Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram illustrating the configuration of the communication system 1. In the figure, the streaming server 10 has a function of streaming and distributing multimedia data composed of moving image data and audio data to the mobile phone 50 via the Internet 30 and the mobile packet communication network 40. This streaming server 10 stores electronic learning data for e-learning (hereinafter referred to as “teaching data 20”) as multimedia data to be provided to the mobile phone 50. Although the data structure of the learning material data 20 will be described in detail later, the streaming server 10 stores, as the learning material data 20, for example, learning teaching material data for managers and sales staff. The learning material data 20 may be learning material data for language learning or learning material data for each subject such as Japanese language, arithmetic, science, and the like.

  The mobile packet communication network 40 includes a gateway server 41 and a base station 42. The gateway server 41 performs mutual conversion between a communication protocol for the mobile packet communication network 40 and TCP / IP used in the Internet 30. A large number of base stations 42 are installed in the communication service area of the mobile packet communication network 40, and perform wireless communication with the mobile phone 50 located in the wireless cell covered by the own station 42.

  The mobile phone 50 is, for example, FOMA (registered trademark) manufactured by NTT Docomo (registered trademark), and has a function of receiving the teaching material data 20 distributed from the streaming server 10 and reproducing it. . With this function, the teaching material data 20 is reproduced on the mobile phone 50, and the user performs e-learning by viewing video and audio based on the reproduced teaching material data 20.

  The streaming server 10 may be provided in the mobile packet communication network 40. Further, the teaching material data 20 may be distributed using a Web server instead of the streaming server 10. The teaching material data 20 is transmitted to the mobile phone 50 by using a general content distribution method in which the teaching material data 20 cannot be reproduced until the teaching material data 20 is completely received. May be.

  FIG. 2 is a diagram for explaining the configuration of the teaching material data 20. As shown in the figure, the teaching material data 20 is divided into major categories such as Chapter 1, Chapter 2,..., And for each chapter, “1-1” item, “1-2” item, etc. It is classified by the small classification. For example, when the user acquires the teaching material data 20 from the streaming server 10, only a part of the teaching material data 20 is downloaded to the mobile phone 50 in units of “chapter” or “item” and reproduced. be able to. The teaching material data 20 is roughly composed of moving image data 21 and audio data 22.

  The moving image data 21 is generated by appropriately combining moving image part data such as the background part 211, the keyword part 212, the key point mark part 213, etc. by editing work. The background part 211 is, for example, individual still image data 211a constituting a background moving image as shown in FIG. When the e-learning is performed by reproducing the teaching material data 20, the keyword part 212, for example, gradually enlarges or blinks a word or sentence that is particularly important for learning, or from the right end to the left end of the screen. This is moving image data for emphasizing and displaying keywords such as moving and displaying. Note that the color and size of the characters in the keyword part 212 are appropriately determined to be conspicuous colors and sizes in consideration of balance with the background and the like. Of course, the display mode (enlarged display, blinking display, moving display, etc.) of the keyword part 212 is the same, and is determined appropriately in consideration of the balance with the background. The key point mark part 213 is image data such as a mark indicating a miniature light bulb or a “!” Mark, and is displayed, for example, immediately before the scene where the above-described keyword part 212 is displayed, and is particularly important for learning. It is used to make a user recognize a word or a sentence with certainty.

  In the case of the mobile phone 50, since the image processing capability is inferior to that of a stationary personal computer or the like, a plurality of types of still images 211a of a person such as a shadow illustrated in FIG. When the images are displayed while being sequentially switched, the capacity of the moving image data 21 can be reduced and the processing load required for reproduction can be reduced. Further, by using the keyword part 212, it becomes possible to emphasize and display a word or one sentence that is particularly important for learning, and further, by using the main point mark part 213, a scene where the main points of the content to be learned are learned. Can be notified to the user, so that the user can firmly learn the essential points. In addition to this, since the moving image is used, the learning content is easy to understand. From the above, e-learning, for example, when using only still images without using moving images, or compared with teaching material data that simply displays a document (text data) indicating the learning content on the screen The learning effect can be enhanced.

  Next, the audio data 22 is generated by appropriately combining audio part data such as a narration part 221, a sound effect part 222, a BGM (Back Ground Music) part 223, etc. by editing work. The narration part 221 is audio data that explains the content to be learned. In the case of the mobile phone 50, since e-learning may be performed in a relatively noisy environment, for example, the owner of a clear voice with a relatively low sound so that the narration can be easily heard in such an environment. Is used as a narrator to record narration. Of course, correction processing for clarifying the sound may be performed after recording the narration. The sound effect based on the sound effect part 222 is output at the same time as the display of the keyword part 212 and the main point mark part 213, for example, so that the user can surely recognize words or one sentence that are particularly important for learning. Used.

