SIGNALING OF PICTURE HEADER PARAMETERS
A method, computer program, and computer system for encoding or decoding video data, and indicating, with a syntax element, types of slices for all slices of a coded picture, the syntax element being coded using an unsigned integer.
1 . A method of decoding video data, the method being performed by at least one processor and comprising:
indicating, with a syntax element, types of slices for all slices of a coded picture, the syntax element being coded using an unsigned integer; and
decoding the video data based on the types of slices indicated via the syntax element.
2 . The method of claim 1 , wherein for the coded picture, only related syntax elements are coded.
3 . The method of claim 2 , wherein when all slices of the coded picture are indicated as including intra-prediction, no inter-prediction syntax elements are coded.
4 . The method of claim 1 , wherein picture header related syntax elements are included in a slice layer raw byte sequence payload network abstraction layer unit; and
a flag is used to indicate the presence of the picture header related syntax elements in the slice layer raw byte sequence payload network abstraction layer unit.
5 . The method of claim 1 , wherein the types of the slices may be inferred from a decoded access unit delimiter value.
6 . The method of claim 1 , wherein the types of the slices may be inferred when signaled in high level syntax.
7 . The method of claim 1 , wherein the types of the slices may be inferred based on a number of rectangular slices in the coded picture.
8 . The method of claim 1 , wherein the syntax element is a 0-th order Exp-Golomb-coded syntax element.
9 . The method of claim 1 , wherein the syntax element is a 2 bit syntax element configurable with three statuses.
10 . The method of claim 1 , wherein the syntax element is a 2 bit syntax element configurable with four statuses.
11 . An apparatus for decoding video data, the apparatus comprising:
at least one memory configured to store computer program code; and
at least one processor configured to access the at least one memory and operate according to the computer program code, the computer program code comprising:
indicating code configured to cause the at least one processor to indicate, via a syntax element, types of slices for all slices of a coded picture, the syntax element being coded using an unsigned integer; and
decoding code configured to decode the video data based on the types of slices indicated via the syntax element.
12 . The apparatus of claim 11 , wherein the indicating code is configured to indicate the types of slices such that, for the coded picture, only related syntax elements are coded.
13 . The apparatus of claim 12 , wherein the indicating code is configured to indicate the types of slices such that when all slices of the coded picture are indicated as including intra-prediction, no inter-prediction syntax elements are coded.
14 . The apparatus of claim 11 , wherein the indicating code is configured to indicate the types of slices such that picture header related syntax elements are included in a slice layer raw byte sequence payload network abstraction layer unit; and
a flag is used to indicate the presence of the picture header related syntax elements in the slice layer raw byte sequence payload network abstraction layer unit.
15 . The apparatus of claim 11 , wherein the indicating code is configured to indicate the types of slices such that the types of the slices may be inferred from a decoded access unit delimiter value.
16 . The apparatus of claim 11 , wherein the indicating code is configured to indicate the types of slices such that the types of the slices may be inferred when signaled in high level syntax.
17 . The apparatus of claim 11 , wherein the indicating code is configured to indicate the types of slices such that the types of the slices may be inferred based on a number of rectangular slices in the coded picture.
18 . The apparatus of claim 11 , wherein the indicating code is configured such that the syntax element is a 0-th order Exp-Golomb-coded syntax element.
19 . The apparatus of claim 11 , wherein the indicating code is configured such that the syntax element is a 2 bit syntax element configurable with three statuses.
20 . A non-transitory computer-readable storage medium storing instructions that cause at least one processor to:
indicate, with a syntax element, types of slices for all slices of a coded picture, the syntax element being coded using an unsigned integer, and
decode the video data based on the types of slices indicated via the syntax element.
