Hereinafter, a specific embodiment for upgrading the display device 33100 by the upgrading device 33200 will be described with reference to Fig. 17 is a flowchart showing a method of upgrading the image processing process of the display device 33100 by the upgrade device 33200 in the display system 331 according to the present embodiment.

17, the display device 33100 receives a predetermined signal from the image source 33300, for example, a broadcast signal (33411), and transmits it to the image processing process 33412, 33413, 33414). The examples of the image processing processes 33412, 33413, and 33414 shown in the figures are merely illustrative of a few examples for more concise representation of the embodiments of the present invention, and in fact all of the image processing processes implemented in the display device 33100 It is not shown.

The display device 33100 performs demultiplexing for classifying the received broadcast signal into a video signal, a voice signal, and additional data (33412). The display device 33100 processes the demultiplexed signals. For example, the display device 33100 decodes the video signal into a predetermined video format (33413). The display device 33100 scales the decoded image signal to a predetermined resolution to display the decoded image signal on the display unit 33130 as an image (33414), and displays the scaled image signal as an image (33415).

Among the series of sequences, the upgrading device 33200 is provided so as to be capable of performing the process 33423 corresponding to the decoding process 33413 of the display device 33100. [ The decoding process 33423 that can be performed by the upgrade apparatus 33200 is the same in terms of operation as decoding compared to the decoding process 33413 that the display apparatus 33100 is capable of performing, 33423) may be performed to improve the image processing process.

For example, in the former 33423, it is possible to process a video signal of a resolution higher than a level that can not be processed by the latter 33413, to process a video signal of a format that can not be processed by the latter 33413, ) Can be applied to the video signal.

The sequence of the image processing process according to the present embodiment is performed after the demultiplexing step 33412 and the decoding step 33413 of the display device 33100 according to the control of the first control part 33160 or the second control part 33260 The decoding step 33423 of the upgrade apparatus 33200 is performed. After the decoding step 33423 of the upgrade device 33200, a scaling step 33414 is performed.

According to this sequence, a video signal and a control signal are transmitted and received between the display device 33100 and the upgrade device 33200, and this is performed under the control of the first control unit 33160 or the second control unit 33260.

Unlike the case of FIG. 17 in which some processes are replaced in the image processing process, when the second image processing unit 33220 of the upgrading apparatus 33200 replaces the first image processing unit 33120 of the display apparatus 33100 This will be described with reference to Fig. 18 below. 18 is a configuration block diagram illustrating a process of transmitting a video signal received by the first connection unit 33110 in the display system 331 according to the present embodiment.

18, when the upgrade apparatus 33200 is not connected to the display apparatus 33100, the video signal is received by the first connection unit 33110 (33431), and is transmitted to the first image processing unit 33120 (33432). The first image processing unit 33120 processes the image signal and outputs the image signal to the display unit 33130 (33433), whereby the display unit 33130 displays the image signal processed by the first image processing unit 33120 as an image do.

When the upgrade device 33200 is connected to the display device 33100, the video signal is received by the first connection unit 33110 (33431), and then transmitted to the second image processing unit 33220 other than the first image processing unit 33120. [ (33434). The second image processor 33220 performs an image processing process on the image signal in place of the first image processor 33120 and the image signal processed by the second image processor 33220 is transmitted to the display device 33100 again (33435).

The video signal is bypassed not to be transmitted to the first image processing unit 33120 and is transmitted to the display unit 33130 (33436), whereby the display unit 33130 processes the video signal by the second image processing unit 33220 The video signal is displayed as an image.

On the other hand, when the display device 33100 and the upgrade device 33200 are connected, the second control unit 33260 disables the first control unit 33160 and outputs the first image processing unit 33120 and the second image processing unit 33220 Can be controlled. Alternatively, when the operating system stored in the second storage unit 33250 is version-upgraded from the operating system stored in the first storage unit 33150, the operating system of the first storage unit 33150 is stored in the second storage unit 33250 Or to update the operating system of the first storage unit 33150 or to operate the operating system of the second storage unit 33250 instead of the operating system of the first storage unit 33150. [

According to such a configuration, the upgrading apparatus 33200 according to the present embodiment can upgrade the display apparatus 33100.

