2. Description of the Related Art Recently, moving images, still images, voices, texts,
There is an environment where computers can handle multimedia data in which multiple types of data with different properties are associated with each other, and CD-ROM (Compact Disc Read Only Memo)
A technique for loading multimedia data recorded on a recording medium such as ry) onto a computer and reproducing the multimedia data while maintaining the relation between the data is being developed. Applications of multimedia data include electronic book applications and video games. These are e-book players,
It is reproduced by an information reproducing device such as a game machine or a personal computer.

[0003] Among them, the electronic book application constructs multimedia data as a single article with a story, and combines these articles to show contents that have been conventionally expressed in paper media such as magazines and books. It is an electronic representation on the screen. In particular, in the electronic book application having the contents of the dictionary, the dictionary, and the catalog, the user can select the multimedia data to be reproduced by using the search function.

An example of the above-mentioned conventional information reproducing apparatus will be described below with reference to the drawings. FIG. 8 is a block diagram showing the structure of a conventional information reproducing apparatus. This information reproducing apparatus includes a recording unit 81, a takeout unit 82, a reproduction output unit 8
3, an input unit 84, a search unit 85, and a reproduction control unit 86.

The recording section 81 is an optical disk (CD-ROM) which is an information recording medium in which the electronic book application is recorded as digital data. The multimedia data recorded on the optical disc includes a plurality of material information, a plurality of information blocks including a search information block, keyword index information, and reproduction path information. Here, the “material information” refers to individual files such as voices, still images, texts, and moving images that are materials of the electronic book application.
The “information block (hereinafter abbreviated as a scenario)” corresponds to a scene to be reproduced, represents a presentation method that defines which material information and how to present it to the user, and the material information to be reproduced, display position, and display. It is a file that defines the size. "Keyword index information" is table data,
The correspondence between each scenario keyword and the corresponding scenario is shown. The "search scenario" is a type of scenario, and refers to a scenario having a plurality of keywords as search conditions and designation of material information indicating a selection box for displaying a list of those keywords and its presentation method. The “playback path information” is a file that defines the playback order of a plurality of scenarios.

The take-out unit 82 is a drive unit for the recording unit 81, and reads out and outputs the file recorded at the designated address. The reproduction output unit 83 performs a predetermined process on each of the digital data strings that are input material information to convert them into an analog audio signal and an analog video signal, and attaches the speaker device and the display at an output timing according to the control signal. Audio output and video output are performed from the device.

The input unit 84 receives a progress control request and a keyword specification request from the user via an attached input device. The progress control request is a request by the user to advance or return the article in the e-book application. The keyword specification request is a request to specify one of the keyword groups displayed in the selection box presented by the search scenario.

The retrieval unit 85 is composed of a CPU and its operation program. When a keyword is designated, the retrieval unit 82 reads out the keyword index information, searches it, and retrieves all scenarios corresponding to the designated keyword. The recording address value on the recording unit 81 is calculated. The reproduction control unit 86 is composed of a CPU and its operation program, and reads out and retains reproduction path information from the recording unit 81 via the extraction unit 82 at the time of initialization such as power-on or reset.
When the input unit 84 receives the progress control request, the scenario to be reproduced is determined according to the reproduction path information, the scenario is read from the recording unit 81 via the extraction unit 82, and the material information to be reproduced and the presentation method are determined according to the scenario. Playback output control is performed on the extraction unit 82 and the playback output unit 83. Further, if the scenario is a search scenario, the playback control unit 86 determines and specifies text data that is a keyword group to be played back and image data that is a selection box for displaying the list in accordance with the search scenario. According to the presenting method, reproduction control is performed on the extraction unit 82 and the reproduction output unit 83, and this is reproduced and output. The reproduction control unit 86 waits for the input unit 84 to accept the keyword designation request, and determines the keyword selected by the user from the read keyword group. The reproduction control unit 86 that has determined the keyword selected by the user outputs this keyword to the search unit 85, determines scenarios corresponding to all the recording address values output as search results from the search unit 85 as reproduction targets, Reproduction control for continuously reproducing all of these scenarios is performed by the same processing and procedure as described above.

