2, a CCTV video service providing server 300 according to an exemplary embodiment of the present invention includes a first receiving unit 310, a storage unit 320, a second receiving unit 330, a holding unit 340 A conversion unit 350, a transmission unit 360, a control unit 370, and a resource control unit 380.

A CCTV video service providing server 300 according to an embodiment of the present invention or another server (not shown) operating in conjunction with the CCTV video providing server 300 transmits a CCTV video service application, a program, a web page, 200 to the user terminal 100, the user terminal 100 can install or open an application, a program, a web page, and the like for the service. Also, it may be driven in the user terminal 100 by using a script executed in the web browser. Here, a web browser is a program that enables a WWW (World Wide Web) service, and is a program for receiving and displaying hypertext described in hypertext mark-up language (HTML), for example, Netscape (Netscape) An Explorer, chrome, and the like. Further, the application refers to an application on the terminal, for example, an app (app) running on a mobile terminal (smart phone). An app can be downloaded and installed from the mobile app marketplace, a virtual marketplace where mobile content can be bought and sold freely.

At least one CCTV 400, at least one cloud server 500 and at least one NAS server 600 may communicate with each other through the network 200. In this case, the user terminal 100, the CCTV video service providing server 300, Generating the connection to the network 200 means that the CCTV video service providing server 300 creates a communication object at the communication contact for communication with the terminal connected to the network 200 . The CCTV video service providing server 300 can exchange data with each other through the communication object.

The first receiving unit 310 can receive an image from at least one CCTV 400. [ Here, at least one CCTV 400 may be an IP camera or a network camera, and may be monitored and controlled by the user terminal 100 through Internet-based communication. Here, the first receiver 310 may receive H.264, which is an international standard video transmission technology, when receiving an image from at least one CCTV 400, and may receive MJPEG, a compression technique for video transmission of the international standard Can be used.

The storage unit 320 may distribute the received images to at least one cloud server 500 and store the distributed images. At least one of the cloud servers 500 stores and records video data transmitted from the CCTV video service providing server 300. When the video data is accumulated, the at least one cloud server 500 may additionally be connected in parallel for distributed storage of video data. have. At least one NAS server 600 may store and record video data transmitted from at least one CCTV 400 via the CCTV video service providing server 300 in the same manner as the at least one cloud server 500 When the image data is accumulated, the image data can be additionally connected in parallel for distributed storage of the image data. That is, the CCTV video service providing server 300 is interlocked with at least one cloud server 500 and at least one NAS (Network Attached Storage) server, and distributes the received video images to at least one cloud server 500 When the image received from and stored in at least one CCTV 400 exceeds a preset amount of data, the image may be distributed and stored in at least one NAS server 600 connected in parallel.

The second receiving unit 330 may receive a request event requesting the video of at least one CCTV 400 from the user terminal 100. Here, when the second receiving unit 330 receives a request event requesting an image of at least one CCTV 400 from the user terminal 100, the second receiving unit 330 receives a request event of the image input from the user terminal 100 However, the request event may be received by a predetermined definition. For example, when a predetermined motion is detected in any camera designated by the user terminal 100, when the user terminal 100 is set to transmit an image to the user terminal 100, The second receiving unit 330 may generate an event such that the request event is received directly from the user terminal 100. [ For example, if there is a person who executes two-arm motion in Y CCTV of Yeoksam-dong, Gangnam-gu, Seoul, and the user has set to inform the user terminal 100, When a person to be executed is photographed, a trigger signal is generated and the image can be transmitted to the user terminal 100. Accordingly, when a trigger signal is generated in the predetermined motion detection area of at least one CCTV 400 from the user terminal 100, the second receiver 330 transmits the video to the user terminal 100 And when a trigger signal is generated in a predetermined motion detection area of at least one CCTV 400, it can be assumed that a request event is generated in the user terminal 100. [

The determination unit 340 can grasp the computing resources of the user terminal 100 in response to the received request event. That is, the user terminal 100 may require screens having different configurations according to purposes and intentions that require images. For example, in the case of real-time sightseeing relay, A local government may want only relay, and B local government may want to construct a screen to download a publicity booklet. In addition, there are customers who want only simple relaying, but there may be a customer who wants to record, or a customer who wants to reproduce recorded video. Since it is not possible to extinguish various requests to a fixed screen frame and it is also inefficient to develop a separate screen module according to various demands, a method of providing a CCTV video service according to an embodiment of the present invention is a method of providing a CCTV video service, Each module is standardized so that it is on the screen, and the system can recognize it and configure the screen.