On the other hand, under the structure of the display device 33100 and the upgrading device 33200 as in the above-described embodiment, a plurality of upgrading devices 33200 may be replaced with one display device 33100. 19 is an exemplary view showing a case in which two upgrade devices 201 and 202 are selectively connected to the display device 33100. Fig.

As shown in Fig. 19, any one of the first upgrading device 33201 and the second upgrading device 33202 can be selectively connected to the display device 33100 to be upgraded by the user. Detailed configurations of the first upgrading device 33201 and the second upgrading device 33202 can be applied to the configuration of the upgrading device 33200 described above with reference to FIG. 16, and detailed description will be omitted.

When the user connects the first upgrading device 33201 to the display device 33100 (A), the first upgrading device 33201 upgrades the display device 33100. At this time, the first upgrading device 33201 performs the upgrade related operation based on the self-stored environment setting information.

This configuration information includes various pieces of data / information used in the display system 33331, and includes, for example, user profile information, environment setting values set by the user on the display device 33100, A list of broadcast channels, and the like. That is, the environment setting information is not information or data limited to a specific type, but may be information necessary for the operation of the display system 331.

While the upgrade by the first upgrading device 33201 is being performed in accordance with the connection of the first upgrading device 33201 and the display device 33100, the environment setting information stored in the first upgrading device 33201 may be various factors . ≪ / RTI >

For example, the profile of the user may be changed, the brightness level or the audio output level of the display image may be changed, the new application may be installed or the already installed application may be deleted , The list of channels preferred by the user may be changed.

When the environment setting information is changed during the upgrade, the first upgrade device 33201 stores the changed environment setting information. This configuration information is stored in the memory (see 33250 in Fig. 16) of the first upgrading apparatus 33201 and is stored in the first controller 33160 of the display apparatus or the second controller of the first upgrading apparatus 33201 260).

If connection between the first upgrading device 33201 and the display device 33100 is performed again after the connection between the first upgrading device 33201 and the display device 33100 is released (A) (33201) performs upgrade based on the pre-stored environment setting information. Thereby, the display system 331 can return the changed usage environment to the user as it is, even if the connection between the first upgrading device 33201 and the display device 33100 is disconnected once and then reconnected have.

After the connection between the first upgrading device 33201 and the display device 33100 is released, the second upgrading device 33202 other than the first upgrading device 33201 may be connected to the display device 33100 (B). In this case, the second upgrading device 33202 performs upgrade based on the environment setting information stored in itself.

The environment setting information of the second upgrading device 33202 is different from the environment setting information stored in the first upgrading device 33201 because the environment setting information is changed during the preceding A step, that is, during the upgrade by the first upgrading device 33201. Therefore, in step B, since the environment setting information changed in the preceding step A can not be used, the usage environment of the display system 331 configured in step A is not maintained in step B and is reset.

The first control unit 33160 may transmit environment setting information that is changed during the upgrade operation performed by the first upgrading apparatus 33201 and stored in the first upgrading apparatus 33201 to the display apparatus 33100 in the first storage unit 33150 of the first storage unit 33150. When the second upgrading device 33202 is connected to the first connecting part 33110, the first controlling part 33160 transmits the environment setting information stored in the first storing part 33150 to the second upgrading device 33202 By updating the stored environment setting information, the second upgrading device 33202 performs the upgrade operation based on the updated environment setting information.

Thereby, even if the connection to the display device 33100 is replaced with the first upgrading device 33201 to the second upgrading device 33202, the use environment provided by the first upgrading device 33201 can be also used in the second upgrading device 33202 Can be maintained and provided.

In the present embodiment, a case has been described in which the first control unit 33160 of the display device 33100 is used to perform the change storage, backup storage and update of the environment setting information. However, the present invention is not limited thereto, May be one of the display device 33100, the first upgrading device 33201, and the second upgrading device 33202 according to the designing method.

