    摘要: A system and method for encoding and decoding a video image having a plurality of frames is disclosed. The method includes a previously reconstructed frame that is segmented to create an alternate reference frame used to encode a current frame. The segments of the previously reconstructed frame are assigned motion parameters, which are used to compile the alternate reference frame. The current frame is encoded and the segmentation parameters and motion parameters are transmitted in the bitstream. The segmentation parameters and motion parameters can be used by a decoder to recreate the alternate reference frame in order to decode the encoded current frame.

    摘要: A system and method for encoding and decoding a video image having a plurality of frames is disclosed. The method includes a loop filter, which is used to reduce blocking artifacts in reconstructed frames. A quality value is determined for each block in the reconstructed frame and each associated predictor block. A variable incremental loop filter strength is calculated for each inter-predicted block using at least one of the quality values. The variable incremental loop filter strength is used during encoding by the loop filter to filter the reconstructed frame.

    摘要: Methods for reducing blocking artifacts at the boundary between adjacent blocks reconstructed from a frame of compressed video information are disclosed herein. The frame includes a prediction stage parameter and a residual error attribute with respect to at least one of the blocks. One method includes reconstructing the at least one block based on the prediction stage parameter and the residual error attribute, categorizing the at least one reconstructed block into one of a plurality of categories based on the prediction stage parameter and the residual error attribute, identifying a filter strength value for the category in which the at least one reconstructed block is categorized based on at least one of the prediction stage parameter or the residual error attribute associated with that category, and filtering the boundary adjacent to the at least one reconstructed block using the identified filter strength value.

    摘要: Decoding a stream of encoded video data involves partitions that have been compressed using lossless encoding. Each partition includes rows that have also been encoded using intra-frame or inter-frame encoding. During the decoding process, two or more of the partitions are entropy decoded on two or more processors in parallel, except that partitions containing adjacent rows in the frame are decoded with an offset so that at least a portion of the output of the entropy decoding of one partition can be used as input in the entropy and intra/inter-frame decoding of the other.
