FIG. 4 is an internal block diagram of the control unit of FIG. 2. FIG.

The control unit 170 includes a demultiplexing unit 310, an image processing unit 320, an OSD generating unit 340, a mixer 350, a frame rate converting unit 355 ), And a formatter 360. A voice 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 135.

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 unit 180.

The video decoder 325 can include 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.

Meanwhile, the video signal decoded by the video processor 320 is input to the mixer 350.

The OSD generation unit 340 generates an OSD signal according to a user input or by itself. For example, based on a control signal from the user input interface unit 150, a signal for displaying various kinds of information in a graphic or text format can be generated on the screen of the display unit 180. 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.

For example, the OSD generating unit 340 may generate a signal for displaying broadcast information based on a caption of a broadcast image or an EPG.

The mixer 350 may mix the OSD signal generated by the OSD generator 340 and the decoded video signal processed by the image processor 220. The mixed signal is provided to formatter 360. 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) 355 can convert a 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 360 receives the output signal of the frame rate conversion unit 355 and changes the format of the signal to be suitable for the display unit 180 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.

On the other hand, 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 voice processing unit (not shown) may include various decoders.

When a demultiplexed speech signal is a coded speech signal, the speech processing unit (not shown) in the control unit 170 can decode the demultiplexed speech signal. For example, the demultiplexed speech signal may be decoded by an MPEG-2 decoder, an MPEG 4 decoder, an AAC decoder, or an AC-3 decoder.

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 EPG (Electronic Program Guide) information including broadcast information such as a start time and an end time of a broadcast program broadcasted on each channel. For example, the EPG information may be ATSC-PSIP (ATSC-Program and System Information Protocol) information in the case of the ATSC scheme and may include DVB-SI information in the DVB scheme . The ATSC-PSIP information or DVB-SI information may be information included in the above-described stream, i.e., the header (4 bytes) of the MPEG-2 TS.
