The identification information of 215-N is stored in the storage unit 230. In addition, the IP allocation module 250a transmits the extracted dynamic private IP to the corresponding video encoder 215 -N to set the IP of the video encoder 215 -N.

3 is a flowchart illustrating a method of allocating an IP of an image encoder by a mobile communication controller according to an embodiment of the present invention.

In the description with reference to FIG. 3, it is assumed that the image encoder # 1 215-1 requests an IP allocation to the mobile communication controller 250.

Referring to FIG. 3, the video encoder # 1 215-1 that is powered on or attempts to access the mobile communication controller 250 for the first time transmits an IP allocation request message to the mobile communication controller 250 (S301). At this time, the video encoder # 1 215-1 records its identification information in the IP allocation request message.

Then, the mobile communication controller 250 activates the IP allocation module 250a, and the activated IP allocation module 250a extracts the unassigned dynamic private IP from the IP pool of the storage 230 (S303). Subsequently, the IP allocation module 250a checks the identification information of the image encoder # 1 215-1 recorded in the IP allocation request message, and identifies the identification information of the image encoder # 1 215-1 and the extracted dynamic private IP. Map to store in the storage 230. The IP allocation module 250a transmits the extracted dynamic private IP to the video encoder # 1 215-1 through short range wireless communication protocol (S305).

Next, the video encoder # 1 215-1 sets the dynamic private IP received from the mobile communication controller 250 as its own IP (S307). Subsequently, when an image signal is received from the camera # 1 213-1, the image encoder # 1 215-1 encodes the image signal into a predetermined standard and stores the image signal in the memory # 1 211-1. The IP (that is, the dynamic private IP) is set as the source IP and the encoded video data is transmitted to the mobile communication controller 250 (S309 and S311).

Then, the mobile communication controller 250 checks the source IP of the received image data, and checks the storage encoder 230 for image encoder identification information (ie, identification information of the image encoder # 1) corresponding to the source IP. . Subsequently, the mobile communication controller 250 adds identification information of the image encoder # 1 215-1 to the image data, sets a source IP as its own IP (that is, a public IP), and then manages the image data. Transmission to the center 100 (S313).

Next, the management center 100 decodes the received image data and checks the source IP of the image data (that is, the official IP of the mobile image transmitting apparatus). Subsequently, the management center 100 recognizes the mobile video transmitting apparatus 200 that has transmitted image data among the plurality of mobile video transmitting apparatuses 200 based on the source IP, and displays the mobile video transmitting apparatus 200. The decoded video data is output to the monitor designated by the means (S315).

Preferably, the management center 100 divides the screen of the monitor so as to correspond to the number of cameras 213 -N of the mobile image transmitting apparatus 200, and each image encoder 215 -N is divided into the divided screens. Outputs the image screen shot in. In other words, the management center 100 extracts the encoder identification information from the received image data, and the received image data is provided in the mobile image transmitting apparatus 200 based on the encoder identification information. The image encoder 215-N from among N) is recognized, and the decoded image data is output to the split screen of the recognized image encoder 215-N. For example, when four video encoder devices 215 -N are provided in the mobile video transmitting apparatus 200, the management center 100 may display a large monitor screen designated as a display means of the mobile video transmitting apparatus 200. The video data in which the identification information of the video encoder # 1 215-1 is recorded is output to the first divided screen, and the video data in which the identification information of the video encoder # 2 215-2 is recorded is output to the second screen. Output to split screen.

On the other hand, the mobile image transmission device 200 reports the changed official IP to the management center 100 when its IP is changed in accordance with the position movement in order to continuously transmit the image taken while moving to the management center 100. do.

4 is a flowchart illustrating a method of reporting changed IP information to a management center in a mobile video transmitting apparatus according to an embodiment of the present invention.

