Description

  The present invention is an apparatus that receives and reproduces video, and efficiently accumulates information such as news so that it can be efficiently reproduced according to a viewer's request.

  In digital broadcasting, program scheduling information that composes EPG (Electric Program Guide) information and scenes included in the program are multiplexed with the main body of the program, such as video and audio data, and the scene time position It is possible to send index information and the like defined by designating, and various services are considered using such characteristics of digital broadcasting.

  For example, according to NHK's ISDB (Integrated Service Digital Broadcasting) “Anytime News” function, when a news program is recorded and played back, the user can select and view the specific news of their choice. A method has been developed. In this method, it is determined in what time zone a scene corresponding to specific news included in a news program (in this specification, each specific news is referred to as an “article”) is broadcast. The index information shown is multiplexed and broadcast on the video / audio data of the news program, and the receiving side stores this index information together with the video / audio data of the news program. This index information can be described by a program index encoding method that is being standardized in C digital broadcasting. At the time of reproduction, a list of articles is displayed on the screen based on the index information, and the article selected by the user is reproduced from there.

  Also, Japanese Patent Laid-Open No. 2000-287138 “Broadcasting System, Information Reference Method and Receiving Device” relates to the provision of a broadcasting system that can efficiently reproduce and view information such as news programs. In a broadcast system in which a scene transmitted from a transmission apparatus is stored and reproduced by a reception apparatus, the transmission apparatus transmits an update attribute of the scene as management information of the scene to be broadcast. In the receiving device, when a replacement scene is received for a scene whose update attribute is a replacement from among the stored scenes, the scene is replaced, and related information in the stored scene is identified, They are presented in response to user requests.

  In Japanese Patent Laid-Open No. 2000-115165 “Transmitting Device and Transmitting Method, Receiving Device and Receiving Method, and Transmitting and Receiving Device and Transmitting and Receiving Method”, when the content registered in the content DB is updated at the broadcasting station, the update is performed. Data to be transmitted is transmitted via the broadcast network. On the other hand, the receiving terminal has proposed a method in which the content is updated.

  However, with this method, there is only one index information for one news program broadcast at a specific time, and the relationship between multiple articles cannot be handled across news programs. . That is, it is only possible to select and reproduce an article from one accumulated news program, and when the news program is accumulated over a plurality of times, the reproduction and viewing cannot be performed efficiently. .

  For example, in the case of news about a murder case, if one broadcaster talked in detail about the criminal motivation part, another broadcaster talked in detail about the background part of the case, two broadcasts were needed to capture the whole picture of the case. You need to watch the news from the station. Conversely, if you only want to pinpoint the contents of the incident, there is no need for detailed parts, which hinders efficient viewing.

  In addition, viewers are required to have the ability to accurately determine media information such as television, radio, and computers. As a video sender, it is necessary to get viewers to understand the intention of the program, and to have various ways of reading including criticism. In other words, it is indispensable for viewers to develop and possess “media literacy” ability to critically read and interpret information, and to transmit information by themselves using various media. Each broadcasting station or the like has a subjective point in the transmitted video by editing or the like. Viewers are required to understand these subjective differences.

  The present invention solves such a conventional problem, and efficiently stores broadcast information such as a news program and enables efficient playback and viewing according to a user's request, and a receiving apparatus thereof. And is intended to be used as a tool to develop media literacy skills.

  In order to solve the above-described problems, a program according to the present invention causes a computer to receive and play a video to obtain means for obtaining a scene for an article, means for obtaining information on an entity appearing in the scene, and information on the entity.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

(First embodiment)
It is assumed that the video reception / playback apparatus according to the first embodiment operates in the following broadcasting system environment. That is, as shown in FIG. 1, one or a plurality of broadcast transmission devices 100, 110..., Terrestrial broadcast, satellite broadcast, CATV, Internet, or other transmission means 300, and a video reception / reproduction device 200 that receives and reproduces the broadcast. is there. The sending devices 100, 110... Are a video sending means 11 for generating / sending program video / audio data, a program index sending means 12 for generating / sending a program index, and a multiplexer for multiplexing the data output from each means. 13 and a modulator 14 that modulates a signal output from the multiplexer 13.

