The present invention relates to a video control method and system using a CDMA 2000 1x EV-DO system in ubiquitous communication.

It is a technology to make a user's convenience by connecting various devices such as doors, refrigerators, washing machines, etc. which are located in a general home, office, building, etc. to each other and interworking with various external networks. Quarterly communication (Ubiquitous Network) is emerging.

Ubiquitous is called `` Ubiquitous Computing '' because it puts computers that correspond to their roles in everyday things so that things communicate with each other.It is called `` Ubiquitous Computing ''. It can also mean an environment that can be freely connected to the network regardless of its type.

Ubiquitous may control the various devices in the home from the outside through the Internet, or control the various devices on / off through the mobile communication network using a mobile terminal.

1 is a block diagram showing a home appliance control system using a conventional mobile terminal.

Conventional home appliance control system 100 is connected to the first to n-th home appliances (110,120,130,140), the first to n-th home appliances (110,120,130,140) in a wired or wireless interface to a plurality of home appliances in accordance with the control signal input from the outside Fixed terminal 150 for controlling the mobile terminal 170, the mobile terminal 170 for wirelessly transmitting control signals for a plurality of home appliances (110, 120, 130, 140) through a wireless communication network, and the mobile terminal 170 through a wireless communication network Under the control of the wired / wireless portal site 160 for transmitting a control signal for the home appliance (110, 120, 130, 140) over the wired communication network to the fixed terminal 150.

In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

In order to facilitate understanding of the present invention, the concept of the present invention is first outlined.

According to the present invention, a small camera is installed in a living room, a home room, a children's room, etc., and is connected to a communication network such as a mobile communication network or the Internet. It is to receive and confirm the situation of the home in real time by operating.

In addition, the ubiquitous management server connected to the home network control device that controls the small camera through a communication network controls the small camera at a predetermined time, photographs the living room, the main room, and the children's room, and stores them as a video. When the home video is requested, the user transmits the video of the place to the hybrid mobile terminal, thereby confirming the home situation by displaying the video through the hybrid mobile terminal.

In addition, the home network control device of the home has an IP address, and the user connects directly to the home network control device of the home using the wireless mobile terminal by using a hybrid mobile terminal, and operates a small camera for the place to be monitored. The situation of the place is received by checking the video.

In addition, a small camera is installed in each department of the company as well as at home, and the president or manager can check and view the status of each department as a moving image using a hybrid mobile terminal.

In the present invention, a CDMA 2000 1x EV-DO system is used to transmit a video captured by a small camera in a place where surveillance is required as described above to a mobile terminal carried by a user through a mobile communication network. It is a hybrid mobile terminal having a function of receiving and displaying. Hereinafter, a description will be given of an embodiment of the present invention after describing a CDMA 2000 1x EV-DO system for transmitting a video to a hybrid mobile terminal.

Mobile communication systems that provide wireless communication services to mobile subscribers are developed through first generation analog AMPS (Advanced Mobile Phone Systems) and second generation cellular (PC) / Personal Communication Services (PCS). Recently, the third generation high speed data communication, IMT-2000 (International Mobile Telecommunication-2000) has been developed and commercialized.

IMT-2000 is a global multimedia mobile communication service with integrated wired / wireless concept that can send and receive voice, data, and video at high speed in one wired and wireless environment. It is a new personalized third generation (3G) service that allows users to use the service with a single terminal or user access card anywhere in the world. IMT-2000 becomes global roaming by using global standardization and same frequency, and it is possible to multimedia communication such as high quality voice, internet and video.

The IMT-2000 service may be classified into a Code Division Multiple Access (CDMA) 2000 1X service and a CDMA 2000 1x Evolution Data Optimized (EV-DO) service.

