Claim 1:
2. The method of claim 1, wherein the condition comprises: (a) the target output subpicture sub-bitstream includes the second SEI NAL unit that includes a scalable nesting SEI message, (b) a first syntax field in the scalable nesting SEI message is equal to a value that indicates that scalable-nested SEI messages in the scalable nesting SEI message are applicable to same output layer sets as in the target output subpicture sub-bitstream, and a second syntax field in the scalable nesting SEI message is equal to a value that indicates that the scalable-nested SEI messages that apply to specified output layer sets or layers apply only to specific subpictures of the specified output layer sets or layers, and (c) the scalable nesting SEI message is applicable to the same set of layers and subpictures as in the target output subpicture sub-bitstream.
