Abstract
A method of decoding is provided. The method includes receiving a picture unit (PU) including zero or one picture header (PH) network abstraction layer (NAL) unit and only one coded picture; and decoding the only one coded picture from the PU to obtain a decoded picture. A corresponding method of encoding is also provided. The method includes generating a PU including zero or one PH NAL units and only one coded picture; encoding the PU into a video bitstream; and storing the video bitstream for communication toward a video decoder.
Claims20
A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors, cause a video processing apparatus to:
- receive a picture unit (PU) including only one coded picture, wherein the PU comprises a set of network abstraction layer (NAL) units that contains zero picture header (PH) NAL units;
- and
- decode the only one coded picture from the PU to obtain a decoded picture.
A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors, cause a video processing apparatus to:
- generate a picture unit (PU) including only one coded picture, wherein the PU comprises a set of network abstraction layer (NAL) units that contains zero picture header (PH) NAL units;
- and
- encode the PU into a video bitstream.
A non-transitory computer-readable storage medium storing a bitstream that, when decoded by a coding device, is used by the coding device to generate a video, the bitstream comprising:
- a picture unit (PU) including only one coded picture;
- and
- a set of network abstraction layer (NAL) units in the PU, wherein the set of NAL units contains zero picture header (PH) NAL units.
