    Abstract: A CATV center facility transmits, together with the television signals of a plurality of programs, display control data indicating program names and selection numbers of the respective programs and channel data indicating the numbers of channels on which the respective programs are being broadcast or to be broadcast. A terminal apparatus detects the program names, selection numbers and channel numbers from the display control data and the channel data, and makes a TV receiver display the detected program names and selection numbers in an associated manner. While looking at a picture thus displayed, a user selects a desired program by pushing a corresponding numeral button of a remote controller or a keyboard. In response to the program selection by the user, the terminal apparatus is tuned to the channel of the selected program.
