The present invention relates to a video service method for a mobile communication terminal, and more particularly, to capture a surveillance device such as a closed circuit television (CCTV) and a pan / tilt camera installed in a road, school, kindergarten, parking lot, etc. The present invention relates to a method of immediately displaying a video through a telephone call method using a mobile communication terminal in a SIP (Session Initiation Protocol) network.

The mobile communication terminal mentioned below is a video mobile communication terminal capable of displaying a video.

Around us, there are surveillance devices such as CCTV or pan / tilt cameras that monitor the surroundings or specific objects. CCTVs are installed on the road to monitor the traffic of vehicles, and CCTVs or pan / tilt cameras are installed in places requiring protection or surveillance, such as banks, apartment playgrounds, parking lots, kindergartens, and schools. The images captured by these monitoring devices are provided to the control system of the management room or the central control room and used by the manager of the control system as monitoring information.

Until now, the video captured by the monitoring device was private information that can only be checked at specific places, such as the management office or the central control room.However, the information captured by the monitoring device is now combined with the development of the Internet and communication technology, public interest, and operators. Can be found on the Internet.

For example, the Road Traffic Safety Authority or other Internet homepages related to traffic provide a service for checking CCTV installed on roads in each region for the driver's safety and smooth traffic communication. In addition, the Internet homepage opened by some institutes (kindergarten, academy, playroom, etc.) provides a service that allows users to check CCTV or pan / tilt cameras installed in the institute to check their children's life.

In addition, the three telecommunication companies are providing a service that can check the video of the road traffic situation recorded through CCTV for the mobile communication terminal capable of video display.

Although the use of surveillance video from the surveillance device is still very limited, the range of application will be expanded as the technology is developed and user desire is increased. In order to expand the range of application of the monitoring device, it is necessary to easily retrieve and display the captured image of the monitoring device and to check the shooting information of the monitoring device anywhere.

By the way, as described above, a technique for confirming photographing information of a monitoring apparatus is provided anywhere using a mobile communication terminal, but a technique of immediately providing photographing information of a desired place or a monitoring apparatus is not provided.

That is, the method of checking the captured image of the monitoring apparatus using the currently disclosed mobile communication terminal selects a menu to access the Internet from the menu of the mobile communication terminal, accesses the Internet, and then enters a URL or is provided by the mobile communication terminal. The road traffic information menu is selected from the menu tree, and a location list list of the monitoring apparatus provided as a submenu of the road traffic information menu is performed.

This process requires time to set up a call path between the mobile terminal and the server, and because the screen is smaller than the computer and the data processing method is different, the information is provided as text list information. After this process, it is necessary to have a time to call the desired information, so there is a problem in that the shooting information of the monitoring device cannot be immediately provided to the user.

Accordingly, an object of the present invention is to solve a conventional problem, and an object of the present invention is to enable a user of a mobile communication terminal to immediately check a captured image of a monitoring device desired by a user through a mobile communication terminal with a single service request. do.

The present invention for achieving the above technical problem is to manage a plurality of connected monitoring devices by different Session Initiation Protocol (SIP) Uniform Resource Identifiers (URI), the image providing server for providing the captured image to the mobile communication terminal And a method of immediately displaying a video captured by a specific monitoring device using the mobile communication terminal in a SIP network including a SIP switch, wherein the mobile communication terminal makes a call using a first SIP URI as an invitation message according to a user's request. A first step of attempting a second step, the SIP exchanger receiving the first SIP URI, and forwarding a SIP call to the video providing server in charge of the received first SIP URI; The third step of identifying the monitoring apparatus corresponding to the first SIP URI and the photographed image photographed by the checked monitoring apparatus. And a fourth step of providing at the end, and a fifth step of displaying the photographed image corresponding to the SIP URI of claim 1 wherein the mobile communication terminal received in the display.

Hereinafter, a method of immediately displaying a moving picture photographed by a specific monitoring apparatus according to an exemplary embodiment of the present invention using a mobile communication terminal will be described with reference to the accompanying drawings.

First, an image providing system according to an example for achieving the present invention will be described with reference to FIG. 1. 1 is a block diagram of an image providing system for achieving the present invention, which is a system applied when a photographed image of a monitoring device managed by a plurality of operators (or institutions) is serviced to a mobile communication terminal according to the present invention. It is a block diagram.

As shown in FIG. 1, the image providing system for the present invention has a plurality of image providing servers 31, 32, and 33. The plurality of video providing servers 31, 32, and 33 have different IPs, and each of the video providing servers 31, 32, and 33 has a plurality of monitoring devices 31a, 31b or 32a, 32b, or 33a managed by the video providing servers 31, 32, and 33a. , 33b) are connected.

