Abstract

An information processing device includes an extraction section for extracting, from program information, a genre feature word that is a keyword representing a genre feature. An identification section identifies a channel by genre based on the genre feature word extracted from the program information associated with a program to be broadcast on the channel. The processing device further includes a display processing section for providing control over the channel to be displayed after genre classification.

First claim

What is claimed is:

1. An information processing device, comprising:
a genre word table having a plurality of genres and a plurality of genre feature words indicating features of the plurality of genres, wherein each genre is associated with a predetermined group of genre feature words; and
one or more processor configured to
extract genre feature words from program information of a plurality of programs included in a predetermined broadcast period of a channel, and classifying the extracted genre feature words based on programs and genres, the genre feature words being extracted at least from a program title, the name of a channel, and a program summary included in the program information of programs on channels available for selection during a predetermined time period;
identify the channel by genre based on the genre feature words extracted from the program information;
acquire a command from a remote controller that indicates an operation of a program by a user;
assign a value to a respective genre feature word based on an operation history of a program whose program information is used to extract that respective genre feature word and calculating a total value of all genre feature words extracted from a respective channel as a user's degree of preference of the respective channel,
wherein the operation history of a program includes displaying, recording, dubbing and erasing of the program, and a higher value is assigned to a genre feature word extracted from a displayed program than an erased program;
the one or more processors being further configured to display channels corresponding to the plurality of genres.

2. The information processing device according to claim 1 , wherein the one or more processors are configured to identify the channel by genre based on a counting result of the extracted genre feature word for each of a plurality of genres.

3. The information processing device according to claim 1 , wherein the one or more processors are configured to identify the program by genre based on the genre feature word extracted from the program information for the program, and based on the genre of the program to be broadcast on the channel, identifies the channel by genre.

4. The information processing device according to claim 3 , wherein the one or more processors are configured to identify the channel by genre based on a counting result of the program to be broadcast on the channel for each of a plurality of genres.

5. The information processing device according to claim 3 , wherein the one or more processors are configured to identify the channel by genre based on a counting result of a broadcast time of the program to be broadcast on the channel for each of a plurality of genres.

6. The information processing device according to claim 1 , wherein the one or more processors are configured to identify the channel by genre on a basis of the program based on the extracted genre feature word, and the display control means exercises control over the channel to be displayed after classification of a program currently being on the air into any of the genres.

7. The information processing device according to claim 1 , wherein the one or more processors are configured to display a genre list, and exercises control over the channel to be displayed in a list for any one of a plurality of genres selected from the genre list.

8. The information processing device according to claim 1 , wherein the one or more processors are configured to exercise control over the channel, when the degree of preference is high, to be displayed as a channel belonging to a group different from a plurality of genres.

9. An information processing method, comprising:
providing a genre word table having a plurality of genres and a plurality of genre feature words indicating features of the plurality of genres, wherein each genre is associated with a predetermined group of genre feature words;
extracting genre feature words from program information of a plurality of programs included in a predetermined broadcast period of a channel, and classifying the extracted genre feature words based on programs and genres;
identifying the channel by genre based on the genre feature words extracted from the program information;
acquiring a command from a remote controller that indicates an operation of a program by a user;
assigning a value to a respective genre feature word based on an operation history of a program whose program information is used to extract that respective genre feature word and calculating a total value of all genre feature words extracted from a respective channel as a user's degree of preference of the respective channel,
wherein the operation history of a program includes displaying, recording, dubbing and erasing of the program, and the calculating step assigns a higher value to a genre feature word extracted from a displayed program than an erased program; and
displaying channels corresponding to the plurality of genres,
wherein the extracting step extracts genre feature words at least from a program title, the name of a channel, and a program summary included in the program information of every program available for selection during a predetermined time period.

10. A non-transitory computer readable medium having recorded thereon a program operable to instruct a computer to execute a process, comprising
providing a genre word table having a plurality of genres and a plurality of genre feature words indicating features of the plurality of genres, wherein each genre is associated with a predetermined group of genre feature words;
extracting genre feature words from program information of a plurality of programs included in a predetermined broadcast period of a channel, and classifying the extracted genre feature words based on programs and genres;
identifying the channel by genre based on the genre feature words extracted from the program information;
acquiring a command from a remote controller that indicates an operation of a program by a user;
assigning a value to a respective genre feature word based on an operation history of a program whose program information is used to extract that respective genre feature word and calculating a total value of all genre feature words extracted from a respective channel as a user's degree of preference of that respective channel,
wherein the operation history of a program includes displaying, recording, dubbing and erasing of the program, and the calculating step assigns a higher value to a genre feature word extracted from a displayed program than an erased program; and
displaying channels corresponding to the plurality of genres,
wherein the extracting step extracts genre feature words at least from a program title, the name of a channel, and a program summary included in the program information of every program available for selection during a predetermined time period.

11. An information processing device, comprising:
a genre word table having a plurality of genres and a plurality of genre feature words indicating features of the plurality of genres, wherein each genre is associated with a predetermined group of genre feature words;
an extraction unit that extracts genre feature words from program information of a plurality of programs included in a predetermined broadcast period of a channel, and classifies the extracted genre feature words based on programs and genres;
an identification unit that identifies the channel by genre based on the genre feature words extracted from the program information;
a command acquiring unit that acquires a command from a remote controller that indicates an operation of a program by a user;
a calculation un
