The control unit 170 includes a demultiplexing unit 310, an image processing unit 320, a processor 330, an OSD generating unit 340, a mixer 345, A frame rate conversion unit 350, and a formatter 360. [0031] An audio processing unit (not shown), and a data processing unit (not shown).

The demultiplexer 310 demultiplexes the input stream. For example, when an MPEG-2 TS is input, it can be demultiplexed into video, audio, and data signals, respectively. The stream signal input to the demultiplexer 310 may be a stream signal output from the tuner 110 or the demodulator 120 or the external device interface 130.

The image processing unit 320 may perform image processing of the demultiplexed image signal. For this, the image processing unit 320 may include a video decoder 325 and a scaler 335.

The video decoder 325 decodes the demultiplexed video signal and the scaler 335 performs scaling so that the resolution of the decoded video signal can be output from the display 180.

The video decoder 325 can include a decoder of various standards. For example, a 3D image decoder for MPEG-2, H, and H.264 decoders, a color image and a depth image, and a decoder for a multi-view image may be provided.

The processor 330 may control the overall operation in the image display apparatus 100 or in the control unit 170. [ For example, the processor 330 may control the tuner 110 to select a channel selected by the user or an RF broadcast corresponding to a previously stored channel.

In addition, the processor 330 may control the image display apparatus 100 by a user command or an internal program input through the user input interface unit 150. [

The processor 330 may control operations of the demultiplexing unit 310, the image processing unit 320, the OSD generating unit 340, and the like in the controller 170.

The OSD generation unit 340 generates an OSD signal according to a user input or by itself. For example, based on a user input signal, a signal for displaying various information in a graphic or text form on the screen of the display 180 can be generated. The generated OSD signal may include various data such as a user interface screen of the video display device 100, various menu screens, a widget, and an icon. In addition, the generated OSD signal may include a 2D object or a 3D object.

The OSD generating unit 340 can generate a pointer that can be displayed on the display based on the pointing signal input from the remote control device 200.

Of course, a pointing signal processing unit (not shown) may be provided separately from the OSD generating unit 240.

The mixer 345 may mix the OSD signal generated by the OSD generator 340 and the decoded video signal processed by the image processor 320. The mixed video signal is supplied to a frame rate converter 350.

A frame rate converter (FRC) 350 can convert the frame rate of an input image. On the other hand, the frame rate converter 350 can output the frame rate without conversion.

The formatter 360 may arrange the left eye image frame and the right eye image frame of the frame rate-converted 3D image. Then, the left eye glass of the 3D viewing apparatus (not shown) and the synchronization signal Vsync for opening the right eye glass can be output.

On the other hand, the formatter 360 may convert the format of the input video signal into a video signal for display on a display and output the video signal.

In addition, the formatter 360 can change the format of the 3D video signal. For example, in various 3D formats such as Side by Side, Top / Down, Frame Sequential, Interlaced, and Checker Box formats, It can be changed to any one format.

Meanwhile, the formatter 360 may convert the 2D video signal into a 3D video signal. For example, according to a 3D image generation algorithm, an edge or a selectable object is detected in a 2D image signal, and an object or a selectable object according to the detected edge is separated into a 3D image signal and is generated . At this time, the generated 3D image signal can be separated into the left eye image signal L and the right eye image signal R, as described above.

Although not shown in the drawing, it is also possible that a 3D processor (not shown) for 3-dimensional effect signal processing is further disposed after the formatter 360. The 3D processor (not shown) can process the brightness, tint, and color of the image signal to improve the 3D effect. For example, it is possible to perform signal processing such as making the near field clear and the far field blurring. On the other hand, the functions of such a 3D processor can be merged into the formatter 360 or merged into the image processing unit 320. [

Meanwhile, the audio processing unit (not shown) in the control unit 170 can perform the audio processing of the demultiplexed audio signal. To this end, the audio processing unit (not shown) may include various decoders.

In addition, the audio processing unit (not shown) in the control unit 170 can process a base, a treble, a volume control, and the like.

The data processing unit (not shown) in the control unit 170 can perform data processing of the demultiplexed data signal. For example, if the demultiplexed data signal is a coded data signal, it can be decoded. The encoded data signal may be electronic program guide information including broadcast information such as a start time and an end time of a broadcast program broadcasted on each channel.

Meanwhile, the block diagram of the controller 170 shown in FIG. 3 is a block diagram for an embodiment of the present invention. Each component of the block diagram can be integrated, added, or omitted according to the specifications of the control unit 170 actually implemented.

In particular, the frame rate converting unit 350 and the formatter 360 are not provided in the controller 170, and may be separately provided, or may be separately provided as one module.

4C illustrates a case in which the user moves the remote control device 200 away from the display 180 while pressing a specific button in the remote control device 200. [ Thereby, the selected area in the display 180 corresponding to the pointer 205 can be zoomed in and displayed. Conversely, when the user moves the remote control device 200 close to the display 180, the selection area within the display 180 corresponding to the pointer 205 may be zoomed out and zoomed out. On the other hand, when the remote control device 200 moves away from the display 180, the selection area is zoomed out, and when the remote control device 200 approaches the display 180, the selection area may be zoomed in.

On the other hand, when the specific button in the remote control device 200 is pressed, it is possible to exclude recognizing the up, down, left, and right movement. That is, when the remote control apparatus 200 moves away from or approaches the display 180, it is not recognized that the up, down, left, and right movements are recognized, and only the forward and backward movements are recognized. Only the pointer 205 is moved in accordance with the upward, downward, leftward, and rightward movement of the remote control device 200 in a state where the specific button in the remote control device 200 is not pressed.

On the other hand, the moving speed and moving direction of the pointer 205 may correspond to the moving speed and moving direction of the remote control device 200.
