Abstract

PROBLEM TO BE SOLVED: To display more information in one picture, to provide excellent operability and to furthermore improve the security of a video system. SOLUTION: A system control part 6 holds a hierarchically structured data base including not less than one video file and other additional information. The data base is displayed on a display part 1 based on the display instruction of the name of he video file of a control input part 4. The file selected by video file operation of the control input part 4 is transmitted by a transmission part 5 and displayed on the display part 1. In addition, before video file operation, a password is required to a user to limit the user capable of accessing an important directory. At the time of storing the video file, password information is added to additional information with the file name to stored in the system control part 6. Unless the password in additional information and that inputted by a user is coincident with each other, the user can not access to the video file.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video conference apparatus, and more particularly to a video conference apparatus suitable for improving the operability of a multimedia video conference system.

[0002]

2. Description of the Related Art In the conventional method used in this type of video conference apparatus, a still image or moving image file (hereinafter,
When displaying the file name of "video file", for example, the display form of the file name as shown in FIG.
Further, in the case of registering, the registration is randomly performed in a vacant place of the memory for storing.

[0003]

However, in such a method of the video conference apparatus, when a large number of video files are held, the video files can be searched and displayed as necessary information when necessary. Not only is it difficult to display a lot of information on one screen.

Further, since there is no mechanism for maintaining confidentiality regarding the held video file, there is a problem that anyone can access the confidential document.

The present invention solves the above-mentioned problems of the prior art, displays more information on one screen, has excellent operability, and further enhances the confidentiality of video files. The purpose is to provide.

[0006]

To achieve this object, the present invention provides a voice input means having a display means for displaying a still image, a moving image and other information, and a microphone for picking up a voice. And video input means equipped with a camera for photographing materials and attendees, operation input means for inputting various operations, and transmission means for communicating information such as images, voices and data with at least one other station. And a database which stores a file name and additional information attached to a video file encoded by one or more video encoding / decoding means, and which can be registered or displayed in a hierarchical structure so as to operate the operation input means. And a system control means for controlling the entire apparatus based on the signal.

[0007]

According to the above construction, when the file name of the database is displayed, all or part of the file name expressed in the hierarchical structure is displayed on the display means, and the selected video file is transmitted by the transmission means. Alternatively, it is displayed by the display means.

Further, when displaying the file name of the database, the system control means limits the video files that can be selected according to a preset user level.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a video conference apparatus according to the first embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a display unit such as a multi-scan type large display for displaying still images, moving images, and other information,
Reference numeral 2 is a voice input unit equipped with a microphone or the like for collecting the voices of the conference attendees, 3 is a video input unit equipped with a camera for photographing the conference attendees and scenes, and 4 is a mouse and a remote controller for performing various operation inputs. , A control input section equipped with a keyboard and the like, 5 a transmission section for exchanging information with other stations by communication, and 6 a H. In addition to 261 (ITU-TS recommendation), MPEG (Mo
ving PictureCoding Experts Group), JPEG (Joint
Photographic Coding Experts Group) and a system for controlling the transmission unit 5, the video input unit 3 and the like based on an operation signal given based on the operation of the control input unit 4 having at least one type of video encoding / decoding means. It is a control unit.

Further, FIG. 2 is a diagram showing a database of a video file expressed in a hierarchical structure of the present invention, and FIG. 3 shows detailed information of one video file in the database expressed in a hierarchical structure of the present invention. It is a figure.

The system control unit 6 holds a database of hierarchically structured video files including file names of at least one video file and other additional information as shown in FIG. The database of the hierarchically structured video files is held in the system control unit 6 by a memory storage method such as that found in the storage format of the UNIX system directory structure.

Further, when the file name is registered in the hierarchical structure as shown in FIG. 2, when the file name "important file C" is generated by adding "important" to the head name of the file name, The system control device 6 can store the video file in a directory or folder that is important according to the file name. This video file registered in the database can be partially or entirely displayed on the display unit 1 based on the file name display instruction of the control input unit 4. Further, it is possible to select a video file based on the video file operation of the control input unit 4, display detailed information of the video file as shown in FIG. 3, or transmit the video file to at least one other station. And

Next, the operation of the second embodiment of the present invention will be described. The second embodiment has a function of requesting a password from the user before shifting to the operation screen for operating the video file as shown in FIG. 2 in the video conference apparatus shown in the first embodiment. This is provided in the system control unit 6. The system control unit 6 manages each user level according to the password. Depending on the user level, it is possible to limit the users who can access the important directory of the still image directory shown in FIG. 2, for example.

When this password is recorded as a still image or a moving image and the image is saved as a video file, an encrypted password that cannot be referred to by the user is added as information to the additional information together with the file name. It is stored in the control unit 6. As a result, if the password of the additional information and the password entered by the user do not match when accessing the video file on the video file reference screen as shown in FIG. Allows you to set restrictions on who can access the file.

[0015]

As described above, according to the present invention,
By registering and displaying many video files of the video conference device in a hierarchical structure, the relationship between the video files can be easily understood and management can be performed easily, and more file names can be displayed. The user operability can be improved.

Further, when a video file is saved, a password is added to the additional information together with the file name, and the password can be used to limit the users who can access the video file, thereby improving the confidentiality of the video file. Has the effect.
