Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a home network system according to an embodiment of the present invention.

Referring to FIG. 1, a home network system according to the present invention includes a plurality of home devices 105 and a home gateway server 110 coupled with a home device 105 through a communication means.

The indoor device 105 may be a multimedia device (eg, a web camera, a personal video recorder (PVR), a digital video recorder (DVR), a digital radio recorder and a player, etc.), a white appliance (eg, a refrigerator, a washing machine, etc.). It may include all electrical and electronic devices provided in the home, such as electric lights and heating appliances. However, hereinafter, for convenience of explanation, it is assumed that the indoor device 105 is a multimedia device such as a web camera 105a, a PVR 105b, a DVR 105c, a digital radio recorder, and a player 105d. .

The home gateway server 110 may include an interface unit 115, an IP address manager 120, a storage area manager 125, a memory 130, a communication port manager 135, a transceiver 140, and an authentication processor 145. ), A UI manager 150, and a controller 155.

The interface unit 115 is a means for allowing the indoor devices 105 and the home gateway server 110 to be coupled through a communication network. The home gateway server 110 and the indoor devices 105 may be combined through a local area network (LAN) or a local area network (eg, IrDA, Bluetooth, etc.), and may be interfaced according to the type of communication network. The unit 115 may be configured in various ways.

The IP address management unit 120 according to the request for the allocation of the internal IP address received from the indoor device 105 in the process of booting any of the indoor devices 105 coupled through the interface unit 115 Is assigned to the indoor device 105, the server internal IP address assigned to the home gateway server 110 (this is the home device 105 and the home gateway server 110 in the home network to transmit and receive data Internal IP address assigned to gateway server 110, which may be assigned to, for example, 192.168.1.1), and broadcast to the combined indoor devices 105. As described above, the home gateway server 110 according to the present invention has both a public IP address for connecting to an external communication network and an internal server IP for interworking with the indoor device 105 on the home network. Here, the internal IP address and the server internal IP address are IP addresses (for example, 192.168.1.2) to be used only inside the home network, unlike public IP addresses (for example, 211.100.100.20), and may be dynamic IP addresses. Can be. The IP address manager 120 may use a standard Dynamic Host Configuration Protocol (DHCP) scheme in allocating an internal IP address to any indoor device 105. Since a method of allocating an internal IP address to an arbitrary communication device using a DHCP method is obvious to those skilled in the art, a description thereof will be omitted.

The storage area manager 125 is configured to generate data generated by each indoor device 105 coupled through the interface unit 115 (for example, video data corresponding to an image input through the web camera 105a). A certain area of the memory unit 130 is allocated to a dedicated storage area corresponding to each indoor device 105 so that the multimedia data corresponding to the device may be stored in a corresponding dedicated storage area. The storage area manager 125 determines whether a dedicated storage area corresponding to each of the indoor devices 105 has already been allocated to a predetermined area of the memory 130, and includes the name of the device, the code number of the device, and the Ethernet hardware address (MAC) of the device. It can be determined using unique information such as Address). In addition, a dedicated storage area corresponding to each indoor device 105 may be divided by a directory name or a folder name, and the name may be automatically assigned to correspond to unique information of the indoor device 105.

The memory unit 130 is a means for storing the operation program of the home gateway server 110 and the multimedia data generated by each indoor device 105 in a dedicated storage area corresponding to each indoor device 105. When the storage area management unit 125 generates a dedicated storage area for an arbitrary indoor device 105 (for example, creates a folder), the memory unit 130 functions as a network drive of the indoor device 105. Done. This will be described later in detail with reference to FIG. 2.

When the communication port management unit 135 receives the communication port information to be used from any indoor device 105, the communication port manager 135 determines whether the corresponding communication port is already used by another indoor device 105 and selects an appropriate communication port. (105) to manage. This is to solve the problem that it is impossible to directly access each indoor device 105 from the outside when a plurality of internal IP addresses are used under one public IP address. A method of setting an appropriate communication port corresponding to each indoor device 105 will be described in detail later with reference to FIG. 3.

Transmitting and receiving unit 140 is a user terminal (170a, 170b, ..., 170n-hereinafter referred to as 170) coupled via an external communication network, such as the Internet and information (for example, a function selection signal, any home appliance 105 Means for transmitting and receiving multimedia data). The user terminal 170 may use a home network access program that is pre-installed to access the home gateway server 110, or a web server access method through a general Internet. The transceiver 140 may include, for example, a wide area network (WAN) port, a modem, or the like.

When an access request is received from any user terminal 170 through an external communication network, the authentication processing unit 145 performs authentication to determine whether the user terminal 170 is a legitimate user terminal. The authentication may be performed by using identification information such as telephone number information received from the user terminal 170 or through a login process including an ID and a password. Of course, the authentication function may be individually performed by the corresponding indoor device 105 directly connected to the user terminal 170 through port forwarding, in which case the authentication processing unit 145 may be omitted.

