BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display apparatus, and more particularly, to a commercial display apparatus used in a place such as a hotel and a control method thereof.

The display device is not only used in homes or offices, but also widely used for commercial purposes in airports, stations, and hotels.

1 is a view showing a display system according to the prior art.

Referring to FIG. 1, a display system for commercial use includes a host server 10, and connects the host server 10 and the plurality of display apparatuses 20 through a communication cable, and thus the host server ( In step 10), the setting values are transmitted to the display apparatus 20 at one time.

In addition, each display apparatus 20 receives a data signal received through the data cable, and updates previously stored data using the received data signal.

At this time, each display device 20 has a built-in modem for communication with the host server 10, and receives the data signal using a low frequency not used in the broadcast channel.

Accordingly, each display apparatus 20 sets all setting items by using the received data signal without a separate setting process.

However, the display system according to the related art as described above must be provided with expensive server equipment in order to reduce the time and cost of setting the setting items of each display device 20.

In addition, since data signals are simultaneously transmitted from a central server to a plurality of display apparatuses, there is a problem in that a display apparatus cannot receive the data signals according to the installation position of the display apparatuses.

In addition, since the menus of the display apparatuses have different values and configurations for each model, the server must manage setting values for each model. When the setting values for each model cannot be managed, normal settings of the display apparatuses may be performed. There is no problem.

In an embodiment according to the present invention, the setting of a plurality of display apparatuses can be easily performed without expensive server equipment.

A control method of a display apparatus according to an embodiment of the present invention includes the steps of receiving a data signal; Updating previously received and stored data with data included in the received data signal; Installing a use environment of a display apparatus using the updated data; And transmitting the received data signal to at least one neighboring display device.

The display apparatus may further include a communication unit configured to receive a data signal transmitted from the outside and transmit the received data signal to a neighboring adjacent display apparatus; A storage unit which stores a data signal received through the communication unit; And a controller configured to update data previously received and stored in the storage unit with data received through the communication unit, and to install a usage environment using the updated data, wherein the controller is configured to receive the received data signal. Is transmitted to at least one neighboring display device neighboring through the communication unit.

According to the embodiment of the present invention, since it has the same effect of the existing server-client structure without expensive servers, it is possible to minimize the time and cost required for setting the display device, and all display devices become masters to display other nearby displays. Since the data signal is sent to the device, it is possible to solve the problem of not receiving the data signal due to the limitation of the position.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. However, the spirit of the present invention is not limited to the embodiments presented, and other embodiments included within the scope of other inventive inventions or the scope of the present invention can be easily made by adding, changing, or deleting other elements. I can suggest.

The term used in the present invention is selected as a general term widely used as possible at present, but in certain cases there is also a term arbitrarily selected by the applicant, in which case the meaning is described in detail in the description of the invention, the name of a simple term It should be clear that the present invention is to be understood as a meaning of terms.

2 is a diagram illustrating a display system according to an exemplary embodiment of the present invention.

Referring to FIG. 2, the display system 100 includes a first display apparatus 110, a second display apparatus 120, a third display apparatus 130, and an Nth display apparatus 140.

The display devices may be installed in hotels, airports, hospitals, and the like.

The plurality of display apparatuses are connected to each other through an RF cable, and may transmit its data to a neighboring display apparatus or receive data transmitted from a neighboring display apparatus through the RF cable.

Each of the display devices has a built-in RF modem (BLAN) for communicating with other adjacent display devices, and may transmit or receive data using different frequencies in a low frequency band through the RF modem.

In this case, the data to be transmitted or received includes channel map data, installation data, menu setting values, firmware data, and the like. Accordingly, each display device has a function of transmitting the data to an adjacent display device.

In addition, each of the display apparatuses has a function of checking a version of pre-stored data and a version of currently received data, and thus determines whether to install a usage environment based on the currently received data according to the version check result.

In an embodiment according to the present invention, one display device becomes a master device, and thus the master device transmits the latest data to another adjacent display device.

