US 2013/0279576 A1 · VIEW DEPENDENCY IN MULTI-VIEW CODING AND 3D CODING

Abstract

This disclosure described techniques for coding layer dependencies for a block of video data. According to these techniques, a video encoder generates layer dependencies associated with a given layer. The video encoder also generates a type of prediction associated with one or more of the layer dependencies. In some examples, the video encoder generates a first syntax element to signal layer dependencies and a second syntax element to signal a type of prediction associated with one or more of the layer dependencies. A video decoder may obtain the layer dependencies associated with a given layer and the type of prediction associated with one or more of the layer dependencies.

Dependent claims

A method of decoding video data, the method comprising:

obtaining, from a coded bitstream, layer dependencies associated with a given layer;
and
obtaining, from a coded bitstream, a type of prediction associated with one or more of the layer dependencies.

Dependencies are inferred from the claim text.