The UI manager 150 generates and manages a UI (User Interface) display screen to be transmitted to the user terminal 170 after the user authentication by the authentication processor 145 is completed. The UI display screen may include a list of indoor devices 105 coupled with the home gateway server 110, and if any indoor device 105 is selected, control of the indoor device 105 or reproduction of generated multimedia data. A new UI display screen for transmitting to the user terminal 170 may be transmitted.

The control unit 155 provides a dedicated storage area corresponding to the home devices 105 coupled to the home gateway server 110 according to the present invention through the interface unit 115, integrated management of multimedia data, and access through an external communication network. Interface unit 115, IP address management unit 120, storage area management unit 125, memory unit 130, and the like to perform remote control of a home device and remote use of multimedia data by the user terminal 170. The communication port manager 135, the transceiver 140, the authentication processor 145, and the UI manager 150 are controlled.

2 is a diagram illustrating a network drive setting process of an indoor device according to an exemplary embodiment of the present invention.

Referring to FIG. 2, in step 210, the indoor device 105 starts a booting procedure. The booting procedure may be a preparation process for preparing to operate the indoor device when the indoor device is powered on.

In operation 215, the indoor device 105 transmits an internal IP address allocation request to the combined home gateway server 110 through the communication network during the booting procedure of operation 210.

In step 220, the home gateway server 110 is an internal IP address that may be assigned to the indoor device 105 by a standard DHCP (RFC 2131) method, or the like, and is not used by another indoor device 105. Extract the address. The home gateway server 110 transmits the internal IP address extracted in step 225 to the indoor device 105 which has transmitted the internal IP address allocation request in step 215. In step 220 or step 225, the home gateway server 110 may store and manage information about which indoor device 105 the currently extracted internal IP address corresponds to.

In operation 230, the indoor device 105 sets its network information using the internal IP address received from the home gateway server 110.

Thereafter, the indoor device 105 requests the server internal IP address (that is, the internal IP address assigned to the home gateway server) from the home gateway server 110 in step 235, and the server from the home gateway server 110 in step 240. Receive an internal IP address. At this time, the request and / or reception of the server internal IP address may be performed through a broadcasting (broadcasting) method, when the request for the server internal IP address, the indoor device 105 checks the set internal IP address, etc. The corresponding information may be transmitted to the home gateway server 110 to achieve the purpose.

In operation 245, the indoor device 105 transmits a confirmation request to the home gateway server 110 to determine whether there is a dedicated storage area (ie, a dedicated folder or a dedicated directory) created to correspond to the home gateway server 110. The confirmation request may include unique information such as a name of the device, a code number of the device, an Ethernet hardware address of the device, and the like.

The home gateway server 110 determines whether there is a dedicated storage area corresponding to the unique information received from the indoor device 105 in step 250. For example, when the name of the dedicated storage area matches the unique information, the home gateway server 110 may search for whether a folder name or a directory name matching the unique information exists. .

If the dedicated storage area corresponding to the indoor device 105 already exists, the home gateway server 110 proceeds to step 265 and transmits the dedicated folder existence response to the indoor device 105.

However, if there is no dedicated storage area corresponding to the indoor device 105, the home gateway server 110 uses the unique information corresponding to the indoor device 105 in step 260 to dedicate the corresponding private device 105. A storage area is generated (that is, a predetermined storage area of the storage area of the memory unit 130 is allocated as a dedicated storage area). Thereafter, the home gateway server 110 transmits a dedicated folder creation response to the indoor device 105 in step 265. The dedicated folder creation response may include information regarding what name of folder or directory is assigned to the dedicated storage area.

In operation 270, the indoor device 105 may use a dedicated storage area allocated in the memory unit 130 as a disk driver built in the indoor device 105 by mounting the network driver or NFS (Network File System). To be set. In operation 270, the indoor device 105 may record the multimedia data in the dedicated storage area or play the multimedia data stored in the dedicated storage area through a communication network.

As such, the home gateway server 110 according to the present invention may allocate a dedicated storage area to each of a plurality of premises devices coupled through a communication network, and each premises device 105 is generated even if it does not have a separate storage unit. One multimedia data can be stored in a dedicated storage area. In addition, when the home gateway server 110 allocates a dedicated storage area corresponding to each indoor device, each indoor device 105 accesses the home gateway server 110 to access a dedicated storage area of another indoor device. The multimedia data generated by another indoor device may be reproduced (for example, the multimedia data generated by a web camera may be reproduced on a digital television). Of course, the indoor device 105 is set by the internal IP address received from the home gateway server 110 coupled with the home gateway server 110 via a communication network, and within the dedicated storage area allocated within the home gateway server 110. It should be capable of recording multimedia data and having a function capable of performing a function corresponding to the selection information received in combination with the remote user terminal 170. However, since a method for embedding a program having a communication interface in the indoor device 105 and implementing the above-described operation will be easily understood by those skilled in the art through the specification of the present invention, a description thereof will be omitted.

