The first control unit 170 is the display device 100 (hereinafter referred to as "display device performance") before the upgrade apparatus 200 is connected and the display device 100 after the upgrade apparatus 200 is connected ( Hereafter, the performance of the 'display system performance' can be tested. The first controller 170 may store at least one of display device performance test results and display system performance test result information in the first storage unit 160.

The first controller 170 controls the first image processor 120 to display respective test result information on the display 130.

Here, the display apparatus performance test and the display system performance test are not necessarily performed continuously. For example, the display device performance test may be performed in advance by a predetermined period or a user's request and stored in the first storage unit 160 before the upgrade apparatus 200 is connected to the first connection unit 140.

In addition, in order to perform the display device performance test in a state where the upgrade apparatus 200 is connected to the first connection unit 140, the test apparatus may be manually removed from the first connection unit 140 to perform a test, or will be described later. The switching unit 180 may be implemented by deactivating the function of the upgrade apparatus 200.

First, a process of performing the display device performance test by manually removing the upgrade device 200 will be described below.

First, when there is a performance evaluation request before and after the connection of the upgrade apparatus 200 through the user input unit 150, the first controller 170 connects the upgrade apparatus 200 to the display unit 130 by the first connection unit 140. You can make the text appear to be removed from the message. Next, when the user manually disconnects the upgrade apparatus 200 and then inputs the disconnection fact through the user input unit 150, the first controller 170 performs the performance of the display apparatus 100, that is, the display apparatus. Test performance. When the display device performance test is completed, the result may be stored in the first storage unit 160. Here, when the display device performance test result is stored in the first storage unit 160 in advance, the display device performance test may be omitted.

After the test of the display apparatus is completed, the first controller 170 may display a guide phrase on the display 130 to guide the connection of the upgrade apparatus 200 again. Thus, after the upgrade apparatus 200 is manually connected to the first connector 140 by the user, the first controller 150 performs a display system performance test in a state where the upgrade apparatus 200 is connected.

After the display system performance test is completed, the first controller 150 may display the display device performance test results and the display system performance test results stored in the first storage 160 together or sequentially on the display 130. One image processor 120 may be controlled.

Here, the display apparatus performance test result information and the display system performance test result information, respectively, the processing speed of the first image processing unit 120 and the second image processing unit 220, the first control unit 170 and the second control unit 270 ) May include information regarding at least one of a processing speed of an application, an execution speed of an application, an executable application, and a newly added function.

In more detail, the test result information is for contrasting the display device performance and the display system performance. The test result information measures the time taken to execute the same application or the time taken to process and display the same image. Run speed can be measured.

The above test result information is only an example, and any test item may be used as long as it can show the display device performance and the display system performance.

In addition, the test result information includes information on executable applications before and after the upgrade apparatus 200 is connected to the display apparatus 100, and information about newly added functions after the upgrade apparatus 200 is connected. It may include.

The first test application for testing the display device performance, the second test application for testing the display system performance, and the third test application for comparing the display device performance and the display system performance with each other include a first storage unit ( 160 may be stored. When the first test application execution command is received from the user through the user input unit 150, the display apparatus performance may be tested, and when the second test application execution command is received, the display system performance may be tested.

Here, the first to third test applications may be stored in the first storage unit 160 and / or the second storage unit 260 of the upgrade apparatus 200 to be described later.

In some cases, the second control unit 270 of the upgrade apparatus 200 may be provided to test the display device performance and the display system performance instead of the first control unit 150. In addition, the image signal for displaying the test result may be provided by the second image processor 220 of the upgrade apparatus 200 instead of the first image processor 120.

In the above description, the user manually removes the upgrade apparatus 200 from the display apparatus 100 in order to perform the above-described two performance tests. Hereinafter, the upgrade apparatus 200 is connected to the display apparatus 100. In the following description, a method of performing display system performance and display device performance test by activating / deactivating the upgrade apparatus 200 will be described.

As shown in FIG. 30, the display system 1 includes a switching unit 180 for selectively activating and deactivating the upgrade apparatus 200 while the upgrade apparatus 200 is connected to the first connection unit 140. It may further include.

The first controller 170 may control the switching unit 180 to deactivate the upgrade apparatus 200 in order to test the performance of the display apparatus before the upgrade apparatus 200 is connected to the display apparatus 100.

