Recording control apparatus and method, and program

A recording control method for controlling the recording of content of a broadcast program, comprising the steps implemented by a computer of:

• acquiring electronic program guide data concerning the broadcast program, the electronic program guide data indicating a program guide title of the broadcast program;
• detecting a recorded title of the broadcast program from reserve-recording data indicating a recording reservation of the broadcast program;
• calculating, within a predetermined number of days before the broadcast program is broadcast, and, within each day of the predetermined number of day for a time period, a similarity between the recorded title of the broadcast program and the program guide title of the broadcast program, wherein:
• the similarity is calculated by comparing characters or syllables comprising individual parts of words included in the recorded title and the program guide title, and
• the time period starts at a first predetermined time before a time that the broadcast program is scheduled to start, and the time period ends at a second predetermined time after a time that the broadcast program is scheduled to end;
• determining whether the broadcast time of the broadcast program has changed based on the calculated similarity;
• and
• changing the reserve recording data to reflect the change to the broadcast time.

A non-transitory, computer-readable storage medium storing a program that, when executed by a processor of a computer, causes the computer to perform a method for controlling the recording of content of a broadcast program, the method comprising:

• acquiring electronic program guide data concerning the broadcast program, the electronic program guide data indicating a program guide title of the broadcast program;
• detecting a recorded title of the broadcast program from reserve-recording data indicating a recording reservation of the broadcast program;
• calculating, within a predetermined number of days before the broadcast program broadcast, and, within each day of the predetermined number of days, for a time period, a similarity between the recorded title of the broadcast program and the program guide title of the broadcast program, wherein:
• the similarity is calculated by comparing characters or syllables comprising individual parts of words included in the recorded title and the program guide title, and
• the time period starts at a first redetermined time before a time that the broadcast program is scheduled to start, and the time period ends at a second predetermined time after a time that the broadcast program is scheduled to end;
• determining whether the broadcast time of the broadcast program has changed based on the calculated similarity;
• and
• changing the reserve recording data to reflect the change to the broadcast time.

A recording control apparatus for controlling the recording of content of a broadcast program, comprising:

• an acquisition unit configured to acquire electronic program guide data concerning the broadcast program, the electronic program guide data indicating a program guide title of the broadcast program;
• a detector configured to detect a recorded title of the broadcast program from reserve-recording data indicating a recording reservation of the broadcast program;
• a calculator configured to calculate, within a predetermined number of days before the broadcast program is broadcast, and, within each day of the predetermined number of days, for a time period, a similarity between the recorded title of the broadcast program and the program guide title of the broadcast program, wherein:
• the similarity is calculated by comparing characters or syllables comprising individual parts of words included in the recorded title and the program guide title, and
• the time period starts first predetermined time before a time that the broadcast program is scheduled to start, and the time period ends at a second predetermined time after a time that the broadcast program is scheduled to end;
• and
• a changing unit configured to determine whether the broadcast time of the broadcast program has changed based on the similarity calculated by the calculator, and change the reserve recording data to reflect the change to the broadcast time.
