DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program guide display device for displaying a program guide on a screen, and more particularly to a program guide display device capable of searching for a character string such as a program title and a performer name. .

[0002]

2. Description of the Related Art Along with the fact that more information can be transmitted by digital broadcasting, the number of channels of a program has been increased and an electronic program guide (EPG: Electroni)
c Program Guide) is increasing. Program information of a general electronic program guide is sent together with a broadcast program from a cable television broadcast station via a line or from a broadcast satellite via a radio wave. The receiver receives the program information, stores the program information in the storage device, and displays the program information on the display device when all the information on the program for a certain period is received. Alternatively, program information can be obtained from a network such as the Internet, or a CD-ROM
It may be obtained from such a medium. In such an electronic program guide, by assigning in advance the category to which the program belongs to each program,
Only programs belonging to the category desired by the user can be searched and displayed. As described above, the electronic program guide is effective in improving the operability of the receiver in response to the increase in the number of programs due to the increase in the number of programs due to the increase in the number of channels.

[0003] Here, in the conventional program guide display device, as shown in, for example, Japanese Patent Application Laid-Open No. 7-184130, a program title, a performer's name, and the like are input as keywords, and program guide data is searched. Is displayed as a program guide so that information desired by the user can be provided in an easily understandable manner.

[0004]

However, in the above-mentioned conventional program guide display apparatus, the user must input a character string such as a program title or a performer name as a keyword. In the case of a database search system or the like implemented on a personal computer, a keyboard for character string input is attached, so you can use this to input data.
In the case of a program guide display device that displays a program guide on the display of a television receiver, it is not practical to use a keyboard for a personal computer, and a device with a limited number of input keys such as a remote controller is used. Character input becomes difficult. Therefore, a keyword list is displayed on a display, and the user has to select a keyword included in the list using a remote controller or the like having a cursor movement button.
For this purpose, it is conceivable to prepare a keyword list in advance and provide it together with the program information. However, the character string of the keyword is included in both the keyword list and the program information, thereby increasing the transmission capacity. Not so desirable. Therefore, it is conceivable to transmit only the program information and create a keyword list from the program information on the receiver side. This method can extract keywords to some extent by using morphological analysis technology used in Japanese document processing technology, but has many detection errors and lacks certainty. Further, the receiver requires a dictionary in which not only keywords but also various words are registered, which raises the problem of increasing the cost of the receiver.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and has an object to provide a program guide display system and a program guide display device which can surely create a keyword list used for keyword search. The purpose is to gain.

[0006]

In order to solve the above-mentioned problems, a program guide display system according to the present invention (claim 1) transmits program information relating to a broadcast-scheduled program from a broadcasting station, and receives the program information on a receiving side. In a program guide display system that creates and displays a program guide based on the information and searches and displays a program including a keyword selected from outside from the programs in the program guide, a character string of the program information is determined in advance. By assigning the given identifier, the character string to which the identifier is assigned is designated as a keyword and its kana, and the received kana is extracted together with the keyword from the received program information. A set of kana is accumulated, and an arbitrary keyword is selected using the accumulated reading kana.

A program table according to the present invention (claim 2)
The display device is inputted from the outside and relates to a program to be broadcast.
In addition, a program table is created and displayed based on program information including a keyword selected from the outside and a character string keyword to which an identifier designating the reading kana is added, and a program table is selected from the programs in the program table. A program table display device for searching for and displaying a program including the selected keyword, storing means for storing the program information, and keyword extracting means for extracting the keyword and the kana from the stored program information. And a keyword storage means for storing the extracted keywords and the kana of the keyword in combination, and a keyword table for creating a keyword table in which the keywords are described in alphabetical order in accordance with the kana from the stored keywords. Creation means, input means for obtaining an external input, and keyword information described in the keyword table. Searching means for extracting program information including a keyword selected from the outside in a character string from the program information stored in the storage means, and an identifier and a reading kana from a character string of the program information extracted by the searching means. Identifier deleting means for deleting the program information, program table generating means for generating a program table based on the program information from which the identifier and the kana have been deleted, a display for displaying the generated program table, and displaying the program table on the display. And an interface unit for displaying.

Next, the operation of the program guide display device configured as described above will be described with reference to FIGS. First,
VBI (Vertical Blanking In) of satellite broadcasting or terrestrial television is received by receiving means (not shown).
terval (vertical blanking period) is received to obtain a program guide file. The program guide file may be obtained using the Internet, or may be provided from a medium such as a CD-ROM.

