Abstract

PURPOSE:To enable the user to perform an automatic switching of the channels without any complicated operation by memorizing the history of the channels selected in the past by the user of the reception device. CONSTITUTION:Time detecting means 4 transmits the time signal showing the time at the several predetermined time to control means 3. Means 3 monitors the channel constant channel selection circuit 2 is selecting and then detects the channel which is selected in the longest time with every time band. The selected channel is memorized in memory means 5 at the end of the time band. At the same time, means 3 reads out the information of means 5 at the starting time of the time band, and transmits the channel signal to channel selection circuit 2 only in case the specified channel is memorized to secure switching of the channels. As a result, in case the manual channel selection switch is not operated, circuit 2 carries out the channel selection based on only the channel information memorized in means 5.
