The invention relates to a method of parallel video coding and a device. The invention comprises a host processor and a plurality of coder, the host processor is used for dividing present frame in the video sequence fixedly into macroblocks, distributing all macroblocks to one or a plurality of band groups according to the preset rule; according to the rule of processing load to balance between a plurality of coders, the band group of present frame is devided into one or a plurality of sub-band groups according to the raster scanning sequence; all sub-band groups of present frame which are determined by division and code configuration parameters are sent to a plurality of coders respectively, then parallel sub-band groups of present frame is coded by the coders, outputs codes and parameters respectively; finally, gathering codes and parameters output by each coder, further coding sub-band groups, frames and sequences, outputting whole sequence code. Thereby, the method and the device of the invention are suitable to realtime high definition video code.
Description
technical field [0001] The present invention relates to the technical field of video coding, in particular to a parallel video coding technology. Background technique [0002] Video coding technology is to compress digital video information so that it can be transmitted and stored more efficiently. Video coding is the core technology of multimedia data processing. [0003] At present, video compression coding standards mainly include: the moving picture coding standards H.261 and H.263 formulated by the Video Coding Experts Group (VCEG) of the International Telecommunication Union (ITU-T); the moving picture expert group ( MPEG) video coding standards MPEG1, MPEG4-Part2; video coding standards MPEG2 / H.262, H.264 / AVC (MPEG4-Part10); In addition, there are VC-1 (formerly WMV-9) and the video coding standard AVS1.0-P2 formulated by the Audio Video Standards Group (AVS). [0004] The basic framework of MPEG (Moving Picture Experts Group), JVT (MPEG Joint Experts Group) and V...
