Abstract

The invention provides methods and apparatus supporting a multi-pass video structure for slice data. An apparatus includes an encoder (300) for encoding at least one syntax data element related to at least two partitions of at least a portion of a picture. The at least one syntax element is encoded within a multi-pass syntax structure. The at least one syntax element belongs to a given class of data. The encoder (300) encodes the at least one syntax data element with respect to all partitions of at least the portion of the picture prior to encoding a next class of data, wherein later coded data classes, including the next class, have at least one of an explicit coding and an implicit coding of at least one of a casual dependency and a non-casual dependency with respect to earlier coded data classes coded earlier than the next class.

Description

[0001] Cross reference of related applications [0002] This application claims the priority of U.S. Provisional Application Serial No. 60 / 943,406 filed on June 12, 2007, the entire contents of which are incorporated herein by reference. Technical field [0003] The present invention generally relates to video encoding and decoding, and more specifically, to a method and device supporting a multi-channel video syntax structure for slice data. Background technique [0004] In some coding strategies, the coding of syntax elements in frame blocks (for example, macroblocks, subblocks, and / or blocks) depends on or depends on the entire neighborhood (causal or non-causal according to the coding scan order) The data assigned to the syntax element. Typical macroblock data coding, such as in the International Organization for Standardization / International Electrotechnical Commission (ISO / IEC) Moving Picture Experts Group-4 (MPEG-4) Part 10 Advanced Video Coding (AVC) Standard / International ...
