2. Description of the Related Art In a conventional database system for providing, for example, computer communication services, when a user operates a terminal to access a center system, a predetermined menu for information (data) search is displayed. (This is performed, for example, by executing a predetermined search program in the center system), and by operating the terminal further in accordance with the menu, desired data can be obtained.

That is, for example, in a center system, data is stored in a hierarchical manner according to its type (genre), so that the user can trace the menu to the hierarchy in which desired data is stored. By going
The desired data can be obtained.

[0004]

Therefore, the user needs to operate the terminal until he / she enters the desired data hierarchy. Therefore, for example, a user who desires information (data) of the same genre on a regular basis, such as every day, has to perform the same operation each time he / she accesses the center system, which is troublesome for the user. There was an issue that made me feel.

Further, in the center system, when a large amount of information (data) of genres is prepared, there is a problem that it takes time to enter a desired data hierarchy.

Further, the center system and the user's terminal are usually connected by a telephone line, and if it takes time to obtain desired data, the user is burdened with an excessive communication cost. There were challenges.

Therefore, for example, on the side of the center system, information (data) registered in the center system via a broadcasting satellite (BS) or a communication satellite (CS).
The user side receives the contracted information transmitted from the center system,
A method of searching for desired information from the received information can be considered.

However, in this case, it is necessary to temporarily store all the received information in order to retrieve the information, and in order to meet the requests of an unspecified number of users, the center system is Since a huge amount of information (the number of genres is huge and the amount of information of one genre is also huge) needs to be transmitted, there is a problem that a huge amount of storage media is required.

Further, in this case, the user has to search for a desired one from a huge amount of information, which causes a problem for the user.

That is, for example, when the data transmitted from the center system relates to newspapers issued by a plurality of newspaper companies (for example, A and B newspapers), for example, first, an article on politics in the A newspaper. , And then when you try to read an article about economy in B newspaper, repeat the search operation of the same procedure,
It was necessary to retrieve the politics article of newspaper A and the article of economy of newspaper B from the recording medium.

Further, even if the data transmitted from the center system is related to one newspaper issued by one newspaper company, for example, first, an article about politics is read, and then an article about politics is read. When trying to read an article about economics, it was necessary to repeat the search operation of the same procedure to retrieve an article about politics and an article about economy from the recording medium.

The present invention has been made in view of such a situation, and makes it possible to easily obtain information (data) desired by a user.

That is, the data in the database is edited into article data in a format that is easy to search on the receiving (recipient) side, for example, on each page. For example, by this editing, a screen for search (this screen is composed of, for example, image data) is created in which the layout is unchanged and only the headline is visible and the paper surface is reduced in size.
Furthermore, in order to be able to display the article corresponding to this headline, the relation between the search screen (headline) and the article describing this detail (this article is composed of text data, for example) Is done.

For the edited newspaper article, for example, the genre of the newspaper article (hereinafter, appropriately referred to as search information) is necessary as information (hereinafter, referred to as search information) necessary for the receiving side to perform the search (selection). Type), the page of the newspaper on which the newspaper article is written, the name of the publisher of the newspaper (or the identification number given to the newspaper in advance), the newspaper name, and other indexes (for example, ,
The one decided by the newspaper publisher who is the information provider) is attached. In this way, the data edited in a form that can be easily searched by the receiving side is transmitted to the broadcasting center (broadcasting station) 3 via the terrestrial data line.

Further, in a newspaper company which is an information provider, from a television station which is also an information provider, for example, additional text information (text data) and images (moving images) which are not stored in the large-scale computer 1 are stored. Alternatively, video information (image data) that is information of still images), audio information (voice data) that is information of audio (for example, information of news programs corresponding to newspaper articles, etc.) are transmitted. At the workstation 2 of the newspaper company, information from the TV station (text data, image data, audio data)
Is also edited in a format that can be easily searched by the receiving side (in this case, as described above, information (text data,
(Image data, audio data) is used to edit the layout when displaying on screen, add search information to that information, and associate that information with newspaper articles corresponding to that information), broadcasting It is transmitted to the center 3.

