Convert to a signal. For example, if the selected RF broadcast signal is a digital broadcast signal, it is converted into a digital IF signal DIF1, and if it is an analog broadcast signal, it is converted into an analog baseband video / audio signal CVBS 1 / SIF. That is, the first tuner 120 may be a hybrid tuner capable of processing digital broadcast signals and analog broadcast signals. The analog baseband video / audio signal CVBS 1 / SIF output from the first tuner 120 may be directly input to the controller 160.

Also, as described below, the first tuner 120 receives an RF broadcast signal of a single carrier according to an Advanced Television Systems Committee (ATSC) scheme or an RF broadcast signal of multiple carriers according to a digital video broadcasting (DVB) scheme. It is also possible.

Similar to the first tuner 120, the second tuner 125 selects an RF broadcast signal corresponding to a channel selected by a user from a radio frequency (RF) broadcast signal received through an antenna and selects the selected RF broadcast signal.

In addition, the first demodulator 130 may perform channel decoding. To this end, the first demodulator 130 may include a convolution decoder, a deinterleaver, a reed-soloman decoder, and the like to perform convolutional decoding, deinterleaving, and reed-soloman decoding.

The external signal input unit 128 performs signal input with an external device. To this end, the external signal input unit 128 may include an A / V input / output unit and a wireless communication unit.

The external signal input unit 128 is connected to an external device such as a digital versatile disk (DVD), a Blu-ray, a game device, a camcorder, a computer (laptop), or the like to receive an external input video signal, an external input audio signal, and an external device. The input data signal is transmitted to the controller 160 in the image display apparatus 100. In addition, the video signal, the audio signal, and the data signal processed in the controller 160 may be output to another external device.

The encoded data signal may be EPG (Electronic Progtam Guide) information including broadcast information such as a start time and an end time of a broadcast program broadcasted in each channel. For example, the EPG information may be TSC-PSIP (ATSC-Program and System Information Protocol) information in the ATSC scheme, and may include DVB-Service Information (DVB-SI) in the DVB scheme. . The ATSC-PSIP information or the DVB-SI information may be information included in the aforementioned stream, that is, the header (4 bytes) of the MPEG-2 TS.

The DV decoder 217 receives the digital signals DV1 and DV2 converted by the analog / digital converters 140 and 145 to obtain a digital image.

The format converter 220 converts the format of the video signal input from the picture decoder 215 or the DV decoder 217. For example, the magnitude (resolution) of the input video signal may be converted. Such a size conversion is performed so that the sub-display 183 is shown with a proper size when shown as a plurality of thumbnail images.

The video encoder 230 encodes the video signal converted by the format converter 220. For example, the image size-converted by the format converter 220 may be encoded in JPEG or MPEG-2.
