BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus in which a teletext receiving apparatus and a large-capacity database apparatus are integrated, and more particularly to a multimedia-compatible personal computer.

[0002]

2. Description of the Related Art As teletext broadcasts such as televisions and FMs become widespread, it becomes possible to collect various information using received data. However, since the amount of data transmitted by teletext is enormous, it is a difficult task for a user to browse all of them and collect only necessary information.

As a method for solving the above-mentioned problem, there is a method for narrowing down information to be given to a user by using a keyword (for example, Japanese Patent Application Laid-Open No. 63-87887). In this technique,
Only a program including a keyword preset by the user is provided, and the amount of data browsed by the user is automatically reduced.

[0004]

The above-mentioned method has two inconveniences when collecting information using teletext.
First, based on the obtained teletext data, a CD-RO
When acquiring information stored in a large-capacity database such as M and collecting information in more detail, it is necessary to manually extract a keyword from a teletext screen and input the keyword to a database device. This operation reduces the efficiency of information collection. Further, if the set keyword is not included in the data expected by the user, complete information collection cannot be realized, and it is impossible to completely set the keyword so as not to do so.

[0005] It is an object of the present invention to support a user's information collection work by combining a teletext receiver and a database device, and to improve the integrity thereof.

[0006]

In order to achieve the above object, an information collection support apparatus according to the present invention comprises: a character signal demodulation device for demodulating a character multiplex modulation signal; A character encoding device that encodes and outputs a string, a database device that stores image, sound, or document data including a character string that is a keyword, and a character string that is output by the character encoding device Into a word string, and a keyword dividing device that is stored in the database device.
A keyword extracting device that extracts a character string serving as a keyword from the decomposed word strings based on data of a character string serving as a keyword, and character information output from a character signal demodulating device displayed on a screen display device. Against the key
Character string that is a keyword extracted by the word extraction device

And a data selection device for outputting .

[0007]

The user prepares in advance the database of the field for which information is to be collected in the database device. And, by indicating the character string that is displayed in a modified manner in the data of the teletext displayed on the image display device,
Data in the database having the character string as a keyword is displayed or output as voice. In addition, a character string that is modified and displayed in a teletext broadcast visually indicates the importance of the teletext.

[0008]

FIG. 1 is a block diagram showing the overall configuration of an information collection support apparatus according to an embodiment of the present invention. The character signal demodulation device 101 demodulates a character multiplex modulation signal including a character broadcast. The character encoding device 102 converts the demodulated teletext into an encoded character string. Database device 103
Stores data in the form of images, sounds, or documents. The database search device 104 compares the encoded character string with the data of the database device 103, outputs the position information of the keyword in the text broadcast, and searches according to the user's instruction transmitted from the input / output control device 105. Output data. The input / output control device 105 processes a user instruction input from the user instruction device 106 and outputs the processed instruction to the database search device 104. Then, the character broadcast output from the character signal demodulation device 101 is modified with the position information of the keyword output from the database search device 104, and further, the search data is synthesized according to the user's instruction, and the image display device 107 and the audio output device are combined. Output to 108.

Next, an operation example of the present invention will be described. The text broadcast demodulated by the text signal demodulator 101 is displayed on the image display device 107 as an information screen 201 as shown in FIG. The user instruction pointer 203 is the user instruction device 1
06 corresponds to the input. The character encoding device 102 converts the teletext into an encoded character string. FIG. 3 shows the internal structure of the database search device 104. The keyword division device 301 divides the encoded character string output from the character encoding device 102 into morpheme sequences using a morphological analysis technique in natural language processing. FIG. 4 shows an example in which the teletext on the information screen 201 shown in FIG. 2 is divided into morpheme strings.

[0010] Assume that the database device 103 stores commentary data on current terminology such as "basic knowledge of modern terminology". The keyword extracting device 303 outputs, from the database device 103, “Administrative Reform”, “Information Disclosure”, “Supreme Court”, “Sanwa Bank”,. . . Is obtained. The keyword specifying device 302 compares the morpheme sequence shown in FIG. 4 with the above-mentioned keyword set, further receives user's instruction information from the input / output control device 105, and determines the data keywords to be searched from the database device 103. Output. Also,
It outputs image modification information for modifying an image displayed on the image display device 107. The image modification information includes the position and the range of the keyword existing in the teletext.

FIG. 5 shows the internal structure of the input / output control device 105. As for the output of the user instruction device 106, the instruction history up to the present time is managed by the instruction history holding device 503, and is output to the database search device 104 as user instruction information. The image synthesizing device 501 includes the character encoding device 102
Broadcast output from the server and the database search device 10
The image modification information and the search data output from 4 are synthesized and edited with reference to the contents of the instruction history storage device 503, and output to the image display device 107 as an image signal. The voice synthesizer 502 refers to the contents of the instruction history holding device 503 and synthesizes a character string included in the search data by voice, or outputs voice data included in the search data to the voice output device 108 as a voice signal. A text broadcast displayed on the image display device 107 after the text broadcast on the information screen 201 in FIG. 2 is modified by the image modification information is shown in the information screen 601 in FIG.

The data selection device 304 selects data having a keyword specified by the keyword identification device 302 from the database device 103 and outputs the selected data. The search data holding device 305 holds the data searched by the data selection device 304 in advance and reduces the user's information transmitted from the input / output control device 105 in order to reduce the waiting time until the data is provided to the user. Output to the input / output control device 105 according to the instruction information.

Assuming that the database device 103 stores personal name data such as "keeper (business, economy, politics)" and the like, a set of keywords included in the data, "Reijiro Kakuta", "Imaizumi" Masataka ",. . . Is performed, and a text broadcast that has undergone a modification different from the text broadcast on the information screen 601 in FIG. 6 is displayed on the image display device 107 like the information screen 701 in FIG.

When the user moves the instruction pointer 703 shown in FIG. 7 using the user instruction device 106 to indicate the modified character string “Reijiro Kakuda”, the search data holding device 305 already searches for the character string. The stored data is displayed as shown in a search screen 802 in FIG. 8, and the user can quickly and easily obtain detailed information.

[0015] A teletext broadcast is treated as an encoded character string as one piece of data, and a keyword is assigned to the data and stored in the database device 103, whereby a user-specific database such as a scrapbook can be realized. . In addition, by replacing the teletext with another text database device, information can be efficiently collected from a plurality of databases.

[0016]

The user can quickly and easily collect necessary information in detail simply by giving a simple instruction to the apparatus.