The operation of the information reproducing apparatus configured as described above will be described below by taking an application having the reproducing path structure shown in FIG. 9 as an example. 9 in FIG.
Reference numeral 1 is a search scenario, and 92 to 98 are scenarios.
The reproduction path information indicating the reproduction path is held in the reproduction controller 86 at the time of initialization. The playback control unit 86 follows the scenario 9 placed at the beginning of the route according to the held playback route information.
2 is determined as the reproduction target, and the scenario 92 is taken out by the extracting unit 82.
It is read from the recording unit 81 via. The reproduction control unit 86 that has read the scenario 92 determines the material information to be reproduced specified in the scenario 92, and reproduces and outputs the material information by the presentation method specified in the scenario 92. The extraction unit 82 and the reproduction output unit 83. Do against. When the reproduction output of the scenario 92 is completed, the reproduction control unit 86 waits for the progress request to be accepted by the input unit 84, and reads the search scenario 91 from the recording unit 81 according to the reproduction order of the reproduction path information. The reproduction control unit 86 that has read the search scenario controls the reproduction output of the text data of the keyword group and the image data that forms the selection box according to the presentation method defined in the search scenario 91. The extraction unit 82 and the reproduction output unit. 83. The playback control unit 86 waits for the input unit 84 to accept the keyword designation request, determines one keyword from the keyword group designated by the search scenario according to the keyword designation request, and outputs this to the search unit 85. To do. The search unit 85 to which the keyword is input reads the keyword index information from the recording unit 81 via the extracting unit 82, searches this with the keyword selected by the user, and reproduces all the recording address values obtained as the search result. Output to 86. The reproduction control unit 86 similarly performs reproduction control of continuously reproducing the scenarios corresponding to all the recording address values acquired as the search result. For example, if the recording address values of the scenario 95 and the scenario 96 are acquired as the search result, the scenario 95 and the scenario 96 are continuously reproduced.

In the electronic application catalog application, multimedia data for introducing electric products is arranged in each scenario, and a plurality of keywords such as item, product name, price, etc. are set for each scenario, and a keyword of a search condition is set by searching. All scenarios that match with will be extracted and played continuously. For example, by designating a keyword such as "TV" or "video", multimedia data in which the keyword "TV" or "video" is set is reproduced. Further, since a plurality of keywords are set for the same scenario, a scenario in which three keywords “AV device”, “TV”, and “100,000 yen level” are set is searched by any of these keywords. It will be.

[0011]

However, in the above configuration, only the scenario group matching the specified keyword is extracted and continuously reproduced, and the video for each scenario to be reproduced is searched by any keyword. Since the same applies in the case of, there is a problem that it is difficult for the user to keep track of which search condition the display content is caused by. For example, in a scenario in which three keywords “AV device”, “TV”, and “100,000 yen level” are set, the same video display and audio output are obtained when any of these keywords is searched. for that reason,
When there are many search results or when there are many continuous playback scenarios, the user could not keep track of which search condition caused the display content.

One method for solving this is to prepare one scenario for each keyword, but it is necessary to prepare a separate scenario for each keyword, which lengthens the editing work time and allows the keywords to be recorded on the optical disk. Another problem that the total number decreases is not realistic. In view of the above problems, the present invention can change the output content of the search result by reflecting the user's search purpose such as the search keyword after the search, and the user can easily grasp the correspondence relationship between the output content and the search condition. It is an object of the present invention to provide an information reproducing device that can be used.

An information reproducing apparatus according to an embodiment of the present invention will be described below with reference to the drawings. FIG.
(A) is a block diagram showing a configuration of an information reproducing apparatus in an embodiment of the present invention. The information processing apparatus includes a recording unit 1
1, take-out unit 12, holding and combining unit 13, reproduction output unit 1
4, an input unit 15, a search unit 16, a catalog determination unit 17, and a control unit 18.

