Here, the configuration of the signal input unit 505 is the same as that of the signal input unit 111 of FIG. 3, so that the detailed description is omitted.

That is, the display unit 130 according to an exemplary embodiment of the present invention may include a signal input unit 505 to receive the video signal itself and display the received video signal.

The storage unit 478 may be constituted by a program memory and a data memory. The program memory stores an operation program of the display unit 130 and a program for providing a user interface using the touch screen 585. [ The data memory may store a program for each signal processing and control in the controller 480, and may store signal processed video, audio, or data signals.

The data memory of the storage unit 478 may include a multimedia storage area 543 for storing one or more multimedia files (audio files, moving picture files, etc.), and a playback information (volume information, tone color information, And a reproduction control information storage area 545 for storing the reproduction control information.

The configuration of the signal processing unit will be described in detail in Fig. 6 below.

The audio processing unit 560 converts the audio signal processed by the control unit 480 into a format that can be output by the audio output unit 495 and outputs the format. And may encode a voice signal input through a microphone (not shown) and output the encoded voice signal to the control unit 480 or the storage unit 478.

Lt; RTI ID = 0.0 > 589 < / RTI > The display panel 583 may be implemented as a display device such as an LCD, a PDP, and an OLED.

The touch sensing unit 587 senses a change in the physical quantity (resistance, capacitance, etc.) corresponding to the input event (touch event) according to the touch of the user and detects the occurrence of the input event. Then, the touch sensing unit 587 transmits the physical quantity of the sensed input event to the signal processor 589.

Here, the input event is a touch operation or the like, which is an operation of the user, is input to the touch screen 585. [ The signal processing unit 589 converts a change in physical quantity according to an input event into a digital signal. The signal processor 589 determines whether the input event caused by the change of the physical quantity is a touch event or a drag event. The signal processing unit 589 measures the coordinates of the input event sensed by the touch sensing unit 587 and outputs it to the control unit 480.

When the touch screen 585 is included in the display unit 130, the user can directly input a predetermined command to the display unit 130 without using the remote controller 200 using the touch screen 585. Accordingly, the user can control the video display device 100 more conveniently.

FIG. 6 is a block diagram illustrating the control unit of FIG. 5 in detail. Specifically, it is a block diagram showing the control unit 330 (specifically, the signal processing unit 340) in FIG. 3 and the control unit 480 in FIG. 4 and FIG.

The demultiplexer 31 demultiplexes the input stream. For example, when an MPEG-2 TS is input, it can be demultiplexed into video, audio, and data signals, respectively. Here, the stream signal input to the demultiplexer 31 may be a stream signal according to the AV signal.

The image processing unit 32 can perform image processing of the demultiplexed image signal. To this end, the image processing unit 32 may include a video decoder 33 and a scaler 34. [

The video decoder 33 decodes the demultiplexed video signal and the scaler 34 performs scaling so that the resolution of the decoded video signal can be output from the display panel 583.

The video decoder 33 can be provided with a decoder of various standards.

For example, if the demultiplexed video signal is an MPEG-2 standard encoded video signal, it can be decoded by an MPEG-2 decoder.

Also, for example, if the demultiplexed video signal is an encoded video signal of the H.264 standard according to the DMB (Digital Multimedia Broadcasting) scheme or DVB-H, it can be decoded by the H.264 decoder.

On the other hand, the video signal decoded by the video processor 32 is input to the mixer 35.

The OSD generation unit 38 generates an OSD signal according to a user input or by itself. For example, based on a user input signal or a control signal, a signal for displaying various information in graphic or text on the screen of the display panel 583 can be generated. The generated OSD signal may include various data such as a user interface screen of the display unit 130, various menu screens, a widget, and an icon.

For example, the OSD generating unit 38 may generate a signal for displaying broadcast information based on a caption of a broadcast image or an EPG.

The mixer 35 may mix the OSD signal generated by the OSD generator 38 and the decoded video signal processed by the image processor 32. The mixed signal is provided to the formatter 37. Since the decoded broadcast video signal or the external input signal and the OSD signal are mixed, the OSD can be overlaid on the broadcast image or the external input image.

A frame rate converter (FRC) 36 can convert the frame rate of an input image. For example, a frame rate of 60 Hz is converted to 120 Hz or 240 Hz. When converting the frame rate of 60 Hz to 120 Hz, it is possible to insert the same first frame between the first frame and the second frame, or insert the third frame predicted from the first frame and the second frame. When converting a frame rate of 60 Hz to 240 Hz, it is possible to insert three more identical frames or insert three predicted frames. On the other hand, it is also possible to maintain the input frame rate without performing another conversion.

The formatter 37 receives the output signal of the frame rate conversion unit 36, changes the format of the signal to be suitable for the display panel 583, and outputs the signal. For example, the R, G, and B data signals may be output as low voltage differential signaling (LVDS) signals or mini-LVDS signals.
