Abstract
Official abstract text for this publication.
A method for decoding a compressed video data sequence containing one or more coded pixel blocks. The compressed video sequence is buffered. Prediction information for each of the coded pixel blocks is reviewed. One or more groups of coded pixel blocks are formed based on the reviewed prediction information such that the coded pixel blocks within a given group have similar prediction dependencies and/or at least do not depend on a reconstructed pixel within a group of received pixel blocks to enable parallel decoding. The formed groups are scheduled for processing and subsequently decoded to produce a decoded video data sequence.
First claim
Opening claim text (preview).
What is claimed is: 1. A decoder, comprising: an input device to receive coded video data; a memory device to store decoded reference frames, and a processor configured to assign a first coded pixel block of a frame to be decoded to a decoding group; for subsequent additional coded pixel blocks of the frame, to determine whether the respective subsequent coded pixel block contains a prediction reference that refers to a reconstructed pixel within the decoding group, if not, as…
