Abstract
A method, computer program, and computer system is provided for signaling output layer sets in a coded video stream. Video data having multiple layers is received. One or more syntax elements are identified. The syntax elements specify one or more output layer sets corresponding to output layers from among the multiple layers of the received video data. The one or more output layers corresponding to the specified output layer sets are decoded and displayed.

A method of signaling output layer sets in a coded video stream, executable by a processor, comprising:
- receiving video data having multiple layers;
- identifying one or more first syntax elements specifying one or more output layer sets corresponding to one or more output layers from among the multiple layers of the received video data;
- decoding and displaying the one or more output layers corresponding to the specified one or more output layer sets;
- and
- signaling one or more third syntax elements indicating a subpicture identifier corresponding to each of one or more output layers associated with the one or more output layer sets,
- wherein a subpicture layout is aligned across each of the one or more output layers associated with the one or more output layer sets.
A computer system signaling output layer sets in a coded video stream, the computer system comprising:
- one or more computer-readable non-transitory storage media configured to store computer program code;
- and
- one or more computer processors configured to access said computer program code and operate as instructed by said computer program code, said computer program code including:
- receiving code configured to cause the one or more computer processors to receive video data having multiple layers;
- first identifying code configured to cause the one or more computer processors to identify one or more first syntax elements specifying one or more output layer sets corresponding to one or more output layers from among the multiple layers of the received video data;
- decoding and displaying code configured to cause the one or more computer processors to decode and display the one or more output layers corresponding to the specified one or more output layer sets;
- and
- signaling code configured to cause the one or more computer processors to signal one or more third syntax elements indicating a subpicture identifier corresponding to each of one or more output layers associated with the one or more output layer sets,
- wherein a subpicture layout is aligned across each of the one or more output layers associated with the one or more output layer sets.
A non-transitory computer readable medium having stored thereon a computer program for signaling output layer sets in a coded video stream, the computer program configured to cause one or more computer processors to:
- receive video data having multiple layers;
- identify one or more first syntax elements specifying one or more output layer sets corresponding to one or more output layers from among the multiple layers of the received video data;
- decode and display the one or more output layers corresponding to the specified one or more output layer sets;
- and
- signal one or more third syntax elements indicating a subpicture identifier corresponding to each of the one or more output layers associated with the one or more output layer sets,
- wherein a subpicture layout is aligned across each of the one or more output layers associated with the one or more output layer sets.
