Abstract

PURPOSE:To improve the production efficiency of moving image reedition by providing this remote editing processor with an editing operation means for editing a moving image based upon index information. CONSTITUTION:The remote editing processor consists of a communication network 1, a moving image file server 2, a work station 3, and a moving image work station 6. A moving image is mainly stored in the server 2. The internal structure of a moving image file consists of attributes 11 such as image size and a color space, moving image data 13 and link information, an index is previously allocated to the file and the editing operation of the moving image is executed by the editing operation means based upon the index information. The moving image editing work is allocated to the work station 3 capable of editing a static image and the moving image editing work station 6. Thereby, the resource of the work station 6 can be effectively utilized.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving image remote editing processing device.

0002

2. Description of the Related Art Conventionally, as a tool for storing and editing moving images such as computer graphics and animation, there has been a moving image editing processing device having a moving image storage means.

As shown in FIG. 4, this has a moving image display section 41, a moving image editing section 42, a moving image storage section 43, and an operation instruction section 44, and an internal bus 45 is used for editing. The time axis was cut and pasted using

However, such a moving image editing processing device is expensive because it requires high-speed processing of a large amount of data, and usually only one person can use it at a time, resulting in high editing costs.

[0005] It is an object of the present invention to solve these conventional problems and to make it possible to reduce editing costs.

[0006]

[Means for Solving the Problems] In order to achieve this object, the moving image editing processing device of the present invention has a moving image storage means for storing moving images and a still image editing device for editing still images connected to a network. the moving image in the moving image storage means has index information of at least one still image data, and the still image editing device includes an editing operation means for editing the moving image based on the index information. It is characterized by having

[0007]

[Operation] As shown in FIG. 1, a system to which the moving image editing processing device according to the present invention is applied includes a communication network 1,
It consists of a moving image file server 2, a workstation 3, and a moving image editing workstation 6. The moving image file server 2 has a moving image storage section 21 and a communication section 22, and the workstation 3 has an editing instruction section 31, an operation input section 32,
The video editing workstation 6 includes an image display section 33, a communication section 34, a video editing section 61, an operation input section 62,
It has a moving image display section 63 and a communication section 64.

[0008] In this system, moving images are mainly stored in a moving image file server 2. The internal structure of a moving image file is as shown in Figure 2.
It consists of attributes 12 such as color space, video data 13, and link information 14, and an index 11 is assigned to these in advance.
It is characterized by the addition of. Assume a plurality of moving image files having such a configuration.

[0009] In the present invention, the editing operation means performs an editing operation on a moving image using this index information.

0010

[Examples] The present invention will be specifically explained below based on Examples.

FIG. 3 is a basic operational flow diagram according to the present invention. The main moving image editing operations of the present invention are as follows.

Step 100: Access the moving image file server 2 on the workstation 3 capable of editing still images, and extract a plurality of necessary moving image files from the moving image files using the index 11 (still images).

Step 110: The extracted indexes 11 (still images) are rearranged on the workstation 3.

Step 120: On the workstation 3, the extracted indexes 11 (still images) are joined together as one index image file.

Step 130: On the workstation 3, access the video file server 2 and create a partial still image every several frames of the video to be indexed (some of the frames of the video are skipped to create still images). combination of things).

Step 140: Confirm by flipping through partial still images on the workstation 3.

Step 150: Send the editing results on the workstation 3 to the moving image editing workstation 6.

Step 160: The moving image editing workstation 6 converts the stitched index (still image) into a stitched moving image file, and removes unnecessary parts of the stitched moving image file.
to add. Next, check the finished product with a video image.

A feature of the present invention is that the moving image editing work is divided between the workstation 3 capable of editing still images and the moving image editing workstation 6. As a result, the resources of the moving image editing workstation 6 can be effectively utilized.

Although the system shown in FIG. 1 includes one moving image file server 2, one workstation 3, and one moving image editing workstation 6, there is no limit to the number of these. , may be plural. Furthermore, the communication network 1 is not limited to Ethernet using a coaxial cable, but may also be, for example, FDDI (optical fiber 100MHz network).
, wireless, etc. can be used.

[0021] Furthermore, there is no restriction on the order of the internal structure of a moving image file. The order of the processing contents by the workstation 3 or the order of the processing contents by the moving image editing workstation 6 can be changed or looped as necessary.

[0022]

[Effects of the Invention] As described above, according to the present invention,
An index is added to the inside of the moving image file in advance, and the editing operation of the moving image is performed using the editing operation means using this index information.
By sharing the video editing processing and display work, the production efficiency of video editing is improved.
