  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of the invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory diagram showing a configuration of a video information management system according to the present invention. Reference numeral 1 denotes a server (first server 1a and second server 2) installed on a WAN 2 such as the Internet for storing and managing video data. Server 1b), 3 is a video data transmitting device for uploading video data to server 1 via WAN2, 4 is a camera connected to the video data transmitting device, 5 is a video for downloading video data from server 2 via WAN2. A data receiving device.

<First Embodiment>
FIG. 2 is a block diagram of the video data transmitting apparatus 3, and FIG. 3 is a block diagram of the video data receiving apparatus 5, showing the first embodiment of the present invention. As shown in FIG. 2, the video data transmitting device 3 includes a video input unit 10 that inputs an analog video signal or a digital video signal from the camera 4, a video compression unit 11 that performs video compression, and data after video compression. Are temporarily stored, a video data output unit 13 that outputs video data to the WAN 2, and a server setting unit 14 that stores a plurality of output destination servers set by the user. The video data output unit 13 includes a protocol change unit 13a that performs protocol change control according to the upload destination, and a key grant unit 13b that assigns an encryption key to the video data to be uploaded. Here, the server 1 set in the server setting unit 14 is the first server 1a and the second server 1b, and is set to preferentially use the first server.

  As shown in FIG. 3, the video data receiving device 5 includes a video data receiving unit 18 for downloading video data from the server 1, a server selecting unit 19 for a user to select a connection destination server, and a compressed video. A video development unit 20 that performs development and a video display unit 21 that displays video are provided. The video data receiving unit 18 includes a key release unit 18a that releases the encryption key assigned to the downloaded video signal.

The operation of the video information management system configured as described above is as follows. The video input unit 10 of the video data transmission device 3 receives an NTSC signal or a YCbCr digital signal from the camera 4 and performs format conversion to a video signal suitable for the input interface of the video compression unit 11. The video compression unit 11 is a compression method preset in the video compression unit 11 such as H.264. A compression codec such as H.264 or MPEG4 is selected to compress the input video signal and output to the video data storage unit 12.
The video data output to the video data storage unit 12 is an output destination set by the server setting unit 14 after being encrypted using the encryption key by the key granting unit 13b built in the video data output unit 13. For example, upload to the first server 1a via WAN2.

  As the encryption key, for example, a zip file with a password can be used, and the video protocol may be in a unique format. The video data output unit 13 formats and outputs video data in accordance with a protocol such as a general service API corresponding to the output destination server set by the server setting unit 14.

  The video data output unit 13 has a transmission confirmation function, and the video data uploaded and stored in the first server 1a is downloaded and confirmed. This confirmation operation is performed immediately after the uploading is completed, and the downloaded video data is compared with the video data (uploaded data) stored in the video data storage unit 12 to confirm whether or not the upload has been completed. This is because if you use an inexpensive general-purpose video distribution service at the upload destination, uploading may fail if traffic concentrates, so it is preferable to check whether uploading has failed. By downloading and reading the video data uploaded by the output unit, it is possible to confirm whether or not the transmission has been correctly performed.

  Note that this transmission confirmation does not need to confirm the entire moving image, but only the first frame constituting the moving image may be confirmed. For example, when video is transmitted at 30 frames / second, 1/30 second worth of video is transmitted. You can just check the video data.

  If it is determined that the uploaded video data could not be stored correctly in the first server 1a as a result of this confirmation, it is determined that the output destination server 1a cannot be used, and the upload destination is set to the server setting unit 14. It moves to the 2nd server 1b which is the other server 1 registered by (1). At this time, if the video data to be transmitted does not comply with the upload destination protocol, the protocol changing unit 13a downloads the protocol from the second server 1b that is the upload destination, reformats it, and performs the upload.

  FIG. 4 shows this series of flows. First, the server 1 as the upload destination of the video data is searched (S1), and if confirmed, the video data is transmitted and stored (S2). When the save operation is completed, the saved data is read (S3), compared with the video data before the save operation (S4), and if the data matches, the upload operation is terminated (S5). If they do not match, it is determined that the reading has failed, a new server 1 set in the server setting unit 14 is searched (S6), and the video data saving operation (S2) is repeated.

  In the above embodiment, the protocol is recognized when the video data is uploaded. However, the inexpensive general-purpose video distribution service is repeatedly established and abolished as needed. Because the protocol may change, it is desirable to periodically check the registered upload destination and the protocol such as the general-purpose service API corresponding to the server. If there is a protocol change, download it at that time. May be.

  The video data stored in the server 1 in this way is downloaded by the video data receiving device 5 as follows. The video data receiving unit 18 accesses the server 1 to which the video data transmitting device 2 has uploaded the video data according to the setting by the server selecting unit 19 and confirms the presence or absence of the video data. Here, the first server 1a is accessed to confirm that video data exists. When it is confirmed that there is video data, the video data is downloaded. Since the downloaded video data is encrypted with the encryption key, the key release unit 18a uses the decryption key to decrypt the downloaded video data file (releases the encryption key), and the video development unit 20 The decoded video data is decoded. In this way, the downloaded video is displayed on the video display unit 21.

In this way, the video captured by the camera is compressed and temporarily stored and uploaded to a server on the WAN such as the Internet at an arbitrary timing that is not real time, so the video data is not limited by the compression time or transmission time. And a free video distribution service provided by a general-purpose server on the Internet can be used. As a result, an image captured by a specific camera can be confirmed on a portable terminal or the like without installing a dedicated server, and a significant cost reduction can be realized as compared with a configuration using a dedicated server.
Since the encryption key is assigned, it is difficult for a third party to easily view the uploaded video even if the free video distribution service is used, and privacy can be protected.

