Abstract
There is included a method and apparatus comprising computer code configured to cause a processor or processors to perform obtaining video data comprising data of a plurality of semantically independent source pictures, determining, among the video data, whether references are associated with any of a first access unit (AU) and a second AU according to at least one picture order count (POC) signal value included with the video data, and outputting a first quantity of the references set to the first AU and a second quantity of the references set to the second AU based on the at least one POC signal value.
Claims20
A method performed by at least one processor, the method comprising:
- obtaining video data comprising data of a plurality of pictures;
- determining, among the video data, whether references are associated with any of a first access unit (AU) and a second AU;
- and
- outputting a first quantity of the references set to the first AU and a second quantity of the references set to the second AU based on at least one picture order count (POC) signal value,
- wherein the video data comprises video parameter set (VPS) data identifying a plurality of spatial layers of the video data which are shared across layers of an adaptive parameter set (APS), a picture parameter set (PPS), and a sequence parameter set (SPS),
- wherein a same value space of values of adaptation_paramater_set_id and aps_params_type of the APS is shared across the layers, and
- wherein a same value space of sps_video_parameter_set_id is shared in the SPS.
An apparatus comprising:
- at least one memory configured to store computer program code;
- at least one processor configured to access the computer program code and operate as instructed by the computer program code, the computer program code including:
- obtaining code configured to cause the at least one processor to obtain video data comprising data of a plurality of pictures;
- determining code configured to cause the at least one processor to determine, among the video data, whether references are associated with any of a first access unit (AU) and a second AU;
- and
- outputting code configured to cause the at least one processor to output a first quantity of the references set to the first AU and a second quantity of the references set to the second AU based on at least one picture order count (POC) signal value,
- wherein the video data comprises video parameter set (VPS) data identifying a plurality of spatial layers of the video data which are shared across layers of an adaptive parameter set (APS), a picture parameter set (PPS), and a sequence parameter set (SPS),
- wherein a same value space of values of adaptation_paramater_set_id and aps_params_type of the APS is shared across the layers, and
- wherein a same value space of sps_video_parameter_set_id is shared in the SPS.
A non-transitory computer readable medium storing a program configured to cause a computer to:
- obtain video data comprising data of a plurality of pictures;
- determine, among the video data, whether references are associated with any of a first access unit (AU) and a second AU;
- and
- output a first quantity of the references set to the first AU and a second quantity of the references set to the second AU based on at least one picture order count (POC) signal value,
- wherein the video data comprises video parameter set (VPS) data identifying a plurality of spatial layers of the video data which are shared across layers of an adaptive parameter set (APS), a picture parameter set (PPS), and a sequence parameter set (SPS),
- wherein a same value space of values of adaptation_paramater_set_id and aps_params_type of the APS is shared across the layers, and
- wherein a same value space of sps_video_parameter_set_id is shared in the SPS.
