Problems solved by technology

[0002] With the popularization of variable bit rate video encoding methods, when encoding video, due to different video contents, the real-time bit rate of the encoded video block will fluctuate up and down at the target bit rate
Based on existing data statistics, the average jitter range of video blocks can reach 20%-40%, which will lead to great decision-making errors in adaptive bit rate scheduling decisions
In the live stream, since the live content is generated in real time, it is impossible to prefetch the live stream information, so this phenomenon is more prominent

Abstract

The invention provides a multi-code-rate scheduling method and a multi-code-rate scheduling device. The multi-code-rate scheduling method comprises the following steps: acquiring coding information of a current video block from a current live broadcast stream; predicting an output code rate of each preset code rate gear for transcoding the current video block based on the coding information of the current video block; selecting a code rate gear from the preset code rate gears according to the predicted output code rate; and transmitting information about the selected bit rate gear. According to the invention, the real-time code rate of the video code stream is predicted based on the granularity of the block, and the coding information of the video is considered during prediction, so that the video block with the corresponding code rate is more accurately scheduled during the adaptive code rate scheduling decision.

Description

technical field [0001] The present disclosure relates to the field of communication technology, and in particular, to a multi-bit rate scheduling method and multi-bit rate scheduling device, and a training method and training device for a bit rate prediction network. Background technique [0002] With the popularization of variable bit rate video encoding methods, when encoding video, due to different video contents, the real-time bit rate of encoded video blocks will fluctuate around the target bit rate. Based on existing data statistics, the average jitter range of video blocks can reach 20%-40% at present, which will lead to great decision-making errors in adaptive bit rate scheduling decision-making. In the live stream, since the live content is generated in real time, it is impossible to prefetch the live stream information, so this phenomenon is more prominent. Contents of the invention [0003] The present disclosure provides a multi-bit-rate scheduling method and ...