Next, the program guide storage unit 101 inputs and stores the obtained program guide file. Next, the keyword extracting unit 103 searches for a character string of the program information 13 (FIG. 1) in the program guide file stored in the program guide storage unit 101, and according to the keyword type list (FIG. 5) stored in advance. , Keywords and pronunciations are extracted and described in a keyword file stored in a keyword file storage unit. More specifically, for example, the character string of the program information 13 shown in FIG.
>, The keyword “Week-end cinema” and the pronunciation pseudonym “Weekend cinema” of the character string surrounded by the identifier are extracted according to the keyword type list of FIG. Program title), and a keyword file corresponding to the type, T.P. The extracted keyword “Weekend Cinema” and the pronunciation kana “Walkendsima” are registered in the keyword field and the reading kana field in the keyword file “kwd” (FIG. 7A). In the same way, FIG.
The other keywords and pronunciations included in the character strings shown in (1) are extracted and registered in the keyword file (FIGS. 7 (b), (c), and (d)).

Then, the keyword extracting unit 103 performs the above-described registration processing for all the program guide files stored in the program guide storage unit 101, and completes the keyword files for all types of keywords.

Next, the keyword table creation unit 105 creates a keyword table screen as shown in FIG. 8 using the GUI 106 according to the contents of the keyword file in the keyword file storage unit 104. That is, in the keyword type display window 205, any one of the keyword types shown in FIG. 7 is displayed.
Is the default. Subsequently, among the keyword files in the keyword file storage unit 104, the respective keywords described in the keyword field of the keyword file of “performers” (P.kwd) are sorted in the order of the Japanese syllabary with respect to the reading kana, and the keyword window 2
07. In addition, the first of the reading kana of each keyword
The third character (hereinafter referred to as an index) is described in the index window 209 so as to be located to the left of each keyword. When the same index continues (for example, in the case of “U” shown in FIG. 8), the display of the index may be omitted below the second keyword as illustrated.

When the keyword is a foreign word or the like, alphabetic characters can be used as the reading kana. In this case, the reading kana may be sorted in alphabetical order and displayed as described above. Furthermore, hiragana, katakana, and alphabets may be mixed as the reading kana. The sort order can be, for example, the shift JIS kanji code order, but of course, it is also possible to sort in the order determined at the time of design or in any order set by the user.

When the keyword is a kana character or an alphabet character, the reading kana is blanked, and the keyword extraction unit 103 uses the character string of the keyword as it is as the character string of the reading kana and sets it in the keyword file. It may be. According to this, since it is not necessary to describe the reading kana, the data amount of the program guide file can be suppressed.

Next, when an input for operating the keyword scroll button 208 by the user using the input key group is provided on the input unit 107, the input content is displayed on the GUI 106.
Output to Next, the GUI 106 moves the keyword in the keyword window 207 upward or downward by one.

Output to For example, as shown in FIG.
1 is set to "March 20, 1998"
The program table files for all the broadcasting stations corresponding to the date are acquired from the program table storage unit 101, and the program information 13, header 11 and program identification code 12 of the acquired program table file are output.

Next, the identifier deleting unit 108 extracts a one-byte character “<” from the character string of the program information
One byte character, ",", a character string (reading kana) following this, one single byte character, and ">" following this are deleted, and only the character string other than the identifier is left. That is, if a program table is created as it is from the obtained contents of the program table file, the character string of the program information 13 of the program table file includes
Because the identifier is added, the character string is displayed as it is, making it very difficult to see.

Next, the program guide creation unit 109 inputs the character string of the program information 13 subjected to the identifier deletion processing from the identifier deletion unit 108, and transmits the program guide file header 11 and the program identification code 12 from the search unit 102. A program table image is created using information such as a program start date and a broadcast station name included in the obtained header 11 and a character string of the program information 13 and output to the GUI 106.

Next, in the GUI 106, a program guide image is input from the program guide creating unit 109, and displayed on the display 110 as a program guide column 202, and the user browses it. Now, the user inputs the keyword type scroll button 20 using the input key group to the input unit 107.
If there is an input to change to "moderator" by operating 6,
The input content is output to the GUI 106. Next, GU
I106 processes the input contents and generates a keyword table creation unit 1
Output to 05.