Further, in the broadcasting center 3, information in a database owned by other information providers (for example, catalog information of products used for shopping services, game programs, expected information such as horse racing, race results thereof, theaters, etc.) Information, movie information, product and other advertisements, magazine and book data, etc.) are edited and transmitted by the interface control unit 101 in the same manner as in the above-described workstation 2 of a newspaper company.

Here, in the interface control unit 101, as in the case of the workstation 2, search information is added to the information (data) in the database. This is, for example, as follows depending on the type. To be done. That is, for example, with respect to product (commodity) catalog information, product classification (for example, audio products, food,
Clothing, sports equipment, etc., product name (product name) (or general name), manufacturer name (manufacturer name), product price, keyword for product, product index set by information provider (for example, , If the product (commodity) is clothing, then its dedicated ID, etc.)
It is added as search information. In addition, for example, to a game program, a character name that appears in the game, a selling agency (maker name), and the like are added as search information.

Further, the interface control unit 101
In the same manner (in the workstation 2 as well), the information (data) in the database is put together in a predetermined group unit for each related information, and is formed in a format that allows the receiving side to identify the group unit. Has been done.

That is, for example, the catalog information of a certain product of a certain manufacturer is, for example, text data corresponding to the description of the specifications of the product, video data (image data) of the product photographed, voice data introducing the product, and the like. In the interface control unit 101, these data are set as one group of data.

FIG. 4 shows a format (A mode format) of digital channel data which is 4-phase DPSK modulated. As shown in the figure, one frame of data is composed of a total of 2048 bits of horizontal 64 bits and vertical 32 bits. A frame synchronization signal, a control signal, and a range bit signal are arranged (recorded) in the first range of 2 bits × 32 bits.

Since one frame of data is transmitted in 1 ms, the transmission rate is 2.048 Mbps.

The frame synchronization signal is a signal for synchronizing each frame. The control signal has 16 bits as one unit, and the first 1 bit indicates which mode is the A mode or the B mode. Depending on the next 2nd bit and 3rd bit, whether the television audio signal (audio signal accompanying the video signal) (arranged in audio 1 and 2 in FIG. 4) is a stereo signal or a monaural 1-channel signal It is designed to indicate whether there is a signal of two channels of monaural.

The 4th bit and the 5th bit indicate whether the additional signal added to the sound other than the television sound (arranged in the sounds 3 and 4 in FIG. 4) is a stereo sound signal or the sound of the monaural 1 channel. It indicates whether it is a signal, a monaural 2-channel audio signal, or data other than audio. Bits 6 to 15 are extension bits for future use. The 16th bit is a code for indicating whether or not the audio output is suppressed.

The header consists of at least the service identification code and its error correction code (check bit).
The service identification code includes, for example, a code for identifying related information and multimedia data.

To the independent data channel, the related information output by the encryption circuit 11 shown in FIG. 3 and the multimedia data output by the data scrambler 14 are allocated in packet units, and the packets are allocated. A service identification code is set corresponding to data (whether the data is related information or multimedia data).

On the receiving side, the scramble key of the information provider can be detected by monitoring the packet of related information (scramble key, common information, receiving device ID, contract content, work key, etc.). When the data receiving device having the receiving device ID included in the transmitted related information matches the contract content, it becomes possible to download the information (multimedia data) provided by a predetermined information provider. .

The above data is transmitted from the broadcasting center 3 in FIG. 1 to the satellite 4, and further transmitted from the satellite 4 to, for example, the receiver (contractor) in each home. In each home, the signal transmitted from the satellite is received by the outdoor device (parabolic antenna) 5 and further converted into a predetermined intermediate frequency signal (IF signal). This IF
The signal is input to the data receiving device 6. The IF signal input to the data receiving device 6 is demodulated there, and is recorded in the built-in storage device 31 (FIG. 5) or a recording (storage) medium such as the MD 8 detachable in the recording medium slot. Alternatively, the received data is temporarily recorded in the storage device 31, and then a desired one is searched for and downloaded to the MD 8.

