Abstract

PURPOSE: To make it possible to receive even low-speed information signals inputted from a tape recorder and a telephone line, etc., by using the information processing circuit of a unit, which receives information signals which are multiplexed into TV signals and are transmitted, as it is.
CONSTITUTION: In case that information signals consisting of control signals and character code signals are multiplexed to TV signals are tranmitted, they are superposed in an arbitrary, for example, 20th horizontal scanning time during a vertical fly-back period with a data rate of approximately 5-6M Hz and are transmitted. Video detector circuit 1, gate pulse generation circuit 5 which becomes high-level only in the 20th horizontal scanning time, display cathode-ray tube 15 and information processing circuit 6 are incorporated in TV receiver 16. Meanwhile, signals of low-speed information signal source 17 such as a tape recorder and a telephone line connecting acoustic coupler are converted up to high-speed information signals with the same data rate as TV multiplex information signals in input interface circuit 18. Then, TV multiplex information signals and converted information signals are switched by 19 and are supplied selectively and processed in circuit 6.
