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.
[0006] 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

Embodiment Construction

[0025] The basic working principle of the streaming media server of the present invention is: the streaming media server regularly obtains the receiving buffer status and decoding status from the mobile device terminal. During the fast and slow sending process, the streaming media server adjusts the sending speed according to this information, so as to ensure that the media is played with the best effect on the mobile device terminal. The fast sending here refers to increasing the media encoding bandwidth for sending, or increasing the speed of sending data packets. Slow sending refers to reducing the media encoding bandwidth sent. The normal sending speed refers to the media sending speed determined according to the media bandwidth.

[0026] According to above-mentioned principle, the course of work of streaming media server of the present invention is:

[0027] 1. The bandwidth detection module of the mobile device terminal obtains the current bandwidth status through the ...

Abstract

The invention relates to a flow media server with bandwidth adaptive function, wherein it comprises server flow protocol module, bandwidth analyzing module, bandwidth selecting module, document analyzing module, and media sending module. The mobile device timely reports received bandwidth state and media receiving state to the flow protocol module; the flow protocol module sends said information to the bandwidth analyzing module and finds the media bandwidth and sending speed, the media sending module sends it. 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 communication equipment, in particular to a media delivery server. Background technique [0002] Streaming media first appeared on fixed Internet networks. At present, the method for transmitting multimedia information such as audio and video on the network mainly adopts two transmission schemes of downloading and streaming. For the download solution, since large files often require a large amount of storage capacity and are limited by network bandwidth, the download often takes several minutes or even hours, and the delay is very large. For streaming transmission, files such as sound, video or animation are played while being downloaded. When time-based media such as sound are played on the client computer, the remaining part of the file continues to be downloaded from the server in the background, which not only makes the start-up delay appear ten times. It can be shortened by a factor of 100 or 100, ...
