Streaming media transmission control method, media transmission control method and associated equipment

Abstract

The embodiment of the invention provides a streaming media transmission control method, a media transmission control method and associated equipment. The method of the embodiment comprises the steps that a streaming media client acquires a media indexing file from a streaming media server, the media indexing file is used for segmenting each program in the streaming media server, media quality information and the media code rate information are used for description, and the media quality information is used for representing the media quality of the program segment under the corresponding code rate; the streaming media client selects a code rate assembly of multiple program segments after the current streaming media broadcasting time according to the network situation, the media code rate information and the media quality information; and the streaming media client downloads the program segment corresponding to the code rate according to the code rate assembly of multiple program segments. The embodiment of the invention also provides a streaming media client, a streaming media server, a media transmission control method, a client and a server. The embodiment of the invention can effectively reasonably allocates the bandwidth, so that the comprehensive quality of the streaming media can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a streaming media transmission control method, a media transmission control method, and related equipment. Background technique [0002] Streaming media technology is a technology in which the application layer uses Hypertext Transport Protocol (HTTP, Hyper Text Transport Protocol), and the transport layer uses Transmission Control Protocol (TCP, Transport Control Protocol) to manage data transmission. Streaming media technology can realize streaming media files. "Play while downloading". [0003] In order to improve the adaptability of traditional streaming media technology to bandwidth heterogeneity and volatility, a complete program is generally divided into multiple program segments in the prior art, and each program segment provides versions with multiple code rates. When the streaming media client is on-demand, it can select a program segment with an appropriate code rate...

AI Technical Summary

Problems solved by technology

[0007] Bit rate is an objective indicator of streaming media quality. Generally speaking, the higher the bit rate, the higher the streaming media quality. In other words, when the code rate reaches a certain value, even if the code rate is increased, it will not improve the user experience, and the existing technical solutions can only select the program segment with the code rate closest to the current bandwidth, so that The bit rate of each program segment is close to the current bandwidth, so the streaming media client cannot allocate the limited bandwidth to program segments that require a higher bit rate (such as scenes with fast screen changes and complex background colors). As a result, the media quality of the client is affected, thereby degrading the user experience
