A selective broadcast communication system including a transmitting station for broadcasting programs, each program being preceded by program and subscriber identifying codes and followed by a stop code, and a plurality of subscriber stations receiving the transmitted programs and codes, each of the subscriber stations being selectively operable to reproduce only those programs which were preselected by detecting the program and subscriber identifying codes and determining the coincidence thereof with the preselected program and with a subscriber module such that preselected programs may be recorded by authorized subscribers automatically.
