You may be on to something here. I don't know how the v-chip
works. Some research may be of value along this line as it
detects the TV Rating somehow. Is data sent during the
blanking interval that is used by the v-chip or does it
examine the video stream? Since advertisers always want
their stuff to be shown is there some special code that is
detected by the v-chip at the start of commercials? In the
US the FCC mandates the v-chip and requires all providers,
OTA and Cable, to transmit whatever the v-chip uses to
detect the rating for all shows.
I have seen some movie trailers shown as commercials that
contain a rating for the trailer.