  In addition, the video reception / playback apparatus 200 includes a reception unit 21 that receives a reception signal such as a broadcast wave, a separation unit 22 that separates video / audio data and a program index from the multiplexed reception signal, and a video / audio data. Reproducing means 23 for decoding, presentation means 24 comprising a speaker or CRT, additional information obtaining means 25 for obtaining a program index, accumulating means 26 for accumulating video / audio data and additional information, and a CPU 27 for controlling each part A memory 28 used for the work area of the CPU 27 and an input means 29 such as a keyboard and a mouse are provided.

  In this broadcasting system, the video sending means 11 of the sending devices 100, 110... Outputs the video / audio data of the program to the multiplexer 14, and the program index sending means 12 uses the article management information (FIG. 2) described later as the program index. And scene definition information (FIG. 3) and entity definition information (FIG. 4) are generated and output to the multiplexer 13.

  The article management information (FIG. 2) describes an article ID, an article name, and a scene ID string of scenes belonging to the article. For example, in the example in FIG. 2, the article ID 2300 has an article name “Mr. Nonaka and Mr. Suzuki are talking”, and describes that the scene of the article is a scene with scene IDs 250 to 254. It is assumed that there is no overlap between scenes. In this embodiment, for the sake of simplicity, the article ID is assumed to be the same for each broadcast station for the same article, but it is also possible to determine identity based on the article name. is there. As a method for determining the identity of article names, for example, the method described in Japanese Patent Laid-Open No. 2000-287138 “Broadcasting System, Information Reference Method and Receiving Device” is used, but the method is particularly limited in the present invention. is not.

  In the scene definition information (FIG. 3), a scene ID, an entity ID in entity definition information described later, a semantic place name in the scene, and a semantic time in the scene are described. For example, in the example shown in FIG. 3, entities 31 and 32 appear in the scene with scene ID 250, and the scene was recorded at 13:55 on February 20, 2001 at the National Diet Building. Yes.

  The entity definition information (FIG. 4) describes the name of an entity that appears in a scene and the name of the event that the entity is performing. For example, in the example in FIG. 4, the entity ID 31 describes that Mr. Nonaka is in a meeting.

  The program index thus created by the program index sending means 12 is output from the video sending means 11 and multiplexed with the video / audio data by the multiplexer 13, modulated by the modulator 14, and sent by the transmission means 30 to the receiving device. Sent.

  On the other hand, in the receiving device 20, the receiving means 21 receives a received signal such as a broadcast wave, and the separating means 22 separates the multiplexed received signal into video / audio data and a program index. The separated video / audio data is stored in the storage means 26. When real-time viewing is performed, the separated video / audio data is also input to the reproduction means 23, and the decoded video / audio data is displayed from the presentation means 24. The separated program index is acquired by the additional information acquisition unit 25 and stored in the storage unit 26.

  The CPU 27 creates scene accumulation information (FIG. 5) and a scene accumulation list (FIG. 6) of articles accumulated in the accumulation means 26 from the program index acquired by the additional information acquisition means 25 and stores them in the accumulation means 26.

  The scene accumulation information (FIG. 5) describes the article ID of the article to which the scene accumulated in the accumulation means 26 belongs, the scene ID, the file name, and the scene length of the scene. For example, in the example in FIG. 5, the scene with the scene ID 250 in the article ID 2300 is stored as the file name File250.mpg in the storage means 26, and the scene length is 1 minute 25 seconds.

  The scene accumulation list (FIG. 6) describes the correspondence between the scenes accumulated in the accumulation means 26 and the entities appearing in the scenes. The And / Or row is And when the combination of the name, the event name, and the place name in the corresponding column appears in a plurality of articles, and is Or otherwise. In the example of Fig. 6, the entity that Mr. Nonaka is talking to appears in the scene ID 250 of article ID 2300, and because the And / Or line is And, the scene where Mr. Nonaka is also talking to articles with other article IDs Is present. On the other hand, the entity that Mr. Suzuki gets in the car appears only in the scene of the scene ID 251 of the article ID 2300, and the And / Or line is Or, indicating that it does not exist in other articles. Note that in order to determine the degree of matching between scenes at the entity level, if a set of an article ID, a name, an event name, and a place name matches as described later, it is determined that the corresponding scenes match.

  The accumulated scene length information (FIG. 7) describes the scene length of the scene stored in the storage device 26 for the same article ID. In the example shown in FIG. 7, the article with the article ID 2300 is accumulated for 1 minute 00 seconds.

