Control method and device for streaming media transmission

Abstract

The invention discloses a control method and device for streaming media transmission, and belongs to the technical field of communication. The method comprises the steps that a streaming media adjusting request sent by a receiver is received, wherein the streaming media adjusting request comprises information of a to-be-adjusted parameter, and the information of the to-be-adjusted parameter is determined by the receiver on the basis of the buffer zone usage rate and a coordination service parameter set; a target parameter corresponding to the information of the to-be-adjusted parameter in thecoordination service parameter set is determined, wherein the coordination service parameter set is determined through consultation of a transmitter and the receiver; and the target parameter is written into a physical layer of the transmitter, and streaming media is transmitted on the basis of the target parameter. The buffer zone usage rate of an application layer is taken as an adjustment factor for physical layer parameter adjustment, therefore, selection of the parameter of the physical layer depends on feedback of the receiver, the method can better adapt to a complex and variable wireless environment, and then the better entity transmission mode is selected; and in addition, the method is independent of the application layer and the physical layer and has the certain compatibility with the existing standard.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for controlling streaming media transmission. Background technique [0002] Streaming Media refers to media formats, such as audio, video or multimedia files, that are played continuously and in real time on the network using streaming technology. Streaming media technology is also called streaming media technology. The so-called streaming media technology is to compress continuous video and audio information and put them on the website server. It is a network transmission technology that you can watch and listen to while watching and listening, instead of waiting for the entire compressed file to be downloaded to your computer. [0003] In the wireless streaming media playback system, due to the instability of the network environment, the data transmission rate is unstable. Although the existing mechanism will first create a buffer on the user's compute...

Problems solved by technology

The existing processing method does not take the two into consideration, which may cause the transmission to not reach the optimal state in some cases

For example, when the buffer is in a saturated state, but the current channel is in good condition and the packet loss rate has not reached the threshold, the physical layer still follows the faster transmission rate and encoding rate, which will cause the data transmission rate of the corresponding application layer to decrease. Faster, but the buffer pool at the receiving end is saturated, resulting in more packet loss