After recording (storing) data in MD8,
The user can mount the MD 8 on, for example, the portable terminal 9 or the desktop type user terminal 10, and can retrieve and display the desired one from the received data. Further, the user can read the data recorded in the storage device 31, output it to the monitor device 7 and display it if necessary.

That is, as shown in FIG. 8, first, in step S11, the user operates the operation unit 3
By operating 7, the multimedia data (newspaper data) to the CPU 34 based on the selection information table
Is requested (user article request), the process proceeds to step S12, and the CPU 34 refers to the selection information table recorded in the storage device 31, and records it in the storage device 31 based on the selection information table. The retrieved newspaper data is searched.

Here, FIG. 9 shows an example of the selection information table. In the selection information table, genres of newspaper articles, newspaper names, and pages of newspaper pages are registered as selection information.

In this case, in the CPU 34, the first set of selection information in the selection information table (FIG. 8) (all selection information registered in the first row) ("general", "A newspaper", "1.2"
・ 22 ・ 23 ") is referred to, and the newspaper data containing them as search information, that is, the genre of newspaper articles is general, the newspaper name is A newspaper, and the page is 1, 2, 22, or 23. Newspaper data to which at least information has been added is retrieved from the storage device 31. As a result, newspaper data of pages 1, 2, 22, and 23 of A newspaper, which correspond to articles belonging to general genres,
The newspaper data retrieved from the storage device 31 is output to, for example, the monitor device 7 and displayed in step S4 (FIG. 6) described above.

After that, the process proceeds to step S13, and the operation unit 3
The CPU 34 determines whether or not a termination operation has been performed so that 7 terminates the personal newspaper program. When it is determined in step S13 that the ending operation has been performed, the processing ends.

On the other hand, if it is determined in step S13 that the ending operation has not been performed, the process returns to step S11.

In this case, when a user article request is further made in step S11, the process proceeds to step S12, in which the CPU 34 sets the next set of selection information ("economy", "B newspaper") in the selection information table (FIG. 8). , "3 to 5"), whereby the newspaper article genre is economic, the newspaper name is A newspaper, and at least the selection information with pages 3, 4, or 5 is added. Data, that is, newspaper data of 3 to 5 pages of B newspaper, which corresponds to articles belonging to the genre of economy, is stored in the storage device 3.
1 is searched and displayed on the monitor device 7 as described above.

Thereafter, each time a user processing request is made in step S11, the registered contents of the selection information table are sequentially referred to, the newspaper data is retrieved from the storage device 31, and displayed on the monitor device 7. That is, in this case, after the newspaper data of pages 3 to 5 of B newspaper, which correspond to articles belonging to the genre of economy, are searched and displayed,
Furthermore, newspaper data of pages 1 to 6 of the C newspaper, which corresponds to articles belonging to the genre of industry, newspaper data of pages 1 to 5 and 12 of the D newspaper,
The articles corresponding to the articles belonging to the genre of sports are sequentially searched and displayed.

Therefore, the user only needs to set the selection information corresponding to the search information of the desired newspaper data in advance to obtain (collect the desired newspaper data without performing a troublesome operation (search operation). ) Can read newspaper articles (newspaper data). Further, in this case, by registering the selection information (a set of selection information) in the selection information table in a predetermined order, the user can read the newspaper in which the search information matching the selection information is added in the registration order. You can read the data. That is, the user can read the newspaper data in a desired order.

Further, for example, when the user wants to read a newspaper article in a genre different from the conventional one, he / she only needs to change the registered contents of the selection information table.