For example, when connecting the display device 33100 and the first upgrading device 33201, the subject storing the changed environment setting information in the first upgrading device 33201 and storing the changed environment setting information in the display device 33100 is the first And the second control unit (refer to 33260 in Fig. 16) of the upgrading apparatus 33201. [ Alternatively, when connecting the display device 33100 and the second upgrading device 33202, the subject updating the environment setting information previously stored in the second upgrading device 33202 with the environment setting information stored in the display device 33100 as backup And may be the second control unit (see 33260 in Fig. 16) of the second upgrading apparatus 33202. [

16) of the first upgrading device 33201 and the second upgrading device 33202 does not mean the same configuration, but the second controlling part 33260 of FIG. Means that the configuration corresponding to the first upgrading device 33201 and the second upgrading device 33202 are provided in the first upgrading device 33201 and the second upgrading device 33202, respectively.

On the other hand, the operation of backing up the environment setting information to the display device 33100 when the first upgrading device 33201 and the display device 33100 are connected is performed in real time in response to the change of the environment setting information, Can be performed at the time of occurrence of an event.

Hereinafter, a method of backing up and storing the environment setting information in real time in accordance with the change of the environment setting information at the time of connecting the first upgrading apparatus 33201 and the display apparatus 33100 will be described with reference to FIG. FIG. 20 is a control flowchart showing this process, and sets a state in which there is no backup setting stored in the display device 33100 as an initial state.

As shown in FIG. 20, the first upgrading apparatus 33201 is connected to the display apparatus 33100 in accordance with the connection of the first upgrading apparatus 33201 to the display apparatus 33100 (S33100) (S33110).

If the environment setting information is changed during the upgrade (S33120), the display apparatus 33100 stores the changed environment setting information in the first upgrade apparatus 33201 (S33130). In step S33140, the display device 33100 backs up the changed configuration information, that is, the environment setting information stored in the first upgrade device 33201, to the display device 33100 at the present time.

On the other hand, a method of backing up environment setting information according to a specific event when the first upgrading device 33201 and the display device 33100 are connected will be described with reference to Fig. FIG. 21 is a control flowchart showing this process, and the state proceeding to the step S33110 of FIG. 20 is set as an initial state.

21, when the environment setting information is changed during the upgrade by the first upgrading device 33201 (S33200), the display device 33100 stores the changed environment setting information in the first upgrading device 33201 (S33210). Then, the display device 33100 stores an information change history indicating that the configuration information has been changed (S33220).

When an event for turning off the system power is generated from a specific event, for example, the user input unit 33140 (S33230), the display apparatus 33100 determines whether the information change history is stored (S33240).

If the information change history is stored, the display device 33100 backs up the environment setting information of the first upgrading device 33201 and stores it in the display device 33100 (S33250). When the backup storage is completed, the display device 33100 deletes the information change history (S33260) and turns off the system power (S33270).

On the other hand, if the information change history is not stored, the display apparatus 33100 turns off the system power (S33270).

According to this process, the environment setting information changed and stored in the first upgrading device 33201 can be backed up and stored in the display device 33100. [

As to the manner in which the upgrade is performed as the second upgrade apparatus 33202 is connected to the display apparatus 33100 while the environment setting information related to the first upgrade apparatus 33201 is backed up in the display apparatus 33100, This will be described below with reference to FIG. 22 is a control flowchart showing this process.

As shown in FIG. 22, when the second upgrading apparatus 33202 is connected (S33300), the display apparatus 33100 judges whether or not the connected second upgrading apparatus 33202 has been connected to the previous step S33310).

Here, the previous step is a step in which the upgrading apparatus 33201 is connected immediately before the second upgrading apparatus 33202 is connected in step S33300, that is, in the case of this embodiment, the first upgrading apparatus 33201 and the display apparatus (33100) is connected and upgraded.

The first upgrading device 33201 and the second upgrading device 33202 each include identification information. Upon connection of the first upgrading device 33201, the display device 33100 acquires and stores the identification information from the first upgrading device 33201. The display device 33100 compares the identification information of the previously stored first upgrade device 33201 with the identification information of the newly acquired second upgrade device 33202 in step S33310 so that the upgrade device newly connected in step S33300 It is possible to determine whether the first upgrading apparatus 33201 is connected to the first upgrading apparatus 33201 or the second upgrading apparatus 33202 is connected.

