technology, the user can watch the movie during the downloading process. The streaming media technology can be watched while watching, and it will not take up a lot of local hard disk space.

[0003] Although streaming media technology saves time for users, it fails to solve users' bandwidth limitations. Although the development of the current video compression technology has greatly reduced the volume of video data, and its demand for bandwidth has also been greatly reduced, but at present, to watch video data with relatively ideal quality, a bit rate of about 400kbps or ...
