Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A non-transitory computer-readable medium storing instructions that when executed by a processor, perform a method comprising: receiving encoded image data organized into a plurality of slices, each slice representing a portion of the encoded image data, wherein each of the plurality of slices includes encoded image data generated from run length coded transform coefficients of the image data, the transform coefficients of each block in the portion scanned a…