Alternatively, when the operation main body in step S33310 is the second upgrading apparatus 33202, the second upgrading apparatus 33202 acquires the identification information of the display apparatus 33100 contrary to the above case. The first upgrading device 33201 or the second upgrading device 33202 acquires the identification information of the display device 33100 when the display device 33100 is connected and the identification information acquired from the newly connected display device 33100 It is possible to determine whether or not the corresponding display device 33100 is the previously connected display device 33100 by comparing the previously stored identification information.

If the display device 33100 determines that the newly connected second upgrading device 33202 is different from the previously connected first upgrading device 33201, the display device 33100 determines whether there is environment setting information stored in the display device 33100 (S33320 ).

If the backed-up environment setting information is stored in the display device 33100, the display device 33100 updates the environment setting information previously stored in the second upgrading device 33202 with the environment setting information stored in the display device 33100 (S33330 ). Thus, the second upgrading apparatus 33202 performs the upgrade based on the updated environment setting information (S33340).

On the other hand, if it is determined in step S33310 that the device is connected to the previous step, or if it is determined in step S33320 that the environment setting information stored in the display device 33100 is not backed up, the display device 33100 displays the upgrade devices 33201 and 33202 (Step S33350). In step S33350,

On the other hand, in step S33310, the display device 33100 can additionally determine whether the second upgrading device 33202 is not a product that is formally manufactured or has a problem in compatibility with the display device 33100.

Hereinafter, the configuration of the upgrading apparatus 44100 will be described.

The upgrading apparatus 44100 includes a second connection section 44210 connected to the first connection section 44110 of the display apparatus 44100 and a second connection section 44210 capable of processing a process corresponding to at least a part of the image processing process of the first image processing section 44120 A second storage unit 44250 for storing unlimited data / information, and a second control unit 44260 for controlling all operations of the upgrade apparatus 44100.

The second connection portion 44210 is connected to the first connection portion 44110, thereby enabling communication between the upgrade device 44100 and the display device 44100. The second connection portion 44210 is provided according to a standard corresponding to the first connection portion 44110 so as to be connected to the first connection portion 44110. The second connection portion 44210 includes at least one of a plurality of connection terminals May be connected to connection terminals (not shown).

For example, the second connection portion 44210 is connected to the HDMI terminal (not shown) so that a video signal is transmitted and received between the display device 44100 and the upgrade device 44100 from among a plurality of connection terminals (not shown) of the first connection portion 44110 And a USB terminal (not shown) to transmit and receive data and power, respectively. However, this is only one example, and the connection manner between the first connection unit 44110 and the second connection unit 44210 may be implemented in various forms other than the above-described embodiment.

The second image processing unit 44220 can perform a second process corresponding to the first process for at least a part of the first process performed by the first image processing unit 44120 in the display device 44100. [ The first process and the second process are referred to for the sake of convenience, and may also be one unit process or a plurality of unit processes. The second process is functionally improved compared to the first process, which is realized by improvement of hardware such as chipset or by improvement of software such as algorithm / executable code / program.

The second image processing section 44220 may replace the first process in accordance with the control of the first control section 44160 or the second control section 44260 at the time of connecting the display device 44100 and the upgrade device 44100, . As such, in the image processing process, the second process functionally improved as compared to the first process is performed instead of the first process, thereby improving the overall image processing process. Detailed embodiments related to this will be described later.

The second storage unit 44250 stores unlimited data. The second storage unit 44250 is implemented as a non-volatile memory such as a flash memory, a hard-disc drive, or the like. The second storage unit 44250 is accessed by the first control unit 44160 or the second control unit 44260, and reading / recording / modification / deletion / update of data by the second control unit 44260 is performed. Meanwhile, the first storage unit 44150 may be accessed by the second control unit 44260 as well as the first control unit 44160 according to the implementation method.