CDMA 2000 1X (hereinafter referred to as '1X') service is 14.4 Kbps, which is the speed supported by the existing IS-95 A / B network using the IS-95C network evolved from the existing IS-95A and IS-95B networks. It is a service that enables wireless Internet at up to 144 Kbps, much faster than 56 Kbps. Accordingly, the mobile communication system is capable of providing various multimedia services (AOD, VOD, etc.) as well as improving existing voice and wireless application protocol (WAP) service quality through 1X service.

Meanwhile, the CDMA 2000 1x EV-DO (hereinafter referred to as 'EV-DO') service is a high data rate (HDR) technology, which is developed by Qualcomm using CDMA technology. It is a new technology of packet wireless data transmission and enables mega high speed data transmission. The transmission speed is 2.4 Mbps in the forward direction and 307.2 Kbps in the reverse direction. This service is implemented in the same wireless system as the ADSL method used in the wire.

Hereinafter, for convenience of description, the CDMA 2000 1X system will be abbreviated as "1X system" and the CDMA 2000 1x EV-DO system "as" EV-DO system ".

In the current mobile communication system, the EV-DO system is used interchangeably with the existing 1X system. That is, the EV-DO system and the 1X system are installed at the same time in one wireless base station or base station controller, but operations are performed separately. In other words, the base station transmitter is provided with a channel card for the EV-DO system and a channel card for the 1X system, respectively. The base station controller also includes a data processing board for processing packet data to be transmitted and received with the EV-DO system and a data processing board for processing data to be transmitted and received with the 1X system. Therefore, when multimedia data is transmitted from a mobile communication system such as a wireless base station or a base station controller to a mobile terminal, the multimedia data is transmitted at high speed to the EV-DO system, and low speed data such as voice or data is transmitted to the 1X system.

2 is a configuration diagram schematically showing the configuration of a ubiquitous communication system according to an embodiment of the present invention.

The ubiquitous communication system 200 according to the embodiment of the present invention includes a hybrid mobile terminal 210, a base station transceiver subsystem (BTS) 220, a base station controller (BSC) 230, and a mobile station. Mobile Switching Center (MSC) 240, Packet Data Serving Node (PDSN) (hereinafter referred to as PDSN) 250, IP (Internet Protocol) network 260, ubiquitous management server 270 ), A ubiquitous database 272, a home network controller 280, and a plurality of cameras 292, 294, 296, 298, and the like.

The base station transmitter 220 and the base station controller 230 constituting the wireless base station in the mobile communication network includes a 1X transmitter 222 and a 1X controller 232 in a configuration for transmitting voice signals, and also transmits multimedia data. The configuration includes an EV-DO (Access Network Transceiver Subsystem) 224 and an EV-DO (ANC) Access Network Controller (ANC) 234.

Here, the IP network 260 is connected to the client computer 262 for setting the details of the video control ubiquitous service by the user connected to the ubiquitous management server 270 over the Internet.

The ubiquitous management server 270, when the hybrid mobile terminal 210 is connected to the wireless Internet, provides a plurality of menus for the video control ubiquitous service, including service subscription, service setting, video viewing, etc. in the form of a phone page. If the hybrid mobile terminal 210 selects to watch the home video, the sub-video viewing menu for the home, the living room, and the bedroom is provided. If the random mobile video selection menu is selected by the hybrid mobile terminal 210, the IP network is selected. The video request command is transmitted to the home network controller 280 through the home network controller 280. Then, the video shot from the home network controller 280 is captured by the IP network 260, the PDSN 250, and the EV-DO. Control to be transmitted to the hybrid mobile terminal 210 via the controller 234 and the EV-DO transmitter 224.
Here, the ubiquitous management server 270 may encode the video received from the home network control device 280 into packet data, and then generate and store the functional content, or provide the same to the hybrid mobile terminal 210. In this case, the functional content may have the form of media data, a playback program, a resource, user addition data, and a management program. The media data is the recorded video, the playback program is the program that plays the video, the resource is the resource related to the video playback, the user addition data is the additional description edited by the user, and the management program is the production date and distribution date of the video. Program to manage events, etc. In addition, the resources include subtitle information, lyrics information, explanatory material, and summary / plot information.

