The upgrade apparatus 800 includes a main body connecting portion 810 connectable to the display apparatus 800; A second image processor 820 for receiving and processing a signal output from the display apparatus 700 through the main body connecting unit 810; And a second controller 830 for controlling the second image processor 820.

Here, when the second image processor 820 is provided to be controlled only by the first controller 740 of the display apparatus 700, the second controller 830 may be omitted as necessary.

The second image processor 820 is any one of the input signal of the first image signal input unit 710 output from the display apparatus 700 and the first output signal output from the first image processor 730. Process to output the second output signal.

The second output signal output by the second image processor 820 is transmitted to the display unit 770 through the main body connecting unit 810 and the upgrade apparatus connecting unit 760. As a result, a second image corresponding to the second output signal may be displayed on the display unit 770. The second image processing unit 820 may further deepen the function of the first image processing unit 730 or may additionally perform a function that may not be performed by the first image processing unit 730. An upgraded image that may not be implemented or difficult to implement with the existing display apparatus 700 may be displayed.

For example, the first image processor 730 may not provide a Full HD image, but the second image processor 820 may provide a Full HD image. In addition, the 3D screen may be implemented through the second image processor 820 that the 3D screen may not be provided to the first image processor 730. Of course, these additional and expanded functions are only examples and can be variously changed.

Here, the second image processor 820 may reprocess the audio signal in addition to the video signal, and thus the audio signal upgraded and reprocessed may be provided to the display apparatus 700.

Meanwhile, the upgrade apparatus 800 may further include a second image signal input unit 850 which receives a video signal from a broadcast signal or an image supply source and transmits the image signal to the second image processor 820.

In the above description, it has been described that the broadcast signal or the video signal is received or input through the first video signal input unit 710 of the display apparatus 700. However, in some cases, the upgrade apparatus 800 may use the second video signal. A video signal input unit 850 may be provided to receive a broadcast signal or a video signal separately from the display apparatus 700. In this case, when the first control unit 740 of the display apparatus 700 detects that the upgrade apparatus 800 is connected to the upgrade apparatus connection unit 760, the first image signal input unit 710 and The operation of the first image processor 730 may be stopped.

The first image processor 730 may be controlled to process an input signal input through 710 to output a first output signal to the display unit 770. 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 770. At the same time, when the broadcast signal or the video signal received through the second video signal input unit 850 is input, the upgrade apparatus 800 processes the second image processor 820 to process the second output signal. The display unit 770 may transmit the information. Accordingly, the second image corresponding to the second output signal may be displayed as a sub-screen or a main screen on the display unit 770. That is, a first input signal (broadcast signal and / or video signal) input through the first image signal input unit 710 of the display apparatus 700 and the second image signal input unit 850 of the upgrade apparatus 800. The first and second images processed by the second input signal (broadcast signal and / or video signal) input through the may be displayed as picture in picture (PIP) on the display unit 770, respectively.

For example, the first controller 740 is responsible for controlling some of the demultiplexer (not shown), the decoder (not shown), and the scaling unit (not shown) of the first image processor 730. In addition, the second controller 830 may be provided to perform the remaining control.

In some cases, the first control unit 740 has the authority to control the first image signal input unit 710 and the first image processing unit 730 first, and the second control unit 830 gives the first control. It may be provided to assist the control unit 740.

In some cases, on the contrary, the second control unit 830 has the authority to control the first image signal input unit 710 and the first image processing unit 730 first, and the first control unit 740 controls the first image. It may be provided to assist the second control unit 830.

Meanwhile, when it is detected that the upgrade apparatus 800 is connected, the first controller 740 of the display apparatus 700 controls the control function of the first controller 740 to the second controller 830. You can also migrate completely to. In this case, the first control unit 740 does not issue a control command, and performs only a function of transmitting a control command between the control objects controlled by the existing first control unit 740 and the second control unit 830. It may be. In some cases, a dedicated control communication line for transmitting and receiving a control command between the second control unit 830 and the control target controlled by the existing first control unit 740 may be separately provided.

The upgrade apparatus 800 may further include a second storage unit 840.

Unlimited data may be stored in the second storage unit 840.

The second storage unit 840 may be implemented as a nonvolatile memory such as a flash memory and a hard disk drive. The second storage unit 840 is accessed by the first control unit 740 or the second control unit 830, and data read / write / modify / delete / update are performed by the second control unit 740. Meanwhile, the first storage unit 797 may also be accessed by the second control unit 830 as well as the first control unit 740 depending on the implementation manner.

In addition, the second storage unit 840 may store an operating system upgraded from an operating system stored in the first storage unit 797, and the first control unit 740 or the second control unit 830 may store the first operating system. The operating system stored in the first storage unit 797 may be updated with the upgraded operating system, and the updated operating system may be driven. In some cases, the operating system of the second storage unit 840 may be driven instead of the operating system stored in the first storage unit 797.
