Abstract:
Methods, systems, and computer program products are provided to divide code blocks, such as blocks of quantized coefficient of image or video data, into smaller blocks and sub-blocks that can be processed in parallel using layered entropy coding and decoding scheme. This division is accomplished while still encoding the entire code block using the same layered entropy coding scheme.
