Aspects of the disclosure provide a method, an apparatus, and non-transitory computer-readable storage medium for video decoding. The apparatus includes processing circuitry that is configured to decode a supplemental enhancement information (SEI) message that indicates independent region output information. The independent region output information indicates an independent region that is independently decodable in a current picture. The processing circuitry determines the independent region in the current picture based on offset information and dimension information of the independent region in the independent region output information. The processing circuitry decodes the determined independent region irrespective of whether the entire current picture is decoded. The processing circuitry outputs the decoded independent region based on a position indicated by the offset information and a size indicated by the dimension information of the independent region.