The switching unit 180 may include a control signal from the first control unit 170, a first input image signal from the first image receiving unit 110, a first output signal from the first image processing unit 120, and an upgrade apparatus ( At least one of the driving power for driving the 200 may be provided to selectively block transmission to the upgrade apparatus 200.

The display apparatus 100 may further include a first power supply unit 190 for supplying driving power to the upgrade apparatus 200.

The switching unit 180 includes: a first switch 181 for selectively blocking the supply of driving power from the first power supply unit 190 to the upgrade apparatus 200; It may include a second switch 183 for selectively transmitting the first output signal output by the first image processing unit 120 to the display unit 130.

When the first controller 170 performs a performance test on the display apparatus 100 before the upgrade apparatus 200 is connected, the first controller 170 may not supply driving power from the first power supply 190 to the upgrade apparatus 200. The first switch 181 is turned off, and the second switch 183 is turned on so that the first output signal output by the first image processor 120 is transmitted to the display 130. As a result, an image corresponding to the first output signal processed by the first image processor 120 may be transmitted to the display 130. As a result, even when the upgrade apparatus 200 is connected to the display apparatus 100, the upgrade apparatus 200 may be deactivated to perform the display apparatus performance test.

On the contrary, when the performance of the display apparatus 100 is tested while the upgrade apparatus 200 is connected, the first controller 100 turns on the first switch 181 and turns off the second switch 183. To activate the upgrade apparatus 200.

In addition, the switching unit 180 may further include a third switch 185 for selectively blocking supply of at least one of the first input image signal and the first output signal to the upgrade apparatus 200.

Here, the first to third switches 181, 183, and 185 may be installed in the display apparatus 100.

Here, the third switch 185 is a first output signal transmission path between the first image processing unit 120 and the first connection unit 140 and the first input image between the first image receiving unit 110 and the first connection unit 140. It may be disposed on the signal transmission path. The third switch 185 is arranged to block both the first output signal and the first input video signal, but in some cases, the third switch 185 may be provided with a plurality of switches that independently block each signal.

In some cases, the third switch 185 may be disposed on any one path between the first connector 140 and the second connector 240 or between the second connector 240 and the second image processor 220. have.

When the first control unit 170 performs a performance test of the display apparatus 100 before the upgrade apparatus 200 is connected, the first controller 170 turns off the third switch 185 and turns on the second switch 183. As a result, the upgrade apparatus 200 is deactivated.

When the first controller 170 tests the performance of the display apparatus 100 while the upgrade apparatus 200 is connected, the third controller 185 is turned on and the second switch 183 is turned off. As a result, the upgrade apparatus 200 is activated.

In addition, when the second power supply unit 290 is installed in the upgrade apparatus 200 to provide power for driving the upgrade apparatus 200, the switching unit 180 may receive a second power supply from the second power supply unit 290. The electronic device may further include a fourth switch 187 for blocking power supply to at least one of the controller 270 and the second image processor 220.

The fourth switch 187 may be installed in the upgrade apparatus 200.

When the first controller 170 performs a performance test of the display apparatus 100 before the upgrade apparatus 200 is connected, the first controller 170 turns off the fourth switch 187 to cut off the driving power to deactivate the upgrade apparatus 200. Let's do it.

When the first controller 170 tests the performance of the display apparatus 100 while the upgrade apparatus 200 is connected, the first controller 170 turns on the fourth switch 187 to supply the driving power to the upgrade apparatus 200. Activate it.

Here, the first to fourth switches 181, 183, 185, and 187 may include at least one of a transistor, a FET, and a relay, respectively.

The switching unit 180 is for activating / deactivating the upgrade apparatus 200 in a state where the upgrade apparatus 200 is physically connected to the first connection unit 200.

When the upgrade apparatus 200 and the first connection unit 200 are wirelessly connected rather than wired, the first connection unit 200 may be controlled to deactivate the first connection unit 200 including the wireless connection module.

In some cases, the switching unit 180 may be provided in the first connection unit 200. In other words, the first connection unit 200 may include a switch for selectively blocking at least one of the first input image signal, the first output signal, the control signal, and the upgrade apparatus driving power.

