    摘要: A control information generating apparatus is provided which is used in broadcast systems designed to transmit audio and video signals and/or teletext signals together with video control information and program information in multiplexed form. The control information generating apparatus transmits EPG (Electronic Program Guide) information (i.e., control information) for transmission of the audio and video signals and includes a control information generating circuit and a control information outputting circuit. The control information generating circuit receives program schedule information on a program from a broadcast database to generate and output control information. The control information outputting circuit receives and output the control information to a multiplexer in which the control information and a data signal from an audio/video data transmitter are multiplexed and transmitted on a carrier wave.
