The present invention relates to a home network device, and more particularly, to a home network connection device from a remote location and a control method thereof.

With the development of digital technology, digital home appliances (DTV, STB, DVD, DVHS, DVC, etc.) have appeared on the market, and the method of connecting digital products is naturally enacted as a standard.

Among them, HAVi (Home Audio Video interoperability) is one of the standards for configuring a home network by connecting home appliances complying with the 1394 interface standard.

HAVi is a middleware that allows home appliances and PCs in a home to interoperate with each other based on IEEE 1394 and IEC61883 standards.

The conceptual protocol stack of HAVi is shown in FIG.

That is, a HAVi-compliant device generally has a software structure as shown in FIG. 1, and the HAVi standard defines software modules between an interoperability API and a platform specific API.

In Figure 1, FCM (Functional Component Module) is a part that provides an API for controlling the function of the device, HAVi according to the type of home appliances Tuner FCM, VCR FCM, Clock FCM, Camera FCM, AV Disc FCM, Amplifier FCM , Display FCM, AV DisplayFCM, Modem FCM and Web Proxy FCM are defined.

The Messaging System serves as an information input / output path between the Event Manager, the Registry, the Stream Manager, the Resource Manager, and the DCM Manager. The 1394 Communication Media Manager is a bus reset of each home appliance connected to the 1394 line, that is, the connection of the home appliance, It detects separation and provides such event information to the Event Manager.

In the above, the Registry is a part for providing information on which FCM (Functional Component Module) is operating, the Resource Manager is a part for adjusting when a specific function conflict occurs, and the DCM Manager is for This part performs the function to turn on and off.

However, in the prior art, the connection between the HAVi home network and the external web server is connected to the HAVi home network based on the IEEE 1394 interface standard between the web client 210 and the gateway system 220 as shown in the configuration of FIG. The gateway system 220 and the web server 230 are connected to the Internet.

The web client 210 is a home appliance having an arbitrary function. The web client 210 includes an Internet application protocol such as the HTTP 211 and communicates with the web gateway system 220. And a messaging system 212.

The gateway system 220 is a part that is connected between the web client 210 and the web server 230 to serve as a web gateway for providing an internet protocol. The hardware and internet protocol stack capable of internet access in a HAVi home network is provided. Provided by any household appliance having a.

That is, the gateway system 220 is a home appliance having any function in which the web proxy FCM 221 exists. The gateway system 220 communicates with the web client 210 using the messaging system 222 and is based on TCP / IP. Communication with the web server 230 by using the Internet communication device 223 of the communication system, and between the messaging system 222 and the Internet communication device 223 by using the Web Proxy FCM 221. Will be connected.

The web proxy FCM 221 provides the following API to enable the web client 210 to access the Internet.

WebProxy :: Open ()

WebProxy :: Close ()

WebProxy :: Send ()

<Client> :: Receive ()

WebProxy :: GetCapability ()

First, the web client 210 uses the WebProxy :: Open () API of the web proxy FCM 221 which determines which home appliance the web proxy FCM 221 is located through the registry (eg, In addition to opening http), you will be informed of the size of the message that can be received at a time.

At this time, the web proxy FCM 221 is used as an HTTP agent (agent) and allocates a cid (connection id) to the web client 210 and informs the message size to be transmitted at a time.

Thereafter, when the connection is established, the web client 210 sends an http request signal to the web proxy FCM 221 through the WebProxy :: Send () API.

In this case, when the web proxy FCM 221 receives a request signal from the web client 210, the web proxy FCM 221 connects to the web server 230 through TCP and transmits a request signal to the web server 230.

Thereafter, when a response signal is transmitted from the web server 230, the web proxy FCM 221 transmits the content to the web client 210 through the <Client> :: Receive () API.

Thereafter, when the web client 210 wants to disconnect, the web client 210 is achieved by calling the WebProxy :: Close () API to the web proxy FCM 221.

That is, in the HAVi home network, the web client 210 provides a method for accessing the Internet through the web proxy FCM 221.

However, at present, HAVi does not define a protocol for controlling home appliances connected to the HAVi home network in the home using the Internet from an external remote location.

Therefore, there is currently no way to control home appliances connected to the HAVi home network in the home using the Internet from an external remote location.

Therefore, in order to solve the above problems, the present invention registers home appliances connected to HAVi home networks in homes as respective web servers, and accesses home networks from remote sites created to control the home appliances from external remote sites. It is an object to provide an apparatus and a control method thereof.

Hereinafter, the present invention will be described in detail with reference to the drawings.

In the present invention, each home appliance (for example, DVCR, DVD, etc.) connected to the HAVi home network operates as a web server providing an HTML file recording a control method. There is a Web Server Proxy Agent.

That is, in the embodiment of the present invention, the connection between the HAVi home network and the external web client is as shown in the configuration of FIG. 4, and the web server 410 and the gateway system 420 are connected to the HAVi home network based on the IEEE 1394 interface standard. The gateway system 420 and the web client 430 are connected to the Internet.

First, the web server FCM 411 provided in the web server 410 defines an API as follows to provide an HTML file recording a control flow.

