Abstract

PURPOSE:To display effectively the selection state of a designated program, by displaying the number identification mark of the designated program on a display screen and making the display mode different in the case, where the designated program is included in a transmitting character broadcast program, and the case where it is not included. CONSTITUTION:A character broadcasting signal inserted in the vertical blanking time of a video signal is separated in a character broadcasting signal separating and clock regenerating part 10 and is supplied to a character broadcasting signal processing part 11. The signal processing part 11 outputs pattern and color data (c) and a display mode indication output and supplies them to a digital memory 12 and a memory controlling part 13 respectively. When a program to be received is designated in a program designating part 15, the program selection output is supplied from a program selecting part 16 to a program identification mark display part 18 and the program code of the designated program is compared with program codes in a program index packet; and if a program code coincident with the program code of the designated program is obtained, the display mode of the program identification mark on the display screen is changed.
