The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part is said to "include" a certain component, it means that it can further include other components, without excluding other components unless specifically stated otherwise. Also, the term "part" or the like, as described in the specification, means a unit for processing at least one function or operation, and may be implemented by hardware, software, or a combination of hardware and software.

First, the analog CCTV and digital CCTV will be briefly described.

6A and 6B are diagrams for explaining the difference between analog CCTV and digital CCTV.

Currently, CCTV is changing from analog to digital, and digital CCTV is rapidly expanding its market share as the price and the price decrease with the rapid development of resolution and transmission speed compared to the past. Digital CCTV is basically the same principle as a webcam (PC) of a PC, and the program of the PC can be viewed as an integrated device installed inside the webcam. Digital CCTV is a type of IP camera that operates based on IP (Internet Protocol) addresses, and is often called a network camera. Digital CCTV is analogue CCTV, as shown in Figure 6a, unlike that connected to the recording equipment can be connected to a PC or operated independently, the scope of application can be extended to a variety of applications beyond the surveillance function of the existing CCTV have. In addition, the limit of monitoring by CCTV, which was limited internally, is extended to the outside through internet-based communication, so that anytime, anywhere monitoring and various services using CCTV or IP camera can be used.

Most current IP (Internet Protocol) cameras support their own web server functions, and they can be monitored and controlled by accessing IP cameras from the outside. However, it is not easy for general users to use it because it lacks expertise, and there is a problem in that even if it is used, services other than simple real-time monitoring cannot be provided.

Therefore, the real-time video service system according to an embodiment of the present invention serves as an intermediate connector that can use a wider range of IP cameras by providing a variety of services to users. In addition, it is intended to expand image-based social services by connecting various image information and user information that are additionally generated through the role of an intermediate connector.

In other words, in order to make use of the features of IP cameras and to expand their use in various application fields, a real-time video service system using IP cameras is constructed, and IP cameras, software, servers, terminals, etc. are used in existing standards and markets. It can support various technologies that are integrated.

On the other hand, Figure 7 is a view for explaining the concept of a service provided in the real-time video service system according to an embodiment of the present invention.

Real-time video service system 200 according to an embodiment of the present invention provides a real-time video service and is implemented as a portal website, a service that extends the existing video services, such as YouTube (), Pandora TV (()) to the real-time area Unlike Africa's private broadcasting service, which seeks real-time Internet broadcasting for general users, it provides specialized services that meet the needs and needs of specific customer groups.

The biggest difference from the existing real-time Internet broadcasting is that the closed service (100a, 100c) and the open service (100b) can be provided to the user terminal (300a, 300b, 300c) and the communication function provided by the IP camera It is an interactive service that allows the user to control the camera directly. That is, the user can control the IP camera controlling the specific IP camera to rotate and zoom the camera in real time from a remote location. Through this, the user can monitor the specific place in real time through various real-time images that he / she wants. Such real-time monitoring is based on internet communication, and it can be used not only in PC but also in smartphone terminals such as iPhone and Google phone, so that users can use the service in ubiquitous environment beyond local restrictions.

In addition, various additional services may be provided in addition to basic monitoring by providing various additional services according to a user's intention of using the apparatus. These various additional services can be selected and used by the user, and for this purpose, the system is constructed to provide a customized service for each user group.

Real-time video service according to an embodiment of the present invention can see a service of a similar nature as the existing video service, but there are many differences in content. Since the real-time video service according to an embodiment of the present invention has a small burden on equipment such as a storage medium, and a user for a specific purpose such as monitoring and monitoring, as a main target customer, a self-importation source can be secured by charging them a fee. It can solve the management difficulties that existing video service companies are facing.

Features of the existing video service and the real-time video service according to an embodiment of the present invention are shown in Table 1 below.

On the other hand, the real-time video service according to an embodiment of the present invention is a service for real-time relaying the image of the IP camera to the user terminal. Therefore, it does not need a large storage medium like the existing video service. This means that there is no need for continuous facility investment, which is a problem of the existing video service. In addition, a real-time video recording service that requires a storage medium corresponds to users who use the service for a special purpose. For example, services such as greening of CCTVs are required according to the business purpose of individual operators, so they operate for a fee, unlike services for general consumers, and are intended for corporations or individual operators. It is easy to secure profitability. In the real-time video service according to an embodiment of the present invention, by charging a recording service, the cost for equipment investment such as a storage medium is covered by the revenue generated from the service, and the deterioration of profitability like the existing video service can be excluded. have. Most internet services use advertising revenue as a main source of income, and the real-time video service according to an embodiment of the present invention uses user fees paid by users (individuals or corporations for business purposes, not general consumers) rather than advertising revenue. Business stability can be secured early. For example, the real-time video service according to the embodiment of the present invention can be used for kindergarten and the like.

11 is a diagram illustrating a presentation framework module in a real-time video service system according to an embodiment of the present invention.

First, the presentation framework module 410 is to configure a variety of real-time video services to suit the user's intention. In the existing aspect services such as YouTube, all images are provided in a uniform form according to the screen configuration predefined by the service operator. However, the real-time image according to the embodiment of the present invention may require a screen having a different configuration for each service type according to the intention and purpose of the user using the same.