In FIG. 1A, the recording section 11 is an optical disk (CD-ROM) which is an information recording medium for recording the electronic book application as digital data. The multimedia data recorded on this optical disc includes a plurality of materials, a plurality of scenarios including a search scenario, a modification scenario, and a composition scenario, keyword index information, reproduction path information, catalog information, catalog index information, catalog classification information. Is recorded. Also, the recorded data on the CD-ROM is taken out in file units, and
There is correspondence table information between the file name and the recording address on the ROM, and the recording data can be read by designating the file name.

Here, the "material" is a file that stores individual digital data such as voice, still image, text, and moving image that constitute the electronic book application. The “scenario” represents a presentation method that defines which material information is to be presented to the user and how, for each material information to be reproduced,
It is a file that defines layout information that specifies a display layer, a display position, and a display size, and synchronization timing. The data format of the "scenario" is shown in FIG. In the same figure (a), "scenario No." is a file name, an identification number unique to each scenario, "material synchronization timing" is a presentation timing of each material information, and presentation start time and end time information. "Material information group" indicates a plurality of material information. “Material information” is composed of “material No.”, “material file name”, “material type”, and “layout information” as shown in FIG. Material N
"o." is an identification number unique to each material information, "Material type" is the data type such as video, audio, still image, animation, text data, and "Material file name" is the material that stores the data. The file name of “” and the “layout information” indicate the display position, display size, and display layer that should be displayed. For example, a scenario is a material to be displayed and its display, as in the scenario display screen shown in FIG. If the scenario introduces TV in an application that contains a catalog of electric appliances, a still image of the appearance of the TV, text data that displays the price of the TV, and the performance of the TV will be explained. It will store narration voice, etc. In addition, pointer information will be stored in the scenario file. Virtual information constitutes a playback path information to be described later.

The "keyword index information" is table data, which is a file indicating a plurality of keywords and the file name of the scenario corresponding thereto. For example, in an application that stores a catalog of electric appliances, for a certain scenario file name, "TV" is a keyword for each item, "100,000 yen level" is a keyword for each price, and "Matsushita Electric" is a keyword for each manufacturer. One keyword is associated.

The "search scenario" is a type of scenario and refers to a scenario having a method of designating and presenting a plurality of keywords as search conditions and material information representing a selection box for displaying a list of them. FIG. 3A shows the data format of the search scenario. The difference from the general scenario shown in FIG. 2 is that the material information to be stored has a search material. In the material information of the search material, the "material type" is "search" as shown in FIG. 7B, and the material file name is a file name in which a keyword group is stored as text data. For example, for the search scenario, a selection box for displaying a list of keyword groups is displayed as in the scenario display screen as shown in FIG.

The "modification scenario" is a type of scenario, and is the same as the data format shown in FIG. 2A, but the recorded contents are the display contents of all the scenarios of the search result by a certain keyword. Is characterized in that it is information that modifies. For example, in an application that contains a catalog of electrical appliances, search results such as "The following TVs can be provided by us" are used as information that qualifies all search results by the keyword "TV". Prior to the display of, the opening narration that introduces the contents (video information of the clerk displayed with it) and the ending narration such as "Is there a TV that suits your wishes?" The image information of the clerk displayed together with it) is recorded as a modification scenario.

"Synthesis scenario" is "modification scenario"
It is similar to the point that each material to be recorded modifies the display contents of all scenarios of the search result by a certain keyword, but unlike the "scenario for modification", it is combined with the search result and output. The feature is that it is background information. For example, in an application that stores a catalog of electric appliances, it is meaningful to output still images of the kitchen landscape or the search results at the same time as the background information that modifies all the search results using the keyword "refrigerator". As narration voice, narration and BGM of product introduction for the entire product field specified by keywords such as "For the refrigerator we are currently providing, for large capacity 4 or more families ..." are recorded Will be done.

