3, the OSD (On Screen Display) generating unit 108 includes a lock function selection area 304 and an external operation button setting area 306 corresponding to a sequential selection of each external operation button The setup menu screen 302 can be output through the display device.

The display device converts a video signal processed by the video signal processor 110 and an OSD signal generated by the OSD generator 108 into R, G, and B signals, respectively, to generate a driving signal. The display device can be implemented in various forms such as a PDP, an LCD, an OLED, a flexible display, and a 3D display. Further, the display device may be constituted by a touch screen and used as an input device in addition to the output device.

The display unit 112 may display a current operation state or a selected channel of the image processing apparatus of the present invention, and may display a lock function status message when the lock function is set.

The image signal processing unit 110 may perform image processing of the demultiplexed image signal. For example, if the demultiplexed video signal is a coded video signal, it can be decoded. Specifically, when the demultiplexed video signal is an MPEG-2 standard-coded video signal, it can be decoded by an MPEG-2 decoder. Also, if the demultiplexed video signal is a 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.

When the image processing apparatus according to another embodiment of the present invention is a television, the image processing apparatus may include a tuner (not shown), a demodulator (not shown), and an external signal input unit (not shown). The tuner selects an RF broadcast signal corresponding to a channel selected by the user from an RF (Radio Frequency) broadcast signal received through an antenna, and converts the selected RF broadcast signal into an intermediate frequency signal or a baseband video / audio signal. For example, if the selected RF broadcast signal is a digital broadcast signal, the signal is converted into a digital IF signal. If the selected RF broadcast signal is an analog broadcast signal, the signal is converted into an analog baseband video / audio signal. That is, the tuner may be a hybrid tuner capable of processing a digital broadcast signal and an analog broadcast signal.

A demodulator (not shown) receives the digital IF signal converted by the tuner and performs a demodulation operation. For example, if the digital IF signal output from the tuner is of the ATSC scheme, the demodulator can perform 8-VSB (8-Vestigal Side Band) demodulation.

An external signal input unit (not shown) performs signal input with an external device. To this end, an external signal input unit (not shown) may include an A / V input / output unit and a wireless communication unit. The external signal input unit is connected to an external device such as a DVD (Digital Versatile Disk), a Blu ray, a game device, a camcorder, a computer (notebook computer), etc. to output an external input video signal, Signal to the image processing apparatus.

Meanwhile, the external signal input unit (not shown) may be connected to various set-top boxes to perform input / output operations with the set-top boxes.

For example, when the set-top box is a set-top box for an IP (Internet Protocol) TV, the video, audio and data signals processed by the settop box for IPTV can be transmitted to the controller so that bidirectional communication is possible. Lt; RTI ID = 0.0 > IPTV set-top box. ≪ / RTI >

Meanwhile, the IPTV may include ADSL-TV, VDSL-TV, FTTH-TV and the like depending on the type of the transmission network. The IPTV may include a TV over DSL, a video over DSL, a TV over IP BTV), and the like. In addition, IPTV may also mean an Internet TV capable of accessing the Internet, or a full browsing TV.
