188.8.131.52. Commit Packets
The commit packet triggers an update to a new set of control values.
When an IP receives a commit packet, it changes to any new register values at the start of the next video frame. The commit register ensures that all register updates occur simultaneously, which avoids the IP only applying some of the updated register values for the next incoming frame.
Like register update packets, the protocol does not allow commit packets between the last line of a field and an end-of-field packet. They should be in between the end of field of a previous field and the image information packet of the next field.
Refer to Legal packet ordering rules and Packet ordering examples figures in Rules for Packets.
