The present invention relates to a structure of home audio / video interoperability (HAVI), and more particularly, to a method for controlling a device in a home network environment.

A home network system is a system that literally connects and controls PCs, peripherals, mobile phones, and home appliances at home.

In other words, it is possible to control all digital home appliances such as computers, digital televisions, digital video players, and air conditioners by accessing a network built in a home through the Internet or a telephone line both internally and externally.

Such a home network is currently under development in accordance with IEEE1394 and IEC61883 standards to control all devices in a home through a single device.

At this time, in order to control all the devices in the home as a single device, a protocol for integrating and controlling various signals on the IEEE1394 should be provided and show the current progress by showing the movement of each device to the user. Only then can the home network be realized.

In other words, it provides a user with an environment where simple connection and easy operation (hot plug & play) can be performed, and through a GUI (Graphic User Interface), the contents (content), not access to the device. It must provide operability as if accessed by itself.

To do this, first, standardized middleware that manages resources on the network is required, and future compatibility must also be considered.

One example is the HAVI (Home Audio / Video Interoperability) structure that controls each device by configuring an operation scenario through a GUI (Graphic User Interface) between the devices.

The HAVI structure was proposed by 8 AV manufacturers, and 15 companies recently expressed support.

This HAVI structure is based on the IEEE1394 and IEC61883 standards, and consumer electronics products (DTV, DSTB, DVD, DVHS, DVC) and PC are composed of home networks to ensure interoperability. The consumer electronic industry standard consists of several software modules and their application programming interfaces (APIs).

HAVI includes four big features:                         

First, by providing a general API (Application Programming Interface) to the AV network, it allows the application software (application software) can be built without worrying about the lower layer (layer).

The second function is to manage resources on the network and to perform coordination between controllers.

Third, the controller does not require knowledge of an external device and can be controlled by an upload function of a device driver called a device control module (DCM).

Fourth, it provides a GUI called DDI (Data Driven Interaction) protocol.

As the HAVI structure is extended to digital devices (DTV, STB, DVCR, Dcamera ...) in the future, when controlling through GUI between devices, there is a need to distinguish each device.

The distinction between the devices is distinguished as 64-bit unique data called a GUID (Global Unique ID), but this is not a familiar expression for the general user.

Accordingly, in the HAVI specification, a field called HAVI_User_Preferred_Name is prepared in an IEEE1212 configuration ROM called SDD (Self Describing Device) data to enable a user to read / write a desired name.                         

Therefore, there is a need for a method of easily inputting any device name desired by the user and recognizing the HAVI device.

On the other hand, in the HAVI structure, control of each device is performed using a software element called a device control module (DCM).

DCM is obtained by installing a DCM code unit, which consists of code for DCM, code for Functional Component Modules (FCM), and an associated profile.

That is, when the user uses the function of each device, the application software performs control using the API of DCM or FCM.

For example, if the user changes to the channel remote control of the DTV, the application software changes the channel using the Tuner :: SelectService API of the tuner FCM.

Therefore, in order to control each device by the HAVI specification, a DCM representing each device must exist.

DCM is divided into pre-installed embedded DCM and JAVA uploaded DCM in the device.

Meanwhile, in the HAVI specification, each device is classified into the following four classes.

It is classified into FAV (Full AV Device), IAV (Intermediate AV Device), BAV (Base AV Device), and LAV (Legacy AV Device).

The FAV (Full AV Device) is a controller capable of Java execution environment, the IAV (Intermediate AV Device) is a controller capable of executing only embedded DCM, and the BAV (Base AV Device) holds only HAVI SDD data and HAVI structure software. The element is a controller without, and the LAV (Legacy AV Device) is a non-HAVI-compliant device.

To control by the HAVI specification in the environment as shown in FIG. 1, the DCM (ie, DCM DVCR) of the LAV 20 must be installed in the FAV 10.

DCM Manager (DCMM) 11 in FAV is responsible for uploading and installing DCM in java byte code unit format from the specified URL if DCM in LAV is uploaded DCM. do.

Thus, the structure of the HAVI structure software element in the FAV 10 is as shown in FIG.

Referring to FIG. 2, a 1394 device drive 300 for connecting devices in a home with a digital interface and a HAVI software module 200 for processing an event through message communication between devices transmitted through the 1394 device drive 300 are described. And an external application unit 100 for controlling the HAVI software module with an external control signal.

The HAVI software module 200 is divided into a system software module 220 and a non system software module 210.

The system software module 220 includes a 1394 Communication Media Manager 227 for controlling asynchronous and isochronous conversations, a messaging system 226 for performing message transfer between elements, An event manager 221 performing an event delivery function such as a state transition of a home network object, a stream manager 223 providing a real time transmission management function of AV and other media between functional elements, and Install a registry 222 that allows one object to place another object on the home network, a resource manager 224 that manages resources, and DCM code in FAV and IAV devices. Or DCM manager 225 to remove or remove.

The non-system software module 210 is a device element (DCM) 213 which is a software element used to control a device, and a DDI which is a byte code object included in a user interaction. The controller 211 includes a Java virtual device 212, a Functional Component Nodules (FCM) 214, and a Device Control Application (DCA) 215.

The URL location of the LAV DCM to upload can be a predefined location, but it can also be the user's preferred location.

Therefore, in the HAVI specification, a field called DCM_Preferred_URL is prepared in the DCM manager so that the user can read / write a desired position.