  For example, Yukinobu Taniguchi, Yoshinobu Tonomura, Hiroshi Hamada “Detection Method of Video Shot Switching and Its Application to Video Access Interface”, D.II, Vol.J79-D-II, Although a technique such as No. 4 is used, the present invention is not limited to this technique.

  FIG. 8 is a flowchart showing a procedure for extracting a common scene portion and a different scene portion in the same article for one article transmitted from each broadcasting station. The operation of extracting a common scene portion and a different scene portion in the same article in this apparatus will be described below based on this flowchart.

  First, in step 101, article management information is retrieved based on the ID of the article, and all scene IDs are obtained and stored in the memory 28. In the example shown in FIG. 2, 250, 251, 252, 253, and 254 are obtained as scene IDs for the article with the article ID 2300.

  In step 102, one scene ID is extracted from the memory 28, scene definition information is searched based on the scene ID, and all entity IDs and locations are obtained and stored in the memory 28. In the example shown in FIG. 3, for example, entity IDs 31 and 32 and a place name “National Diet Building” are obtained for the scene ID 250.

  In step 103, one entity ID is extracted from the memory 28, entity definition information is searched based on the entity ID, and a name and an event name are obtained. In the example shown in FIG. 4, for example, the name “Nonaka” and the event name “conversation” are obtained for the entity ID 31.

  In step 104, the article ID, the location, the name, and the event name are compared with those registered in the scene accumulation list shown in FIG. If it exists, go to step 105. If not, the process proceeds to step 106. In the above example, the search is made from the scene accumulation list using the article ID 2300, the place name “National Diet Building”, the name “Nonaka”, and the event name “Conversation” as keys.

  In step 105, And is registered in And / Or of the corresponding column in the scene accumulation list, and the process proceeds to step 107. In the above example, there are columns with the article ID 2300, the place name “National Diet Building”, the name “Nonaka”, and the event name “Conference” as keys, and the And / Or row is And.

  In step 106, the name, the event name, the location, the scene ID, and the article ID are registered as new columns in the table, and Or is registered in And / Or.

In step 107, it is determined whether there is an entity ID that has not been operated in step 103 yet. If there is, return to Step 103.
In step 108, it is determined whether or not there is a scene ID that has not been operated in step 102 yet. If there is, return to Step 102.

  FIG. 9 shows the common part of the scene group obtained by the procedure for extracting the common scene part and the different scene part in the same article for one article transmitted from each broadcasting station described above. It is the flowchart which showed the procedure which ranks according to length and shows to a viewer. The operation of ranking and presenting to the viewer will be described below based on this flowchart.

In step 201, all article IDs are extracted from the scene accumulation information shown in FIG.
In step 202, one article ID extracted in step 201 is extracted, and based on this, the scene accumulation list shown in FIG. 6 is searched, and all scene IDs whose And / Or is And are extracted. For example, for an article ID 2300, 250 is extracted as a scene ID with an article ID 2300 in the example shown in FIG.

  In step 203, one of the scene IDs extracted in step 202 is extracted, and the scene accumulation information shown in FIG. 5 is searched to obtain the scene length. In the example shown in FIG. 6, the scene length for scene ID 250 is 1 minute 25 seconds.

  In step 204, the scene length for the scene ID extracted in step 203 is added to the cumulative scene length of the scene ID in the cumulative scene length information shown in FIG. In the example shown in Fig. 7, the cumulative scene length of article ID 2300 was 1 minute 00 seconds, but with the scene length of scene ID 250 1 minute 25 seconds, 2 minutes 25 seconds as shown in Figure 7-1 It becomes.

  In step 205, it is determined whether or not there is a scene ID that has not been subjected to the operation in step 204 among the scene IDs extracted in step 203. If it still exists, return to step 204. If not, the process moves to step 206.

  In step 206, it is determined whether or not there is a scene ID that has not been subjected to the operation in step 202 among the article IDs extracted in step 201. If it still exists, return to step 202. If not, the process proceeds to step 207.

  In step 207, rearrangement is performed in descending order based on the accumulated scene length obtained in step 204.

  In step 208, based on the result of rearranging in step 207, the article management information shown in FIG. 2 is searched based on the article ID in order from the longest accumulated scene length, and the obtained article name is displayed in the presentation means 24. Present. In the example of FIG. 7A, the article ID 2300 “Mr. Nonaka and Mr. Suzuki have a meeting” and the article ID 2301 “Mr. Doi speaks” are presented on the presentation device 24 as shown in FIG.