The display of newspaper data on the monitor device 7 is performed for each retrieved article or page. However, in this case, since the data to be searched (multimedia data) is limited to newspaper data, the monitor device 7 displays the data in article units or page units, but the display unit is the search target data. It is supposed to be changed by. That is, when the data to be searched is, for example, magazine data, product catalog information (catalog information), or the like, the searched data is displayed for each page of the magazine or for each product. Done.

Further, the CPU 34 does not refer to all the sets of selection information registered in the selection table, but specifies only some of them by operating the operation unit 37, and only the specified ones are specified. Can be referred to. That is, in the above case, for example, referring to the first set of selection information ("general", "A newspaper", "1.22.22.23"), 1, 2, 22, or 23 of A newspaper. In the newspaper data of a page, articles belonging to a general genre are searched and displayed, but other than this, for example, a set of selection information (“general”,
Of the "A newspaper" and "1.22.22.23"), for example, pay attention only to the genre "general" and the newspaper name "A newspaper",
It is possible to retrieve and display newspaper data belonging to a general genre of all the newspapers of A newspaper.

For example, paying attention only to the newspaper name "A newspaper" and the pages "1.2.22.23",
Newspaper data on pages 2, 22, and 23 can be searched and displayed. However, in newspapers, the number of pages and the allocation position of the article to the paper usually differ depending on the day. Therefore, when reading an article of a predetermined content at all times, as described above, the genre (and newspaper name) to which the article belongs ) Is preferably used to search newspaper data.

Further, for example, the page "1 / 2.2.2.2"
All newspapers in contract, in this case A, D newspapers 1, 2, 22 and 23, paying attention only to "3".
The newspaper data corresponding to the page can be searched and displayed.

In the above case, the data (multimedia) to be searched is newspaper data,
In the selection information table, the genre of newspaper articles, the newspaper name, and the selection information of pages on the newspaper surface are registered (FIG. 9), but the data to be searched is, for example, magazine data or products. In the case of catalog information (catalog information) or the like, the selection information registered in the selection information table may be changed according to the search information added to it.

By the way, in the above case, as shown in FIG. 6, in step S2, all the multimedia data from the decoder 33 (FIG. 5) is temporarily recorded in the storage device 31, and then used in step S3. Since the person performs a filtering process (filtering process after recording) for searching (selecting) a desired one (necessary one), when a large amount of data has been contracted for reception, a large amount of data is recorded as the storage device 31. It is necessary to use one having a capacity.

Further, in addition to the multimedia data desired by the user, undesired data (unnecessary data) are recorded in the storage device 31, so it is said that the storage device 31 is being used efficiently. Hard to say.

Therefore, the data obtained as a result of the filtering process after recording in step S3 of FIG. 6, that is, the data desired by the user is recorded in the predetermined region of the storage device 31 as described above, and the other region is recorded. The method of deleting the data recorded in is conceivable.

In this case, the utilization efficiency of the storage device 31 can be improved, but as described above, the decoder 33 is used.
The multimedia data from the once storage device 31
Is stored (recorded) in the storage device 31,
A lot of recording capacity is required.

Therefore, the data receiving device 6 (FIGS. 1 and 5)
In addition to the flow chart shown in FIG. 6, it is possible to operate according to the flow chart shown in FIG. In this case, first, the tuner 32 and the decoder 33 (FIG. 5) perform the same processing as the processing in step S1 in FIG. 6 on the IF signal from the exterior / exterior value 5 (step S21), thereby descrambling. When the generated multimedia data is output from the decoder 33, the CPU 34 sequentially transfers the data to the RAM 35 and stores the data in the above-described group unit.

Further, in the CPU 34, the search information added to the group unit data stored in the RAM 35 is the selection information (a set of selection information) registered in the selection information table stored in advance in the storage device 31. Is determined (whether the search information includes selection information or not). Then, the group unit data to which the same search information (including the selection information) as the selection information is added is read from the RAM 35, and the other data is deleted from the RAM 35. That is, selection of multimedia data based on the selection information (selection of multimedia data corresponding to the selection information) is performed in group units (this process is hereinafter referred to as filter process before recording, as appropriate) ( Step S22).

