Abstract

Station selection history information is stored in a flash memory for each predetermined time (for example, 5 minutes) in the past from a predetermined number of days ago to the current time. In response to a station selection instruction, a CPU calculates a corrected time by rounding the current time to a time at which the station selection history information is to be stored next. If the station selection history information on a past (for example, a day ago, a week ago) at a time corresponding to the corrected time is stored in the flash memory, the CPU selects a broadcast station included in the stored station selection history information.

Claims

1. A receiving device comprising:

receiving means for receiving a broadcast;

operation means for performing a station selection instruction operation;

storage means for sequentially storing station selection history information including at least a selected broadcast station for each unit time; and

control means for, when station selection history information in a past at a time corresponding to a corrected time is stored in said storage means, selecting a broadcast station included in the stored station selection history information, said corrected time being generated by rounding a current time to a next multiple of the unit time.

2. The receiving device according to claim 1, further comprising acquisition means for acquiring an Electronic Program Guide that includes broadcast stations, program start/end dates and times, and program names of programs that are broadcast,

wherein, if the station selection history information in a past at a time corresponding to a corrected time is stored in said storage means, said control means further checks if program information, composed of the same broadcast station and the same program name as a broadcast station and a program name stored in the station selection history information, is included in the Electronic Program Guide as program information at the corrected time of today and, if such program information is included, selects the broadcast station stored in the stored station selection history information.

3. A receiving station comprising:

receiving means for receiving a broadcast;

acquisition means for acquiring an Electronic Program Guide that includes broadcast stations, program start/end dates and times, and program names of programs that are broadcast;

operation means for performing a station selection instruction operation;

storage means for sequentially storing watching history information including at least a selected broadcast station, a program name, a watching start date and time, and a watching time for each unit time; and

control means that acquires program information on all broadcast stations broadcast at a time corresponding to a corrected time, generated by rounding a current time to a next multiple of the unit time, from the Electronic Program Guide and at the same time extracts programs, watched for a time equal to or longer than a predetermined watching time, from station selection history information in a past stored in said storage means, compares the program information on all broadcast stations broadcast at the time corresponding to the corrected time with the programs watched for a time equal to or longer than the predetermined watching time, and, if there is one matching program, selects a broadcast station of the matching program and, if there are a plurality of matching programs, selects a broadcast station of one program from the plurality of matching programs.

4. The receiving device according to claim 3

wherein, if there are the plurality of matching programs as a result of the comparison between the program information on all broadcast stations broadcast at a time corresponding to the corrected time and the programs watched for a time equal or longer than the predetermined watching time, said control means selects a broadcast station of a program watched first after the current time from the plurality of matching programs.

5. The receiving device according to claim 3

wherein, if there are the plurality of matching programs as a result of the comparison between the program information on all broadcast stations broadcast at a time corresponding to the corrected time and the programs watched for a time equal or longer than the predetermined watching time, said control means selects a broadcast station of a program started first from the plurality of matching programs.

6. The receiving device according to claim 3

wherein, if there are the plurality of matching programs as a result of the comparison between the program information on all broadcast stations broadcast at a time corresponding to the corrected time and the programs watched for a time equal or longer than the predetermined watching time, said control means selects a broadcast station of a program watched for a longest time from the plurality of matching programs.

7. A receiving method comprising the steps of:

sequentially storing station selection history information including at least a selected broadcast station for each unit time;

calculating a corrected time in response to an automatic station selection instruction from a user, said corrected time being generated by rounding a current time to a next multiple of the unit time; and

checking if the station selection history information in a past at a time corresponding to the corrected time is stored and, if such information is stored, selecting a broadcast station included in the stored station selection history information.
