1. A broadcast program transmission control apparatus, comprising:
- a plurality of program generation devices each including respective device control means for each controlling the operation of its respective program generation device in real time;
scheduling data producing means for producing program scheduling signals representing a schedule of programs to be generated at predetermined future times by respective ones of said program generation devices;
each said respective device control means being operative to store corresponding ones of said program scheduling signals representing a corresponding schedule of programs to be generated by its respective program generation device;
means for loading each said device control means with said program scheduling signals from the scheduling data producing means representing the schedule of programs to be generated by its respective program generation device; and
switching means for switching the programs generated by said program generation devices to a master broadcast output.
