Claim Text:
1. A method for decoding video data, the method comprising: decoding, from a bitstream, a first video coding layer (VCL) network abstraction layer (NAL) unit in decoding order in an access unit, wherein the access unit includes the video data for reconstructing at least one picture; decoding, from the bitstream, a second VCL NAL unit in decoding order in the access unit; decoding, from the bitstream, a supplemental enhancement information (SEI) message of a particular type in the access unit prior to decoding, from the bitstream, the first VCL NAL unit, wherein SEI messages contain information associated with processing of the video data; and decoding, from the bitstream, a copy of the SEI message of the particular type in the access unit after decoding, from the bitstream, the first VCL NAL unit and prior to decoding, from the bitstream, the second VCL NAL unit, wherein content of the copy of the SEI message of the particular type in the bitstream is restricted to be identical to content of the decoded SEI message of the particular type.
