Abstract
PURPOSE:To improve the operability of a multiscreen display TV receiver by automatically switching channels by presetting a desired channel and the time when the channel is received. CONSTITUTION:Video chrominance-signal processing circuits 14A-14D process output signals from tuners 13A-13D to display TV signals, received by the tuners 13A-13D, on an image receiving tube. A switching data memory 31 store channel data for specifying the tuners 13A-13D inputted through operation on a keyboard 37 and time data for the reception of them in pairs, and the time data stored in the memory 31 and current-time data generated by a timer circuit 33 are compared mutually by a comparator 32. When the comparator 32 generates a coincident output, the specified tuner data and specified channel data stored in the memory 31 is read on the basis of the address of an address memory 35 and channels of the specified tuners 13A-13D are selected through a decoder 35 to display chrominance signal data from memory circuits 15A-16B.