The "catalog information" is a file that defines a presentation method for reproducing all scenarios that are the search results of a certain keyword together with a plurality of modification scenarios. "Catalog information" consists of "catalog No.", "qualification scenario specification information", "playback order information", and "composite scenario specification information". FIG. 4A shows a data format of catalog information. In FIG. 9A, the catalog No. is also a file name, and a unique number for identifying the catalog is stored. The qualified scenario specification information stores a plurality of scenario numbers that identify qualified scenarios. The reproduction order information further includes modification scenario reproduction order information and search result reproduction order. The modification scenario reproduction order information indicates the reproduction order at the time of reproduction of each modification scenario specified by the modification scenario specification information. The search result playback order indicates an interrupt playback order for interrupting and playing back all scenarios that are search results during playback of the modification scenario. For example, as a search result, scenario A1 and scenario A
2, the scenario A3 is acquired, the search result reproduction order information is 3, the modification scenario reproduction order information is shown as the reproduction order 1 is the scenario B2, the reproduction order 2 is the scenario B1, and the reproduction order 3 is the scenario B3. To do. In this case, FIG.
As shown in (c), scenario B2 is reproduced as reproduction order 1, and then scenario B1 is reproduced as reproduction order 2. Since the reproduction order 3 is the interruption reproduction order of the search results, the scenario A1, the scenario A2, and the scenario A3 are reproduced in the ascending order of the scenario No. after the scenario B1. Then, the scenario B3 is reproduced. The scenario specification information for composition stores one scenario number as a scenario for composition.

The "catalog index information" is table data, and indicates the correspondence relationship between the keyword of each scenario and the corresponding catalog information. "Catalog classification information"
Is information that is obtained by classifying the catalog information in search scenario units. "Catalog index information" and "catalog classification information" are stored in the same file. FIG. 5 (a)
Shows the data format of this file. In the figure,
A keyword that has a correspondence relationship, a catalog number that identifies catalog information, and a scenario N that identifies a search scenario
o. and form table data as one entry. In the example shown in FIG. 5B, three pieces of catalog information of catalogs Z1a, Z1b, and Z1c correspond to the keyword “TV”, and each piece of catalog information corresponds to search scenarios S1, S2, and S3, respectively. It corresponds. This is because the catalog when the keyword "TV" is selected in the search scenario S1 is Z1a, the catalog information when the keyword "TV" is selected in the search scenario S2 is Z1b, and the search scenario S3.
Indicates that the catalog information is Z1c when the keyword "TV" is selected in. Even with the same keyword, the data format allows catalog information to be different for each search scenario. Of course, if the catalog information does not need to correspond to the search scenario, Z1a and Z1
1b and Z1c may be the same.

As described above, the "playback path information" is virtual information formed by collecting pointer information of each scenario, and defines a playback order including a scenario branch including a plurality of search scenarios. . FIG. 6A shows an example of the data format of the reproduction path information, and FIG. 6B is an explanatory diagram of the connection relationship of the logical paths. Each pointer information has connection destination information, and the scenario No. indicates the scenario to be reproduced next to the scenario indicated by the connection source. If there is a branch, there are entries indicating multiple connection destinations for the same connection source scenario. In this case, each entry has branch destination determination information. The branch destination determination information is information for determining the branch destination selection by the user at the branch point of the reproduction path. Specifically, the material number for identifying the material included in the scenario in which the pointer information is stored is stored as the information for determining the branch destination selection. If these materials are used as button image data, these button images will be displayed when a scenario having a branch is reproduced. For this reason, if the user specifies any button as a progress control request using the input means described later, the connection destination scenario in which the material of the specified button is the branch destination determination information is determined as the branch destination. You can

