Then, the attribute information storage unit 12 stores it in the layout database DB1 (step S7).

When the editing server 1 receives a request for creating a synchronous multimedia presentation from the client 2, the editing program generator 11 causes the editing program generator 11 to select a desired one from a plurality of registered layout information. A layout selection screen source is generated, and the input / output unit 15 sends it to the client 2 (step S11).

FIG. 8 is a diagram showing a layout selection screen constituted by the layout selection screen source. On the displayed layout selection screen, a frame imitating a window is displayed according to the number of pieces of layout information, and moreover, a plurality of areas are displayed according to the layout information in each frame, and any one of them can be selected. Has become.

That is, the browser 21 displays the synchronized multimedia presentation in a state where the presentation is not reproduced. Some of them are based on layout information registered by the user and others are based on layout information registered for an unspecified number of users.

When any frame, that is, a layout is selected (step S13), the layout ID of the selected layout is transmitted to the editing server 1 (step S15), and the synchronous multimedia is associated with this layout ID. The presentation of the presentation will be defined (generated).

Next, generation of a presentation reproduced in one area will be described. In creating a presentation, first, a presentation is created in an area in which the editing order is the first (called a main area). The second and subsequent areas (called sub areas)
Also in, the presentation is defined by sequentially defining the clips. Therefore, in order to avoid duplication of description, a method of defining a clip in the sub area when the presentation in the main area is already defined will be described.

In the editing server 1, when a clip editing request is issued from the client 2, the editing program generating section 11
Generates a clip type selection screen source for selecting a clip type, and the input / output unit 15 sends this to the client 2 (step S21). When the clip type is selected from the moving image, still image, text, and audio (step S23), the selected clip type is

9 to 13 are views showing an example of the clip edit screen source. FIG. 14 is a diagram showing a clip edit screen configured by this clip edit screen source and an operation performed in the edit process. More specifically, FIG. 14 shows a state in which a clip reproduced in the sub area is edited on the assumption that the presentation reproduced in the main area is already edited. The clips reproduced in the sub area are clips such as moving images that require materials.

The source of the clip editing screen is the browser 21.
And the various methods are defined by the method definition statement in the script language.

Specifically, a "reproduction method" for reproducing a presentation or the like when a reproduction button (the button object will be described later) is pressed, and a "stop" for stopping the presentation or the like when a pause button or a stop button is pressed. Method ", when the start button is pressed, the" start point acquisition method "that obtains the length of time from the beginning of the material to the point (start point) that was playing when the start button was pressed, when the end button is pressed , "End point acquisition method" to get the length of time from the start point of the material to the point (end point) that was being played when the end button was pressed, from the start point to the end point if the preview button described later was pressed "Preview method" to play back, "Material setting method" to set the material specified in the pull-down menu to the player, insert When the button is pressed, the "insertion point acquisition method" that obtains the length of time from the start point of the presentation to the point (insertion point) that was playing when the insert button was pressed, the start of the presentation when the delete button was pressed "Erase point acquisition method" to obtain the time length from the point to the point (insertion point) that was playing when the erase button was pressed
Is defined.

Then, following the above method definition statement, ht
The description in the ml (Hyper Text Markup Language) language causes the browser 21 to start the player 22, and the window 2 configured by the browser 21 as shown in FIG.
Various objects are displayed in 1S. Also, ht
In the description in ml, the URL of the presentation played in the main area is "http://www.xyz.com/video/serieA.
rm "is included.

Specifically, in the window 21S, a player (playback player 22m) for reproducing the presentation in the main area is activated and displayed. Further, a player (called a player 22s) that reproduces clips in the sub area is activated and displayed.

Further, an input form is formed in which values are input and displayed when various buttons are pressed. Specifically, a start point input form f1 for inputting a start point, an end point input form f2 for inputting an end point, a reproduction time input form f3 for inputting a time length from the start point to the end point, Insertion point input form f where the insertion point is input
4. An erase point input form f5 for inputting an erase point is displayed.

Also, various buttons for the player 22m, that is, a play button bm1, a pause button bm2 and a stop button bm3, an insert button bm4 for obtaining an insertion point and inputting to the insertion point input form f4, and an erase point for an erase point. A delete button bm5 for inputting on the input form f5 is displayed.
Also, various buttons for the player 22s, that is, a play button bs1, a pause button bs2, a stop button bs3,
A start button bs4, an end button bs5, and a preview button bs6 are displayed. In addition, U of registered material
A pull-down menu m1 for selecting the RL and an edit end button b1 for ending the edit are displayed.

Concretely, an operation at the time of editing a clip requiring a material will be described. When the character string "Nakada" is displayed in the pull-down menu m1, the URL "http: //www.abc.c
"om / profile / player3.rm" is set in the player 22s. When the play button bs1 is pressed, this U
The material "player3.rm" specified by RL is played. It should be noted that the pause button bs2 can be used for temporary stop, or the stop button bs3 can be used for stop. For example, if the start button bs4 is pressed when the face of player Nakata 10 seconds after the beginning of the material "player3.rm" is displayed, the browser 21
Sends the event defined by the start point acquisition method to the player 22s, and the material "play
Since the time length "10 seconds" from the start point of "er3.rm" to the point playing at the time of event transmission is obtained, this value "10
Input the start point input form f1 with "second" as the start point.