The second control unit 44260 controls the connection operation between the display device 44100 and the upgrade device 44100 for performing the entire image processing process. The second controller 44260 and the first controller 44160 may be implemented as a CPU and if the second controller 44260 can perform an enhanced function than the first controller 44160, 1 control unit 44160 and replace the first control unit 44160 to control the operation of the entire display system 441. [ Alternatively, the second control unit 44260 may control the operation of the entire display system 441 together with the first control unit 44160.

On the other hand, when the display device 44100 and the upgrade device 44100 are connected, the second control unit 44260 disables the first control unit 44160 and outputs the first image processing unit 44120 and the second image processing unit 44220 Can be controlled. Alternatively, when the operating system stored in the second storage unit 44250 is version-upgraded from the operating system stored in the first storage unit 44150, the operating system of the first storage unit 44150 is stored in the second storage unit 44250 To update the operating system of the second storage unit 44250 and to run the updated operating system or to operate the operating system of the second storage unit 44250 instead of the operating system of the first storage unit 44150. [

According to such a configuration, the upgrading apparatus 44100 according to the present embodiment can upgrade the display apparatus 44100.

On the other hand, under the structure of the display device 44100 and the upgrading device 44100 as in the above-described embodiment, a plurality of upgrade devices 201 and 202 may be replaced and used for one display device 44100. 25 is an exemplary view showing a case in which two upgrade devices 44201 and 44202 are selectively connected to the display device 44100. Fig.

As shown in Fig. 25, any one of the first upgrading device 44201 and the second upgrading device 44202 may be selectively connected to the display device 44100 to be upgraded by the user. Detailed configurations of the first upgrading device 44201 and the second upgrading device 44202 can be applied to the configuration of the upgrading device 44100 described above with reference to FIG. 24, and detailed description will be omitted.

When the user connects the first upgrading device 44201 to the display device 44100 (A), the first upgrading device 44201 upgrades the display device 44100. At this time, the first upgrading device 44201 performs the upgrade-related operation based on the self-stored setting information.

This configuration information includes various data / information used in the display system 441, and includes, for example, user profile information, environmental information values set by the user on the display device 44100, Installed applications, a list of broadcast channels, and the like. That is, the setting information is not information or data that is limited to a specific kind, and may be information necessary for the operation of the display system 441.

While the upgrade by the first upgrading device 44201 is being performed in accordance with the connection of the first upgrading device 44201 and the display device 44100, the setting information stored in the first upgrading device 44201 may be various factors Lt; / RTI >

For example, the profile of the user can be changed, the brightness level or the audio output level of the display image can be changed, the new application can be installed or the already installed application can be deleted, The list of channels preferred by the user may be changed.

When the setting information is changed during the upgrade, the first upgrading device 44201 stores the changed setting information on its own. This setting information is stored in the memory (see 44250 in Fig. 24) of the first upgrading device 44201 and is stored in the memory of the first controlling part 44160 of the display device 44100 or the second controlling part of the first upgrading device 44201 24, 44260).

If connection between the first upgrading device 44201 and the display device 44100 is performed again after the connection between the first upgrading device 44201 and the display device 44100 is released (A) (44201) performs the upgrade based on the self-stored setting information. Thereby, the display system 441 can return the changed usage environment to the user as it is, even if the connection between the first upgrading device 44201 and the display device 44100 is disconnected once and then reconnected have.

However, after the connection between the first upgrading device 44201 and the display device 44100 is released, the second upgrading device 44202 other than the first upgrading device 44201 may be connected to the display device 44100 (B). In this case, the second upgrading device 44202 performs upgrade based on the setting information stored in itself.

However, the setting information of the second upgrading device 44202 is different from the setting information stored in the first upgrading device 44201 because the setting information is changed in the preceding step A, that is, during the upgrade by the first upgrading device 44201. [ Therefore, in step B, since the setting information changed in the preceding step A can not be used, the usage environment of the display system 441 configured in step A is not maintained in step B and is reset.

Thus, according to the present embodiment, the display device 44100 operates as follows.

The display device 44100 is in a state in which it is communicably connected to a separate external device 44310 in addition to the first upgrading device 44201 or the second upgrading device 44202 (C).