The take-out unit 12 is a drive unit for the recording unit 11 and reads out the data of the recording unit 11 corresponding to the designated file name and outputs it as digital data. The holding / synthesizing unit 13 has a built-in memory for holding digital data, stores and holds the digital data of the material information that is input when a holding command is input from the outside, and stores the input material when there is no holding command. Output information as is. Further, if there is a synthesizing command from the outside, the holding / synthesizing unit 13 reads and outputs the held material information in addition to the inputted material information. Since the held material information is output when the reproduction is performed according to the composition scenario, the material information specified by the composition scenario is stored. Also, since the synthesis command is input after the search result scenario is being reproduced, the synthesis command is synthesized with the search result scenario.

The reproduction output unit 14 internally has a plurality of processing channels for audio information and a plurality of processing channels for video information, and processes and outputs a plurality of audio information and video information in parallel. In the audio processing channel, each input digital data string is converted into an analog audio signal by a predetermined process. The analog audio signals output from the plurality of audio processing channels are mixed with other analog audio signals in the final stage, converted into stereo audio signals, and sent to an attached speaker device (not shown) for audio output. In the video processing channel, the digital data string input to each video channel has a built-in VRAM (Video RA).
M) is written while being overlapped with each other, is read in a unit of one screen, is converted into an analog video signal, and is output as a video from an attached monitor device (not shown). Also, processing channel allocation and output timing for each material information,
If the material information is video information, the display position on the screen and the order of overlap writing to the VRAM are determined by an instruction from a control signal from the outside.

The input unit 15 receives a progress control request and a keyword specification request from the user via an attached input device. The progress control request is a request for the user to select the next or next scene or the branch in the electronic book application. The keyword specification request is a request to specify one of the keyword groups displayed in the selection box presented by the search scenario.

The search unit 16 is composed of a CPU, a memory for operation, and an operation program thereof. When a keyword is designated, the keyword index information is read out through the retrieval unit 12, and this is searched to find the designated keyword. The search result data composed of the identifiers of all the corresponding scenarios is output. The catalog determination unit 17 is composed of a CPU, a memory for operation, and its operation program. When a keyword is designated, the catalog index information and the catalog classification information are read out via the extraction unit 12, and the search source is searched according to the catalog classification information. All catalog information corresponding to the usage scenario is extracted, catalog information corresponding to the keyword of the search condition is determined from the extracted catalog information according to the catalog index information, and the determined catalog information is retrieved via the retrieval unit 12. Output.

The control unit 18 is composed of a CPU, a memory for operation, and an operation program therefor. FIG. 1B is a block diagram showing a detailed configuration of the control unit 18. As shown in the figure, the control unit 18 includes a management unit 181, a reproduction control unit 182, a search reproduction control unit 183, a catalog reproduction control unit 184, a search result holding unit 185, and a catalog holding unit 186. Each component will be described with reference to the flowchart of the control unit 18 shown in FIG.

The management unit 181 performs an initialization operation and a reproduction scenario determination operation. Regarding the initialization operation, when the reproduction is started when the power is turned on, a scenario whose file name is determined as an initialization scenario file is taken out via the taking-out unit 12 (steps 2 to 3). If the retrieved scenario stores search-type material information, this scenario is determined as a search scenario and the search / playback control unit 18
3 is started, and if it is not a search scenario, the reproduction control unit 1
82 is started (step 5). Regarding the operation at the time of starting other than initialization, the scenario of the progress destination is determined according to the pointer information of the scenario for which the reproduction is completed and the progress control request received by the input unit 15 Through the retrieval (steps 1 and 4), it is determined whether it is a search scenario as in the initialization operation. If it is a search scenario, the search playback control unit 183 is activated, and if it is not a search scenario, playback control is performed. The unit 182 is activated. (Step 5) The reproduction control unit 182 is the management unit 1.
According to the scenario designated by 81, the extracting unit 12 obtains control for reproducing and outputting a plurality of material data designated by the scenario at the layout designated by the scenario and the presentation timing.
And the reproduction output unit 14. When the reproduction of the scenario is completed, the management unit 181 is activated. (Step 6) According to the search scenario specified by the management unit 181, the search / reproduction control unit 183 reproduces and outputs the control for reproducing and outputting the keyword group file specified by the scenario at the specified layout and presentation timing. (Step 7). The search / playback control unit 183 determines one keyword from the keyword group as a search condition keyword in accordance with the keyword designation request accepted by the input unit 15 (step 8), and causes the search unit 16 to search to obtain search result data. (Step 9) This is output to and held in the search result holding unit 185. The search / playback control unit 183 that has acquired the search result data causes the catalog determination unit 17 to search for the search condition keyword, acquires the catalog information (step 10), and outputs it to the catalog holding unit 186 to hold it. When the acquisition of the catalog information and the search result data is completed, the search / reproduction control unit 183 activates the catalog reproduction control unit 184.