(Second embodiment)
The second embodiment is an example in which priority is given to a specific broadcasting station depending on user's preference. The description will focus on the differences from the first embodiment.

  First, information about the broadcasting station is added to the article management information. Article management information (FIG. 10) describes an article ID, an article name, a scene ID string of a scene belonging to the article, and a broadcasting station name. For example, in the example in FIG. 10, the article ID 2300 is an article name “Mr. Nonaka and Mr. Suzuki are talking”, and the scene of the article is a scene with scene IDs 250 to 254, which describes that it is broadcast by TV A. doing. Note that the items regarding the identity between broadcast stations regarding the article ID are the same as in the first embodiment.

  Next, information related to the broadcasting station is added to the scene accumulation information. The scene storage information (FIG. 11) describes the correspondence between the scene stored in the storage means 26, the name of the broadcasting station where the scene was broadcast, and the entities that appear in the scene. The And / Or row is And when the combination of the name and the action in the corresponding column appears in a plurality of articles, and Or otherwise. In the example of Fig. 11, the entity that Mr. Nonaka talks with appears in scene ID 250 of article ID 2300, and because the And / Or line is And, there is a scene where Mr. Nonaka is talking to articles with other article IDs. It indicates that the scene by the broadcasting station having the highest preference ranking “TV A” is selected. On the other hand, the entity that Mr. Suzuki gets in the car appears only in the scene of the scene ID 251 of the article ID 2300, and the And / Or line is Or, indicating that it does not exist in other articles.

  Broadcast station preference information (FIG. 12) is registered by the user of the present apparatus as to the preference of the broadcast station, and includes the name of the user company, the name of the broadcast station, and the degree of preference. In the example in FIG. 12, it is assumed that the degree of preference is a value from plus 100 to minus 100, plus 100 is most preferred and minus 100 is least preferred, and user Fukada likes television A most and then prefers television B. Is described.

  FIG. 13 is a flowchart showing a procedure for a user to register broadcast station preference information. The operation of the user in this apparatus for registering broadcast station preference registration information will be described below based on this flowchart.

  In step 301, the user ID input by the user from the input means 29 is received. FIG. 13-1 is a screen example of the presentation means 24 in this step. This device requests input of user ID and password.

  In step 302, the user ID and password input in the previous step are checked and authenticated. If the authentication is successful, the process proceeds to step 303. If the authentication fails, the process returns to step 301 to prompt the user to input again.

  In step 303, the broadcasting station name is displayed on the presentation means 24. FIG. 13-2 is a screen example of the presenting means 24 in this step. In this example, NHK, C TV, B broadcast, D TV, TV A, and TV B are displayed as broadcast station names.

  In step 304, the user inputs the degree of preference for each broadcasting station name from the input means 29. FIG. 13-3 is a screen example of the presentation means 24 in this step. In this example, it is shown that the preference is in the order of NHK, D TV, TV A, TV B, C TV, and B broadcast.

  In step 305, the user presses the end button.

  In step 306, it is determined whether or not the preference ranking is input in step 304 for all broadcasting stations. If there is no omission, go to Step 307. If there is any omission, the process returns to step 304 to prompt the user to input again.

  In step 307, the broadcast station preference information input by the user in step 304 is registered in the form of broadcast station preference information shown in FIG.

  FIG. 14 is a flowchart showing a procedure for extracting a common scene portion in the same article for one article transmitted from each broadcasting station. The operation of extracting a common scene portion in the same article in this apparatus will be described below based on this flowchart.

  First, in step 401, based on the ID of the article, the article management information is searched to obtain all scene IDs and broadcasting station names, and are stored in the memory 28. In the example shown in FIG. 10, for the article with article ID 2300, 250, 251, 252, 253, and 254 as scene IDs and TV A as the broadcast station name are obtained.

  In step 402, one scene ID is extracted from the memory 28, scene definition information is searched based on the scene ID, all entity IDs and location names are obtained, and stored in the memory 28. In the example shown in FIG. 3, for example, entity IDs 31 and 32 and a place name “National Diet Building” are obtained for the scene ID 250.

  In step 403, one entity ID is extracted from the memory 28, and entity definition information is searched based on the entity ID to obtain a name and an event name. In the example shown in FIG. 11, for example, the name “Nonaka” and the event name “conversation” are obtained for the entity ID 31.

