Definitions
- the present invention relates to a technique for searching for and extracting information representing a program broadcast from an electronic program guide.
- Keyword search is a search technique that has been used in the past! This keyword search is very convenient when searching ordinary database power data. Normally, when searching a database, a user can obtain desired data by performing a keyword search using universal keywords.
- the above-described technique is used when searching for a TV program from an electronic program guide.
- TV programs examples include special programs and broadcast programs that are regularly broadcast (periodic programs).
- searching for a program name that includes the keyword “news” results in a “big news compilation” that summarizes the large ones of youth over the past year. This is the case when a TV program (an example of a regular program) with a program name of “12 o'clock-youth” broadcasted at a fixed time every day can be obtained.
- an object of the present invention is to provide a program search device, a search method, and a search program that search for a program by keyword search and handle the searched program by distinguishing between a special program and a regular program. .
- the present invention is an electronic program guide that searches for a program corresponding to the current electronic program guide power and includes at least one program display information representing a broadcast program.
- Program table storage means for storing, extracted keywords and corresponding effective period
- keyword storage means for storing, time acquisition means for acquiring the current time, and effective including the acquired current time
- An extracted keyword corresponding to a period is read from the keyword storage means
- program display information including the extracted extracted keyword is detected from the electronic program table, and detecting means detects at least one detected by the detecting means.
- program display information indicating a regular program is extracted as regular program display information
- program display information indicating a program different from the regular program is extracted as special program display information. Characterized in that it comprises a Extraction means that.
- the program search device also reads the extracted keyword corresponding to the effective period including the current time by using the keyword storage means, and uses the read extracted keyword to obtain program display information from the electronic program guide. Since one or more are detected and the regular program display information and the special program display information are extracted from the detected one or more program display information, the special program and the regular program can be handled separately. In addition, since the desire to distinguish between special programs and regular programs tends to concentrate on a specific period, more precise extraction is possible by using extracted keywords with valid periods.
- the program search device may further include an excluding unit that excludes the regular program display information extracted by the extracting unit.
- the program search device since the program search device excludes the extracted regular program display information, only one or more special program display information can be acquired.

- the program search device can extract the regular program display information using the regular program name.
- the program search device can extract special program display information from an electronic program guide including at least one program display information representing a program broadcast in one cycle. This is because a program that is broadcast regularly during one cycle is broadcast once, and one program display information representing the program is extracted. This is because program display information representing the program can be extracted as regular program display information by using the program name.
- the program search device further includes program name storage means for storing a recording reservation program name for which a recording reservation has been made by a user, and the extraction means further includes the detection.
- the program display information representing the program indicated by the recording reserved program name stored in the program name storage means is retrieved from the one or more program display information detected by the means, and the program display obtained by the search is retrieved.
- the information may be acquired as reserved program display information, and the exclusion unit may further exclude program display information representing a program indicated by the reserved program display information acquired by the extraction unit. .
- the program search device acquires reserved program display information from one or more program display information detected by the detection means using the recording reserved program name, and acquires the reserved reservation Program display information can be excluded.
- the program extracting apparatus can exclude program display information representing a program reserved for recording.
- the extracting means uses the program display information representing a program broadcast regularly among the extracted one or more program display information as the regular program display information, and the remaining one or more program display information as the special program display information.
- the program search device further includes display means for distinguishing and displaying the display mode of the one or more special program display information extracted by the extraction unit and the display mode of the regular program display information.

At this time, the search control unit 111 deletes the contents of the work table T161 and stores the program display information that is not the display target in the non-target program storage area. Also erase the contents.
- the search control unit 111 first has the same program display information among the one or more program display information stored in the work table T161 based on the first exclusion condition "duplication". In order to determine whether to do so, a complete match search of the program display information is performed (step S150). The search control unit 111 changes the exclusion flag corresponding to the program display information detected by the exact match search to “1” (step S 155).
- the search control unit 111 determines whether or not the program display information including the form information "Re" exists in the work table T161, that is, whether or not the rebroadcast program name exists in the work table T161. (Step S160) If it is determined that it exists (“Y ESj” in Step S160), all rebroadcast program names stored in the work table T161 are acquired (Step S165).
