Problems solved by technology

However, adjusting the transmission rate of the streaming media stream through congestion control information can only make the overall transmission rate of the stream uniform, and there is still the problem of excessive transmission rate in a short period of time, and the transmission rate is not stable, which is easy to cause network congestion and packet loss And other issues

Abstract

The invention discloses a method and a device for adjusting the code stream sending speed of a streaming media, and relates to the field of streaming media. According to the method and the device disclosed by the invention, on one hand, the reference sending time of data packets to be sent is determined according to the information of a code stream, a frame rate and the like, the actual sending time length of the data packets is determined by combining with the execution time used for sending the data packet, then the data packets to be sent are uniformly distributed in the time of the actual sending time length and sent, and the sending speed of the streaming media can be smoothed, the network congestion can be reduced, and the network packet loss can be reduced in case of guaranteeing the overall uniform sending speed; on the other hand, acceleration processing can also be carried out for the data packets in a controllable range when early-warning conditions are achieved, thus playing a smoothing role and avoiding the serious fluctuations of bandwidths.

Description

technical field [0001] The invention relates to the field of streaming media, in particular to a method and device for adjusting the sending rate of streaming media code streams. Background technique [0002] In the streaming media real-time communication business, since the generated bit stream frame data is not uniform in size, in order to effectively prevent network jitter and congestion, the sending end needs to adjust the sending rate of the streaming media bit stream at this time. [0003] At present, the transmission rate of streaming media streams is adjusted through congestion control information. When congestion occurs in the network, the transmission rate of streaming media streams is gradually reduced, and when the congestion is eliminated and the network status is good, the transmission rate of streaming media streams is gradually increased. rate, so that the sending rate of the streaming media stream appears jagged. However, adjusting the transmission rate of ...
