  • Patent number: 11750843
    Abstract: Aspects of the disclosure provide a method, an apparatus, and non-transitory computer-readable storage medium for video decoding. The apparatus includes processing circuitry configured to receive a first supplemental enhancement information (SEI) message including scalability dimension information (SDI). The first SEI message includes SDI of a plurality of views in a multiview bitstream including a coded video sequence (CVS) with a plurality of layers. The processing circuitry determines a value of a first syntax element sdi_view_id_val[ ] in the first SEI message. The first syntax element sdi_view_id_val[ ] indicates a view identifier (ViewId) of a layer in the plurality of layers. The processing circuitry determines, based on the first syntax element sdi_view_id_val[ ], a target layer of the plurality of layers to which a second syntax element of a second SEI message applies. The first syntax element sdi_view_id_val[ ] indicates a view of the plurality of views associated with the second syntax element.