In addition, the display device receiving the data checks the version of the received data and installs the use environment. Accordingly, when the installation of the use environment is completed, the display device itself becomes a master again and the other display device is adjacent to the display device. Send the received data.

That is, in the present invention, one master display apparatus transmits its latest data to other display apparatuses using an RF modem. Then, when the slave display device receives data of a higher version than its own version, the slave display device updates the previously stored data using the received data, and then becomes a master display device to update the new slave display devices with the latest data. To pass.

In the case of the installer, when the latest setting value is put on an unspecified display device, the display device becomes a master display device and starts to transmit the latest data to other display devices, and has the same effect as a conventional server-client.

Therefore, even if there is no expensive server has the same effect as the server-client using the current display device structure can minimize the time and cost according to the installation environment. In addition, since display apparatuses located nearby become master display apparatuses and transmit data to other display apparatuses, it is possible to prevent a case in which data cannot be received due to location limitations.

3 is a diagram illustrating a configuration of a display apparatus according to an exemplary embodiment of the present invention.

Referring to FIG. 3, the display apparatus may include a broadcast receiver 210, a demodulator 220, an image decoder 230, a display 240, a storage 250, an RF modem 260, and a controller 270. Include.

When the above display device is installed in a hotel, a pay per view (PPV) service, a room service, a hotel-related information service, a reservation service, and a check-out information service ( Various services provided in the hotel, such as checkout information, entertainment information, or game services, may be provided.

The broadcast receiver 210 may be configured as a tuner, and receives a video signal corresponding to a broadcast channel selected by a user among broadcast signals transmitted from the head-and-device (generally, an audio signal of the broadcast channel may also be received together). have).

The demodulator 220 may correct an error of a video signal of a broadcast channel received by the broadcast receiver 210 and convert the video signal into a transport stream (TS), and the video decoder 230 may receive the received signal. The decoded video signal and the audio signal may be decoded to be output from the display unit 240.

The display unit 240 displays an image decoded through the image decoder 230. The display unit 240 may display an image using various display methods, such as a liquid crystal display (LCD), a plasma display panel (PDP), an electro luminescent display (ELD), and a vacuum fluorescent display (VFD).

The storage unit 250 stores information generated during the operation of the display device, information necessary for the operation, and the like. For example, the storage 250 may be embodied as an EEPROM (Electrically Erasable Programmable Read-Only Memory).

The RF modem 260 is connected to at least one adjacent display device and receives a data signal transmitted from the adjacent display device or transmits a data signal to the adjacent display device.

That is, a data signal for installation of a usage environment may be transmitted through a radio frequency (RF) cable installed to transmit a broadcast signal to a display device disposed in each room in the hotel.

In this case, the data signal may be transmitted through a data dedicated channel independent from the broadcast channel through which the broadcast signals are transmitted.

In addition, the data transmission channel is separately divided into a data transmission channel for data transmission and a data reception channel for data reception so that data can be transmitted and received freely.

The controller 270 controls the overall operation of the display apparatus.

In particular, the controller 270 receives a data signal transmitted from the outside, and updates previously stored data according to the version of the received data signal.

In addition, the controller 270 installs a usage environment by using the updated data, and transmits the data used to install the usage environment to another neighboring display apparatus.

In this case, the control unit 270 may transmit the data only to the adjacent display device having the same model information as its own. Alternatively, the controller 270 may transmit the data signal only to the display device in which the data having a lower version than the data version is stored.

Description of this will be described in more detail with reference to the following.

4 to 7 are flowcharts for explaining step-by-step control method of the display apparatus according to an embodiment of the present invention. Hereinafter, the control method of the display apparatus illustrated in FIGS. 4 to 7 will be described in connection with the components of FIG. 3.

First, if there is the latest data to be updated, the administrator transmits the latest data to any one of the plurality of display apparatuses. In this case, the latest data is connected to an external interface unit (not shown) of the display device, and thus a data signal stored in an external storage medium is transmitted to the display device.

