Abstract

PURPOSE:To realize a plural-channel reservation function and an instantaneous selecting function by simultaneously receiving and storing teletext signals from a tuner device and the other device. CONSTITUTION:A switching circuit 35 is switched to a terminal (a) side, an instruction is issued to a memory device 31 by a read signal 33, and a teletext signal 14 is read and processed. Next, the circuit 35 is switched to a terminal (b) side, and a teletext signal 16 of a memory device 32 is read by a read signal 34. Since the teletext signal is superimposed only on a certain special period in the vertical blanking interval of a television signal, the signal in the signal vertical blanking interval of a signal teletext signal is processed in the time of 1/2 fields. By repeating the above processings, the signals 14 and 16 can be simultaneously received. In addition, by storing the teletext program a of the all channels other than the receiving channel into the memory device, the instantaneous selecting function, which can select the programs without a wait time even immediately after the switching of the channel, can be realized.
