Abstract

The invention discloses a multi-node low-delay parallel encoding method for 8K ultra-high definition. It adopts master-slave multi-node encoding, video encoding is based on slice encoding, divides a complete frame to be encoded into several slices, assigns different encoding nodes for encoding, and limits each slice to contain a certain number of integer CTU lines, the number of lines Variable, dynamically adjusted according to the encoding time of each node. After each node is encoded, the encoded code stream is sent back to the master node, and the master node is splicing the code stream data into a complete frame. The beneficial effects of the present invention are: Realize 8K real-time encoding in formats such as HEVC and AVS2, increase the encoding performance and reduce the encoding delay by adding an encoding server, and can balance the encoding time of the master-slave encoding nodes to achieve the optimization of the overall system, And with the lowest latency.

Description

technical field

[0001] The present invention relates to the technical field of video decoding, in particular to a multi-node low-latency parallel encoding method for 8K ultra-high definition. Background technique

[0002] HEVC is the latest generation of video coding standard released by the International Telecommunication Union (ITU-T) in 2013. Compared with the previous generation coding standard H264, the compression efficiency of HEVC has doubled, which can greatly reduce the 8K ultra-high-definition video that is currently popularized. bit rate, reducing bandwidth consumption.

[0003] AVS2 is the latest generation standard for ultra-high-definition video applications released by China in December 2016. The coding framework of AVS2 is similar to HEVC, and its coding efficiency is slightly better than HEVC. At present, the AVS2 video standard has become the only video coding standard adopted by the State Administration of Radio, Film and Television of China, and has br...