In the filtering process before recording, the RAM 3
The multimedia data read from 5 is transferred to the storage device 31 and recorded (stored) (step S2).
3). Then, after that, when the operation unit 37 is operated to display the multimedia data recorded in the storage device 31, the multimedia data is stored in the storage device 3, for example.
1 is read out in the order recorded, and for example, the monitor device 7
Is supplied to the display circuit 38 of FIG. The display circuit 38 drives the monitor 39 in response to the supplied multimedia data, whereby the monitor 39 displays a screen corresponding to the multimedia data (step S24).

The multimedia data obtained as a result of the filtering process before recording can also be recorded (stored) in the MD8, so that the MD8 can be transferred to a portable terminal as in the case described above. It is designed to be attached to the container 9 or the desktop type user terminal 10 so that the data recorded therein can be displayed.

In the above case, the decoder 3
Although the multimedia data from 3 is temporarily stored in the RAM 35 in units of groups, the selection is performed based on the selection information. However, the multimedia data is temporarily stored in the RAM 35 according to the processing speed of the CPU 34. It is possible to make the selection without causing it.

Next, details of the filter processing before recording in step S22 of FIG. 10 will be described. Note that, here, it is recorded that the user (recipient) has contracted with the information provider to receive (view) the product catalogs of the four manufacturers S, T, U, V, for example. The previous filter processing will be described.

First, as described above, the user activates the registration program, creates the selection information table, and records (stores) it in a predetermined recording (storing) area of the storage device 31 or the RAM 35.

Here, as the selection information, for example, for catalog information of a product (commodity), the same information as the search information added thereto, that is, the above-mentioned product classification (genre) and product name (commodity). Name), manufacturing company name (maker name), product price, keyword, etc. can be used.

After that, the above-mentioned search program is activated, and the filtering program, which is one of the subroutines, is executed by the CPU 34, so that the filtering process before recording is performed. That is, as shown in FIG. 11, the catalog data from the decoder 33 (data relating to products manufactured by companies S to V among multimedia data) is sequentially transferred to the RAM 35 in units of groups and temporarily stored. (Stored). Then, in step S32, the CPU 34 causes the storage device 3 to operate.
The selection information table recorded in No. 1 is referred to, the flow proceeds to step S33, and any one of the selection information sets (or selection information) registered in the selection information table and RA
It is determined whether or not the search information attached to the catalog data for each group stored in M35 is the same (whether the catalog data satisfies the condition for each group).

In step S33, it is determined that the search information attached to the catalog data for each group stored in the RAM 35 is not the same as any of the sets of selection information (or selection information) registered in the selection information table. If so, the process proceeds to step S35, and the catalog data for each group is deleted (discarded) from the RAM 35.

On the other hand, in step S33, the RAM 3
If it is determined that the search information attached to the catalog data in group units stored in 5 is the same as any of the selection information sets (or selection information) registered in the selection information table, the process proceeds to step S34. Then, the catalog data for each group is read from the RAM 35 and recorded in the storage device 31 in step S23 (FIG. 10) described above.

Here, FIG. 12 shows an example of the selection information table. In the selection information table, the genre of the product, the manufacturer, the price (price range), and the keyword are registered as the selection information.

