Ancillary data packets send ancillary packets between MegaCore functions. Ancillary
data packets are typically placed between a control data packet and a video data
packet and contain information that describes the video data packet, for example
active format description codes.
An ancillary data packet can contain one or more ancillary packets, each ancillary
packet starts with the code 0, 3FF, 3FF.
