PURPOSE: A device for automatically decoding canal signal is provided to perform decoding of canal signal only in a desired channel by setting and storing automatic decoding of canal signal by channel. CONSTITUTION: A device for automatically decoding canal signal includes first and second tuners(2,3) for outputting image and sound signals, first and second switches(40,50) for switching output signals of the tuners according to switching control signals, a canal decoder(5) for receiving output signal from the second switch, canal-decoding the output signal and transmitting whether or not there is canal signal input to a micro computer, a third switch(60) for switching the output signal of the first switch and canal decoding signal of the canal decoder according to the third switching control signal and transmitting the switched signals to a CRT, a fourth switch(70) for switching the output signal of the tuners and the canal decoding signal, a recoding part(7) for storing the output signal of the fourth switch, and a micro computer(8) for controlling the switching of the switches. |