In addition, the ubiquitous management server 270 transmits a video request command to the home network controller 280 every predetermined time according to the user's video control ubiquitous service settings, and thereafter a predetermined time for each place from the home network controller 280 For example, one minute of the received video is stored in the storage space allocated to the user ID of the ubiquitous database 272. In addition, when the hybrid mobile terminal 210 accesses the video request for the place, the ubiquitous management server 270 reads the video data of the place from the ubiquitous database 272, and the IP network 260 and the PDSN. Reference numeral 250 provides an EV-DO controller 234 and an EV-DO transmitter 224 to the hybrid mobile terminal 210.

Among the many menus for the video control ubiquitous service, the video viewing menu is a home video menu for watching the internal situation of the home as a video, an office video menu for watching the company's situation as a video, and watching a video such as a park or outdoors. Outdoor video menus, and the like.

The ubiquitous database 272 stores subscriber information on the ID, password, terminal number, etc. of the subscriber who subscribed to the video control ubiquitous service, and setting contents on the video control ubiquitous service set by the subscriber. Video data of each place received from the control device 280 is stored corresponding to the subscriber ID or the terminal number.
The ubiquitous database 272 stores not only video data but also functional content in the form of media data, a playback program, a resource, user addition data, and a management program.

On the other hand, the hybrid mobile terminal 210 is a mobile communication terminal that can accommodate both communication services provided by the EV-DO system and the 1X system. The hybrid mobile terminal 210 wirelessly accesses the ubiquitous management server 270 to set up a video control ubiquitous service, or selects and requests a video for a situation of a home or office of a user, and requests the ubiquitous management server 270 or home. A video data received from the network controller 280 through the EV-DO system is displayed.                     

In addition, the hybrid mobile terminal 210 periodically monitors two systems, 1X system and EV-DO system, at regular time intervals. That is, in the operating state of the 1X system that does not use the EV-DO system, the hybrid mobile terminal 210 periodically searches for the EV-DO system in the middle of communicating with the 1X system, and performs EV in traffic using the EV-DO system. Periodically scan the 1X system in the middle of communicating with the DO system.

For example, in a traffic state with the EV-DO system, the hybrid mobile terminal 210 responds to a call signal such as a voice call connection signal or a short message that may be transmitted from the 1X system, and periodically registers its location with the 1X system. It connects to 1X system and updates system resource such as system message, access message. Accordingly, the hybrid mobile terminal 210 is provided with a voice signal transmission service and a low-speed data transmission service through the 1X system, and provides a high-speed data service such as a music data stream or a video or a video through the EV-DO system. In order to receive both systems, a hardware configuration corresponding to each of the two systems is provided, but the two components operate independently of each other. Hybrid mobile terminal 210 having such a complex function and configuration is generally set to switch to the 1X mode to communicate through the 1X system in the standby state waiting for communication, to check whether the data received by the EV-DO system For this reason, the controller switches to EV-DO mode at regular intervals and then returns to 1X mode. Here, the 1X mode may be referred to as a general communication mode, and the EV-DO mode may be referred to as a multimedia mode.

The switch function between the 1X system and the EV-DO system is handled by software installed in a mobile station modem (MSM) chip, which is a kind of baseband modem embedded in the hybrid mobile terminal 210, and is controlled by hardware. This is accomplished by tracking the frequencies used in both systems by means of a searcher connected to the MSM chip. That is, when the hybrid mobile terminal 210 switches from the EV-DO system to the 1X system, the servo module tracks and switches the frequency used by the 1X system under the control of the MSM chip, and switches from the 1X system to the EV-DO system. When switching, it tracks and switches the frequency used by the EV-DO system.