For this, a presentation framework module may be used, and the presentation framework module may include a video service module, an additional service module, a service presentation configurer, a service definer configurator, and a screen definition configurator. Here, the video service module may be modularized into a video output module, a CCTV control module, and a recording and storing module in order to provide a video service to the user terminal 100. That is, the video service module may include a video output module, a CCTV control module, and a recording and storing module. The supplementary service module may provide additional services for providing the supplementary services to the user terminal 100 other than the video service. For example, the supplementary service module may include a shopping mall module, an SMS module, a chat module, and a 119 module. The service presentation configurator configures the service presentation provided by the video service module and the supplementary service module according to predetermined data in the service definition creator so as to be suitable for the intention of the user terminal 100 . In addition, the service definition creator may define and provide detailed information about the video service and the supplementary service to be provided to the user terminal 100. In other words, a screen for providing to the user terminal 100 can be defined and provided in advance. At this time, the screen definition organizer may support various client screens in response to a request for screens of different configurations for each service type according to a user's intention. For example, the user terminal 100 may output a screen using a smart phone or a smart pad in addition to the PC. At this time, when the Internet browser is used, only a part of the screen can be seen, and when a specific function is selected, the screen must be moved, and the movement of the screen may be limited. In addition, smartphones may have limited functionality and performance due to differences in screen size or operating method. In order to provide a consistent user screen in these various client environments, various client channels must be integrated and managed. Thus, the channel integration template framework module may include at least one template module, an output screen reconstructor, and an execution screen definition constructor. At least one template module may be pre-set corresponding to the characteristics and types of the user terminal 100. At this time, the at least one template module may include a web browser template module and a client environment template module. The Web Browser Template module includes the Microsoft Exploer Template module, the Google Chrome Template module, Apple's Safari Template module, Mozilla Firefox Template, Modules. The client environment template module may include an iPhone Template module, an Android Template module, a Win Mobile Template module and a sea template module.

The output screen reconstructor may reconfigure and define the output screen using the template definition module based on the screen definition configurator provided in the presentation framework template module and the client terminal information according to the user terminal 100. Execution Screen Definition Constructor can define the execution screen for the output screen reconstructed by the output screen reconstructor. For example, the channel integration template module may be a template module for reconstructing a screen definition according to the characteristics of each client. For example, it is possible to output a high-resolution image on a PC. However, There are many cases that can not be accommodated. Therefore, in order to output the screen to the smartphone, the image size must be reduced or the user terminal 100 must provide an additional function to control it. Also, the size and position of the function button must be changed according to the characteristics of the client. Therefore, the channel integration template module can perform the function of converting the screen output details defined in the screen definition organizer according to each individual client, and in order to efficiently perform the functions, , Unsupportable functions, and replaceable functions. For example, client environments such as MS Exploer, Google Chrome, Apple Safari, and Mozilla Firefox, as well as iPhone, Android, and Win mobile, are being upgraded irregularly according to each company's schedule. Since the screen configuration can not be continuously modified every time it changes, it is possible to actively cope with the change using the channel integration template module.

The conversion unit 350 may convert at least one CCTV 400 image to correspond to the identified computing resources. The conversion unit 350 reconfigures the screen using a predefined template corresponding to the identified computing resources, grasps the network resources of the user terminal 100, and transmits the CCTV video service providing server 300 and the user The network bandwidth and the network congestion of the channels formed between the terminals 100 and the at least one CCTV 400 image reconstructed based on the computing resources can be transcoded.

The transmitting unit 360 may transmit the converted image to the user terminal 100.

The control unit 370 may receive a control signal for controlling at least one CCTV 400 from the user terminal 100 and may control the rotation, tilting and zooming of at least one CCTV 400 based on the received control signal. And transmit the video of at least one CCTV 400 controlled in response to the control signal to the user terminal 100. [ Accordingly, when the user terminal 100 wants to view an arbitrary area at an arbitrary point, it controls at least one CCTV 400 through the user interface of the user terminal 100, ). At this time, the converting unit 350 can recognize the transcoding of the computing resources and the network resources of the user terminal 100, and can also perform the transcoding based on the computing resources and the network resources The transcoding method and the compression ratio can be set differently.

The resource control unit 380 can grasp the available resources held by each of the at least one cloud servers 500 and collects burden information for each available resource for each of the at least one cloud servers 500, It is possible to calculate the sum-burden information, which is the sum of the burden information for each resource, and calculate the burden ratio of the burden information for each available resource. The resource control unit 380 can adjust the resources required for each available resource according to the burden ratio. That is, the burden information for each available resource is calculated based on a value obtained by subtracting an allocated resource for one available resource from a requested resource for one available resource, and the requested resource is received from at least one CCTV 400 And the burden information according to available resources includes computing burden information and networking burden information, and the requested resources according to available resources may include computing request resources and networking request resources. At this time, when the resource control unit 380 adjusts the requested resources, the requested resource is adjusted in the order of the available resources having a high burden ratio, lightweight transcoding is performed to generate low compression high capacity contents, or high compression low capacity contents are generated Weight transcoding can be performed.

