[0040]
1. Timeline display processing
The timeline display processing will be described with reference to the flowcharts of FIGS. 6, 7, and 8. First, the moving image editing apparatus 1 receives a registration request for layout information and a registration request for clip information transmitted from the terminal 2, and stores the received layout information in the layout information database DB1 based on the registration request. Is registered in the clip information database DB2. Thus, information as shown in FIGS. 3 and 4 is stored.
When the layout information and the clip information are stored, the attribute information display unit 16 detects the number of areas to be displayed from the registered layout information database DB1 based on the area ID, and, based on the detection result, determines the timeline. Is determined (step S1). Next, the attribute information display unit 16 reads the area ID from the layout information database DB1 (step S2), reads the reproduction time information and the attribute information corresponding to the read area ID from the clip information database DB2 (step S3), and reads them. Based on the playback time information and the attribute information, the generated timeline generates a timeline display source, and transmits the source to the terminal 2 via the network by the communication unit 15 (step S4). Here, the attribute information for displaying the moving image and the still image is extracted as the attribute information for displaying the text itself stored in the item of the content on the timeline in the case of the file name and the text. The item of the attribute information to be extracted can be changed in accordance with an instruction from the terminal 2.
[0041]
Upon receiving the timeline display source transmitted from the moving image editing apparatus 1, the terminal 2 generates a separate timeline for each region ID from the received timeline display source and displays the timeline on the screen (step S5). FIG. 9 shows an example of information displayed on this screen. In this figure, since there are two regions to be edited (sub screen and main screen), two time lines are displayed in the display field of the time line indicated by reference numeral (a). Here, in the timeline of the sub-screen indicated by the reference numeral (b), the text of "Italy Soccer" is displayed from 0 to 28 seconds, and the moving image of the file name "Serie A-1" is displayed from 28 to 110 seconds. Is displayed, and a timeline is displayed indicating that the text "Result ..." is displayed from 110 seconds to 135 seconds.
On the time line of the main screen shown by the symbol (c), a still image of the file name “Serie A-Logo” is displayed from 0 seconds to 40 seconds, and “the latter half 20 minutes ...” from 40 seconds to 98 seconds. Is displayed, and a timeline is displayed indicating that the text "Ube logo" is displayed from 98 seconds to 135 seconds.
[0042]
In the editing work column shown by reference numeral (d), a sub screen and a main screen are displayed, and any one of the areas is designated to perform editing work such as reproduction, stop, insertion point, and erasing point. A click button or the like having the function of is displayed. In this display, the editing program generation unit 11 generates HTML source code of a layout creation screen for obtaining layout information (abbreviated as a layout screen source, and a similar source code is abbreviated as a “screen source” at the end thereof). Then, the communication unit 15 transmits the layout creation screen source to the terminal 2.
[0043]
As described above, the playback time at which a moving image, a still image, or a text is played is displayed on the terminal 2 in association with the elapsed time, so that the user can easily grasp the edited contents of the edited streaming. Is possible.
[0044]
2. Information change processing
Next, information change processing will be described with reference to the flowchart of FIG. 10 and FIGS. When the user clicks an insertion point or an erasure point on the timeline, a file name, text, or the like using an input device such as a keyboard or a mouse of the terminal 2 and inputs an editing instruction (step S11), the terminal 2 proceeds to step S11. An editing instruction including the area ID of the timeline to which the editing instruction has been input is transmitted to the moving image editing apparatus 1 according to the editing content (step S12).
[0045]
The editing instruction receiving unit 15a of the moving image editing apparatus 1 receives the editing instruction transmitted from the terminal 2 (Step S13) and outputs to the information changing unit 17. The information changing unit 17 detects the area ID from the editing instruction, and stores and updates the attribute information corresponding to the detected area ID in the clip information database DB2 by overwriting the attribute information corresponding to the detected area ID according to the editing content of the editing instruction. (Step S14).
[0046]
When the attribute information is updated, the synchronous multimedia language file creator 13 creates a multimedia integrated language file (step S15) and stores it in the synchronous multimedia language file storage 14.
[0047]
Here, a timeline when an editing instruction is given for a text will be described with reference to FIG. To the text of the "Hello" of the timeline area I shown in FIG. 11 (a), the rewritten to "HELLO" by the input device of the terminal 2, the moving picture editing apparatus editing instruction corresponding to this rewriting is generated 1 and reflected in the clip information database DB2. Thus, when the text is rewritten, the changed text is displayed in the area as shown in FIG. 11C from FIG. 11D.
[0048]
Also, as shown in FIGS. 12 (a) and 12 (b), when an editing instruction for changing the reproduction time information is input, the text “Good morning” in the clip information database DB2 is deleted according to the editing instruction. the insertion point of the point and the text "Hello" is updated. As a result, in the region I, the text "Hello" to be displayed on the 45 th second is updated so as to be displayed on the 60 th second.
[0049]
As mentioned above. The user can perform an editing operation by inputting an editing instruction to the displayed timeline, whereby the user plays the streaming and waits until the timing for editing to perform the editing operation has arrived. You can save time and effort.
