Abstract
A method of video coding includes receiving video data comprising one or more subpictures, signaling, in a sequence parameter set, whether to use a network abstraction unit (NAL) layer identifier as a subpicture identifier, signaling the subpicture identifier in a NAL unit header when the sequence parameter set indicates to use the NAL layer identifier and signaling the subpicture identifier in a slice header when the sequence parameter set indicates not to use the NAL layer identifier, signaling a length of the subpicture identifier, and encoding the video data based on the subpicture identifier.