  In step 404, the article ID, the place name, the name, and the event name are compared with those registered in the scene accumulation list. If it exists, go to step 405. If not, the process proceeds to step 406. In the above example, search is made from the scene accumulation list using the article ID 2300, the place name “National Diet Building”, the name “Nonaka”, and the event name “Conversation” as keys.

  In step 405, And is registered in And / Or of the corresponding column in the scene accumulation list, and the process proceeds to step 407. In the above example, there are columns with the article ID 2300, the place name “National Diet Building”, the name “Nonaka”, and the event name “Conversation” as keys, and the And / Or line is And.

  In step 406, broadcast station preference information is searched using the broadcast station name in the corresponding column in the scene accumulation list obtained in step 405 as a key to obtain a preference rank.

  In step 407, broadcast station preference information is searched using the broadcast station name obtained in step 401 as a key to obtain a preference rank.

  In step 408, the preference ranking obtained in step 406 is compared with the preference ranking obtained in step 407. If the preference ranking obtained in step 407 is higher, the process moves to step 409. Otherwise, go to step 111.

  In step 409, the broadcasting station name in the corresponding column in the scene accumulation list is rewritten with the broadcasting station name obtained in step 401.

  In step 410, the name, the event name, the location, the scene ID, the article ID, and the broadcasting station name obtained in step 401 are registered as a new column in the table, and Or is registered in And / Or.

In step 411, it is determined whether there is an entity ID that has not been operated in step 403 yet. If there is, return to Step 403.
In step 412, it is determined whether or not there is a scene ID that has not been operated in step 402 yet. If there is, return to Step 402.

(Third embodiment)
The third embodiment is an example in which priority is given to a specific broadcast station based on the viewing history. The description will focus on the differences from the first and second embodiments.

  In the third embodiment, the cumulative viewing time is added to the broadcast station preference information. The cumulative viewing time is information indicating how much a certain viewer has watched the program of each broadcasting station. In the second embodiment, the user of this apparatus registers the preference of the broadcasting station. However, in this embodiment, this apparatus estimates the preference of the broadcasting station based on the viewing history. Therefore, the broadcast station preference information includes a user ID, a broadcast station name, and a cumulative viewing time. In the example in FIG. 15, the user Fukada describes watching TV A for 12 hours 30 minutes and watching TV B for 11 hours 10 minutes.

  FIG. 16 is a flowchart showing a procedure for recording broadcast station preference information in the present apparatus based on viewing history and estimating and ranking broadcast station preferences. The operation of this apparatus will be described below based on this flowchart.

  In step 501, the user ID input from the input unit 29 by the user is received. FIG. 16-1 is a screen example of the presentation means 24 in this step. This device requests input of user ID and password.

  In step 502, the user ID and password input in the previous step are checked and authenticated. If the authentication is successful, the process proceeds to step 503. If the authentication fails, the process returns to step 501 to prompt the user to input again.

  In step 503, the broadcast station name input by the user from the input means 29 is received. FIG. 16-2 is a screen example of the presentation means 24 in this step. In this example, NHK, D TV, TV A, TV B, C TV, B broadcast, and each broadcast station are selected by channel number. For example, assume that TV B is selected.

  In step 504, based on the broadcasting station selected in step 503, the receiving unit 21 receives the broadcast, the separating unit 22 separates the video / audio data and the program index from the received signal, and the reproducing unit 23 separates the video / audio data. The audio data is decoded, and the actual broadcast program is displayed on the presentation means 24. Now, assuming that TV B is selected in step 503, the TV B program is displayed on the presenting means 24. At the same time, the measurement of viewing time is started.

In step 505, it is confirmed whether or not the user has received a broadcast station change signal or a press of a broadcast end button from the input means 29. If the broadcast station change signal or the broadcast end button is pressed, the process proceeds to step 506. Otherwise, return to Step 504.
In step 506, the measurement of the viewing time started in step 504 is stopped, and the viewing time in step 504 is calculated for the broadcasting station that has been viewed until then. For example, assume that TV B is watched for 1 hour 30 minutes in step 504.

  In step 507, the viewing time calculated in step 506 is added to the viewing time of the broadcast station in the broadcast station preference information shown in FIG. For example, assuming that TV B was watched for 1 hour and 30 minutes in step 504, in the example shown in FIG. 15, since TV B had been viewed for 11 hours and 30 minutes until then, the new cumulative viewing time was 13 hours. It will be 00 minutes.

