METHODS AND APPARATUS SUPPORTING MULTI-PASS VIDEO SYNTAX STRUCTURE FOR SLICE DATA
First Claim
1. An apparatus, comprising:
- an encoder for encoding at least one syntax data element related to at least two partitions of at least a portion of a picture, wherein the at least one syntax element is encoded within a multi-pass syntax structure, the at least one syntax element belonging to a given class of data, and said encoder 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.

Abstract
There are provided methods and apparatus supporting a multi-pass video structure for slice data. An apparatus includes an encoder 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 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.