In the EV-DO mode, in case of a forward link for transmitting multimedia data such as a video from the EV-DO system to the hybrid mobile terminal 210 via an access network (AN), time division multiple access (TDMA): In the case of the reverse link that allows a large amount of messages to be transmitted using a time division multiple access method and transmits data from the hybrid mobile terminal 210 to the EV-DO system via an access network (AN). In order to accommodate a large number of subscribers, code division multiple access (CDMA) is used.

In addition, the hybrid mobile terminal 210 switches to the 1X mode at regular intervals to check whether there is an incoming voice signal in the 1X mode while receiving multimedia data from the EV-DO system in the EV-DO mode. Returns to the EV-DO mode again.

The 1X transmitter 222 and the EV-DO transmitter 224 as the base station transmitter 220 provide a mobile communication service for transmitting a voice signal or multimedia data to the hybrid mobile terminal 210 through an air interface. to provide. For example, the 1X transmitter 222 provides voice or low speed data to the hybrid mobile terminal 210, and the EV-DO transmitter 224 mainly provides multimedia data or high speed data to the hybrid mobile terminal 210.

The 1X controller 232 and the EV-DO controller 234 as the base station controller 230 serve to control the mobile communication service of the base station transmitter 220. That is, the 1X controller 232 connects a plurality of 1X transmitters to the mobile switching center 240 to control transmission of voice or data, and the EV-DO controller 234 connects a plurality of EV- to control transmission of multimedia data. The DO transmitter is connected to the PDSN 250, which is a packet data network.

In particular, when there is a call connection request for multimedia data transmission from the hybrid mobile terminal 210, the EV-DO controller 234 fails in the EV-DO transmitter 224 or the EV-DO controller 234, and thus hybrid movement. If the call connection with the terminal 210 cannot be performed, the hybrid mobile terminal 210 stops the call connection to the EV-DO system by sending a connection deny message to the hybrid mobile terminal 210. Make a call connection to the system.

The mobile switching center 240 physically connects a plurality of 1X controllers 232 with another mobile switching center or a public switched telephone network (PSTN) 246, and a hybrid mobile terminal (PSTN). If there is a call connection request from 210, the communication connection path of the 1X system is switched and provided.                     

In addition, the mobile telecommunication switching center 240 includes a home location register (HLR) 232, which is a database storing information of mobile terminals registered with the mobile communication switch 240, and a mobile station within its service area. The mobile terminal obtains information of the mobile terminal from the visitor location register (VLR) 234, which is a database that stores information of the terminal, and processes the call of the subscriber.

EV-DO system as a packet data system for transmitting only data is coupled to PDSN 250 based on TCP / IP, and transmits and receives various data to and from IP network 260 in the form of IP packet (Internet Protocol Packet). . After receiving the packet data transmitted from the IP network 260 to the hybrid mobile terminal 210, the packet data is generated for the packet data service, for example, an MPEG packet, and the generated packet data is converted into the TDM scheme. It is loaded on the divided time slot and transmitted to the hybrid mobile terminal 210. The EV-DO system receives the CDMA modulated data from the hybrid mobile terminal 210, generates an IP packet based on the CDMA modulated data, and transmits the IP packet to the PDSN 250.

EV-DO systems are required to maximize throughput per sector and assign each user the highest data rate possible depending on the channel situation. Accordingly, the EV-DO system provides a multimedia service with maximum power when transmitting multimedia data to one hybrid mobile terminal 210 in one sector.

In the forward link in the EV-DO system, the base station transmits the maximum power capable of transmitting multimedia data without power control, and hard handoff is possible. In the reverse link, power control is performed for each hybrid terminal, and softer or soft handoff is possible.

The client computer 262 is connected to the IP network 260 by wire, such as a cable, the user is used to access the ubiquitous management server 270 over the Internet, and to set up his own video control ubiquitous service, For example, set a home video, a living room video, a bedroom video, a warehouse video, etc., and set up a one-minute video every five hours, or set a planning room, a general affairs department, a laboratory, a material department, etc. for one minute in real time. Is the terminal used to.