In addition, the above drawings are for explaining the case where the internal IP address corresponding to each of the indoor devices 105 is performed by the home gateway server 110 is performed. Obviously, if the indoor devices 105 each have a unique public IP address, steps 215 to 230 may be omitted. In addition, since the home gateway server 110 also uses a public IP address, in this case, the internal server IP address of steps 235 and 240 should be changed to a public IP address corresponding to the home gateway server 110.

2 is assuming that the home gateway server 110 is operating normally before the home devices 105 are turned on. However, in some cases, the home gateway server 110 may switch from the power off state to the power on state after the home appliance 105 is powered on. In this case, unlike the steps of FIG. 2 described above, the home gateway server 110 determines whether there is an indoor device that already exists in a power-on state among the indoor devices coupled through the home network, and then the corresponding home device exists. If it is determined that the internal IP address setting for the indoor device has been made, if the internal IP address setting is not made it is obvious that the process can proceed from step 220. Of course, the steps of FIG. 2 may be applied to the indoor device 105 that is powered on after the home gateway server 110 is powered on.

3 illustrates a method of generating a port forwarding table according to an embodiment of the present invention.

Port forwarding refers to a technology that automatically connects to a web connection even if a port number is not attached to a port other than the default port 80. In general, each communication device has a communication port that it uses. However, when using a plurality of internal IP addresses together with one public IP address, it is impossible to directly connect to any communication device from the outside. Therefore, the home gateway server 110 according to the present invention should forward communication ports used by each communication device to solve this problem. Hereinafter, a method of generating a port forwarding table by the home gateway server 110 according to the present invention will be described with reference to FIG. 3. In addition, the following port forwarding generation process may be performed during or after the network drive setting process described with reference to FIG. 3 (for example, immediately after allocating an internal IP address to the indoor device 105).

Referring to FIG. 3, in step 310, the indoor device 105 transmits port information to be used by the home gateway server 110.

In step 315, the home gateway server 110 determines whether the communication port is already registered (that is, the communication port preempted by another indoor device).

If the communication port is already registered, the home gateway server 110 transmits another port use request to the indoor device 105 in step 320. In operation 325, other communication port information to be used is received from the indoor device 105. The home gateway server 110 may proceed to step 315 again when other communication port information to be used is received from the indoor device 105.

However, if the port information received from the indoor device 105 does not correspond to a communication port already registered, the home gateway server 110 adds the port information to the port forwarding table to correspond to the indoor device 105 at step 330. Register. Through the above-described process, the port information of the indoor device 105 is registered in the port forwarding table, so that the user can access the indoor device 105 remotely using the user terminal 170.

As described above, the home appliance 105 receives an internal IP address from the home gateway server 110 and then displays the device's characteristics (eg, function, unique information, etc.) and / or the internal IP address of the home gateway server. Transmit to 110. As a result, the home gateway server 110 may store and manage the type, feature, internal IP address, port information, and the like of the indoor device in the memory unit 130. In addition, the port forwarding table generated through the above-described process may be managed by the communication port manager 135.

4 is a diagram illustrating a method for accessing an indoor device at a remote location according to an exemplary embodiment of the present invention, and FIG. 5 is a diagram illustrating a network connection process according to an exemplary embodiment of the present invention.

The home gateway server 110 according to the present invention dynamically assigns an internal IP address and a communication port for the indoor device 105, so that the user can access any indoor device 105 remotely. This is needed.

4, in step 410, the home gateway server 110 receives a server connection request from the user terminal 170. In this case, the user may access the home gateway server 110 using a home network access program (that is, an indoor device control program) installed in the user terminal 170. A method of implementing a program for accessing the home gateway server 110 to receive and display the indoor device 105 information from the home gateway server 110 and performing the following process can be easily understood by those skilled in the art through the specification of the present invention. Since it will be able to be described, the description thereof will be omitted. Of course, according to the system implementation method, the user may access the home gateway server 110 using the Internet access function provided in the user terminal 170.

The home gateway server 110 generates a list of indoor devices coupled to the home gateway server 110 through a communication network in step 415, and transmits a list of indoor devices to the user terminal 170 in step 420. In the list of indoor devices, names of indoor devices, IP and communication port information for each device (for example, PVR is "http://www.homenetwork.net:9000/" and DVR is "http: //www.homenetwork. net: 9001 / ", etc.). In this case, when the user terminal 170 is provided with a preset home network connection program, only necessary data (for example, device name, IP and communication port information of each device, etc.) needs to be extracted and transmitted. If the home gateway server 110 accesses the home gateway server 110 using a web browser program, the home gateway server 110 should generate a web page including the corresponding information and transmit the web page to the user terminal 170. The home gateway server 110 can easily determine whether the user is connected by using a home network access program or a web browser program, and generates a list of indoor devices corresponding to the user terminal 170. Can be sent to.

