Abstract

There are provided methods and apparatus for multi-view video coding. A video encoder includes an encoder for encoding a block in a picture by choosing between temporal prediction and cross-view prediction to enable a prediction for the block. The picture is one of a set of pictures corresponding to multi-view video content and having different view points with respect to a same or similar scene. The picture represents one of the different view points. A high-level syntax is used to indicate the use of cross-view prediction for the block.

First claim

The invention claimed is:

1. A video decoding method, comprising:
decoding a block in a picture using two cross-view reference picture lists, the picture being one of a set of pictures corresponding to multi-view video content and having different view points with respect to a same or similar scene, the picture representing a current one of the different view points,
wherein the two cross-view reference picture lists correspond to reference pictures having different view points than the current one, wherein a number of cross-view reference pictures and view identifiers corresponding to cross-view reference pictures are signaled in a slice header in the bitstream for each of the two cross-view reference picture lists, and wherein the view identifiers are distinctive in each of the two reference picture lists, and wherein said decoding includes at least one buffer for storing decoded pictures corresponding to multi-view content for different view points of a same or similar scene, and wherein the at least one buffer includes a separate buffer for each of the different view points, and reference pictures in the cross-view reference picture lists are ordered in the same sequence as they appear in the slice header, and wherein syntax in the slice header is used to indicate a coding type for a cross-view prediction.

2. The method of claim 1 , wherein the two cross-view reference picture lists are different than List 0 and List 1 of the International Organization for Standardization/International Electrotechnical Commission Moving Picture Experts Group-4 Part 10 Advanced Video Coding standard/International Telecommunication Union, Telecommunication Sector H.264 recommendation.
