Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic library management system for managing, for example, video information and audio information recording the situation of a construction work site.

[0002]

2. Description of the Related Art Conventionally, a construction work site (hereinafter referred to as a site)
At the time of recording the situation of the site, the situation of the site is photographed by a video photographing device, and the photographed video is developed, edited, organized and stored. When shooting on-site, the location and construction name are recorded in the video by shooting and recording the location of the construction and the blackboard on which the construction name is written along with the situation of the site. When the image capturing device is a camera for capturing an image on a film, the filmed film is handed to a trader, who develops and prints the film, and arranges and stores the printed photographs. When the image capturing device is a digital camera, the captured data is taken into a computer or the like, edited and managed by the computer, and the captured data is printed out by a printer as necessary. If the video camera is a video camera, request a videotaper that has already been shot to a specialized vendor to edit the shot contents, or take a videotape that has been shot (the video is recorded intermittently. ) Is managed.

In general, such image capturing, editing, operation, and storage management are generally performed by using different systems and methods depending on applications and hardware as exemplified below. . Examples of shooting purposes include site monitoring and public relations video. As the recording medium, a video tape medium (VHS, Hi-8, DV, Betacam, etc.), or a digital medium in which photographed data is transmitted and accumulated using a communication line such as a ground line is used. For editing, a dedicated device for editing a video tape medium or a dedicated device for editing digital media is used. As the operation management, after editing, the video tape medium is recorded and the video tape medium is operated and stored (ledger management, etc.).

[0004]

When the shooting contents recorded on the recording medium are edited in the field, it is sometimes desired to record the shooting status in addition to the date and time, place and construction name at the time of shooting. In that case, it is common to take notes. However, it is difficult to handle complicated on-site situations accurately and in a short time. Further, if the situation of the scene is recorded by using a lot of video, there is a disadvantage that the amount of post-processing and the amount of editing increase depending on the amount of video recorded. Moreover, when a third party is requested to perform such post-processing or editing work, the intention of the editing may not be completely transmitted to the third party, and the editing may be different from the desired one. . In order to avoid such an inconvenience, it is necessary to carry out careful meetings and adjustments. Further, it is difficult to bring in a computer for processing information such as shooting contents (video) recorded on site on the spot because the scale of the computer is large. Therefore, a portable information processing device having a processing capability equivalent to that of a computer capable of image processing, such as an electronic notebook or a mobile phone, is required, but it is not found at this time.

The following exist as existing technologies for transmitting information via a network. That is, a system that transmits and receives data between a server and client computers via a network, a system that grasps (monitors) the state of the network,
There are a system for delivering video on a network, a system for accessing a database from a web browser via a web server, a system for recognizing voice on a computer, and a system for managing time on a network (time server). Then, a photo management system or the like is known in which these technologies are individually used to statically manage image data. However, these existing technologies have the following drawbacks, and thus it is difficult to realize the input, editing, operation, and storage management of information recorded at a site with a simple configuration. 1) In a system for transmitting / receiving data between a server and a client computer via a network, there is no system for directly transmitting / receiving a camera image. There is a network camera that sends video over the network, but in this case it is standardized for the network camera,
It has no other functions. Moreover, the function of adjusting the physical interface and protocol is required. 2) It is possible to deliver the information to the computers on the network by using the system that grasps (monitors) the state of the network, but only within the network. Moreover, the function of adjusting the physical interface and protocol is required. 3) A network video distribution system (streaming server) is used as a system for distributing video on the network.
However, since it is unidirectionally flowing, individual frame data being distributed is not guaranteed. A method for uniquely managing ID and time information is required. 4) A system that manages time on the network (time server) creates standard time for the entire system and adjusts a clock unique to each computer. This function is provided to a higher-level computer or a network management server, etc., to ensure the time consistency of the entire network. This corrects the terminal device. However, a system for performing such time management cannot be controlled up to the specific time of a terminal device that exists outside the network and is not always connected. The present invention has been made in view of such circumstances,
It is therefore an object of the present invention to provide an electronic library management system and method capable of realizing input, editing, operation, and storage management of information recorded at a site or the like with a simple configuration.
