A man went to a TV station and bought one minute’s worth of advertising time. He handed a videocassette to the station manager and learned to the second exactly when his one-minute tape would be on the station. Just before the scheduled time, the man turned on his TV set, tuned in to the correct channel and waited. At exactly the time for ad, a test pattern came on. The sound, an intense pure tone, did not change for a full minute. The picture stayed the same too. Then the man, pleased, turned off his TV set. Explain.