The monitoring devices 31a to 33b are CCTV or pan / tilt cameras, and are provided with different SIP Uniform Resource Identifiers (URIs). Here, the fact that the SIP URI is assigned to each of the monitoring devices 31a to 33b does not mean that the SIP URI is stored in each of the monitoring devices 31a to 33b. It means to use URI as identifier of each monitoring device.

The use of the SIP URI as an identifier of each monitoring apparatus by the image providing servers 31, 32, and 33 is to enable the user to determine which monitoring apparatus is input the currently captured video, and in particular, the mobile communication terminal 10. In order to allow the user of the IPTV to request the captured image of the monitoring apparatus from the video providing server 31, 32, or 33 by using the SIP URI as a call command.

According to this intention, the image providing servers 31, 32, and 33 utilize SIP URIs in a camera mapping table as shown in FIG. 4. 4 is a simplified diagram of a camera mapping table stored in an image providing server according to an embodiment of the present invention, in which a table previously managed with input port numbers as mapped identifier information of each monitoring apparatus is applied. .

As shown in FIG. 4, the camera mapping table stored in each video providing server 31, 32, and 33 includes column index fields such as a port number field, a SIP URI field, and a device information field. Corresponding information is recorded. If the mapping table stored in the existing Internet server is a table for identifying a monitoring device by an identifier other than an input port number and managing a captured image of each monitoring device, the present invention provides a 1: 1 SIP URI to the identifier. By mapping it creates a camera mapping table that can be utilized by the present invention. The image providing servers 31, 32, and 33 may classify the captured images of the connected monitoring apparatuses by the camera mapping table.

The SIP URI has a form of an invitation message generally used, for example, "sip: gaepo-jungong.apt1@gangnam.go.kr " .

The mobile communication terminal 10 is a terminal having a display device capable of requesting and receiving a SIP service through a mobile communication network and outputting a moving image or a still image. The SIP exchanger 20 stores a service profile for the mobile communication terminal in charge thereof, and responds to the invitation message of the mobile communication terminal in charge of the mobile terminal in response to the video providing server 31, 32, 33. ).

When the transcoding unit receives real-time image information from the image providing servers 31, 32, and 33, the transcoding unit converts the audio / video stream information into a form that can be displayed by the mobile communication terminal 10, and then the mobile communication terminal. To 10.

The SIP exchanger 20 stores the information of the video providing servers 31, 32, and 33 that are in charge of each SIP URI, and the video providing servers 31, 32, and 33 that are in charge of the received SIP URI. It generates a SIP call for establishing a video call channel between the 10 and the incoming call to the corresponding video providing server 31, 32, 33.

In the above, it is preferable that the communication between the mobile communication terminal 10 and the image providing servers 31, 32, and 33 be unidirectional (that is, the direction from the image providing servers 31, 32, 33 to the mobile communication terminal 10). Do.

Hereinafter, the concept of the present invention will be described with reference to FIG. 2 is a conceptual diagram of a method for immediately displaying a moving image photographed by a specific monitoring apparatus of the present invention by using a mobile communication terminal.

As shown in FIG. 2, when the user inputs the SIP URI # 2 of the monitoring apparatus to check the captured image into the mobile communication terminal 10, the mobile communication terminal 10 uses the SIP URI # 2 as an invitation message. Send to the SIP switch 20. Then, the SIP switch 20 receives the SIP URI # 2, determines the video providing server 30 managing the SIP URI # 2, and then sends the SIP call to the video providing server 30.

Accordingly, the image providing server 30 processes the received SIP call so that unidirectional communication is performed between the mobile communication terminals 10, and then applies SIP URI # 2 to the camera mapping table to capture shooting information of the matching monitoring device. And the captured photographing information is transmitted to the transcoding device 40. The transcoding device 40 converts the photographing information of the received monitoring device according to the real-time audio / video stream standard and then transmits the captured information to the mobile communication terminal 10.

Then, the mobile communication terminal 10 displays the captured image of the corresponding monitoring device received in real time through the screen.

The concept of the present invention described with reference to FIG. 2 will be described in more detail with reference to the embodiment of the present invention with reference to FIG. 3. 3 is a flowchart illustrating a method of immediately displaying a video captured by a specific monitoring apparatus according to an exemplary embodiment of the present invention using a mobile communication terminal.

As shown in Figure 3, the user inputs the SIP URI of the monitoring device to check the image to the mobile communication terminal 10 and then press the transmit button (S300).