When the ubiquitous management server 270 receives a video request in real time from the hybrid mobile terminal 210, the ubiquitous management server 270 transmits the video of the place to the hybrid mobile terminal 210 in real time through the home network controller 280 of the subscriber. If the subscriber is set to shoot and store the place at a certain time, the subscriber controls the home network control device 280 of the subscriber at the set time to shoot the place and store it as a video in the ubiquitous database 272 will be. In more detail, the ubiquitous database 272 is stored in the ubiquitous database 272 as functional content in which playback programs, resources, user addition data, and management programs are added to the video data.

In addition, the ubiquitous management server 270 is a web language such as HTML (HyperText Markup Language), WML (Wireless Markup Language), etc., which allows a user of the hybrid mobile terminal 210 to use a website access or video control ubiquitous setting service. Operate web sites for wired and wireless access. Therefore, when the subscriber connects to the ubiquitous management server 270 through the wired internet network by using the client computer 262, the MIN of the hybrid mobile terminal 210 of the subscriber must be separately input. On the other hand, when the subscriber connects to the ubiquitous management server 270 through the wireless Internet network using the hybrid mobile terminal 210, the ubiquitous management server 270 is connected to its configuration data without having to input MIN separately. Store with the MIN of the mobile terminal 210. In this case, the ubiquitous management server 270 stores the MIN, configuration data, or connection request data of the subscriber station in the ubiquitous database 272 in a hierarchical manner. Thus, the ubiquitous management server 270 has an internet address (eg, www.homepicture.com) so that the client computer 262 can access the Internet.

In addition, the ubiquitous management server 270 provides a multimedia playback module (not shown) that allows a user to watch or display video data by the client computer 262 and the hybrid mobile terminal 210. Here, the multimedia playback module is a module that can edit and play functional content in the form of a playback program, resource, user addition data, and management program including video data provided by the ubiquitous management server 270.

The ubiquitous database 272 stores website information data or phone page information data provided by the ubiquitous management server 270 according to an embodiment of the present invention. Accordingly, the ubiquitous management server 270 provides the website information data or the phone page information data stored in the ubiquitous database 272 to the subscriber's client computer 262 or the subscriber's hybrid mobile terminal 110 as a web screen. . Ubiquitous database 272 may also be a relational database management system (RDBMS) such as Oracle, Infomix, Sybase or DB2, or Gemston, Orion or O2. An object-oriented database management system (OODBMS) and an XML Native Database such as Excelon, Tamino or Sekaiju can be implemented for the purposes of the present invention, and It has the appropriate fields or elements to achieve its functionality. Since the construction and management of the database required for the present invention can be easily carried out by those skilled in the art, detailed description thereof will be omitted.

The video data stored in the ubiquitous database 272 is downloaded from the client computer 262 through the WML (Wireless Markup Language) based data format for display in the hybrid mobile terminal 210 and the IP network 260. MPEG-based video data format for receiving and outputting or displaying.

On the other hand, the home network controller 280 is connected to the IP network 260 with an IP address, when receiving a video request command from the ubiquitous management server 270, a plurality of cameras (292, 294, 296, 298) It operates and encodes the video input from the cameras 292, 294, 296, and 298, and converts the video input into video data in the form of MPEG TS packets, for example, and transmits the video data to the ubiquitous management server 270. That is, the home network controller 280 generates the captured video as functional content having a form of media data, a playback program, a resource, user addition data, and a management program and transmits it to the ubiquitous management server 270.

The home network controller 280 uses IPv6 technology to connect to a broadband network with a unique IP address. IPv6 is a new Internet addressing system designed to overcome the existing shortage of the Internet, which consists of a 32-bit addressing system.It is composed of 128 bits, which is four times the existing addressing system. It allows you to give an independent address to every device on your network.

Many cameras (292, 294, 296, 298) are installed in homes, living rooms, bedrooms, warehouses, etc. in the case of homes, or in the corners of each department, such as accounting room, general affairs department, materials department, personnel department, etc. do. In addition, the plurality of cameras 292, 294, 296, and 298 are small cameras that photograph a subject and input the digital data to the home network controller 280.

