Abstract

PURPOSE:To confirm a broadcasting system and channel at the same time by providing a broadcasting system discriminating section and displaying video signals produced by synthesizing the output of the broadcasting system discriminating section and channel information being received on a display section. CONSTITUTION:When a request for switching channels or displaying the number of a channel being received on the screen of a CRT 8 is outputted to a microcomputer 5 constituting a broadcasting system displaying means during the reproduction of a telecasting program on the screen of the CRT 8, the means 5 inputs the broadcasting system being received from a broadcasting system discrimination circuit 4. Then a colored signal indicating the number of a channel being received is outputted from a red, green, and blue character display drive circuits 5-R, 5-G, and 5-B in accordance with the relation between broadcasting systems and colored signals preset by means of a broadcasting system discriminated input processing circuit 5-A and signals from a video detection circuit 3, video signal switching signal, and signals synthesized by means of an amplifier circuit 6 are inputted as video signals to the CRT 8 through a CRT drive circuit 7. Thus the number of a channel and the broadcasting system being received are simultaneously projected on the screen.
