Claim 14:
15. The non-transitory computer-readable recording medium of claim 14, wherein the one or more syntax elements comprise at least one of:
a first syntax element indicating an alternative initial coded picture buffer (CPB) removal delay delta for an i-th sublayer for a j-th CPB for a NAL hypothetical reference decoder (HRD) in units of a 90 kilohertz (kHz) clock,
a second syntax element indicating an alternative initial CPB removal offset delta for the i-th sublayer for the j-th CPB for the NAL HRD in units of a 90 kHz clock,
a third syntax element indicating, for the i-th sublayer for the NAL HRD, an offset to be used in a derivation of a nominal CPB removal time of the AU associated with the PT SEI message and of one or more subsequent AUs in a decoding order when the AU associated with the PT SEI message directly follows, in the decoding order, an AU associated with a buffering period (BP) SEI message,
a fourth syntax element indicating, for the i-th sublayer for the NAL HRD, an offset to be used in a derivation of a decoded picture buffer (DPB) output time of an intra random access point (IRAP) AU associated with the BP SEI message when the AU associated with the PT SEI message directly follows, in the decoding order, the IRAP AU associated with the BP SEI message,
a fifth syntax element indicating an alternative initial CPB removal delay delta for an i-th sublayer for a j-th CPB for a VCL HRD in units of a 90 kHz clock,
a sixth syntax element indicating an alternative initial CPB removal offset delta for the i-th sublayer for the j-th CPB for the VCL HRD in units of a 90 kHz clock,
a seventh syntax element indicating, for the i-th sublayer for the VCL HRD, an offset to be used in the derivation of the nominal CPB removal time of the AU associated with the PT SEI message and of the one or more subsequent AUs in a decoding order when the AU associated with the PT SEI message directly follows, in the decoding order, the AU associated with the BP SEI message, and
an eighth syntax element indicating for the i-th sublayer for the VCL HRD, an offset to be used in the derivation of the DPB output time of the IRAP AU associated with the BP SEI message when the AU associated with the PT SEI message directly follows, in the decoding order, the IRAP AU associated with the BP SEI message.