For example, in the case of real-time relay of tourist destinations, the local government A may only want a simple relay, and the local government B may want to configure the screen to download the brochure. In addition, some customers want only a simple relay, but some may want to record or some may want to play back recorded video. In the case of a shopping mall, various demands of the shopping mall operator may occur. There is a limit to digesting these various needs into a fixed screen frame. In addition, it is inefficient to develop a separate screen module according to the needs of each customer. The presentation framework module 410 standardizes each module so that various additional services to be provided along with real-time image information are on one screen, and supports a service for generating a screen definition that the system can recognize and configure the screen. Framework module. Through this, the real-time video service system according to an exemplary embodiment of the present invention can actively provide a screen and a function desired by a customer by avoiding a uniform screen and a function.

Referring to FIG. 11, in the real-time video service system according to an exemplary embodiment of the present invention, the presentation framework module 410 may include a video service module 411, an additional service module 412, a service presentation constructor 413, And a service definition configurator 414 and a screen definition configurator 415.

The video service module 411 provides a video service for providing to the user terminal by modularizing it into an image output module, a CCTV control module, or a recording and storage module. That is, the image service module 411 may include an image output module, a CCTV control module, a recording and storage module, and the like.

The supplementary service module 412 modularizes and provides supplementary services for providing to the user terminal other than the video service. For example, the additional service module 412 may include a shopping mall module, an SMS module, a chat module, a 119 module, and the like.

The service presentation configurator 413 may predefine the service presentation provided by the video service module and the additional service module according to the contents defined in the service definition configurator to suit the intention of the user terminal. Configure.

The service definition configurator 414 defines and provides details about the video service and the additional service to be provided to the user terminal.

The screen definition composer 415 defines and provides a screen for providing to the user terminal in advance. In this case, the screen definition configurator 415 supports various client screens in response to a screen having a different configuration for each service type according to a user's intention. Another reason for introducing the concept of the screen definition of the screen definition configurator 415 is to efficiently support various client screens. For example, in addition to PCs, the use of smartphones has been increasing rapidly since the advent of the iPhone. However, since smartphones are smaller than PC screens, the use of conventional screens is inconvenient. If you use the Internet browser, you can see only a part of the screen, and if you select a specific function, the screen must be moved, but the screen movement may be limited. In addition, the smart phone may have limitations in functions and performance provided according to differences in screen sizes or operation methods. In order to provide a consistent user screen in such various client environments, various client channels must be integratedly managed.

In addition, in order to efficiently support smartphones, it would be inevitable to provide a client for smartphones. Currently, the smartphones widely used or expected to be used are iPhone, Google Phone (Android Phone) and Microsoft's Windows Mobile Phone. It is widely used, and recently, Samsung Electronics' seaphone and symbian. Clients for smartphones must be developed independently according to their characteristics. For example, the iPhone is not allowed to multitask, but the Google Phone is multitasked. As a result, the features and development methods that the client can provide may also vary. However, the same service function should be provided in all clients so that various users can use the service with the same feeling. The service functions provided by the real-time video portal according to the embodiment of the present invention are described in the screen definition configurator 415 which defines the service module available in the presentation framework module 410 and the output module.

12 is a diagram illustrating a channel integration template framework module in a real-time video service system according to an embodiment of the present invention.

Referring to FIG. 12, in the real-time video service system according to an exemplary embodiment of the present invention, the channel integration template framework module 420 includes at least one template module 422, an output screen reconstructor 423, and an execution screen definer. 424 may be included.

At least one template module 422 is pre-formed in relation to the characteristics and types of the user terminal. Here, the at least one template module 422 includes a web browser template module and a client environment template module, wherein the web browser template module is a Microsoft Explorer template module of Microsoft Corporation and a Google Chrome template of Google Corporation. Chrome Template module, Apple's Safari Template module and Mozilla's Mozilla Firefox Template module. The client environment template module includes an iPhone template module and an Android template. Module), a Win mobile template module, and a sea template module.

The output screen reconstructor 423 uses the template definition module 422 preformed according to the screen definition configurator 415 provided by the presentation framework module 410 and the client terminal information 421 according to the user terminal. To reconfigure and define the output screen.

 The execution screen definition configurator 424 defines an execution screen for the output screen reconstructed by the output screen reconstructor 423.

Specifically, the channel integration template module is a template module for reconfiguring the screen definition according to the characteristics of each client. For example, a PC can output high resolution video, but smartphones cannot accommodate screen sizes. Therefore, in order to output the screen to a smartphone, it is necessary to convert the image size to a small size or provide an additional function for the user to control it. In addition, the size and position of the function button should also change according to the characteristics of the client. Therefore, the channel integration template module converts the screen output details defined in the screen definition composer to each individual client. In order to perform this efficiently, it must be reconfigured by dividing it into a function that can be supported, a function that cannot be supported, and a function that can be replaced in consideration of the characteristics of all supported clients.

For example, client browsers such as iPhone, Android, and Win mobile, as well as web browsers such as MS Explorer, Google Chrome, Apple Safari, Mozilla Firefox, etc. are being upgraded on a regular basis. Continually modifying the screen configuration as each client's environment changes requires a lot of effort and cost. Therefore, the channel integration template module can reduce these efforts and costs, and enable the real-time video portal service to respond to the market more proactively. In this regard, the channel integration template module is an essential technology for providing services in a rapidly changing market situation.

From the developer's point of view, the channel integration template module can reduce the development effort considering the characteristics of each client when developing the module for the individual client. In other words, since the development proceeds faithfully to the predefined screen, there is no need to consider compatibility and consistency with other clients. This can contribute to the continuous development of services.