  In step 508, it is confirmed in the step 505 whether the broadcast station change signal or the broadcast end button is pressed by the user through the input means 29. If it is a broadcast station change signal, the process returns to step 503. If the broadcast end button is pressed, the process proceeds to step 509.

  In step 509, based on the viewing time newly obtained in step 507, each row of the broadcast station preference information is rearranged for each user, ranked in descending order, and stored in the storage means 26. In the example of Step 507, the cumulative viewing time of TV B was 13:00, so the cumulative length of TV A exceeded 12 hours and 30 minutes. As shown in Figure 15-1.

(Fourth embodiment)
The fourth embodiment is an example in which one article transmitted from each broadcasting station is presented by paying attention to a difference portion among a common scene portion and a difference scene portion in the same article. is there. A description will be given centering on differences from the first to third embodiments.

  The presentation list (FIG. 17) describes the file name of the video corresponding to the scene ID to be presented to the viewer, and the name of the broadcasting station where the scene was broadcast. For example, in the example in FIG. 17, the scene ID 251 is a scene broadcast on the television A, the scene ID 252 is a scene broadcast on the television B, and the file names are “File251.mpg” and “File252.mpg”, respectively. The scene ID 250 describes a scene in which And / Or described in the scene accumulation list in FIG. 5 is And, that is, a common scene broadcast by a plurality of broadcasting stations. Therefore, for example, “AND” and a special symbol that do not overlap with the broadcast station name are described in the broadcast station name.

  FIG. 18 is different in the scene group obtained by the procedure for extracting the common scene part and the different scene part in the same article for one article transmitted from each broadcasting station described above. It is the flowchart which showed the procedure which shows a part to a viewer. The operation to be presented to the viewer will be described below based on this flowchart.

  In step 601, all article IDs are extracted from the scene accumulation list shown in FIG.

  In step 602, one article ID extracted in step 601 is extracted, and based on this, the scene accumulation list shown in FIG. 11 is searched, and all scene IDs whose And / Or is And are extracted. For example, for the article ID 2300, 250 is extracted as the scene ID with the article ID 2300 in the example shown in FIG.

  In step 603, the scene accumulation list shown in FIG. 11 is searched based on the article ID extracted in step 602, and all scene IDs and broadcast station names whose And / Or is Or are extracted. For example, for the article ID 2300, in the example shown in FIG. 11A, the scene ID 251 and the broadcast station name “TV A” whose article ID is 2300, and the scene ID 252 and the broadcast station name “TV B” are extracted.

  In step 604, the scene ID extracted in step 602 is added to the presentation list, and the broadcast station name is “AND”. In the example shown in FIG. 11A, the scene ID 250 is added to the presentation list.

  In step 605, the set of scene ID and broadcast station name extracted in step 603 is added to the presentation list. In the example shown in FIG. 11A, the scene ID 251 and the broadcast station name “TV A” scene ID 251 and the broadcast station name “TV B” are added to the presentation list.

  In step 606, the scene accumulation information shown in FIG. 6 is searched based on the article ID and the scene ID, the corresponding file name is extracted, and added to the presentation list. In the example shown in FIGS. 11-1 and 6, the file name “File250.mpg” is assigned to the scene ID 250, the file name “File251.mpg” is assigned to the scene ID 251, and “File 252.mpg” is assigned to the scene ID 252. Join the presentation list.

  In step 607, it is determined whether there is a scene ID that has not been subjected to the operation in step 602 among the article IDs extracted in step 601. If it still exists, the process returns to step 602. If not, the process moves to step 608.

  In step 608, the article management information shown in FIG. 2 is searched based on the article ID, and the obtained article name is presented to the presentation means 24. For example, the article ID 2300 “Mr. Nonaka and Mr. Suzuki have a meeting” and then the article ID 2301 “Mr. Doi speaks” are presented on the presentation device 24 as shown in FIG.

  In step 609, a request for viewing an article by the viewer is received. For example, suppose that an article ID 2300 “Mr. Nonaka and Mr. Suzuki meet” is requested.

  In step 610, based on the viewing request received in step 609, the presentation list generated in steps 602 to 606 is referred to and the corresponding scene is presented to the presentation device 24.
