Problems solved by technology
In the above solution, due to transmission delay factors, the cache adjustment is not accurate enough, and even increases the fluctuation of the server's code stream output; moreover, the cache changes caused by network jitter will automatically balance without adjustment
Due to the existence of network delay and network jitter, the existing control method is not accurate enough, and will additionally cause fluctuations in the output of the server

The invention discloses a streaming media transmission rate control method, system and streaming media server, and relates to the technical field of streaming media. The method calculates the cache condition of the client at the streaming media server, adjusts the output code rate according to the client's cache as needed, calculates the average value of the local cache at the client, and corrects the system deviation by the server according to the average cache of the client reported by the client. The invention provides a new control mechanism of streaming media transmission rate, realizes stable data buffering at the client end, ensures smooth code stream output at the server end, and improves the quality of streaming media services.
Description
technical field [0001] The invention relates to the technical field of streaming media, in particular to a streaming media sending rate control method, system and streaming media server. Background technique [0002] Streaming media technology refers to the technology in which multimedia data is transmitted from the server to the client through the network in a streaming manner, and the client can play while receiving the media stream. Streaming media file formats support media formats for streaming and playback. The streaming transmission method is to divide multimedia files such as video and audio into compressed packages through a special compression method, and transmit them continuously and in real time from the server to the user. In a streaming system, users don't have to wait until the entire file is downloaded to see the content as in non-streaming playback, but only need a few seconds or tens of seconds of start-up delay. Use the corresponding player on the user ...
