Abstract: A system, apparatus, and method for decoding a video signal having a plurality of frames including a current frame. Decoding the video signal includes generating an alternate reference frame, detecting an error in the current frame and reporting the detected error, receiving a recovery frame in response to reporting the detected error, wherein the recovery frame is encoded using the alternate reference frame; and decoding the recovery frame using the alternate reference frame. The alternate reference frame occurs prior to the current frame in the video signal and is other than a frame immediately prior to the current frame.

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 system, apparatus, and method for decoding a video signal having a plurality of frames including a current frame. Decoding the video signal can include generating an alternate reference frame having a first quality level, determining a boost value indicative of a second quality level higher than the first quality level, determining whether to apply the boost value to the alternative reference frame, and selectively applying the boost value to the alternative reference frame if it is determined to apply the boost value to the alternative reference frame. The alternate reference frame can occur prior to the current frame in the video signal and other than a frame immediately prior to the current frame.