The search result holding unit 185 is a search / playback control unit 1.
The search result data input from 83 is held. The catalog holding unit 186 holds the catalog information input by the search / playback control unit 183. The catalog reproduction control unit 184 retrieves the search result data and the catalog information from the search result holding unit 185 and the catalog holding unit 186, determines a plurality of scenarios as the modifying scenarios according to the catalog information (step 11), and modifies these modifying scenarios and searches. A reproduction path for reproducing all the scenarios included in the result data is determined according to the catalog information and held as reproduction path data of the search result (step 12). Catalog reproduction control unit 184
Determines a scenario to be reproduced according to the search result reproduction path data (step 13), and if the scenario to be reproduced is a modification scenario, reproduces and outputs a plurality of material data specified by the scenario at the layout and presentation timing specified by the scenario. The control to perform is performed on the extraction unit 12 and the reproduction output unit 14 (step 16). When the scenario to be reproduced is the scenario of the search result, it is confirmed whether or not the material data of the composition scenario is retained in the retaining composition section 13 (step 17), and if not, the catalog information specifies. The composition scenario is retrieved via the retrieval unit 12, the material data designated by the composition scenario is retrieved via the retrieval unit 12, and this is held in the retaining / combining unit 13 (step 18). When the storage of the material data of the composition scenario is completed, the catalog reproduction control unit 184 outputs a composition command to the composition composition unit 13, and the composition reproduction and output of the material composition and the material data specified by the scenario of the search result are composited. A take-out unit 12, a holding and combining unit 13, and a reproduction output unit 1
4 (steps 19 and 20). Specifically, with regard to the image data, for the image data, the scenario for the synthesis is used as background information, and the scenario for the search result is overwritten on the material data specified by the scenario for the image display. . The audio data will be mixed and output. When the reproduction according to the search result reproduction path data is completed, the catalog reproduction control unit 184
Releases the combining instruction to the holding combining unit 13 and releases the combining instruction to the management unit 18.
Start 1

The operation of the information reproducing apparatus configured as described above will be described below (FIG. 1). First, the operation of reproducing and outputting the scenario will be described. When an initialization operation such as power-on is performed, the control unit 18 performs the initialization operation, reads a scenario whose file name is determined as a scenario for initialization from the recording unit 11 through the extraction unit 12, and extracts the scenario. According to the scenario, the material data to be reproduced and the presentation method are determined, and a control signal is output to the extraction unit 12 and the reproduction output unit 14 to cause reproduction output. The extraction unit 12 to which the control signal is input from the control unit 18 reads the specified material file from the recording unit 11 and outputs it to the holding and combining unit 13 as digital data for each material data. Since the holding / synthesizing unit 13 to which the material data is input does not have a holding instruction, the input / outputting material data is output to the reproduction output unit 14 without being held. The reproduction output unit 14 to which a plurality of material data is input determines the layout and output timing of each material data on the display screen according to the control signal, outputs video information from the attached display device, and outputs audio information. Audio is output from the attached speaker device. When the reproduction and output of the initialization scenario is completed, the search unit 16 determines the scenario to be reproduced next according to the progress control request accepted by the input unit 15 and the pointer information of the completed reproduction scenario, and retrieves and reproduces the scenario. The same operation is repeated.

