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

Abstract

The embodiment of the present invention provides a streaming media transmission control method, a media transmission control method, and related equipment. The method in the embodiment of the present invention includes: the streaming media client obtains the media index file from the streaming media server, and the media index file is used to describe each program segment in the streaming media server using media quality information and media code rate information, and the media quality information It is used to represent the media quality of the program segment at the corresponding bit rate; the streaming media client selects the bit rate combination of multiple program segments after the current streaming media playback time according to network conditions, media bit rate information and media quality information ; The streaming media client downloads the program segment corresponding to the code rate according to the code rate combination of multiple program segments. The embodiment of the present 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 present invention can effectively improve the reasonable bandwidth allocation, thereby improving the comprehensive quality of streaming media.

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 Transfer Protocol (HTTP, Hyper TextTransport Protocol), and the transport layer uses Transmission Control Protocol (TCP, Transport Control Protocol) to manage data transmission. Download and play". [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 in combination with its own network conditions. [0004] When the us...

[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
