Abstract: At lease a computer program product is provided for efficiently encoding or decoding a video frame. The computer program product when executed by one or more processors configures the one or more processors to compress or encode the different video subsections within the video frame with different compression methods. The visual artifact is reduced between the different video subsections encoded or compressed with the different compression methods within the video frame.

Abstract: A video coding system includes a decoder configured to decode an encoded reference picture, a primary memory, and a secondary memory configured to store the decoded reference picture. The video coding system also includes a logic device configured to extract motion vectors for generating a predicted picture of the reference picture and to store the extracted motion vectors in memory bins. The reference picture includes a plurality of predefined regions and each memory bin stores motion vectors for a particular region of the plurality of predefined regions. For each of the plurality of predefined regions of the reference picture, the logic device is configured to use the memory bin corresponding to a reference region to read the reference region from the secondary memory and write the reference region into the primary memory. The written reference region and the motion vectors of the corresponding memory bin are used to spatially translate the written reference region into the predicted picture.

Abstract: A method and system are provided for code normalization and byte construction. A plurality of subsets of bits is extracted from a first input. Each of the subsets of bits has a bit width equaling a number of leading zeros from a second input variable. Further, a consecutive sequence of the plurality of subsets is stored in a memory. In addition, the consecutive sequence of the plurality of subsets is read from the memory if a third input release flag is established.

Abstract: A method stores, in a first memory location in a context weight update engine in an arithmetic encoder, a context weight value. The method also stores, in a second memory location in the context weight update engine in the arithmetic encoder, a context weight adjustment value. Further, the method reads, in a first clock cycle, the context weight value and a first binarization value from the first memory location. In addition, the method writes, in a second clock cycle, the context weight adjustment value and a second binarization value into the first memory location. The second binarization value is distinct from the first binarization value.

Abstract: At least a computer program product comprising computing instructions stored on a non-transitory computer storage medium is provided. The computer program product is provided for efficiently encoding or decoding a video frame to smooth out or reduce visual distortions such as visual artifact between different video subsections encoded with different compression methods within a video frame. In addition, an improved memory storage is provided for applying a raster scan search strategy for finding a reference image for the input video frame by applying a shift-based input addressing scheme to write to the memory storage and a corresponding shift-based output addressing scheme to read from the memory storage.

Abstract: A method, a video processing system, and an electronic device are disclosed. A video transcoder may decode a compressed video data frame creating a decoded video data frame. The video transcoder may embed a network presentation timestamp in the decoded video data frame. The video transcoder may re-encode the decoded video data frame creating a transcoded video data frame. A field programmable gate array may compare the network presentation timestamp with a transcoder presentation timestamp to determine a timestamp offset.

Abstract: A method for high/low usage is provided. The method receives a macroblock data structure and a syntax element at a digital signal processing engine. Further, the method classifies the syntax element as high use or low use. In addition, the method sends the syntax element from the digital signal processing engine to a logic unit, distinct from the digital processing engine, for binarization if the syntax element is high use.