On the other hand, when the play button bm1 is pressed, the URL "http: //www.xy" is displayed in the clip edit screen source.
The presentation containing the match of Serie A, which is designated by “z.com/video/serieA.rm”, is streamed from the streaming server 3. It should be noted that the pause button bm2 is used to pause or the stop button b
It can be stopped at m3.

Now, when the insert button bm4 is pressed at a desired timing, for example, the moment Nakata decides to shoot after 3 seconds from the starting point of the presentation "serieA.rm", the browser 21 makes the player 22m. On the other hand, the event defined by the insertion point acquisition method is sent out, and the player 22m can obtain the time length "3 seconds" from the start point of the presentation "serieA.rm" to the point being played when the event was sent out. This value "3 seconds" is entered as an insertion point in the insertion point input form f4. Also, when Nakata's appearance disappears from the screen 6 seconds after the beginning point,
When the delete button bm5 is pressed, the browser 21 sends the event defined by the delete point acquisition method, and from the player 22m, from the beginning point of the presentation "serieA.rm" to the point that was played when the event was sent. Since the time length "6 seconds" is obtained, this value "6 seconds" is input to the erase point input form f5.

When the edit end button b1 is pressed, the browser 21 sends the data entered in each input form to the edit server 1 as attribute information.

In the editing server 1, the attribute information storage unit 12
Updates the clip information database DB2 based on the data transmitted from the client 2. That is, in the clip information database DB2 shown in FIG. 4, the URL "http://www.abc.com/profi" sent to the record including the clip ID stored in advance for association
Material ID corresponding to "le / player3.rm", starting point "10
“Second”, insertion point “3 seconds” and erasing point “6 seconds” are stored.
Further, the end point "13 seconds" is obtained from these and set in the record.

Next, the editing of the text clip displayed in the sub area 5s will be described. FIG. 15 is a diagram showing an operation performed in the process of editing a clip editing screen and a text clip composed of a clip editing screen source with a main area. Regarding the editing of the text clip, the editing screen source for editing the text clip generated by the editing program generation unit 11 is also sent. Here, differences from FIG. 14 will be mainly described.

In this edit screen source, "reproduction method", "stop method", "insertion point acquisition method", and "erase point acquisition method" are similarly defined by the script language.

Also, the player 22s and the play button bs
1, pause button bs2, stop button bs3, start button bs4, end button bs5 and preview button b
s6 is not displayed, instead, a text input form f6 in which the content of the text clip is input, a pull-down menu m2 for selecting a background color, a pull-down menu m3 for selecting a character color, a vertical direction and a horizontal direction. Check button group b for selecting registration information of
t1, a pull-down menu m4 for selecting a font size, and a display time input form f7 for inputting the display time are displayed.

The operation when editing a text clip will be specifically described. For example, the content “Nakata is the central player of the Japanese national team ...” is input to the text input form f6. Also, pull-down menu m
2 and m3 are operated to select the background color and the character color. Further, the pull-down menu m4 is operated to select the character size. Further, the check button group bt1 is operated to determine the alignment information in the vertical direction and the horizontal direction.

Then, for example, the presentation "se
If the insert button bm4 or the delete button bm5 is pressed during the streaming playback of "rieA.rm", the browser 21 sends an event to the player 22m, and the obtained insertion point and deletion point are respectively input to the insertion point. Form f4
And the erasing point input form f5.

When the edit end button b1 is pressed, the browser 21 sends the data entered in each input form to the edit server 1.

In the editing server 1, the attribute information storage section 12
The clip information database DB2 is updated based on the data transmitted from the client 2. That is, the insertion point and the erasing point are stored in the record of the clip information database DB2 shown in FIG. Information about characters such as background color, character color, and font size is also stored. Also,
The time difference between the insertion point and the erasing point is stored as the display time.

When the editing of the synchronized multimedia presentation is completed through the clip editing process, the synchronized multimedia language file generation unit 13
Generates a synchronous multimedia language file by combining the attribute information stored in each of the databases DB1, DB2 and DB3 and stores it in the synchronous multimedia language file storage unit 14.

When the editing server 1 receives a request for a synchronous multimedia language file from an arbitrary client 2, the input / output unit 15 reads the requested file from the synchronous multimedia language file storage unit 14 and responds. To do. As a result, the client 2 plays the synchronized multimedia presentation edited by the above method.

The program for executing the above-described processing is recorded on a computer-readable recording medium such as a semiconductor memory, a magnetic disk, an optical disk, a magneto-optical disk, a magnetic tape, or a communication network such as the Internet. It can be transmitted through and widely distributed.
