Abstract

PURPOSE:To select a desired program for a short time by selecting and displaying character multiplex broadcasting data corresponding to the preset program number or specifying the program by a program guide display device at the switching to a multiplex mode even if no program channel is specified. CONSTITUTION:An output of a channel selecting device 51 is applied to a multiplex broadcasting processing device 52 and a video signal processing device 53, the output of the devices 52 and 53 is sent to a composing circuit 33 and the output of the circuit 33 is supplied to a CRT 54. A preset switch 58 on a keyboard 40 presets the program No. of a program in each channel in respect to all the channels. When one of these channels is selected and preset to the video mode, character multiplex broadcasting data corresponding to the selected channel are sampled, stored in a picture memory and displayed in the CRT 54. Even if a program channel is not specified, the desired program can be selected immediately from a program guide at the time of switching to the multiplex mode.
