1. 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.