3 is a configuration diagram schematically showing an internal configuration of a home network control apparatus according to an embodiment of the present invention.

As shown in FIG. 3, the home network controller 280 may include an encoder 310, a microcomputer 320, a network interface card (NIC) 330, a communication modem 340, a buffer 350, and the like. Has a configuration

The encoder 310 encodes audio and video signals input from the cameras 292, 294, 296, and 298 into file stream packets such as mpeg, asf, wmv, and wma. That is, the encoder 310 digitizes and compresses audio and video signals, generates an error correction code by using a Forward Error Correction method, and inserts the error correction code into the compressed multimedia data. The completed multimedia data is converted into a packet that can be transmitted through the Internet by the communication modem 340. In addition, the encoder 310 converts the input audio and video signal into functional content having a form of media data, a playback program, a resource, user addition data, and a management program and outputs the converted content.

The video converted into a file stream packet through the encoder 310 is buffered in a first in first out (FIFO) manner in a predetermined area of the memory 350.

The NIC 330 employs a transceiver capable of Carrier Sense Multiple Access / Collision Detection (CSMA / CD) to a network card to connect a plurality of information terminals in a home or building without a separate line configuration. Can be used.

The communication modem 340 configures a structure similar to 10 BASE-2 (Thin Net) which does not require a hub among the Ethernet structures. For reference, 10 BASE-2 uses CSMA / CD as a media access method for coaxial cable, and baseband differential Manchester coding as line coding. In addition, the IP datagram according to the IP protocol may be reconfigured into an Ethernet frame, and may also have a protocol structure of configuring data of the Ethernet frame into IP packets.

The memory 350 functions to buffer video data in a predetermined area or to store and store encoded video data.

4 is a screen illustrating a process of setting a video control ubiquitous service using a mobile terminal or a client computer according to the present invention.

As for the method of setting the video control ubiquitous service according to the present invention, the method of setting using the client computer 262 is similar to the process of setting through the Internet, and thus, sets the wireless Internet using the hybrid mobile terminal 210. How to do this is described.                     

First, the subscriber accesses the ubiquitous management server 270 through the wireless Internet using the hybrid mobile terminal 210.

When accessing the wireless Internet through the hybrid mobile terminal 210, the subscriber is connected to the wireless Internet access, such as "Nate", "ez-i", "magicⓝ" provided by each mobile carrier using a menu.

The text is displayed in the text or HTML (Hyper Text Markup Language) embedded in the terminal on the screen display (LCD) of the hybrid mobile terminal 210, the arrow using the direction keys of the keypad (Keypad) attached to the hybrid mobile terminal 210 Indicates that it is operated.

FIG. 4A is an initial access screen of a menu function appearing on the screen display of the hybrid mobile terminal 210, and FIG. 4B shows a user selecting web surfing in FIG. 4A. The case is shown. When the web surfing is selected, the user of the hybrid mobile terminal 210 is connected to a specific homepage selected by the user (eg, www.lg019.co.kr). 4C is a screen displayed on the screen display unit of the hybrid mobile terminal 210 when news / weather is selected in FIG. 4B, and FIG. 4C is FIG. 4C. In the case of selecting “ubiquitous” in step 10, the screen is displayed on the screen display unit of the hybrid mobile terminal 210 in FIG. This screen is displayed when is selected.

In this case, the time point at which the hybrid mobile terminal 210 is actually connected to the Internet may vary depending on necessity. That is, the user may be connected in the part of the user (a) (b) (c) (d) of FIG. 4 that actually needs to be connected to the Internet. For example, if web surfing is selected in FIG. 4A, a procedure for connecting to a specific Internet homepage set in the hybrid mobile terminal 210 may be performed. However, the screen displayed in FIG. This is because it is not a service that needs to be connected to the Internet. In addition, when the Chosun Ilbo No. 2 or the JoongAng Ilbo is selected in FIG. In (c) of FIG. 4, a connection procedure between the hybrid mobile terminal 210 and the Internet should be immediately performed according to a user's selection.

