Accordingly, the real-time comparison unit 40 compares the real-time information provided by the real-time information providing unit 20 with the broadcast time control information data of various programs input from the program broadcasting time providing unit 30 and performs the corresponding real-time comparison. The broadcast program transmission signal is transmitted to the broadcast control signal generator 50. At this time, multi-channel control information data is sent as control information, which is output as an IBM PC standard bus signal as shown in FIG. Thus, in the control logic combination circuit 1 of the broadcast control signal generator 50, the computer data and the control bus (IBM PC standard bus) are referred to by referring to the time information of the broadcast control data input from the computer database. When a broadcast control signal is applied, a predetermined logical combination is performed to select a broadcast signal of a desired channel.
