摘要： Reference pictures received via a video signal are downscaled to a specified resolution by a video encoder/decoder. For each current picture being processed by the video encoder/decoder, the current picture is maintained at its original received resolution, but is divided into blocks. Each block is further divided into sub-blocks, and each sub-block is compared, for a set of specified positions, to a corresponding block of the downscaled reference image to generate a set of candidate motion vectors. The candidate motion vectors are scored according to how closely their corresponding sub-block matches the corresponding block of the reference picture at the corresponding position, and a motion vector for each block of the current image is selected based on the scores. The selected motion vectors are used to process (e.g. encode) the video signal.

摘要： A video encoder employs a relatively small sized cache for motion compensation. A motion search module selects an initial subset of the full reference picture and has it transferred to the cache. For a first set of blocks of a current picture, the motion search module calculates a set of motion vectors using the reference picture subset stored at the cache. Based on the set of motion vectors, the motion search module identifies an offset that indicates a predicted direction of motion. Based on the offset, the motion search module identifies another subset of the reference picture and transfers the identified subset to the cache for calculation of the next set of motion vectors.

摘要： A video processing device encodes an input video stream by dynamically varying an output bit rate for the resulting encoded video stream based on a length of the input video stream. A rate control module receives at least two parameters from an application requesting that the video stream be encoded: a target average bit rate (ABR) and a length of the video stream to be encoded. The rate control module varies the output bit rate according to the complexity of video information in the video stream and the remaining length of the video stream that has not been encoded. In addition, the rate control module constrains the output bit rate to ensure that the ABR is achieved for the entire encoded video stream.
