ets of coded video sequences (including the complete coded video sequences) conforming one or more of the profiles specified in Annex G. In Annex C it is specified which of the HRD parameter sets specified in the SVC VUI parameters extension are used for conformance checking. Rec. ITU-T H.264 (01/2012) vui_ext_num_entries_minus1 plus 1 specifies the number of information entries that are present in the SVC VUI parameters extension syntax structure. The value of vui_ext_num_entries_minus1 shall be in the range of 0 to 1023, inclusive. Each information entry is associated with particular values of temporal_id, dependency_id and quality_: and may indicate timing information, NAL HRD parameters, VCL HRD parameters, and the presence of picture structure information for a particular subset of coded video sequences as specified in the following. vui_ext_dependency_id[ and vui_ext_quality_id[i] indicate the maximum value of DQId for the i-th subset of coded video sequences. The maximum value of DQId for the i-th subset of coded video sequences is derived by vui_ext_dependency_id[i]+(vui_ext_quality_id[i]<<4). vui_ext_temporal_id[ ] indicates the maximum value of temporal_io for the i-th subset of coded video sequences. The SVC VUI parameters extension syntax structure shall not contain two or more information entries with identical values ofvui_ext_dependency_id[i],vui_ext_quality_id[i],a and vui_ext_temporal_id[i]. The following syntax elements apply to the coded video sequences that are obtained by the invoking the sub-bitstream extraction process as specified in clause G.8.8.1 with tIdTarget equal to vui_ext_temporal_id[i], dId7 Target equal to yui_ext_dependency_id[ and qIdTarget equal to vui_ext_quality_id[i] as the inputs and the i-th subset of coded video sequences as the output. vui_ext_timing_info_present_flag[ i equal to 1 specifies thatvui_ext_num_units_in_tick[i],vui_ext_time_scale[i], and vui_ext_fixed_frame_rate_flag[i i] for the i-th subset of coded video sequences are present in the SVC VUI parameters ext
