Abstract

PROBLEM TO BE SOLVED: To store program video recording reservation data to a storage device without the presence of a cassette tape. SOLUTION: A user mounts an IC card 1 to an IC card slot 72. When the user depresses an EPG button of a remote commander, a television receiver 71 receives an EPG via an antenna and a tuner and displays it on a screen. The user selects a program whose video recording is reserved from the EPG displayed on the screen and depresses an enter button of the remote commander. A microcomputer built in the television receiver 71 stores selected video recording reservation data in an EEPROM of the IC card 1, via a reader/writer built in the television receiver 71.

In step S12, the reader / writer 3
The first microcomputer 46 determines whether or not all the recording reservation data (program data) has been read. If it is determined that all the recording reservation data has not been read yet, the process returns to step S11, and the processes after step S11 are repeatedly executed. On the other hand, if it is determined that all the recording reservation data has been read, the process proceeds to step S13.

In step S13, it is determined whether or not the read recording reservation data is valid. For example, in the read recording reservation data, it is determined whether the broadcast start time of the program reserved for recording is a predetermined time after the current time, or It is determined whether or not it is a predetermined time within. If it is determined that the recording reservation data is valid, the process proceeds to step S14, where the read recording reservation data is converted into recording reservation data for processing by the microcomputer (not shown) of the VTR 81. On the other hand, step S
If it is determined in step 13 that the recording reservation data is not valid, the process ends.

As described above, the recording reservation is made in accordance with the recording reservation data pre-recorded on the IC card 1 of the cassette 61. For example, when recording a program broadcast every week at a predetermined time, Can set a weekly recording of the program only by setting the cassette 61 on which the IC card 1 storing the recording reservation data of the program is stored in the VTR 81.

The data structure of the IC card in the present embodiment is an example, and the present invention is not limited to this.
