Abstract
A method of decoding is provided. The method includes receiving a video bitstream including a picture unit (PU), the PU including a picture header (PH) network abstraction layer (NAL) unit having a picture header NAL unit type (PH_NUT) and an associated video coding layer (VCL) NAL unit, the PH_NUT signifying that a layer identifier (ID) of the PH NAL unit is equal to a layer ID of the associated video coding layer (VCL) NAL unit and a temporal ID of the PH NAL unit is equal to a temporal ID of the PU; and decoding a coded picture from the PU to obtain a decoded picture.
Claims20
A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors of a video processing apparatus, cause the video processing apparatus to:
- receive a video bitstream including a picture unit (PU), the PU including a picture header (PH) network abstraction layer (NAL) unit having a picture header NAL unit type (PH_NUT) and an associated video coding layer (VCL) NAL unit, the PH_NUT signifying that a layer identifier (ID) of the PH NAL unit is equal to a layer ID of the associated VCL NAL unit and a temporal ID of the PH NAL unit is equal to a temporal ID of the PU;
- and
- decode a 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 of a video processing apparatus, cause the video processing apparatus to:
- generate a picture unit (PU) including a picture header (PH) network abstraction layer (NAL) unit having a picture header NAL unit type (PH_NUT) and an associated video coding layer (VCL) NAL unit, the PH_NUT signifying that a layer identifier (ID) of the PH NAL unit is equal to a layer ID of the associated VCL NAL unit and a temporal ID of the PH NAL unit is equal to a temporal ID of the PU;
- and
- encode the PU into a video bitstream.
A non-transitory computer-readable recording medium storing a bitstream that, when parsed by a coding device, is used by the coding device to generate a picture, the bitstream comprising:
- a picture unit (PU), the PU including a picture header (PH) network abstraction layer (NAL) unit having a picture header NAL unit type (PH_NUT) and an associated video coding layer (VCL) NAL unit, the PH_NUT signifying that a layer identifier (ID) of the PH NAL unit is equal to a layer ID of the associated VCL NAL unit and a temporal ID of the PH NAL unit is equal to a temporal ID of the PU.
A decoding device, comprising:
- a memory containing instructions;
- a processor coupled to the memory, the processor configured to implement the instructions to cause the decoding device to:
- receive a picture unit (PU) including a picture header (PH) network abstraction layer (NAL) unit having a picture header NAL unit type (PH_NUT) and an associated video coding layer (VCL) NAL unit, the PH_NUT signifying that a layer identifier (ID) of the PH NAL unit is equal to a layer ID of the associated VCL NAL unit and a temporal ID of the PH NAL unit is equal to a temporal ID of the PU;
- decode a coded picture from the PU to obtain a decoded picture.