31 and 32 show the performance of the display apparatus (display apparatus performance) before the upgrade apparatus is connected and the performance of the display apparatus (display system performance) after the upgrade apparatus is connected, which are displayed on the display unit 130. It is an example of the test results.

31 and 32, the display device performance and the display system performance may be displayed as PIPs on the same screen.

The displayed test result information may include “CPU Speed”, “GPU Speed”, “A Application Execution Speed” and “Screen Resolution”.

The “CPU Speed” item is the processing speed of the first controller 130 and / or the second controller 270 of the upgrade apparatus 200 before and after the upgrade apparatus 200 is connected to the display apparatus 100. Can be. The processing speed is not merely a nominal speed of the first and second controllers 170 and 270, but a speed that measures the time required to execute a specific application or to process a predetermined task such as a specific arithmetic operation.

The “GPU speed” item may be a processing speed of the first image processor 120 and / or the second image processor 220 before and after the upgrade apparatus 200 is connected to the display apparatus 100. The processing speed is not merely the nominal speed of the first image processing unit 120 and the second image processing unit 220, but the time required for processing a specific image processing operation (for example, playing a specific video, recording, displaying a specific screen, etc.). Actual speed.

"A application execution speed" is a measure of the time taken to execute an A application well-known to the user.

The "screen resolution" item may be provided to display the same still image or video so that the user can intuitively feel the improvement of the image quality after connecting the upgrade apparatus. That is, the "screen resolution" item may be classified into "before upgrade" and "after upgrade" to be simultaneously displayed on one screen of the display 130. In more detail, the first controller 170 inputs an image signal or a predetermined broadcast signal from a predetermined image source to the first image processor 120 to perform image processing. The first controller 170 displays the first image B corresponding to the first output signal output by the first image processor 120 on one region of the display 130. Meanwhile, the second controller 270 of the upgrade apparatus 200 inputs the same signal as the image signal or the broadcast signal input to the first image processor 120 to the second image processor 220 of the upgrade apparatus 200. Allows for image processing The second image D corresponding to the second output signal output by the second image processor 220 is displayed on the other area of the display 130. As a result, the first and second images B and D of different image quality, which are output by processing the same image signal or broadcast signal, may be displayed on one screen.

In addition, as shown in FIG. 3, the information about the list of executable apps (applications) before and after the upgrade may also be displayed on the display 130.

For example, it is assumed that the 3D image is realized by connecting the upgrade apparatus 200 to the display apparatus 100 before the upgrade apparatus 200 is connected.

In this case, the 3D-based applications "3D explorer" and "3D game" are displayed in a deactivated state in the "executable application list" of "before upgrade". On the other hand, “3D explorer” and “3D game” are displayed in the “executable program list” of “after upgrade”. Of course, such a feasibility indication method is merely an example and may be variously changed.

In addition, when DMB (Digital Multimedia Broadcasting) is enabled due to the connection of the upgrade apparatus 200, the "DMB" item may be activated and displayed.

Meanwhile, when the user places the cursor C on the deactivated application in FIG. 3, the guide window W displaying information on the upgrade apparatus required for executing the deactivated application is displayed on the display unit 130. It can also be displayed in. The information about the upgrade apparatus may be previously stored in the first storage unit 160 or the second storage unit 260 which will be described later, or may be downloaded from the Internet network through an internet access module such as the communication unit 145. .

Here, the information about the upgrade apparatus may include information about the serial number (N) of the upgrade apparatus and the price (P) of the upgrade apparatus. In some cases, clicking on the upgrade device displayed in the guide window (W) for displaying information on the upgrade device may cause a payment guide window (not shown) necessary to purchase the upgrade device. The user may purchase a specific upgrade device through a payment guide window (not shown).

In the above, the display apparatus performance and the display system performance test are described as being executed in the display apparatus 100. Hereinafter, the performance test and the test result information display processing performed by the upgrade apparatus 200 will be described. do.

The second control unit 270 of the upgrade apparatus 200 tests the performance of the display apparatus before and after the upgrade apparatus 200 is connected to the display apparatus 100, and each test result information is displayed on the display unit. The second image processor may be controlled to be displayed.

Here, when the second image processor 220 is provided to be controlled only by the first controller 170 of the display apparatus 100, the second controller 270 may be omitted as necessary.

The second image processor 220 processes one of the first input image signal of the first image receiver 110 and the first output signal output from the first image processor 120 to output a second output signal.