The display device 44100 backs up the setting information stored in the first upgrading device 44201 during the upgrade operation (A) performed by the first upgrading device 44201 to the separate external device 44310. When the display device 44100 is connected to the second upgrading device 44202 by the first upgrading device 44201 and is connected to the external device 44310, The second upgrading device 44202 updates the setting information previously stored in the second upgrading device 44202 with the setting information backed up in the external device 44310 so that the upgrade is performed based on the setting information, Thereby performing an upgrade operation.

Thereby, even if the connection to the display device 44100 is replaced with the first upgrading device 44201 to the second upgrading device 44202, the use environment provided by the first upgrading device 44201 can be also used in the second upgrading device 44202 Can be maintained and provided.

Here, the external device 44310 according to the present embodiment is described as being a server 44310 connected to the display device 44100 via a network, but the spirit of the present invention is not limited thereto. For example, the external device 44310 may be implemented by various kinds of electronic devices or storage devices locally connected to the display device 44100 in addition to the server. It is also possible that the external device 44310 is connected to the upgrading devices 44201 and 44202 instead of the display device 44100.

In the present embodiment, the case where the first control unit 44160 of the display device 44100 changes, stores, and stores the setting information is performed, but the idea of the present invention is not limited thereto. It may be any one of the display device 44100, the first upgrading device 44201, and the second upgrading device 44202 according to the designing method.

For example, when connecting the display device 44100 and the first upgrading device 44201, the entity storing the changed setting information in the first upgrading device 44201 and storing the changed setting information in the external device 44310 is a first upgrade (See 44260 in Figure 24) of the device 44201. [ Alternatively, at the time of connection of the display device 44100 and the second upgrade device 44202, the subject updating the setting information previously stored in the second upgrade device 44202 with the setting information backed up and stored in the external device 44310, And the second control unit (see 44260 in Fig. 24) of the upgrading apparatus 44202. [

24) of the first upgrading device 44201 and the second upgrading device 44202 does not mean the same configuration, but the second controlling part 44260 of FIG. Means that the configuration corresponding to the first upgrading device 44201 and the second upgrading device 44202 are provided in the first upgrading device 44201 and the second upgrading device 44202, respectively.

On the other hand, the operation of backing up the setting information to the external device 44310 at the time of connection of the first upgrading device 44201 and the display device 44100 is performed in real time in response to the change of the setting information, Can be performed at the time of occurrence.

Hereinafter, a method of backing up and storing the setting information in the external device 44310 in real time in accordance with the change of the setting information when the first upgrading device 44201 and the display device 44100 are connected will be described with reference to FIG. 26 do. FIG. 26 is a control flowchart showing this process, and sets a state in which there is no setting information backup-stored in the external device 44310 as an initial state.

26, the first upgrading device 44201 is connected to the display device 44100 in accordance with the connection of the first upgrading device 44201 to the display device 44100 (S44100) An upgrade is performed (S44110).

If the setting information is changed during the upgrade (S44120), the display device 44100 stores the changed setting information in the first upgrading device 44201 (S44130). In step S44140, the display device 44100 backs up the changed setting information, that is, the setting information stored in the first upgrading device 44201, to the external device 44310 at this time.

On the other hand, a method of backing up and storing setting information according to a specific event when the first upgrading device 44201 and the display device 44100 are connected will be described with reference to FIG. FIG. 27 is a control flowchart showing this process, and the state progressing to the step S44110 of FIG. 26 is set as an initial state.

As shown in FIG. 27, when the setting information is changed during the upgrade by the first upgrading device 44201 (S44200), the display device 44100 stores the changed setting information in the first upgrading device 44201 ( S44210). Then, the display device 44100 stores the information change flag information indicating that the setting information has been changed, that is, the change history for the setting information, in the display device 44100 (S44220).

When an event for turning off the system power is generated from a specific event, for example, the user input unit 44140 (S44230), the display apparatus 44100 determines whether the information change flag information is stored (S44240).