Therefore, there is a need for a method of easily inputting an arbitrary location desired by a user and recognizing the HAVI device.

Accordingly, the present invention provides a virtual keyboard in a home network composed of digital devices employing the HAVI structure, more easily input the name of the connected device to an arbitrary location desired by the user, and recognizes each connection to the HAVI device. The purpose is to facilitate easy differentiation between devices.

Another object of the present invention is to provide a user-friendly environment by allowing a user to directly input a URL location for a LAV DCM so that the latest DCM can be used.

In order to achieve the above object, there is provided a method of setting a name of a connected device of a home network system according to the present invention. The first display step of displaying a HAVI home mode on a device having a display means through an external HAVI conversion input; After selecting the connected device to be changed through the displayed HAVI home mode, the second display step of displaying a virtual keyboard on the screen, and using the displayed virtual keyboard, select the desired spelling, number, or alphabet to connect the connected device. And setting a name of the, a HAVI_User_Preferred_Name of the SDD using the set name, and displaying a HAVI home mode on the device having the display means by using the changed name. To lose.

According to an aspect of the present invention, a virtual keyboard is provided in the HAVI structure, so that a user can directly input a name of a desired connection device, and the user can freely set the name of the connection device.

Other objects, features and advantages of the present invention will become apparent from the following detailed description of embodiments taken in conjunction with the accompanying drawings.

Referring to the accompanying drawings, a preferred embodiment of a method for setting a name of a connected device in a home network system according to the present invention will be described below.

6 is a flowchart illustrating a method of setting a name of a connected device in a home network system according to the present invention.

Referring to FIG. 6, it is assumed that a user sets a name of another device (for example, a PC) around a DTV, and will be described by comparing FIG. 3 and FIG.

First, when the power-on of the DTV having a display means or the like (non-HAVI) mode state (S10).

Subsequently, the HAVI mode is selected through a remote controller or other external input device (S20).

Then, the application software in the DTV uses the CMM1394 :: GetGUIDList command to determine the GUID (Global Unique IDentifier) of the device currently connected on the same network, that is, the home appliance, and the SDD data of the device using the CMM1394: AsyncRead command. Read (S30).

Then, the manufacturer's name, model name and model icon are displayed on the DTV screen using the read SDD data (S40).

The displayed screen at this time is shown in FIG.

That is, the DTV is converted to the HAVI mode as shown in FIG.

In this case, when the user wants to set the device name to an easy-to-identify name, a typical home appliance such as a DTV mainly uses a remote controller as a command input means, and a keyboard is not provided.                     

Therefore, when the user wants to set the HAVI device to the name or URL location desired by the user, there is no proper input means.

Accordingly, in the present invention, a virtual keyboard is presented to a user, and the user inputs a desired name or URL location, so that the device can be distinguished later and the LAV DCM can be updated.

Looking at the method, first, select the "name setting function" using the remote control 30 or an external input device in step 1 (S50), and select the URL location setting function (S60).

In the next two steps, the "device to be set" is selected (S70).

In this case, the device to be set can be distinguished since the icon can be displayed as shown in FIG.

Regardless of the type of each device, step 2 may be omitted if URL location setting is uniformly applied.

Also, the order of steps 1 and 2 may be reversed.

When selecting the "URL location to set" in the next three steps, the virtual keyboard 41 as shown in Figure 5 is displayed on the DTV screen (S80).

At this time, the virtual keyboard 41 is performed through a GUI such as a DTV having a display means.                     

In the next four steps, the user places the cursor over a desired spelling, number or alphabet by using up, down, left, and right keys such as a remote controller or an external input device (S90).

The DTV application software then embeds the location information (X, Y, location) of each keyboard, thereby recognizing the spelling selected as the location information of the current cursor.

The selected spelling is then displayed in the small input window 42 in the upper part of FIG.

The above steps are repeated to complete the input of a desired name (for example, http://www.lge.co.kr/pub/misc/havi/dvcr).

The application software in the DTV converts the name and URL location input by the user into Unicode (S100).

At this time, the name converted to Unicode (S110), the application software in the DTV converts the name entered by the user into Unicode (UNICODE) and writes to the HAVI_User_Preferred_Name field in the SDD data using the DCM :: SetUserpreferredName API of the corresponding device. write) (S120).

The URL location converted to Unicode is written to the DCMPreferredURL in the DCM manager using the DCMManager :: SetPreference API of the DTV (S130).

After that, when the DTV is commanded to install the device, it installs DCM by uploading a Java code unit at a URL location specified by the user.

Then, when the DTV enters the HAVI mode again (S140), the GUID of the entire device is determined and the HAVI_User_Preferred_Name field of the SDD data of the device is read (S150).

Then, as shown in FIG. 4, the converted HAVI home mode is displayed (S160).

And ends through power-off.

In this case, various input devices such as a remote controller or a mouse may be used as a means for inputting a user command, and the name list may be implemented in various ways other than a pull-down menu.

As described above, the method for setting the name of the connected device in the home network system according to the present invention has the following effects.

First, the home network employing the HAVI structure can be set directly to a name that is easy for a user to recognize, and thus device selection of each device can be easily performed.

Secondly, the URL location of the DCM code unit for LAV to upload can be conveniently and easily set using a virtual keyboard, allowing the latest updated DCM code units to be installed.

Third, it may be utilized as a means for receiving a user's input in a home appliance or the like that does not have a keyboard.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.                     

Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims.