In operation 425, the user terminal 170 determines whether selection information regarding any indoor device in the list of indoor devices displayed by the user on the display unit is input.

When the indoor device selection information is input, the user terminal 170 transmits the indoor device connection request to the home gateway server 110 in step 430. The home gateway server 110 generates a visually recognizable function and / or data selection screen to correspond to the indoor device selection information received in step 430 (step 435) and transmits it to the user terminal 170 (step 440). . In this case, as described above, it is obvious that the configuration of the function selection screen may vary depending on the program used by the user. In the function and / or data selection screen, a function that can be executed by the indoor device (for example, in the case of a web camera, power-up, power-off, recording, zoom-in, and lens angle) Control, etc.), and a list of multimedia data stored in a dedicated storage area corresponding to the indoor device. Of course, in step 430, the home gateway server 110 may be directly connected to the indoor device using the port forwarding technique when the arbitrary device selection information is received from the user terminal 170 (see Fig. 5). In this case, a function and / or data selection screen corresponding to the indoor device selection information may be generated by the indoor device and transmitted to the user terminal 170.

In operation 445, the user terminal 170 selects an arbitrary function (eg, selects a specific function) or an arbitrary data selection (eg, specific multimedia data) from among the functions and / or data selection screens displayed on the display by the user. Is selected).

If any function selection is input by the user, the user terminal 170 transmits a function execution request (eg, a recording function execution request) corresponding to the function selection to the home gateway server 110 in step 450. Thereafter, the home gateway server 110 allows a function corresponding to the function execution request to be performed by the corresponding indoor device 105. For example, if the function execution request is a recording function execution request, the home gateway server 110 transmits the received function execution request to the indoor device 105 to generate an image input through the lens as multimedia data. At this time, the home gateway server 110 may convert the function execution request received from the user terminal 170 into a control signal that the indoor device 105 may recognize and execute. Of course, when the function execution request is directly transmitted from the user terminal 170 to the indoor device 105 by the port forwarding technology, the indoor device 105 converts the function performance request into an appropriate control signal. This function can be performed.

In addition, when an arbitrary data selection is input by the user, the user terminal 170 transmits the data selection information to the home gateway server 110 in step 450. Of course, the data selection information may be transmitted directly to the corresponding indoor device 105 by port forwarding. Thereafter, the home gateway server 110 (or the indoor device 105 connected by port forwarding) transmits a query on how to use the selected data (for example, downloading or playing multimedia data) to the user terminal 170. Thereafter, corresponding data processing is performed in response to the response received from the user terminal 170. As the method of performing data processing in the home gateway server 110 or the indoor device 105, the following three methods may be applied. First, the home appliance 105 extracts data corresponding to the data selection information from the dedicated storage area and transmits the data to the user terminal 170 via the home gateway server 110. Second, when the indoor device 105 transmits a data transmission request corresponding to the data selection information to the home gateway server 105, the home gateway server 105 extracts the corresponding data and transmits the data to the user terminal 170. It is. Third, even though the user terminal 170 is directly connected to the indoor device 105 by port forwarding, since the data selection information is transmitted to the indoor device 105 via the home gateway server 110, the home gateway server 110 ) May recognize whether the data selection information is received, and when the data selection information is received, a method of directly extracting the corresponding data from the storage unit and transmitting the corresponding data to the user terminal 170.

Of course, when the user transmits arbitrary data selection information, it is obvious that the user can automatically play (eg, a streaming method, a download after playing, etc.) through a plug-in program included in the home network access program. In this case, when the user accesses an arbitrary indoor device 105, the user does not have to use only multimedia data in a dedicated storage area corresponding to the indoor device 105, but uses another switching device such as a folder moving function. Multimedia data in a dedicated storage area corresponding to 105 may also be used.

As described above, the method for allocating the generated data storage space using the home network according to the present invention and the home gateway server share data that any indoor device can be generated or reproduced by another indoor device (data compatibility function between the indoor devices). can do.

In addition, the present invention allows data generated by each of a plurality of indoor devices to be stored in a dedicated storage area for each indoor device in a storage unit of a home gateway device coupled through a communication means, thereby enabling integrated management of data.

In addition, the present invention does not need to include a separate memory even when a user wants to store and manage data generated by each indoor device.

In addition, the present invention enables the user to control the setting of the indoor device at a remote location and use data (for example, download, playback, etc.) by using a terminal that can be connected to a communication network.