In this case, step S3 by the CPU 34
According to the processes of 2 to S35, first, the first set of selection information of the selection information table (FIG. 12) (all selection information registered in the first row) (“audio”, “S company”, “<5
0000 (less than 50000 yen) "," MD ") is referred to (step S32), and the search information added to the catalog data for each group stored in the RAM 35 is
At least "audio", "S company", "less than 50,000 yen" (the price of the product added as search information is 5
It means that it is less than 0000 yen), and it is determined whether or not the condition that "MD" is included is satisfied (step S33). When the catalog data satisfies the above-mentioned condition, that is, the genre of the product introduced by the catalog data is audio (the product is an audio product), the manufacturer is S company, and the price is 50.
If it is less than 000 yen and the keyword is MD (in this case, the product name is MD), the catalog data is read from the RAM 35 (step S34) and recorded in the storage device 31 in step S23 described above. It

On the other hand, when the catalog data does not satisfy the above condition, the CPU 34 causes the CPU 34 to select the next set of selection information (“food”, “T company”, “4”) in the selection information table (FIG. 10).
000-5000 "," crab "). Then, the genre of the product introduced by the catalog data is food, the manufacturer (manufacturing) is T company, and the price is 4000.
If the keyword is crab (in this case, food is crab) within the range of up to 5,000 yen, the catalog data is recorded in the storage device 31 as described above.

On the other hand, when the catalog data does not satisfy the above condition, the next set of selection information in the selection information table is referred to and the same processing is performed.

After that, in the CPU 34, the search information added to the catalog data is the last set of selection information (“food”, “T” in the selection information table (FIG. 10)).
Company ”,“ 4000-5000 ”,“ crab ”) is not included, the catalog data is deleted from the RAM 35 (step S3).
5).

After the processing of step S34 or S35, the process proceeds to step S36, and it is determined whether or not the catalog data for each group is still stored in the RAM 35. When it is determined in step S36 that the catalog data for each group is still stored in the RAM 35, the process proceeds to step S37, where the target of the process by the CPU 34 is the next catalog data for each group stored in the RAM 35. It is changed, and the process returns to step S32. If it is determined in step S36 that the catalog data for each group is not stored in the RAM 35, the process ends.

Therefore, in this case, the same effect as in the case of FIG. 6 described above can be obtained. Further, in this case, the multimedia data (catalog data) from the decoder 33 is stored in the storage device 31 after being selected by the user.
It is possible to reduce the capacity and improve the utilization efficiency.

In the case of FIG. 11, as in the case of FIG. 6, the CPU 34 does not refer to all the sets of selection information registered in the selection table, but only some or only one of them. Can be referred to.

By the way, in the process according to the flowchart of FIG. 10, the recording capacity of the storage device 31 can be reduced as described above, but the selection information table of the multimedia data from the decoder 33 is stored in the selection information table. Since the data that does not correspond to the registered selection information (or set of selection information) is deleted, even if any of the deleted multimedia data is needed later, the user can Can't get

Therefore, the data receiving device 6 (FIGS. 1 and 5)
In addition to the flowcharts shown in FIGS. 6 and 10, for example, the operation according to the flowchart shown in FIG. 13 can be performed.

That is, in this case, the tuner 32 and the decoder 33 (FIG. 5) perform the same processing as the processing in step S1 in FIG. 6 on the IF signal from the exterior / exterior value 5 (step S41). When the descrambled multimedia data is output from the decoder 33, the pre-recording filtering process described with reference to FIG. 11 is performed on the multimedia data (step S4).
2).

Then, the multimedia data obtained as a result of the filtering process before recording is transferred to the storage device 31 and recorded (step S43), and then the operation unit 37.
Is operated to display the multimedia data recorded in the storage device 31, the multimedia data recorded in the storage device 31 is subjected to the post-recording filter processing described in FIG. 8 (step S44).

The multimedia data obtained as a result of the filtering process after recording is supplied to, for example, the monitor device 7,
Then, it is displayed (step S45) (as described above, the data can be supplied to a predetermined area of the MD 8 or the storage device 31 to be recorded (stored)).