The second output signal output by the second image processor 220 is again transmitted to the display 130 through the second connector 240 and the first connector 140. As a result, a second image corresponding to the second output signal may be displayed on the display 130. Since the second image processing unit 220 may deepen the function of the first image processing unit 120 or may additionally perform a function that the first image processing unit 120 may not perform, the display unit 130 may include an existing display device. An upgraded image that may not be implemented or difficult to implement at 100 may be displayed.

As an example, the first image processor 120 may not provide a Full HD image, but the second image processor 220 may provide a Full HD image. In addition, the 3D screen may be implemented through the second image processor 220 that the 3D screen may not be provided to the first image processor 120. Of course, these additional and expanded functions are only examples and can be variously changed.

Here, the second image processor 220 may also reprocess the audio signal in addition to the video signal, thereby providing the upgraded audio signal to the display apparatus 100.

Meanwhile, the upgrade apparatus 200 may further include a second image receiver 210 which receives the second input image signal from the broadcast signal or the image supply source 300 and transmits the second input image signal to the second image processor 220.

That is, although the broadcast signal or the video signal has been described as being received or input through the first image receiver 110 of the display apparatus 110, in some cases, as shown in FIG. The image receiver 210 may be provided to receive a broadcast signal or an image signal separately from the display apparatus 110. In this case, when the first controller 170 of the display apparatus 100 detects that the upgrade apparatus 200 is connected to the first connector 140, the first image receiver 110 and the first image processor 120 are detected. ) Can be stopped. In this case, the second input image signal (broadcast signal or image signal) input through the second image receiver 210 is transmitted to the second image processor 220 for image processing and output by the second image processor 220. The second output signal may be transmitted to the display unit 130 through the first connection unit 140 of the display apparatus 100. As a result, the display 130 may display a second image corresponding to the second output signal.

Meanwhile, as another example, when the upgrade apparatus 200 independently receives a broadcast signal or an image signal through the second image receiver 210, the first controller 170 is input through the first image receiver 110. The first image processor 120 may be controlled to process the input signal to output the first output signal to the display 130. Here, the first image corresponding to the first output signal may be displayed as a main screen or a sub screen on the display unit 130. At the same time, when the broadcast signal or the image signal received through the second image receiver 210 is input, the upgrade apparatus 200 processes the second image processor 220 to process the second output signal and displays the second output signal. Can be sent to. As a result, the second image corresponding to the second output signal may be displayed on the display 130 as a sub-screen or a main screen in correspondence with the first image. That is, a first input signal processed through the first input signal input through the first image receiver 110 of the display apparatus 100 and the second input signal input through the second image receiver 210 of the upgrade apparatus 200 is processed. And the second image may be displayed as a picture in picture (PIP) on the display 130, respectively.

When the first controller 170 of the display apparatus 100 detects that the upgrade apparatus 200 is connected, the first controller 170 connects the first image processor 120 and the first image receiver 110 to the first apparatus of the upgrade apparatus 200. It may be controlled jointly with the two control unit 270. As an example, the first controller 170 controls a part of the demultiplexing unit (not shown), the decoding unit (not shown), and the scaling unit (not shown) of the first image processing unit 120, and the second control unit. 270 may be arranged to take charge of the rest of the control.

In some cases, the first controller 170 preferentially controls the first image receiver 110 and the first image processor 120, and the second controller 270 assists the first controller 170. It may be arranged to.

In some cases, on the contrary, the second controller 270 first has the authority to control the first image receiver 110 and the first image processor 120, and the first controller 170 controls the second controller 270. It may be arranged to assist.

Meanwhile, when it is detected that the upgrade apparatus 200 is connected, the first controller 170 of the display apparatus 100 may completely transfer the control function of the first controller 170 to the second controller 270. have. In this case, the first control unit 170 may not perform a control command, but may perform only a function of transmitting a control command between the control objects controlled by the existing first control unit 170 and the second control unit 270. In some cases, a dedicated control communication line for transmitting and receiving a control command between the second control unit 270 and the control target controlled by the existing first control unit 170 may be separately provided.