Here, the high compression low capacity stream refers to a flow of content that has undergone weight transcoding, which is performed when the computing resources are relatively high, while the capacity is reduced as the compression rate of the content is high. Here, the weight means that the higher the compression ratio based on the computing resource, the more computing resources are used, so that the computing resource is used more frequently.

The low compression high capacity stream refers to the flow of lightweight transcoded content that is performed when the computing resource is relatively low compared to the networking resources being relatively high since the capacity increases as the compression rate of the content is low. Here, the lightweight means that as the compression ratio is low based on the computing resources, less computing resources are used, which means that less computing resources are used.

The content quality may be a quality determined according to specifications, specifications, etc. of the user terminal 100, or a quality set by the user. For example, the quality of the content that can be received by the user terminal 100 is HD (High Definition). If the quality set by the user is set to Full HD, the quality may be determined based on the low quality HD . Or, if the quality set by the user is lower than the quality determined according to the specification or the like, the quality set by the user may be prioritized. On the contrary, if the quality set by the user is higher than the quality determined according to the specification or the like, the user terminal 100 can not reproduce the content with the resolution of the quality set by the user, so that the content quality can be set based on the low value.

In addition, the CCTV video service providing server 300 processes the service request from the user terminal 100 and transmits the video stream to the user terminal 100 when the real time video request is received from the user terminal 100 And a Front-End Server (not shown). At this time, if a plurality of front end servers are provided, the L4 switch can be connected to each other, and the L4 switch can connect the IP and the port to the user terminal 100 connecting to the front end server.

A method of providing a CCTV video service having the above-described configuration will be described in detail with reference to FIG.

(a) When requesting a real time image from the user terminal 100, the CCTV image service providing server 300 requests the image from at least one CCTV 400 and receives the image in response to the request. At this time, the CCTV video service providing server 300 can allocate a static IP of at least one CCTV 400 as a fixed IP. (B) The CCTV video service providing server 300 can grasp the computing resources and the networking resources of the user terminal 100 and can start screen reconstruction and transcoding. (C) In the user terminal 100, When streaming is desired, the CCTV video service providing server 300 can transmit data for downloading. Here, the CCTV video service providing server 300 may perform transcoding so that the N-screen is available in the user terminal 100. [ Alternatively, at least one cloud server 500 and at least one NAS server 600 may be connected to the user terminal 100 to request images of various formats for the N screen and may be stored in the user terminal 100 without a process At least one cloud server 500 and at least one NAS server 600 (not shown) via the user terminal 100 so as to share images with a TV, a PC or a tablet for the N screen directly with the user terminal 100 As shown in Fig.

(D) When a video is transmitted from at least one CCTV 400, the CCTV video service providing server 300 transmits the available resources of at least one of the cloud server 500 and the at least one NAS server 600 And then stored so as to be distributed based on the burden information. (E) When receiving a control signal from the user terminal 100, the CCTV video service providing server 300 transmits a control signal to a specific CCTV 400 in a desired area of the user terminal 100, It can be transmitted in real time in the user terminal 100 to be streamed. When a trigger signal is generated from at least one CCTV 400, a video received from at least one CCTV 400 is transmitted to the CCTV video service providing server 300, As shown in FIG.

The CCTV video service providing method of FIG. 2 and FIG. 3 is not described. The CCTV video service providing method of FIG. 1 can be easily derived from the same or the same description as the CCTV video providing method. Omit it.

FIG. 4 is a diagram illustrating a process in which data is transmitted and received between the respective components included in the CCTV image service providing system of FIG. 1 according to an embodiment of the present invention. Hereinafter, an example of a process of transmitting and receiving a signal according to an embodiment of the present invention will be described with reference to FIG. 4. However, the present invention is not limited to this embodiment, It is apparent to those skilled in the art that the process of transmitting and receiving the shown data can be changed.

Referring to FIG. 4, the CCTV video service providing server 300 receives an image from at least one CCTV 400 (S4100) and stores the received video in at least one cloud server 500 and at least one (S4200), and receives a response from at least one of the cloud server 500 and at least one NAS server 600 (S4210).

Then, the CCTV video service providing server 300 can transmit to the user terminal 100 without storing in the case of real-time streaming, and at least one cloud server 500 and at least one NAS server (Step S4300). At this time, at least one cloud server 500 and at least one NAS server 600 store images received from at least one CCTV 400 (S4400).

When the CCTV video service providing server 300 requests the CCTV video service providing server 300 from the user terminal 100 in step S4500, the CCTV video providing server 300 determines networking resources and computing resources of the user terminal 100 (S4600).