Here, those skilled in the art can add a predetermined function to the mobile communication terminal 10 so that a user does not directly input a SIP URI of the monitoring apparatus. For example, it may be provided with a dedicated button for managing the SIP URI input by the user, such as an address book, or a dedicated button for executing the method of the present invention. On the other hand, when the user directly enters the SIP URI, the service provider to provide the SIP URI of the monitoring device through the home page of the Internet, to provide a phone book for the SIP URI of the monitoring device or to provide a URI search service Is good. In this case, when providing the SIP URI to the user as private information, it is preferable to provide a procedure for filtering the user, i.e., checking whether the subscriber is a person who may provide the corresponding SIP URI.

When the SIP URI is determined by user input or selection, the mobile communication terminal 10 transmits the SIP URI # 2 as an invitation message to the SIP switch 20 (S302). Then, the SIP exchanger 20 analyzes the invitation message, grasps the video providing server 31 in charge of SIP URI # 2, and sends a SIP call to the identified video providing server 31 (S303 and S304).

When the SIP call is received from the SIP exchanger 20, the image providing server 31 determines the subscriber information included in the SIP call to determine whether the subscriber may provide photographing information of the monitoring apparatus (S305). Here, the image providing server 31 or a separate server (i.e., a server storing subscriber information) located in a SIP network (not shown) may call a SIP URI, that is, information about a subscriber who may receive a service. It is stored.

Here, the subscriber information stored in the image providing server 31 or a separate server is classified into three types according to the method of photographing image service of the monitoring apparatus. The first is the case where the surveillance video of all surveillance apparatuses is public information, and the second is the case where the surveillance video of the surveillance apparatus is managed publicly and privately. The third is the private information. This is the case.

In the first case, the subscriber information is all managed in the same form so as to provide shooting information of all monitoring devices to the service registrant. In the second case, subscriber information manages registered subscribers to receive shooting information of surveillance devices classified as non-public information from general subscribers.In this case, subscribers who receive shooting information of private information are subscribers of public information. Separately identify, store and manage additional personally identifiable information. In the third case, the subscriber information is managed according to each SIP URI. Accordingly, in the third case, even if the service subscriber requests a SIP URI other than the SIP URI specified at the time of subscription, the service is rejected.

When the video providing server 31 determines that the subscriber can call SIP URI # 2 through the subscriber identification process (S305), the video providing server 31 sets up a video call channel for performing one-way communication with the mobile communication terminal 10 to process the SIP call. Do By doing this SIP call processing, the service provider server 31 and the mobile communication terminal 31 is a session start is made.

When the session is initiated, the video providing server 31 and the mobile communication terminal 10 negotiate communication with each other, and the mobile communication terminal 10 transmits its codec information to the video providing server 31. In addition, the image providing server 31 compares the codec information provided from the mobile communication terminal 10 with its own codec information to determine whether the codec is identical or inconsistent.

After the communication negotiation is made, the image providing server 31 applies the SIP URI # 2 requested by the mobile communication terminal 10 to the stored camera mapping table to identify the monitoring device 32b and the input port corresponding to the SIP URI # 2. Then, the captured video captured by the captured monitoring device 32b is obtained (S306).

Image providing server 31 provides the shooting information of the SIP URI # 2 obtained through the process (S306) to the mobile communication terminal 10, the mobile communication terminal 10 can process the shooting information transmitted by itself. The transmission path (that is, data processing) varies depending on whether the terminal is present. If the image providing server 31 determines that the result determined through the negotiation process is a model capable of processing the captured image (S307), the monitoring apparatus 32b corresponding to the SIP URI # 2 is set through the set video call channel. The video is transmitted to the mobile communication terminal 10 as a media stream (S309).

On the other hand, if the image providing server 31 determines that the model of the mobile communication terminal 10 does not support the captured image (S307), and transmits the captured image to the transcoding device 41, the captured image. Then, the transcoding device 41 converts the received photographed image into a video form that can be processed by the codec of the mobile communication terminal 10 and transmits it to the mobile communication terminal 10 (S309).

As a result, the mobile communication terminal 10 immediately displays the captured image corresponding to the SIP URI # 2 desired by the user through the above-described process.

 The technical spirit of the present invention has been described above with reference to the accompanying drawings, but this is by way of example only and not intended to limit the present invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.

The present invention can utilize a system for providing a video recording of the existing monitoring device, the user inputs or selects the SIP URI of the monitoring device that the user wants to see in the mobile communication terminal to shoot the monitoring device corresponding to the SIP URI The information can be immediately checked through the mobile communication terminal.
