icture scan Value Original picture scan progressive interlaced unknown reserved nuit_field_based_flag is used in calculating clockTimestamp, as specified in Equation D-1. counting_type specifies the method of dropping values of the n_frames as specified in Table D-3. Rec. ITU-T H.264 (01/2012) Table D-3 - Definition of counting values Value Interpretation no dropping of n frames count values and no use of time offset no dropping of n frames count values dropping of individual zero values of n frames count dropping of individual MaxFPS - 1 values of n frames count dropping of the two lowest (value 0 and 1) n frames counts when seconds_value is equal to 0 and minutes value is not an integer multiple of 10 dropping of unspecified individual n frames count values dropping of unspecified numbers of unspecified n frames count values 7..31 reserved full_timestamp_flag equal to 1 specifies that the n frames syntax element is followed by seconds_value, minutes_value, and hours_value. full_timestamp_flag equal to 0 specifies that the frames syntax element is followed by seconds_flag. discontinuity_fla equal to 0 indicates that the difference between the current value of clockTimestamp and the value of clockTimestamp computed from the previous clock timestamp in output order can be interpreted as the time difference between the times of origin or capture of the associated frames or fields. discontinuity_flag equal to 1 indicates that the difference between the current value of clockTimestamp and the value of clockTimestamp computed from the previous clock timestamp in output order should not be interpreted as the time difference between the times of origin or capture of the associated frames or fields. When discontinuity_flag is equal to 0, the value of clockTimestamp shall be greater than or equal to all values of clock Timestamp present for the preceding picture in DPB output order. cnt_dropped_flag specifies the skipping of one or more values of n frames using the counting method specified by counting_type. n_frames spec
