Abstract: A method for encoding and decoding a video signal having frames with blocks comprised of pixels. The method reduces the complexity of the video signal to be encoded by applying a filter scheme to the input data stream in an encoder and later reversing the filter scheme in a decoder. A number of filter schemes may be tested to determine the best filter scheme that most reduces the number of distinct color values per color plane. The best filter scheme is used to filter the data to be encoded. Filter information of the best filter scheme is included in the encoded data to enable the decoder to identify the best filter scheme in order to apply the best filter scheme in reverse to re-create the original data stream.

Abstract: A method of compressing video data having at least one frame having at least one block and each block having an array of pixels is provided. The method transforms the pixels of each block into coefficients and creates an optimal transmission order of the coefficients. The method also optimizes the speed of processing compressed video data by partitioning the data bitstream and coding each partition independently. The method also predicts fractional pixel motion by selecting an interpolation method for each given plurality or block of pixels depending upon at least one metric related to each given block and varies the method from block to block. The method also enhances error recovery for a current frame using a frame prior to the frame immediately before the current frame as the only reference frame for lessening quality loss during data transmission. Enhanced motion vector coding is also provided.

Abstract: A method for decoding a stream of encoded video data is disclosed. The video stream includes partitions that have been compressed using lossless encoding. Each partition includes rows that have also been encoded using intra-frame or inter-frame encoding, for example. 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.

Abstract: A method for decoding compressed video information is disclosed. The video information can include a plurality of frames each having a plurality of blocks. The method includes reading from the video information a segment map that associates blocks in the frame with four segment identifiers. Each segment identifier is associated with one or more segment parameters, such as quantization parameters, loop filter type, loop filter strength and sub-pixel interpolation filter. The blocks in each segment are then decoded using the associated segment parameters. Segment parameters can persist to following frames unless overwritten by a subsequent frame. A frame can also include a bit suppressing segmentation, in which case default parameters are used for all blocks in the frame.
