Abstract
Index values are periodically incremented at a central or primary video production control system and a video production control system node. Messages that include or otherwise indicate current index values generated by the primary video production control system are transmitted to the video production control system node, and the node reflects the messages back to the primary video production control system. The primary video production control system determines a round-trip message time, associated with the video production control system node, based on the transmitted messages and reflections of the messages received from the node. A further message that includes or otherwise indicates an instruction for execution of a task at a target execution time, is transmitted by the primary video production control system to the node at a time, in advance of the target execution time, that is based on the round-trip message time.
