全番組データをメモリ(9)にストアして行く。A signal from the remote controller (19) is received by the light receiving section (20), and the signal is sent to the remote controller, CPU (14) or image processing CP.
A control signal from U (6) causes the switching circuit (5) to select the tuner of a specific channel, for example, the first tuner (2).
Select a). Then, the TV video signal input from the antenna (1) selects lch with the first tuner (2a), extracts the teletext signal with the extraction circuit (3a), and converts it into a digital signal, and stores it in the program memory. (4a)
Program data per IVd is stored in memory. Before the next Vd period begins, the program data stored in the program memory (4a) is sequentially transferred and stored in the teletext signal to the memory (9) by the image processing CPU (6). The above operations are performed in Vd cycles, and when the lch portion is completed, use the remote control (19) to switch to other channels (2b)...
2n) and store all program data of all teletext channels in the memory (9) in the same way.
