Abstract

In a video processing system, a method and system for high speed video encoding using parallel encoders are provided. A delimiter may break up a video sequence into encoding groups that are transferred to a plurality of parallel encoders. The parallel encoders may process and transfer intra-coded pictures in the encoding groups to previous parallel encoders or may process and transfer last predictive pictures to next parallel encoders. When intra-coded pictures are transferred, the encoding group may correspond to that of a GOP structure. When predictive pictures are transferred, the encoding group may end in at least one bidirectional-predictive picture. The parallel encoders process the transferred intra-coded pictures or transferred predictive pictures to generate a plurality of parallel outputs. An assembler assembles an encoded video output from the parallel outputs based on timing information. A controller controls the operation of the delimiter, the parallel encoders, and the assembler.
