摘要： A system (and a method) are disclosed for intelligently fetch one or multiple reference blocks from memory for each block to be motion compensated or motion estimated within a video processing system. The system includes a reference block configuration evaluation unit and a motion compensation memory fetching unit. The reference block configuration evaluation unit analyzes the reference block configuration of the block being motion compensated with a plurality of reference block configurations of its neighboring blocks. In response to a reference block configuration evaluation result, the reference block configuration evaluation unit decides the configuration of reference blocks to be fetched from a memory. The motion vector memory fetching unit fetches the number of reference blocks for motion compensation accordingly.

摘要： A system (and a method) are disclosed for a video processing system cascading multiple transcoders. The system includes a first transcoder, a second transcoder and an optional third transcoder. The first transcoder is a pre-processing transcoder configured to preprocess an input video stream into a first bitstream in a first video format. The second transcoder is a primary transcoder configured to transcode the first bitstream into a second bitstream in a second video format. The third transcoder comprises a post-processing transcoder configured to further transcode the second bitstream into a third bitstream in a third video format. Pre-processing and post-processing the input video stream by the cascaded transcoders allows the system to more efficiently and quickly transcode the input video stream. Pre-processing and post-processing the input video further improves processing efficiency and speed and also increases throughout of coding processing.