Therefore, in this case, the multimedia data obtained as a result of the filtering process before recording should be in a wider range than the multimedia data obtained as a result of the filtering process after recording (pre-recording selection information described later). It is expected that the data selected based on the table will have a wider range than the data selected based on the post-recording selection information which will also be described later), that is, for example, by filtering before recording. Data is obtained,
Further, in order to obtain the truly desired data by the filtering process after recording, the selection information table used in each of the filtering process before recording or after recording (hereinafter, appropriately, respectively, the selection information table before recording or the selection information table after recording). By creating a selection information table)
If the data deleted (not selected) by the filtering process after recording is the data that was not deleted by the filtering process before recording when needed later, change the registered information in the selection information table after recording You can get the data just by doing.

Next, in the filtering process after recording or the filtering process before recording shown in FIG. 8 or FIG. 11, respectively, the selection information table corresponds to the multimedia data desired (necessary) by the user. Although the selection information is registered and the multimedia data corresponding to the selection information is selected (searched), in this case, for example, the search information is changed (including addition and deletion) on the information provider side. When this happens, the multimedia data that was previously selected may not be selected.

This can be dealt with by changing the registered contents of the selection information table. In this case, every time the search information is changed, the information provider notifies the user (receiver) of the change. To that effect, the user must change the selection information table.

Further, in the above-mentioned case, even if the information provider has information that the user wants the user to see (for example, sponsor advertisement, latest information, etc.), the filter (before or after recording) may be used. May be deleted in the process.

Therefore, in advance, in the selection information table,
The selection information corresponding to the multimedia data that the user does not want (is not required) is registered, and the filtering process after recording or the filtering process before recording selects (searches for) the multimedia data that does not correspond to the selection information. ) Can be done.

That is, the filtering process after recording shown in FIG. 8 can be performed according to the flowchart shown in FIG. 14, for example. According to the case shown in FIG. 14, multimedia data that does not correspond to any selection information registered in the selection information table is searched from the storage device 31 in step S101.

The filter processing before recording shown in FIG. 11 can be performed according to the flowchart shown in FIG. 15, for example. According to the flowchart of FIG. 15, the same processing as in the case of FIG. 11 is performed in each step, but after the determination processing of step S33,
Only the subsequent processing is different depending on the determination result. That is, in the case of FIG. 11, when the determination result of step S33 is true (YES) or false (NO), then, respectively, step 3
The processing of 4 or S35 is performed, but in the case of FIG. 15, when the determination result of step S33 is true (YES) or false (NO), the processing of step 35 or S34 is performed, respectively.

Therefore, in the case of FIG. 15, in step S33, the search information attached to the multimedia data for each group stored in the RAM 35 is not the same as any of the selection information registered in the selection information table. If it is determined that the multimedia data for each group is stored in the RAM 35, the process proceeds to step S34.
Read from.

On the other hand, in step S33, the RAM 3
If it is determined that the search information attached to the group-based multimedia data stored in 5 is the same as any of the sets of selection information registered in the selection information table, the process proceeds to step S35, and the group is selected. The unit of multimedia data is deleted (discarded) from the RAM 35.

As described above, in this case, even if the search information is added or changed on the information provider side, it is possible to prevent the previously selected multimedia data from being deselected. Further, the information provider can forcibly display the information that the user wants to show to the user.

Although the present invention has been described above by taking the case of receiving multimedia data as an example, the present invention can be applied to the case of receiving only text data or the like instead of multimedia data. .

In step S42 or S44 shown in FIG. 13, the filtering process before or after the recording described in FIG. 15 or 14 is performed, and in step S42 shown in FIG. It is also possible to perform the filter processing before recording and perform the filter processing after recording shown in FIG. 14 in step S44, or perform the filter processing before recording shown in FIG. 15 in step S42. In step S44, the post-recording filtering process shown in FIG. 8 may be performed.

Further, when the MD 8 is mounted on the portable terminal 9 and the user terminal 10 and the data recorded therein is displayed, the portable terminal 9 and the user terminal 10 are connected to the above-mentioned FIG. 8 or FIG. It is possible to apply the filtering process after recording shown in (4) to the data recorded in the MD 8.
