Problems solved by technology

In addition, when MBR files are produced, only a limited number of rates can be selected for encoding, and there are few selectable bit rate parameters during playback, which cannot well meet the requirements of bandwidth adaptation.
Finally, playing MBR files requires more streaming media server hardware and software resources, increasing business operating costs
Especially when networking with multiple server clusters, each streaming server requires high performance, which increases operating costs

Embodiment Construction

[0029] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings and examples.

[0030] In Embodiment 1 of the present invention, a kind of stream media code rate control method as shown in Figure 1, comprises the following steps:

[0031] Step s101, the user terminal sends a stream media play request to the stream media server.

[0032] In this step, the user terminal sends a streaming media play request to the streaming media server through the RTSP (Real Time Streaming Protocol, real-time streaming) protocol.

[0033] Step s102, the streaming media server sends the media stream to the user terminal.

[0034] In this step, after the user terminal passes the authentication of the streaming media server, the streaming media server sends the media stream to the user terminal, and the user terminal plays the media stream. When the streaming media server selects the initial sending bit rate of the media stream, it nee...

Abstract

A method for controlling code rate of stream media includes judging whether code rate of media stream sent to user terminal is required to be regulated or not by stream media server according to network state feedback from user terminal, sending original media stream and adaptive parameter to code rate adaptive server by stream media server if it is, using stream media server to receive media stream being processed by code rate adaptive server according to said adaptive parameter and sending received media stream to user terminal. The system and device used for realizing said method are also disclosed.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a stream media code rate control method, system and equipment. Background technique [0002] With the development of communication technology, especially wireless mobile network technology, network bandwidth has been able to meet the needs of real-time streaming media services, and streaming media services have become the development direction of future communication value-added services. In order to make full use of existing network resources and improve user experience at the same time, it is necessary to introduce a QoS (Quality of Service, service quality) control mechanism while developing streaming media services. Especially for wireless networks with widely different bandwidths, the QoS control mechanism can greatly enhance user service experience and increase user attractiveness. [0003] In the prior art, streaming media QoS control is performed in an MBR...