The second storage unit 260 may store an upgraded operating system than the operating system stored in the first storage unit 160, and the first controller 170 or the second controller 270 may be stored in the first storage unit 160. You can update the stored operating system with the upgraded operating system and run the updated operating system. In some cases, the operating system of the second storage unit 260 may be driven instead of the operating system stored in the first storage unit 160.

Meanwhile, the switching unit 180 selectively blocks at least one of an image signal, a control signal, and a power output from the display apparatus 100 being input to the second image processing unit 220 and the second control unit 270. The purpose is as described above. Here, in FIG. 30, the first to third switches 181, 183, and 185 are illustrated in the display apparatus 100, but in some cases, the first to third switches 181, 183, and 185 are upgraded. It may be installed in the device 200.

The second controller 270 may deactivate the upgrade apparatus 200 by controlling the switching unit 180 to test the performance of the display apparatus before connecting the upgrade apparatus. That is, the second controller 270 may control at least one of the first to third switches 181, 183, and 185 installed in the display apparatus 100.

Here, the second controller 270 may directly receive the display apparatus performance and the display system performance test request command from the user input unit 150, and receive the command via the first controller 130 and the first connection unit 140. It may be.

The upgrade apparatus 200 includes a second power supply unit 290 for supplying driving power to the second controller 270 and the second image processor 220; Switching unit 187 for selectively blocking the supplied driving power supplied from at least one of the second control unit 270 and the second image processing unit 220 from the second power supply unit 290, precisely the fourth switch ( 187) may be further included.

When there is a request for deactivation, the second controller 270 may control the switching unit 187 to block driving power from being supplied to at least one of the second controller 270 and the second image processor 220. . Thereby, the upgrade apparatus 200 can be deactivated.

On the contrary, when the activation command of the first controller 170 of the display apparatus 100 is received through the second connector 240, the switching unit 187 supplies the driving power to the second controller 270 and the second image. Supply to the processing unit 220.

The switching unit 180 may be provided in the second connection unit 240. That is, the third switch 185 and the first switch 181 shown in FIG. 1 may be provided in the second connector 240. That is, the second connector 240 controls at least one of the first output signal, the first input video signal, the control signal, and the driving power by controlling at least one of the first controller 170 and the second controller 270. Any one may be provided to be selectively supplied to the upgrade apparatus 200.

Meanwhile, the switching unit 180 may be controlled by either one of the first controller 170 and the second controller 270, but may be simultaneously controlled by both. In this case, priority is given to any one of the first control unit 170 and the second control unit 270 so that one of them may predominantly control the switching unit 180 and the other auxiliary control the switching unit 180. Can be. In some cases, the first control unit 170 of the display apparatus 100 is in charge of the control unit installed in the display apparatus 100 among the switching unit 180, and the second control unit 270 is installed in the upgrade apparatus 200. You can also let) take over the control.

If the previous update fails, the update file is transmitted, and after the update is executed, the update completion response is checked (S1507). At this time, if there is no update completion response, transaction management unit 320 records the update failure (S1508).

If there is no update failure in step S1502, it is checked whether the file transfer has failed in the previous update (S1503). At this time, if there is no file transfer failure in the previous update, since the update file is in the transmitted state, after executing the update, the update completion response is checked (S1507).

If the file transfer fails in step S1503, the version of the software is checked and the update file is transmitted to the requesting device (S1504). After transmitting the update file, check the file transfer complete response (S1505), if there is no file transfer complete response, generate and send a message to check the physical connection between the IP device 100-1 and the upgrade apparatus 200, The transaction manager 320 records a file transfer failure (S1506).

In step S1505, there is a file transfer completion response, and the update is executed and the update completion response is checked (S1507). At this time, if there is no update completion response, the transaction manager 320 records the update failure (S1508). If there is an update completion response, all failure records are deleted (S1509).

As such, the display system 1 according to the eighth embodiment of the present invention includes the display apparatuses 100-1, 100-2, 100-3 providing hardware and the upgrade apparatuses 100-1, 100- providing software. 2, 100-3) by physically separating the display device (100-1, 100-2, 100-3), that is, even if the specifications of the IP devices are different from each other can be universally updated S / W, and update It is possible to perform conveniently and conveniently in a batch. In addition, it is possible to quickly deal with the exceptional situation that occurs during general software update, that is, exceptional situation between the physically separated IP device and the upgrade device, for example, unplugging, impact.
