Hereinafter, the display apparatus 100 according to exemplary embodiments of the present invention will be in detail described with reference to FIG. 2.
FIG. 2 is a flowchart illustrating a method of upgrading a control program according to an exemplary embodiment of the present invention.
First, the controller 170 checks whether to connect the portable apparatus 200 to the display apparatus 100 (S101). A user may spontaneously connect the portable apparatus 200 to the display apparatus 100. Alternatively, the user may connect the portable apparatus 200 to the display apparatus 100 because of various reasons.
For example, if an operation error occurs while the display apparatus 100 is operated, the user may think that a control program 141 has a bug and thus the control program 141 is to be upgraded. Alternatively, the user may acquire information related to whether the control program 141 is to be upgraded, through the portable apparatus 200. At this time, the upgrade server 300 corresponds a model name of a purchased display apparatus 100 to a telephone number of a user that purchases the display apparatus 100, and the like, and previously stores the model name and the corresponding telephone number together. Accordingly, when a control program of the upgrade server 300 is upgraded, the upgrade server 300 can inform the user through the portable apparatus 200 that the control program 141 of the purchased display apparatus 100 is to be upgraded through a SMS (Short Message Service), and the like.
As the result of checking it in operation S101, if the portable apparatus 100 is connected to the display apparatus 200, the controller 170 checks whether a user selects a function to upgrade the control program 141 (S102). At this time, the controller 170 may receive a concerned user input through the user input part 103 or from the connected portable apparatus 200.
The controller 170 controls the menu generating part 160 to generate a menu (not shown) related to an upgrade of the control program 141, and displays the generated menu in the display part 150 for a user. For example, it is preferable but not necessary that the generated menu includes a menu item to display “do you want system software to be upgraded?” According to an exemplary implementation, that the generated menu may further include another menu item having a ‘Yes’ sub-item and a ‘No’ sub-item that the user can select to determine whether to upgrade the system software.
As the result of checking it in operation S102, if the user does not select the function to upgrade the control program 141, the controller 170 performs a general function such as an image processing control, and the like depending on a user input (S107).
According to an exemplary implementation, if the user selects the function to upgrade the control program 141, the controller 170 controls the communication part 110 to transmit upgrade information stored in the storing part 140 to the upgrade server 300 through the portable apparatus 200 (S103). The portable apparatus 200 is connected to the upgrade server 300 through a network, and transmits the upgrade information received from the display apparatus 100 to the upgrade server 300. An address of the upgrade server 300 such as an URL (Uniform Resource Locator) may be transmitted from the display apparatus 100 to the portable apparatus 200. At this time, an address of a concerned upgrade server 300 may be preset in the storing part 140 when the display apparatus 100 is manufactured.
Then, if the upgrade server 300 receives the upgrade information from the portable apparatus 100, the upgrade server 300 transmits information related to an upgrade state of the control program 141 and explanation of a corresponding upgrade control program to the portable apparatus 200 with reference to a concerned model name, and so on. Then, if the display apparatus 100 receives the information related to the upgrade state of the control program 141 and the explanation of the upgrade control program from the portable apparatus 200, the controller 170 controls the menu generating part 160 so that the generated menu can include the received information.
Then, the controller 170 checks whether the user determines to upgrade the control program 141 (S104). According to an exemplary implementation, the controller 170 controls the menu generating part 160 so that the generated menu can further include a menu item to determine whether to upgrade the control program 141. As the result of checking it, if the user does not determine to upgrade the control program 141, the controller 170 stops an upgrading operation of the control program 141.
If the user determines to upgrade the control program 141, the controller 170 controls the communication part 110 to transmit a user determination of upgrading the control program 141 to the portable apparatus 200. On the other hand, if the upgrade server 300 receives the user determination through concerned information received from the portable apparatus 200, the upgrade server 300 transmits a new-version of the upgrades control program to the portable computer 200.
Then, the controller 170 controls the communication part 110 to download the new version of the upgrade control program from the portable computer 200 (S105). Then, the controller 170 upgrades the control program 141 by replacing the stored control program with the downloaded new version of the upgrade control program (S106).
On the other hand, in operation S103, the controller 170 may control the communication part 110 to transmit state information and the upgrade information, which are stored in the storing part 140, together to the upgrade server 300. At this time, if the state information and the upgrade information are received from the portable apparatus 200, the upgrade server 300 may recognize the reason why the display apparatus 100 is abnormally operated by analyzing the state information, and transmit resulting information related to the recognized reason to the portable computer 200. For example, if an old lamp equipped in the display apparatus 100 is almost used up, the result information may include a suggestion of replacing the old lamp with a new lamp. At this time, if the result information is received from the portable computer 200, the controller 170 controls the menu generating part 160 so that the result information can be displayed on the display part 150 and thus the user can suitably deal with a problem of the display apparatus 100.
As apparent from the above description, the present invention can develop the convenience of a user and reduce a concerned after-sale service cost when upgrading a concerned control program.
For example, certain embodiments of the present invention can reduce the concerned after-sale service cost by downloading a new control program from a corresponding server through a user's portable apparatus instead of a user's directly visiting an after-sale service center to update a control program.
For example, certain embodiments of the present invention can inexpensively upgrade the control program by using an USB port provided in a general display apparatus and the user's portable apparatus.
In addition, if the display apparatus is abnormally operated, exemplary implementations of the present invention may inform the user of a reason why the display apparatus is abnormally operated so that the user can suitably deal with a problem of the display apparatus.
Certain exemplary embodiments of the present invention can also be embodied as computer-readable codes on a computer-readable recording medium. The computer-readable recording medium is any data storage device that can store data which can thereafter be read by a computer system. Examples of the computer-readable recording medium include, but are not limited to, read-only memory (ROM), random-access memory (RAM), CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, and carrier waves (such as data transmission through the Internet). The computer-readable recording medium can also be distributed over network-coupled computer systems so that the computer-readable code is stored and executed in a distributed fashion. Also, functional programs, codes, and code segments for accomplishing the present invention can be easily construed as within the scope of the invention by programmers skilled in the art to which the present invention pertains. The described hardware devices may be configured to act as one or more software modules in order to perform the operations of the above-described exemplary embodiments of the present invention.
Although exemplary embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the scope of the present invention.
