How is the correct splice point identified in the splice command?
The command contains a splice_time field. For the execute command the splice_time value must be given in the 90 khz clock ticks. For an Out Point, the splice_time value is set to be the same as the value in the DTS_next_AU field of the Out Point Packet of the PCR_PID. For an In Point, the splice_time value is set to be the same as the value in the DTS_next_AU field of the In Point Packet. The splice_time value may be optionally given as a SMPTE time code in addition to the DTS value. For the schedule command, time code alone may be used.
