Abstract

A recording apparatus is disclosed which records at least either a video or an audio signal of a broadcast program in accordance with reservation information. The recording apparatus includes: an acquisition block configured to acquire program information about the broadcast program; a calculation block configured to calculate a degree of similarity between a program name included in the reservation information and the program name described in the program information acquired by the acquisition block; a changing block configured to change the reservation information using the program information about the broadcast program determined by the degree of similarity, the changing block further changing the reservation information based on the program information about the broadcast program corresponding to program identification information included in the reservation information; and a recording control block configured to record at least either the video or the audio signal of the broadcast program in accordance with the reservation information.

Claims

1. A recording apparatus for recording at least either a video or an audio signal of a program in accordance with reservation information, said recording apparatus comprising:

an acquisition block configured to acquire program information about said program;

a calculation block configured to calculate a degree of similarity between a program name included in said reservation information and the program name described in said program information acquired by said acquisition block;

a changing block configured to change said reservation information using said program information about the program determined by said degree of similarity, said changing block further changing said reservation information based on the program information about the program corresponding to program identification information included in said reservation information; and

a recording control block configured to record at least either the video or the audio signal of said program in accordance with said reservation information.

2. The recording apparatus according to claim 1, wherein, while recording is in progress in accordance with said reservation information, said recording control block compares the program identification information included in said reservation information with the program identification information about the currently broadcast program, said recording control block further stopping temporarily, resuming, or terminating the ongoing recording depending on an outcome of the comparison.

3. The recording apparatus according to claim 1, wherein said changing block updates said reservation information at predetermined time intervals.

4. A recording method for use with a recording apparatus which records at least either a video or an audio signal of a program in accordance with reservation information, said recording method comprising the steps of:

acquiring program information about said program;

calculating a degree of similarity between a program name included in said reservation information and the program name described in said program information acquired by said acquisition block;

changing said reservation information using said program information about the program determined by said degree of similarity, said changing step further changing said reservation information based on the program information about the program corresponding to program identification information included in said reservation information; and

recording at least either the video or the audio signal of said program in accordance with said reservation information.

5. A program for causing a computer to carry out a procedure for recording at least either a video or an audio signal of a broadcast program in accordance with reservation information, said procedure comprising the steps of:

acquiring program information about said program;

calculating a degree of similarity between a program name included in said reservation information and the program name described in said program information acquired by said acquisition block;

changing said reservation information using said program information about the program determined by said degree of similarity, said changing step further changing said reservation information based on the program information about the program corresponding to program identification information included in said reservation information; and

recording at least either the video or the audio signal of said program in accordance with said reservation information.