Next, a search operation and a search result reproducing operation will be described. When the scenario to be reproduced is the search scenario, the control unit 18 determines the search condition according to the keyword designation command from the input unit 15, causes the search unit 16 to search the keyword of the search condition, and obtains the search result data. ,
The keyword of the search condition is output to the catalog determination unit 17, the catalog information is acquired from the catalog determination unit 17, the reproduction order of the search result and the modification scenario is determined based on the acquired search result data and the catalog information, and the retrieval is performed. Part 1
2 and the reproduction output unit 14 to perform reproduction output according to the reproduction order.

Further, if the catalog information specifies the composition scenario, the control unit 18 extracts the composition scenario via the extraction unit 12 when the reproduction order of the search result comes. The control unit 18 that has extracted the composition scenario instructs the extraction unit 12 to extract the material data specified by the composition scenario and outputs a holding command to the holding composition unit 13 in accordance with the composition scenario. When the material data of the synthesizing scenario is input from the extracting unit 12, the holding / combining unit 13 holds the holding command because there is a holding command. Control unit 1
No. 8 is when the material data of the composition scenario is completed.
The retrieval result scenario is retrieved from the retrieval unit 12, and the reproduction of the material data of the retrieval result scenario is retrieved from the retrieval unit 12.
Then, the reproduction output unit 14 is instructed, and a synthesis command is output to the holding synthesis unit 13. The material data of the scenario of the search result output from the extraction unit 12 is input to the holding / synthesizing unit 13, and the holding / synthesizing unit 13 adds the plurality of held material data because there is a combining instruction in addition to the input material data. Output. The reproduction output unit 14, to which the material data of the composition scenario and the material data of the search result are input, composites and outputs them. Thereafter, similar synthesis processing is performed for reproduction of all search result scenarios, and when reproduction of all search result scenarios is completed, the control unit 18 instructs the holding synthesis unit 13 to cancel the synthesis command.

As described above, according to the information reproducing apparatus, a plurality of modifying scenarios different for each search condition keyword can be reproduced and output before and after the scenario of the search result, and the user can search the scenario of the search result and the search condition. It is possible to recognize the correspondence relationship of. Further, different combining scenarios can be combined and reproduced and output for each scenario keyword of the search result, and the user can always confirm the correspondence between the scenario of the search result and the search condition during the reproduction of the search result.

Further, the catalog information which defines the method of presenting the continuous reproduction of the scenario of the search result corresponding to the keyword of the search condition can be changed for each search scenario according to the catalog classification information, and the same keyword can be given to the user. Even in the case of search by, search results can be presented with different catalog information for each scenario in which the search is performed. For example, in an electronic product catalog application, the contents are "
In the case of being divided into "family" and "young", even if the search is performed with the same keyword, the search from "family" content and the search from "young" content
It is possible to switch the modifier scenario that modifies the search results, output the video information that the family watches TV for "for family", and output the video information that the TV is viewed outdoors for "young" as the modification scenario. it can. Therefore, during continuous reproduction of the search results, the user can understand from which position on the reproduction path the display caused by the search is.

In the above embodiment, the information recording medium is a CD-ROM, but any other medium such as an IC card, a magnetic optical disk, a phase change optical disk can be used. In particular, in the case of the DVD (Digital Video Disc) standard of a phase change type optical disc,
Since the moving image information is recorded, when a search is performed on these moving image scenes as a search target, there is a problem that the time for continuously reproducing the search results becomes long. Therefore, the present invention, which is capable of clearly presenting the correspondence with the search condition to the user while displaying the search result, is extremely effective.