In addition, when an error occurs in uploading, the upload destination server is changed, so that the situation where the captured video of the camera cannot be seen can be prevented. At this time, even when the video data to be output by the video data output unit is not configured with a protocol corresponding to the upload destination server, the protocol can be easily changed and the video data can be transmitted.
Furthermore, since the transmission state is confirmed by downloading, it is possible to reliably recognize the occurrence of an error, and the video data is definitely uploaded to any server.

Second Embodiment
FIG. 5 is a block diagram showing another example of the video data transmitting apparatus 3, and FIG. 6 is a block diagram showing another example of the video data receiving apparatus 5, showing the second embodiment of the present invention.
The video data transmission device 3 includes a video input unit 10, a video compression unit 11, a video data storage unit 12, a video data output unit 25, and a server setting unit 14, and the video data output unit 25 has a name. A name setting unit 25a for automatically setting a random number and a random number generation unit 25b for generating a random number are incorporated. In addition, about the thing which performs the operation | movement similar to the said FIG. 2, the same code | symbol is attached | subjected and description is abbreviate | omitted. The configuration of the entire system is the same as that shown in FIG.

The name setting unit 25a uses a unique number such as a device manufacturing number to set a file name or title that does not overlap with other devices, so that it is difficult for other general users who use the WAN to search. To make the name redundant. When the file name or title is set, the video data output unit 25 outputs the file name or title to the server 1 via the WAN 2.
This name setting is done because there is a problem that anyone can view the file name and title if the upload destination server is a general-purpose server that implements the video distribution service. By complicating the file name and title of the video data to be uploaded, it becomes difficult to specify by search.

  The video data receiving device 5 includes a video data receiving unit 26, a server selecting unit 19 for setting a server 1 to be accessed by a user, a video developing unit 20 for developing compressed video, and a video display for displaying video. The video data receiving unit 26 includes a search unit 26a that searches for the presence of video data. In addition, about the thing which performs operation | movement similar to the said FIG. 3, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  The operation of the video information management system configured as described above is as follows. The video imaged by the camera 4 is transmitted to the video data storage unit 12 via the video input unit 10 and the video compression unit 11. The video data output unit 25 attaches a name to the video data output to the video data storage unit 12 and outputs it to the WAN 2. At this time, the video data output unit 25 uses the built-in name setting unit 25a to attach a keyword to a name such as a file or a title and to provide redundancy using a random number. For example, the keyword “SA M PLE” is added to the file name, and a single digit value generated by the random number generator is inserted into two blank parts, respectively. For example, the name is created as “SA7M2PLE” and uploaded. . The uploaded video data is stored in, for example, the first server 1a, which is an output destination set by the server setting unit 14.

  The video data output unit 25 formats and outputs video data according to a protocol such as a general service API corresponding to the output destination server set by the server setting unit 14.

  The video data output unit 25 has a transmission confirmation function as in the above embodiment, and the video data uploaded and stored in the first server 1a is downloaded and confirmed. If it is determined that the uploaded video data could not be stored correctly in the first server 1a as a result of this confirmation, it is determined that the output destination server 1a cannot be used, and the upload destination is registered in the server setting unit 14 It moves to the 2nd server 1b which is the other server 1 which carried out. If the video data to be transmitted does not comply with the upload destination protocol, a protocol change unit (not shown) downloads the protocol from the second server 1b as the upload destination, reformats it, and performs the upload.

The video data stored in the server 1 is downloaded by the video data receiving device 5 as follows. The video data receiving unit 26 accesses the predetermined server 1 (here, the first server 1a) to which the video data transmitting device 3 has uploaded the video data according to the setting contents of the server selecting unit 19, and the search unit 26a is the name setting unit The existence of the file is confirmed by guessing the name such as the file name named in 25a and performing a search by a search method such as partial search. For example, a search is performed by sequentially entering arbitrary numerical values into two blanks of “SA M PLE”.
As a result of the search, when it is confirmed that the video data having the file name having “SA7M2PLE” exists in the server 1, the video data receiving unit 26 downloads the video data. The downloaded video data is decoded by the video development unit 20 and the video is displayed on the display unit 21.

In this way, the video captured by the camera is compressed and temporarily stored and uploaded to a server on the WAN such as the Internet at an arbitrary timing that is not real time, so the video data is not limited by the compression time or transmission time. And a free video distribution service provided by a general-purpose server on the Internet can be used. As a result, an image captured by a specific camera can be confirmed on a portable terminal or the like without installing a dedicated server, and a significant cost reduction can be realized compared to a configuration using a dedicated server.
Then, by adding a keyword including a random number to the video data and setting the name, it is difficult to search for a keyword even if a free video distribution service is used, and it is difficult for a third party to see, and privacy can be protected.

In the second embodiment, a file name or the like is created by adding a random number to a specific keyword, and the search unit searches the file name or the like by guessing. However, the server setting unit 14 asks the search unit 26a to A method that facilitates the search by notifying the file name or the like is also suitable.
In both the first and second embodiments, the video data transmitting apparatus 3 has the camera 4 as a separate body, but may be integrated.

  The video information management system of the present invention is applied to an interphone system so that the camera 4 images a visitor, the video data transmission device 3 is connected to or incorporated in the interphone master unit, and the video data reception device 5 is a mobile phone or the like. This portable terminal is suitable because it can check a visitor on the go, and can be applied to video data management when a camera equipped with a human sensor images a suspicious person. Furthermore, it can be used as an inexpensive transmission system when transmitting video data to a specific partner, not limited to images captured by a camera.
