Disclosed is a cable television system including a broadcasting center and terminal devices. When a notification data is to be transmitted to each terminal device, the broadcasting center transmits a channel data indicating a channel through which the notification data is transmitted. The terminal device, upon receipt of the channel data, stores the channel data in a memory. When the terminal device is turned OFF, the last viewed channel number is stored in the memory. When, the terminal device is turned ON, if the channel data transmitted from the broadcasting center is stored in the memory, the terminal device is tuned in the channel indicated by the channel data, while if the channel data is not stored in the memory, the terminal device is tuned in the last viewed channel.
