Abstract
Official abstract text for this publication.
Techniques are described for encoding and decoding digital video data using macroblocks that are larger than the macroblocks prescribed by conventional video encoding and decoding standards. For example, the techniques include encoding and decoding a video stream using macroblocks comprising greater than 16×16 pixels. In one example, an apparatus includes a video encoder configured to encode a coded unit comprising a plurality of video blocks, wherein at least one of the plurality of video blocks comprises a size of more than 16×16 pixels and to generate syntax information for the coded unit that includes a maximum size value, wherein the maximum size value indicates a size of a largest one of the plurality of video blocks in the coded unit. The syntax information may also include a minimum size value. In this manner, the encoder may indicate to a decoder the proper syntax decoder to apply to the coded unit.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of decoding video data, the method comprising: decoding one or more syntax elements associated with a sequence of pictures, comprising: decoding a first syntax element representative of a maximum size for the blocks of the sequence of pictures; and decoding a second syntax element representative of a minimum size for the blocks of the sequence of pictures, wherein values for the first and second syntax elements represent a range of sizes…
