Method and apparatus for video coding

摘要

There is provided a slice header prediction method and apparatuses for 3D video encoding and decoding. In some example embodiments the following features can be derived from the header prediction method. Any decoding order of texture and depth view components may be supported. Also flexible prediction of syntax elements from any slice header appearing earlier in decoding order within the same access unit is allowed. The prediction can be turned on or off on view component basis. The syntax elements of the slice header may be categorized in a few sets and the use of the prediction as well as the prediction source for each set can be individually controlled. By using some example embodiments of the method all syntax elements of the slice header may be predicted.

1. A method comprising:
encoding an uncompressed picture into a coded picture comprising a slice, the encoding comprising:
classifying syntax elements for the slice into a first set and a second set;determining syntax element values for the first set and the second set; andencoding the first set selectively in a first group of slices parameter set or a slice header, wherein said encoding of the first set comprises one of the following: providing an indication of an inclusion of the respective first set from another group of slices parameter set; or encoding the syntax element values of the first set; and
encoding the second set selectively in a second group of slices parameter set or the slice header, wherein said encoding of the second set comprises one of the following: providing an indication of an inclusion of the respective second set from another group of slices parameter set; or encoding the syntax element values of the second set, wherein the method further comprises forming at least one group of slices parameter set from the slice header of a texture view component of a base view.
