Abstract: Methods and systems are provided for encoding and decoding a video stream. Each picture in a video stream can be divided into slices, each of which contains a contiguous row of macroblocks. All the blocks corresponding to a single video component within each slice can then be used as the basis for encoding the picture. By decomposing each picture into slices, the video stream can be efficiently converted for displays of varying size and/or quality. The encoded bitstream can include a slice table to allow direct access to each slice without reading the entire bitstream. Each slice can also be processed independently, allowing for parallelized encoding and/or decoding.

Abstract: Embodiments of the present invention provide a coding system that codes data according to a pair of coding chains. A first coding chain generates coded video data that can be decoded by itself to represent a source video sequence of a small size, such as a size sufficient to support the real time playback and display features of a video editing application. The second coding chain generates coded video data representing supplementary data, which when decoded in conjunction with the coded video data of the first coding chain, yields the source video sequence for full-size display. The output of the first coding chain may be stored in memory in a file structure that can be accessed independently of the second chain's output and, therefore, it facilitates real time decoding and playback.

Abstract: A method and system are provided to minimize the size and complexity of bitstreams associated with encoded data by using a new compression scheme. An entropy encoder receives a list of run/data value pairs and entropy encodes separately the runs and data values, selecting their codewords according to length and magnitude, respectively, and catenates the resulting codeword pairs—run codeword first—in an encoded bitstream.

Abstract: A method and system are provided for encoding a plurality of integers with variable-length code tables constructed by combining a plurality of structured code tables. Each code table has an associated set of integer values; the sets are disjoint and exhaustive, so that every integer appears in exactly one set. An integer is encoded using the codebook associated with the set in which the integer appears.