If the information change flag information is stored, the display device 44100 backs up the setting information of the first upgrading device 44201 to the external device 44310 (S44250). When the backup storage is completed, the display device 44100 deletes the self-stored information change flag information (S44260) and turns off the system power (S44270).

On the other hand, if the information change flag information is not stored, the display device 44100 turns off the system power (S44270).

According to this process, the display device 44100 can back up the setting information stored in the first upgrading device 44201 in the external device 44310.

Here, if the backup information of the setting information for the external device 44310 is stored through the method shown in FIGS. 26 and 27, the setting information is backed up in the external device 44310 by the display device 44100 In the first storage unit 44150 of the display device 44100. [0199] FIG.

The time at which the backup flag information is stored is not limited. For example, immediately after the setting information is backed up to the external device 44310 in step S44140 of FIG. 26 or before the system power is turned off in step S44270 of FIG. 27 . The backup flag information indicates that the setting information is backup stored in the external device 44310, and includes the address information on the communication of the external device 44310 in which the setting information is backed up.

Such communication address information may be, for example, the URL information of the setting information backed up in the server when the external device 44310 is implemented as a server.

As the setting information related to the first upgrading device 44201 is backed up to the external device 44310 connected to the display device 44100 and the second upgrading device 44202 is connected to the display device 44100 The manner in which the upgrade is performed is described below with reference to FIG. 28 is a control flowchart showing this process.

28, when the second upgrading device 44202 is connected to the display device 44100 (S44300), the display device 44100 displays the second upgrade device 44202 to which the connected second upgrading device 44202 is connected, (S44310).

Here, the previous stage is a stage in which the upgrading apparatus is connected immediately before the second upgrading apparatus 44202 is connected in the step S44300, that is, the first upgrading apparatus 44201 and the display apparatus 44100 in the case of this embodiment, Is connected and the upgrade is performed.

The first upgrading device 44201 and the second upgrading device 44202 each include identification information. Upon connection of the first upgrading device 44201, the display device 44100 acquires the identification information from the first upgrading device 44201 and stores it. In step S44310, the display device 44100 compares the previously stored identification information of the first upgrading device 44201 with the identification information of the newly acquired second upgrading device 44202. In step S44300, It is possible to determine whether the first upgrading apparatus 44201 is connected to the first upgrading apparatus 44201 or the second upgrading apparatus 44202 is connected.

Alternatively, when the operation main body in step S44310 is the second upgrade device 44202, the second upgrade device 44202 acquires the identification information of the display device 44100 as opposed to the above case. The first upgrading device 44201 or the second upgrading device 44202 acquires and stores the identification information of the display device 44100 when the display device 44100 is connected to the display device 44100, By comparing the information with the previously stored identification information, it is possible to determine whether or not the display device 44100 is a previously connected display device 44100 or not.

If the display device 44100 determines that the newly connected second upgrading device 44202 is different from the previously connected first upgrading device 44201, the display device 44100 determines whether there is backup flag information in the display device 44100 (S44320). The backup flag information is information indicating that the setting information is backup-stored in the external device 44310 as described above.

If the display device 44100 determines that there is backup flag information, the display device 44100 connects to the external device 44310 and updates the setting information of the second upgrade device 44202 based on the backup stored setting information of the external device 44310 (S44330) . The access to the backup stored setting information of the external device 44310 is performed through a communication address path included in the backup flag information.

When the update is completed, the display device 44100 controls to perform upgrade by the second upgrading device 44202 based on the updated setting information (S44340).

On the other hand, if it is determined in step S44310 that the second upgrading device 44202 is a device that was connected in the previous step, the display device 44100 controls the second upgrading device 44202 to perform upgrade with the preset information pre- (S44350).

On the other hand, if the display device 44100 judges that there is no backup flag information in step S44320, the display device 44100 controls the upgrade by the second upgrading device 44202 to be performed based on the previously stored setting information (S44360). The display device 44100 may cause the external device 44310 to back-up the setting information previously stored in the display device 44100. [

On the other hand, in step S44310, the display device 44100 can additionally determine whether the second upgrading device 44202 is not a product that is formally manufactured, or whether there is a problem in compatibility with the display device 44100.