4 is a view illustrating an operation of transmitting the latest data only to any one of a plurality of display apparatuses using an external storage medium.

Referring to FIG. 4, an external storage medium is connected to an external interface unit (not shown). Accordingly, the external interface unit extracts data stored in the external storage medium and transmits the data stored in the external storage medium (step 410).

If the data is delivered, the controller 170 checks version information of the data (step 420). The data includes its own version information.

If the determination result (step 420), the version information of the data is lower than the version of the pre-stored data, the controller 170 ignores the data.

However, if the version information of the data is higher than the previously stored version of the data, the controller 170 updates the previously stored data in the storage unit 150 using the received data (step 440).

In addition, the controller 170 installs a use environment of the display apparatus using the updated data (step 450). That is, the controller 170 updates the prestored channel map with the channel map included in the data. Similarly, installation, menu setting and firmware update are performed.

Thereafter, the controller 170 transmits the data to the neighboring adjacent display apparatus through the RF modem 160 (step 460).

5 and 6 are detailed flowcharts of the transmission step (step 460).

First, the controller 170 inserts its identification information into the data to be transmitted (step 510). That is, information indicating that the origin of the transmitted data is itself is inserted into the data.

In operation 520, the controller 170 requests version information of pre-installed data from adjacent display devices. That is, it transmits a signal requesting a version of the data used to install the use environment of the adjacent display device.

When a version corresponding to each display apparatus is received according to the request signal transmission, the controller 170 identifies a neighboring display apparatus that transmits a version lower than the version of the data to be transmitted (operation 530). The controller 170 checks adjacent displays in which a usage environment is installed with data having a version lower than that of the data to be transmitted.

In operation 540, the controller 170 transmits the data only to the checked adjacent display device.

In addition, referring to FIG. 6, the controller 170 inserts its identification information into the data to be transmitted (step 610). That is, information indicating that the origin of the transmitted data is itself is inserted into the data.

Thereafter, the controller 170 checks model information of previously stored adjacent display devices, and accordingly, checks adjacent display devices having the same model information as their own model information (step 620). That is, the firmware data included in the data has different data for each model, thereby transmitting the data only to the display apparatus of the same model as the own model information.

If the adjacent display device is identified, the controller 170 transmits the data only to the identified display device (step 630).

7 is an operation flowchart corresponding to a case where data transmitted through an adjacent display apparatus is received.

Referring to FIG. 7, when the data transmitted through the adjacent display apparatus is received through the RF modem 160, the controller 170 analyzes the received data (step 710).

In operation 720, the controller 170 determines whether its own identification information is included in the received data.

 That is, the controller 170 determines whether the received data is data previously transmitted to the adjacent display device.

If the identification information is included in the received data, the controller 170 stops the transmission of the received data and deletes the data.

On the contrary, if the identification information is not included in the received data, the controller 170 checks the version of the received data (step 730).

When the version of the data is confirmed, the controller 170 determines whether the version of the data is higher than the version of the previously stored data (step 740).

Then, if the version of the data is lower than the version of the pre-stored data, the controller 170 ignores the received data, or otherwise stores the received data (step 750).

The controller 170 installs a usage environment using the stored data (step 760).

In operation 770, the controller 170 transmits the stored data to the neighboring adjacent display apparatus. In this case, the control unit 170 transmits the data while maintaining the identification information of another display apparatus already included in the data without inserting its own identification information into the data.

According to the embodiment of the present invention, since it has the same effect of the existing server-client structure without expensive servers, it is possible to minimize the time and cost required for setting the display device, and all display devices become masters to display other nearby displays. Since the data signal is sent to the device, it is possible to solve the problem of not receiving the data signal due to the limitation of the position.

In addition, although the preferred embodiment of the present invention has been shown and described above, the present invention is not limited to the above-described specific embodiment, the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Of course, various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
