[0012] Reference numeral 12 is a program for correcting the registered program reservation information to make the program match if the contents such as the start time and the end time are not matched even though they are the same program as a result of the collation. It is a reservation information correction means.

[0013]

In FIG. 1, when making a video recording reservation, the user activates the program reservation information registration means 9 of the receiving terminal 2 to register the program reservation code of a desired program. After that, the user does not need to perform any operation regarding the video recording reservation.

The broadcasting station 1 transmits a program organization program for a broadcasting program of its own station by teletext on a predetermined normal or dedicated channel. If you do not use a dedicated channel for teletext of the programming program, add information that can be easily identified from other teletext programs, or set the broadcasting time of the programming program to a specific time, Make it easy to identify on the receiving terminal side. However, when the dedicated channel is used, the program composition program is in a state of being constantly broadcast.

The television broadcast receiving section 5 of the receiving terminal is controlled to select the designated channel when the recording reservation is executed. The teletext receiving unit 6 is controlled to the channel of the teletext program of the broadcasting station of the reservation target channel (the channel on which the program organization program is broadcast).

The program reservation code detecting means 10 sequentially extracts the program reservation code from the received data every time the teletext receiving unit 6 receives a teletext of a program organization program.
The program reservation information collating means 11 collates each retrieved program reservation code with already registered program reservation information having the same program number. If a mismatch is detected in the collation, the program reservation information correction means 12 causes
The registered program reservation information is corrected according to the program reservation code in the program scheduling program that does not match.

Since these correction operations are automatically performed without user intervention, as long as there is a change in the programming program from the broadcasting station and it is detected before the reserved time, the program reservation information is Corrected automatically.