  As described above, by using the moving image data 21 and the audio data 22 in combination, the user can perform e-learning using both visual and auditory senses, and thus the e-learning learning effect can be enhanced. Although not shown in FIG. 2, the learning material data 20 includes text data indicating the contents read out by the narration. This text data is appropriately referred to when the user wants to confirm the contents read out by the narration. In addition, each moving image part data such as the background part 211, the keyword part 212, and the main point mark part 213, and each voice part data such as the narration part 221, the sound effect part 222, and the BGM part 223 have unique identifiers. Assigned.

  FIG. 4 is a block diagram illustrating a hardware configuration of the editing device 60 that edits the teaching material data 20. In the figure, a CPU 601 controls each unit of the editing device 60 by executing a program stored in a ROM 602 or an HD (hard disk) 608. The RAM 603 is used as a work area for the CPU 601. The communication interface 604 controls communication performed with the streaming server 10 and the like under the control of the CPU 601. The operation unit 605 is a keyboard, a mouse, or the like, and the display unit 606 is a CRT, LCD, or the like. The audio playback unit 607 includes an amplifier and a speaker, and outputs narration, sound effects, and BGM.

  The HD 608 stores individual moving image part data such as the background part 211, the keyword part 212, and the point mark part 213, and individual audio part data such as the narration part 221, the sound effect part 222, and the BGM part 223. The HD 608 stores application software for editing the moving image data 21 and the audio data 22 constituting the teaching material data 20. The application software is activated, and the moving image data 21 and the audio data 22 are edited by appropriately combining the moving image part data and the audio part data stored in the HD 608, and the teaching material data 20 is generated.

  In addition, the HD 608 includes, for the teaching material data 20 edited using the above-described application software, the playback start timing of each moving image part data and audio part data, the display position of the keyword part 212 and the main mark part 213, and each audio part. The editing data 608a in which the volume of data is recorded is stored. The editing device 60 sequentially reproduces the corresponding moving image part data and audio part data in accordance with the editing data 608a, and generates teaching material data 20 by recording and recording the data. Then, the teaching material data 20 generated in this way is transferred to the streaming server 10 and distributed to the mobile phone 50 by the streaming server 10. Further, the editing device 60 corrects the teaching material data 20 such as correcting a part of the teaching material data 20 or adding new data by correcting the contents of the editing data 608a.

  The editing device 60 includes a recording medium drive, records the generated teaching material data 20 on a recording medium such as a CD-ROM, and stores the teaching material data 20 in the streaming server 10 via the recording medium. Also good. In addition, the editing device 60 includes, for example, an editing device that edits the moving image data 21 and an editing device that edits the audio data 22 as separate devices, or includes moving image part data, audio part data, and editing data. The editing system may include a plurality of devices, such as a storage device that stores 608a provided separately from the editing device 60.

  Next, FIG. 5 is a sequence chart illustrating the operation of each unit of the communication system 1. First, various video part data and audio part data necessary for generating the teaching material data 20 are generated and stored in the HD 608 of the editing device 60 (step S101). Here, for example, various animation parts data such as the background part 211, the keyword part 212, and the key mark part 213 are requested to be created by an animation or computer graphics production company, and the completed data is stored in the HD 608 of the editing device 60. can do. Similarly, various audio parts data such as the narration part 221, the sound effect part 222, and the BGM part 223 are requested to be created by a production company such as narration, sound effect, and BGM, and the completed data is sent to the HD 608 of the editing device 60. Can be stored.

  Next, editing application software is activated in the editing device 60 (step S102), and editing processing of the teaching material data 20 is performed (step S103). In this editing process, the following items are determined for the teaching material data 20, for example, for each “item” described above, the moving image part data and audio part data to be used are selected.

(1) Selection of the background part 211 to be used and setting of the reproduction start timing and reproduction end timing of each selected background part 211.
(2) Selection of the keyword part 212 to be used and setting of the playback start timing, playback end timing, display position, and the like.
(3) Selection of key mark parts 213 to be used and setting of the reproduction start timing, reproduction end timing, display position, and the like.
(4) Selection of the narration part 221 to be used and setting of the playback volume and playback start timing.
(5) Selection of the sound effect part 222 to be used and setting of the playback volume and playback start timing.
(6) Selection of the BGM part 223 to be used and setting of the playback volume and playback start timing.

  The items (1) to (6) described above can be adjusted by the editing device 60 while appropriately reproducing the selected moving image part data and audio part data. When the editing operation of the teaching material data 20 is completed in this way, first, the editing device 60 creates editing data 608a in which the items (1) to (6) are recorded for the edited teaching material data 20. And stored in the HD 608 (step S104). Next, the editing device 60 sequentially reproduces the corresponding moving image part data and audio part data in accordance with the created editing data 608a, and generates teaching material data 20 by recording and recording the data (step S105). Then, the editing device 60 transfers the generated teaching material data 20 to the streaming server 10 (step S106).