StatusWebServer :: GetHTMLFile (

in sequence <octet> link

out sequence <octet> html)

Here, the input parameter 'link' is an HTML file to be provided, and the output parameter 'html' is an HTML file corresponding to the 'link'.

In addition, the web server proxy agent 421 included in the gateway system 420 processes the request signal of the web client 430 transmitted from the Internet.

It handles tasks such as dynamic home page editing, link information provision, web server daemon, etc.

The dynamic homepage editing function is to identify a device capable of operating as a web server among home appliances connected to the HAVi home network and to produce a homepage (1st page view).

That is, since the HAVi home network connected with the 1394 cable can dynamically plug-in / out devices connected to the network, the web server proxy agent 421 changes the home page content every time.

The link information providing function sets a device with a web server proxy agent as a root directory and a device with a web server FCM as a child directory among the home appliances connected to the HAVi home network. Report the pass information of the link.

In other words, the HAVi home network is a distributed file system in which HTML files are distributed to various devices in the network, so such link information is required.

Here, the name of the child directory is set to the GUID (Grobal Unique ID) of the device.

The web server daemon function is for receiving a request signal from the Internet and providing an HTML file for control information of the corresponding device.

Therefore, the operation of the embodiment of the present invention based on the above concept will be described with reference to a web server FCM and a web server proxy agent.

First, the HAVi protocol-based web server 410 is a home appliance having any function. When the power is turned on, the web server FCM 411 provided in the device uses the MsgOpen () API of the messaging system 412. The SEID is allocated from the web server proxy agent 421 included in the gateway system 420, and the Software Element (SE) Type Attribute is registered as 'WEBSERVER_FCM' in the 'Registry'.

In addition, the gateway system 420 having a web server proxy agent is a home appliance having any function, and the home appliance that is powered on or connected to the HAVi home network is plug-in / out. If a network reset occurs, the following functions are performed.

The web server proxy agent 421 included in the gateway system 420 determines whether there is an FCM in which the SE type attribute is registered as 'WEBSERVER_FCM' in 'Registry'.

If a new FCM is found in comparison to the existing database (DB), that is, when the web server 410 having the web server FCM 211 is plugins in the network, the web server proxy agent 421 may be connected to the database DB. Add the SEID of the FCM.

After that, since a new web server FCM has entered, the web server proxy agent 421 updates the home page in the following manner.

-Perform DCM :: GetDeviceIcon () to get the image file from the plugged-in device.

-Assign 'link' information to the image file as '.. \ guid \ index.html'.

On the contrary, if the FCM exits from the existing database (DB), that is, if any device is Plug_Out from the home network, the web server proxy agent 421 deletes it from the database and removes 'Link' from the home page. do.

When the above process is performed, a home page containing information of web servers currently connected to the HAVi home network is created.

That is, the first homepage (html view) provided from the gateway system 420 to the web client 430 when the request signal comes from the Internet through an IP address or URL of the home network is illustrated in FIG. 5.

At this time, when the user accesses the home HAVi network from the remote web client 430 by using the Internet, the gateway system 420 provides the web server proxy agent 421 with a home page as shown in FIG. 5.

Accordingly, the web client 430 selects the icon of the device to be controlled from the icon Icon having 'Link' information illustrated in the home page of FIG. 5.

At this time, the web server proxy agent 421 provided in the gateway system 420 uses the WebServer :: GetHTMLFile (link, html) API of the web server FCM 411 to perform an index 'index.' html '

In the 'index.html' control information of the corresponding device (Control Information) is recorded in the HTML format, for example, in the case of index.html of the DVCR as shown in the example of FIG.

If the user selects 'PLAY Link' from the homepage of FIG. 6, the web server FCM 411 inputs 'play.html' input through the WebServer :: GetHTMLFile (link, html) API to the web server proxy agent 421. If received from the device performs a PLAY function and transmits the response html file 'play.html' to the web server proxy agent 421 as an output.

If the user wants to perform the stop operation during the playback operation, the remote web client 430 stops the DVCR playback by selecting the 'STOP Link' displayed in the 'index.html' of the DVCR.

In the embodiment of the present invention has been described for the operation of a single web server, according to which home appliances are connected to the home network to create a home page as shown in Figure 5 can control the function of the desired home appliances have.

In other words, the present invention manages HTML files existing in various devices in the HAVi home network through a Web Server Proxy Agent, and dynamically updates the first home page whenever a network reset occurs. And HAVi network.

In addition, in the present invention, each device connected to a home network may be controlled from a PC or an Internet access device at a remote location by processing a request signal from the Internet and sending a response signal through a web server FCM.

As described in detail above, the present invention proposes a model for a Web Server FCM and a Web Server Proxy Agent to connect to a HAVi home network using the Internet. There is an effect that requests can be processed in the HAVi home network.

In particular, the present invention is to share the resources (Internet Application Protocol, TCP, IP, Hardware, etc.) of the web-accessible devices to each home appliance connected to the HAVi home network, so that other devices from the Internet even if only HTML file There is an effect that can process the request signal.

In addition, in the present invention, the link information of the html file is distributed for each device connected to the HAVi home network, but since the corresponding device can be determined using the 'GUID', it is easy to control the corresponding device from a remote location. There is.
