Abstract
Abstract Based on in-band data transmitted from a center facility that include titles, start times, lengths and channel numbers of respective programs of linked channels, the titles and start times are displayed together with selection numbers on a TV receiver upon depression of a schedule switch by a user. While watching a displayed picture, the user selects one of the selection numbers. Data indicating the start time, length and channel of the selected program is stored in a timer reservation area of a memory. The selected program is automatically displayed based on the stored data.
