Abstract
A program distribution system is disclosed for the simultaneous release of a program at a plurality of locations. The locations may include local broadcasters, or even individual devices. A program is modified so that it cannot be played without a release control signal and is then copied and distributed .either fixed in a media or electronically, i.e. via private network, the Internet, etc.) At the receiver the receiver first detects the release control signal and then replays the program at will. The program may include a time stamp in which case the receiver cannot replay the program until a control indicative of a current time/date corresponding to the date stamp. Alternative the program can be encrypted in which case the release control signal includes the decryption key. The release control can be broadcast over a tv channel, a radio channel and so on and is preferably imbedded into the signals of the standard tv or radio signals.
