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 of video encoding performed by at least one processor, the method comprising:
- 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,
- wherein determining whether the references are associated with any of the first AU and the second AU further comprises setting the first quantity of the references to the first AU, in response to determining that each of the first quantity of the references respectively comprises one of a plurality of POC values less than the at least one POC signal value, and
- wherein setting the second quantity of the references to the second AU, in response to determining that each of the second quantity of the references respectively comprises one of a second plurality of POC values equal to or greater than the at least one POC signal value.
An apparatus for video encoding, the 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 semantically independent source 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 according to at least one picture order count (POC) signal value included with the video data;
- 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 the at least one POC signal value,
- wherein determining whether the references are associated with any of the first AU and the second AU further comprises setting the first quantity of the references to the first AU, in response to determining that each of the first quantity of the references respectively comprises one of a plurality of POC values less than the at least one POC signal value, and
- wherein setting the second quantity of the references to the second AU, in response to determining that each of the second quantity of the references respectively comprises one of a second plurality of POC values equal to or greater than the at least one POC signal value.
A non-transitory computer readable medium storing a program configured to cause a computer to:
- obtain video data comprising data of a plurality of semantically independent source pictures;
- determine, 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
- 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 the at least one POC signal value,
- wherein determining whether the references are associated with any of the first AU and the second AU further comprises setting the first quantity of the references to the first AU, in response to determining that each of the first quantity of the references respectively comprises one of a plurality of POC values less than the at least one POC signal value, and
- wherein setting the second quantity of the references to the second AU, in response to determining that each of the second quantity of the references respectively comprises one of a second plurality of POC values equal to or greater than the at least one POC signal value.
