Bandwidth adapting system of streaming media

Abstract

The invention relates to a flow media bandwidth adapting system, which comprises flow server, media provider, and mobile device, wherein the flow server comprises server flow protocol module, bandwidth analyzing module, bandwidth selecting module, document analyzing module and media sending module; the mobile device comprises terminal flow protocol module, wireless module, bandwidth detecting module, buffer module and play module; the mobile device via wireless module and bandwidth detecting module timely reports received bandwidth state and media receiving state to the server flow protocol module; the server flow protocol module sends said information to the bandwidth analyzing module to find the media bandwidth and sending speed, to be sent by the media sending module. The invention can automatically adjust the sending speed and code bandwidth of media document via the network state and media receiving state, to improve relative play effect.

Description

technical field [0001] The invention relates to the technical field of computer network application systems, in particular to a network bandwidth adaptation system. Background technique [0002] Mobile streaming media services can be divided into the following two categories according to the playback mode. [0003] (1) Online playback: the terminal player obtains streaming media data from the streaming media server in real time, and plays while downloading. The streaming media content does not need to be stored on the user's terminal device. If the user needs to play the same content multiple times, the data needs to be retrieved from the streaming server each time. For online content, since it is played while downloading, the playback effect depends to a large extent on the network bandwidth, so it is necessary to select appropriate compression parameters to produce content according to the actual bandwidth of the operator's network. [0004] (2) Downloading and playing: ...

AI Technical Summary

Problems solved by technology

The network environment often changes. When the network transmission bandwidth is lower than the media encoding bandwidth, congestion, packet loss and transmission delay will occur, and the playback terminal will experience interrupted playback or mosaic phenomena, which will affect the user's media playback experience.

[0011] Under the wireless network, due to the movement of the mobile device terminal, the attenuation of the wireless transmission signal and the wireless bandwidth being occupied by voice or other services with higher priority at any time, the bandwidth of the wireless link used by the mobile device terminal fluctuates greatly, and the transmission bit error rate high
