PURPOSE:To pick up a desired program, by picking up a character every program and comparing this with the charactor of a received brodcast wave. CONSTITUTION:A viewer designates a desired program with the instruction of the retrieved program by depressing a specified key on a keybford 53 to a microcomputer 20 simultaneously with the instructon of the program retrieval, a channel selection voltage corresponding to each channel is sequentially obtained from a channel selection scanning circuit 40 and a digital data being the information indicating the level of sound of program of the specified channel is obtained. When this digital data coincides with the characteristic data of the program designated from a RAM22, the channel selection voltage of a channel selection scanning circuit 40 spots at the channel in coincidence. |