However, in the case of selecting “ubiquitous” No. 10 in FIG. 4B, in FIG. 4C, the Internet connection between the hybrid mobile terminal 210 and the ubiquitous management server 270 may not be necessary yet. Such an Internet connection does not need to be connected to the hybrid mobile terminal 210 and the Internet even in the case of FIG. That is, in the case of “ubiquitous”, when the user accesses to the IP address of the home network controller 280 using the hybrid mobile terminal 210 to perform necessary home video, home appliance or environment setting, home network control The device 280 provides the phone page as shown in FIG. 4C to the hybrid mobile terminal 210, and accordingly, the user selects an operation selection required, i.e., a selection menu in FIG. 4D. Accordingly, the home network controller 280 may perform a user's selection command.

Next, a video control method in ubiquitous communication according to an embodiment of the present invention will be described with reference to the flowchart shown in FIG. 5.

First, when a subscriber is located at a certain place while carrying the hybrid mobile terminal 210, the hybrid mobile terminal 210 performs location registration for a base station that manages the area where it is currently located, and then through the mobile communication network. There is a standby state to perform wireless communication. This location registration process is a well-known technique known in the art, so the detailed process is omitted.

Subscribers can directly access the home network control device 280 via the hybrid mobile terminal 210 via the wireless Internet to check their homes as a video, or select the "ubiquitous" menu through the wireless Internet connection to the ubiquitous management server ( 270) it is possible to check the status of his household.

The subscriber selects a ubiquitous menu among a plurality of menus basically provided by the hybrid mobile terminal 210 or a plurality of menus provided in the processes of FIGS. 4A and 4B by accessing the wireless Internet. When basically provided in the hybrid mobile terminal 210, the "ubiquitous" menu is a menu for accessing the IP address of the home network controller 280 installed in the subscriber's home through the wireless Internet.

When the "ubiquitous" menu is selected by the subscriber, the hybrid mobile terminal 210 transmits a radio access signal, and the transmitted radio access signal transmits the base station transmitter 220, the base station controller 230, and the mobile communication switching center 240. The data is converted into wireless access data through the IP network 260 and transmitted to the home network controller 280 through the IP network 260.                     

When the "ubiquitous" menu is selected in the wireless Internet connection state of the mobile carrier as shown in (a) or (b) of FIG. 4, the connection of the hybrid mobile terminal 210 is transferred to the ubiquitous management server 270. Of course, when the wireless Internet server and the ubiquitous management server 270 of the mobile carrier is the same, the hybrid mobile terminal 210 is connected to the ubiquitous management server 270 when the subscriber's wireless Internet access, accordingly, the ubiquitous management server 270 ) Provides an initial access screen as shown in FIG. 4A (S502).

When the subscriber selects the "ubiquitous" menu in the wireless Internet connection state or the hybrid mobile terminal 210 accesses the home network controller 280, the ubiquitous management server 270 or the home network controller 280 is a hybrid. The mobile terminal 210 provides a web page or a phone page for ubiquitous as shown in (c ') of FIG. 4 (S504).

The web page or phone page for ubiquitous includes the "Home Appliance" menu that controls the home appliances in the subscriber's home, the "Home Video" menu that controls the multiple cameras installed in the home, the "Home Appliance" menu, or the "Home Appliance" menu. It includes a "environmental settings" menu that sets the details for the "image" menu. In addition, it may include a menu for controlling an information device such as a computer or a TV in the home.

The subscriber selects a "home video" menu from a plurality of ubiquitous menus to check the appearance of the home (S506).

When the hybrid mobile terminal 210 selects the "home video" menu, the ubiquitous management server 270 selects a certain place in the home so that the subscriber selects a home video submenu, that is, as shown in (d) of FIG. 4. Submenus such as “living room”, “bedroom”, and “warehouse” are provided to the hybrid mobile terminal 210 (S508).