  The streaming server 10 stores the learning material data 20 received from the editing device 60 (step S107), and transmits the learning material data 20 to the mobile phone 50 in response to a request from the mobile phone 50 (step S108). When the mobile phone 50 receives the teaching material data 20 from the streaming server 10, it reproduces it (step S109). In this way, the teaching material data 20 is reproduced on the mobile phone 50, and the user performs e-learning by viewing video and audio based on the reproduced teaching material data 20. As described above, the teaching material data 20 is divided into “chapter” and “item”, and when the user acquires the teaching material data 20 from the streaming server 10, the “teacher” or “item” unit is used. Only a part of the teaching material data 20 can be downloaded to the mobile phone 50 and reproduced.

  The HD 608 of the editing device 60 stores editing data 608a in which the reproduction data of each moving image part data and each audio part data constituting the learning material data 20 is recorded. Therefore, for example, in the case where new learning content is added to a part of the teaching material data 20 that has already been generated, audio part data or moving image part data is created only for the part to be added, and the editing device 60 After being stored in the HD 608, the editing application software is started, and only a part of the contents of the editing data 608a is rewritten using newly added audio part data or moving image part data. Teaching material data 20 incorporating new learning contents can be generated. Further, when the teaching material data 20 that has already been generated is modified so that a part of the content is deleted, the editing device 60 edits information about the video part data and audio part data that are no longer necessary. Only by deleting from the data 608a, the teaching material data 20 from which a part of the data is deleted can be generated based on the editing data 608a. By correcting the contents of the editing data 608a in this way, it is possible to easily modify the teaching material data 20, such as correcting a part of the teaching material data 20 or adding new data.

6 to 9 are screen display examples in the mobile phone 50.
When the teaching material data 20 is reproduced on the mobile phone 50, first, a header image as shown in FIG. 6 is displayed. Note that the character string “sales store version” and the character string “conflict processing” in the heading image shown in the figure are also the keyword parts 212, and these character strings are gradually enlarged and displayed as time elapses, for example. Or gradually change the color of the characters. After such a headline image is displayed, narration and BGM output are started, and e-learning using the mobile phone 50 is started.

  Then, when reaching a scene where important matters are learned (point learning scene), for example, as shown in FIG. 7, a point mark part 213 composed of a miniature bulb pattern and a character string “POINT !!” is displayed on the screen. And a sound effect (notification sound) for notifying that the scene where the main point is to be learned has been visited is output. After that, a keyword part 212 “The conflict between subordinates gathers related parties” is displayed. Displayed on the screen. In addition, a red line having a predetermined width is displayed behind the character string, so that the user can reliably recognize the phrase “the conflict between subordinates gathers related parties”.

  FIG. 8 is an example of a screen display when a different point learning scene is reached, and a “!” Mark is displayed as the point mark part 213 together with an output of a sound effect that notifies that the scene to learn the point has come. After that, a keyword part 212 with “question power” which is an important keyword for learning is displayed. A yellow line having a predetermined width is also displayed behind the character string so that the user can reliably recognize the word “question”. Further, the keyword parts 212 displayed in FIGS. 7 and 8 are not only displayed, but, for example, are gradually enlarged, displayed moved from the right end to the left end of the screen, or displayed behind. The display mode can be varied with the passage of time, such as the line color and width changing.

  Also, as shown in FIG. 9, along with the output of the sound effect, first, the character string “motivation method” is displayed at the top of the screen, and then the character string “consider and execute” is considered. Execute while = "Motivation", Character string "Think while executing = Motivation", Character string "Think after execution = Motivation" are displayed one line at a time, and are important keywords for learning By repeatedly displaying “motivation” with specific practical methods, it is possible to make the user learn the keyword and information related to the keyword firmly.

  As described above, the moving image data 21 constituting the teaching material data 20 includes word image data (keyword part 212) indicating the main points of the contents to be learned and mark image data for notifying that a scene where the main points are to be learned has been visited. (Main point mark parts 213) are included. The sound data 22 constituting the teaching material data 20 includes notification sound data (sound effect parts 222) for notifying that a scene where the main point is learned has come.

  Therefore, according to the present embodiment, a word or a sentence indicating the main point of the content to be learned is displayed as a moving image, and the user is notified that the scene where the main point is to be learned has been reached by displaying a mark or outputting a sound effect. The Therefore, words and sentences that are particularly important for learning can be highlighted and displayed, and the user can be notified that the scene where the key points have been learned has been visited. Can do. In addition to this, the moving image data 21 and the audio data 22 are used in combination, and the user is allowed to perform e-learning using both visual and auditory senses, so that the learning content is easy to understand. As described above, the learning effect of e-learning is compared with the case where only still images are used without using moving images, or compared with teaching material data in which a document (text data) indicating learning content is simply displayed on the screen. Can be enhanced.

  Further, the editing device 60 creates editing data 608a in which the playback conditions of the moving image part data and audio part data constituting the teaching material data 20 are recorded and stored in the HD 608, and the corresponding moving image part data and audio corresponding to the editing data 608a are created. The teaching material data 20 is generated by recording and recording the part data while sequentially reproducing the part data. Accordingly, by correcting the contents of the editing data 608a stored in the HD 608, a part of the teaching material data 20 can be corrected or new data can be added, so that the editing work of the editing data 608a can be easily performed. .