Referring to FIG. 4, when the mobile video transmission device 200 moves from the first region to the second region, the mobile communication controller 250 may be an IP allocation server built in the mobile communication network 500 (not shown in the drawing). A new public IP is assigned from (S401). In detail, the mobile communication network 500 manages a public IP pool for each region, and performs a process of assigning a public IP of a mobile communication terminal or a mobile video transmission device 200 based on the public IP pool for each region. That is, when the mobile video transmission device 200 enters a specific area requiring new public IP allocation while the mobile video transmission device 200 is recording while moving the surrounding video, the mobile communication control unit 250 of the mobile video transmission device 200 may use the mobile communication network. 500 is assigned a new public IP used in the area.

The mobile communication control unit 250, which is assigned the new public IP, notifies the DDNS 300 of the changed public IP (S403). At this time, the mobile communication control unit 250 also transmits the identification information of the mobile image transmission device 200 to the DDNS (300). Then, the DDNS 300 checks the domain name and the public IP corresponding to the identification information of the mobile video transmission device 200, and updates the verified public IP to the public IP notified (S405). Subsequently, the DDNS 300 transmits an IP change notification message in which the updated public IP and the domain name of the mobile video transmission device 200 are recorded to the management center 100 (S407).

Then, the management center 100 extracts the domain name from the IP change notification message, and updates the public IP mapped to the extracted domain name to the public IP recorded in the IP change notification message. The management center 100 checks the image data of the mobile image transmitting apparatus 200 and outputs the image data to a designated large monitor based on the official IP of the updated mobile image transmitting apparatus 200. To continuously monitor the surroundings of the mobile image transmission device 200 (S409).

Through this procedure, the mobile video transmission device 200 notifies the management center 100 through the DDNS 300 of the changed public IP, while the management center 100 is the public IP of the mobile video transmission device 200. Recognize the change. Accordingly, the management center 100 recognizes the image data received from the mobile image transmitting apparatus 200 and accurately outputs the designated large monitor even when the public IP of the mobile image transmitting apparatus 200 is changed.

Try. The monitoring application is an application for receiving image data by connecting the mobile image transmitting apparatus 200 and is mounted on the client terminal 400.

The client terminal 400 attempting to access the mobile video transmission device 200 first queries the DDNS 300 for a public IP corresponding to the domain name (S501). Then, the DDNS 300 checks the public IP of the mobile video transmission device 200 corresponding to the domain name, and transmits the public IP to the client terminal 400 (S503). Next, the client terminal 400 transmits a video data request message in which the received public IP is set as a destination address to the mobile video transmission device 200 (S505).

Then, the mobile communication control unit 250 of the mobile image transmission device 200 transmits a message requesting identification information of the image encoder 215 -N to the client terminal 400 before transmitting image data (S507). ). In other words, since the mobile terminal 250 is smaller than the monitor screen provided in the management center 100, the mobile communication controller 250 does not transmit all the image data collected from each encoder 215 -N. In order to transmit only the image data collected by the image encoder 215 -N to the client terminal 400, a message for requesting identification information of the image encoder 215 -N is transmitted to the client terminal 400. Preferably, the mobile video transmission device 200 transmits the video encoder identification information list to the client terminal 400 to request the selection of any one of the video encoder identification information list.

Then, the client terminal 400 selects any one of the identification information included in the video encoder identification information list, and transmits the selected video encoder identification information to the mobile video transmission device 200 (S509). Next, the mobile video transmission device 200 checks the dynamic private IP corresponding to the received video encoder identification information in the storage unit 230 and collects the video from the video encoder 215-N having the dynamic private IP. The image data is transmitted to the client terminal 400 (S511 and S513). That is, the mobile video transmitting device 200 does not transmit all video data collected from each video encoder 215 -N to the client terminal 400, but the video encoder 215 -N designated by the client terminal 400. Only the image data collected from the client terminal 400 is transmitted.

Through the method of FIG. 5, a specific user can check the surrounding image of the mobile image transmitting apparatus 200 at a remote location and take appropriate measures according to the received image screen. For example, when the manager instructing the installation of the mobile video transmitting apparatus 200 is located at a place other than the management center 100, the mobile terminal is connected to the mobile video transmitting apparatus 200 to access the image data. By receiving, you can check the status of the area in real time.