The subscriber operates the hybrid mobile terminal 210 to select, for example, a “living room” menu among a plurality of home image submenus (S510).

When the hybrid mobile terminal 210 selects the “living room” menu, the ubiquitous management server 270 reads the IP address of the home network controller 280 corresponding to the terminal number from the ubiquitous database 272, and then the IP address. The video request data for requesting a "living room" video is transmitted to the home network controller 280 installed in the subscriber's home through the IP network 260 (S512).

The home network controller 280 operates the second camera 294 installed in the living room of the subscriber's home based on the received video request data. The second camera 294 photographs the foreground of the living room and transmits sound and video signals to the home network controller 280. The home network controller 280 converts and compresses the audio and video signals into video data in the form of MPEG TS packets through the encoder 310 and transmits the compressed data to the ubiquitous management server 270 (S514). In this case, the home network controller 280 may generate a content in which a playback program, a resource, user addition data, and a management program are added to the video data of the audio and video signal, and transmit the content to the ubiquitous management server 270.

The ubiquitous management server 270 hybridly moves video data received from the home network controller 280 through the IP network 260, the PDSN 250, the EV-DO controller 234, and the EV-DO transmitter 224. Control to be transmitted to the terminal 210 (S516).
At this time, when the ubiquitous management server 270 receives the video data from the home network control device 280, the ubiquitous management server 270 generates and stores the content in which the playback program, the resource, the user addition data, and the management program are added to the video data, or the hybrid mobile terminal ( 210).

The hybrid mobile terminal 210 displays the received video data on the LCD screen, and the subscriber can check the situation of the living room in his home through the displayed video.
Herein, if the hybrid mobile terminal 210 is a content in which media data, a playback program, a resource, user addition data, and a management program are added to the received video data, the hybrid mobile terminal 210 may play the video data using a playback program included in the content. The user's description may be arbitrarily added to the user addition data.

On the other hand, when the subscriber accesses the ubiquitous management server 270 and sets the ubiquitous for the "home video", the living room does not provide a real-time situation for the corresponding place in the home, for example, every one hour for one minute every five hours If set to, the ubiquitous management server 270 is counting the time, for example, if the set time, for example, if the time set by the subscriber is 9:00 am, 5 hours have elapsed at 2 pm video to the home network controller 280 After the request data is transmitted, the video data of the living room is received from the home network controller 280 and stored in the storage space of the ubiquitous database 272 allocated to the subscriber.

Therefore, after 2 pm, the subscriber accesses the ubiquitous management server 270 through the hybrid mobile terminal 210 to request a video for the living room of the home, and the ubiquitous management server 270 is the ubiquitous database 272. Read the video data for the living room from the hybrid mobile terminal 210 and transmits through the EV-DO system as described above.

Of course, the subscriber may access the ubiquitous management server 270 to select a place for requesting a video and a time zone in which the video is to be provided, and the ubiquitous management server 270 may be a place set by the subscriber, for example, a "room." After storing the video for, and querying whether or not to transmit and receive a message indicating that there is a home video requested to the hybrid mobile terminal 210 at a time set by the subscriber, for example, 5 pm, When the reception is allowed, the video data of the corresponding "home" may be transmitted to the hybrid mobile terminal 210.
As described above, in the present invention, a home network device generates a content captured by each camera as a content and provides the content to a user terminal, or a home network device delivers the captured image to a ubiquitous server, thereby generating a content by the ubiquitous server. You can give it to the terminal.

As described above, according to the embodiment of the present invention, a small camera is installed in a place where surveillance is required in a house, a building, a specific place, or the like, connected to a communication network, and a small camera is controlled by using a user terminal from an external or remote location. It is possible to realize a ubiquitous control method and system for receiving and displaying a video taken in real time or a video shot at a predetermined time as a functional content.