Next, the keyword table creating unit 105 stores the C.I. kwd is sorted in the Japanese alphabetical order,
It is displayed in the keyword window 207 using I106.

When the user operates the keyword scroll button 208 using the input key group to change the input to “Naoya Okawa”, the input unit 107 outputs the input to the GUI 106.

Here, the display 1 is operated by the following operations.
FIG. 9 shows an example of display at 10. In FIG. 9, reference numeral 302 denotes a program broadcast date and time, a start time, an end time, and a broadcast station name in the left half, and a keyword search result list as a program list showing program information in the right half. 30
Reference numeral 4 denotes a keyword search result scroll button for scrolling the display content of the keyword search result list according to the user's selection. Reference numeral 312 denotes a currently selected keyword, which is highlighted to distinguish it from a keyword that has not been selected. In addition,
When there are a plurality of search results, the program list is sequentially displayed in the vertical direction, and the search results are scroll-displayed by the user selecting the keyword search result scroll button 304.

Next, the GUI 106 processes the input content and outputs the processed content to the search unit 102. The display 110 displays the character string "Naoya Okawa" in FIG.
Is displayed in reverse video.

Next, the search unit 102 receives the output from the GUI 106, sequentially scans the program table file stored in the program table storage unit 101, and includes a character string of the keyword "Naoya Okawa" in the program information 13. The program 11 acquires the header 11, the program identification code 12, and the program information 13 relating to the program to be executed, and outputs the header 11 and the program identification code 12 to the program table creation unit 109 and the program information 13 to the identifier deletion unit 108. Thus, it is possible to display only the program including the keyword set as the selected keyword 312 in the keyword window 207 by the user.

Next, the identifier deleting unit 108 deletes the identifier from the character string in the program information unit 13 and outputs only the character string other than the identifier.

Next, the program guide creation unit 109 inputs the character string of the program information 13 subjected to the identifier deletion processing from the identifier deletion unit 108, and also inputs the program guide file header 11 and the program identification code 12 from the search unit 102. A keyword search result list image is created by using information such as a program start date and a broadcast station name included in the obtained header 11 and a character string of the program information 13 and the like.
Output to UI 106.

Next, the GUI 106 inputs a keyword search result list image from the program table creation unit 109 and displays it on the display 110 as a keyword search result list 302, which the user views. When a keyword is selected, a keyword search result is displayed. Therefore, a program table 202 in which each program is displayed two-dimensionally with the channel of the broadcasting station on the horizontal axis and the time on the vertical axis is displayed. do not do.

As described above, according to the program guide display system according to the embodiment of the present invention, the identifier is assigned to the character string of the program information for creating the program guide to be displayed. It is assumed that the character string is used as a keyword, and the receiving side extracts and stores the keyword from the program information and selects an arbitrary keyword from the keyword. Therefore, the keyword must be transmitted in a separate file. Since there is no transmission capacity, the transmission capacity can be suppressed. You can also extract keywords according to their identifiers,
An error in the extraction process can be prevented.

Also, since a plurality of types of identifiers are set according to a character string to be used as a keyword, and keywords extracted according to the type are classified and stored, the user can select a keyword to be selected. Searching becomes easier, and keyword selection can be performed more easily. In addition, since the identifier further specifies the pronunciation of the keyword, the keyword table can be displayed in a predetermined order according to the pronunciation, even if the keyword is a kanji or the like.

Further, according to the program guide display device in the embodiment of the present invention, the identifier is deleted from the character string of the program information relating to the program to be displayed as the program guide, and the program guide is displayed. Unnecessary identifiers for the user are not displayed on the program guide, and the program guide is easy to see.

Note that the program guide display device according to the embodiment of the present invention is provided with clock means to obtain the current date and time, thereby limiting the search range to the current date and time. It is also possible. Various search methods can be used, such as allowing the user to input a broadcast station and limiting the search range to the input broadcast station, but these are not excluded from the claims.

In the program guide display system according to the embodiment of the present invention, the program guide file is transmitted together with the broadcast program from a broadcasting station via a radio wave such as a terrestrial wave or a satellite or a cable line, and the program guide display is performed. Although it is assumed that the program guide display device uses the program guide file obtained from a network such as the Internet or a medium such as a CD-ROM, the same effect as in the above embodiment can be obtained.
