For example, if the demultiplexed speech signal is a coded speech signal, it can be decoded. Specifically, when the demultiplexed speech signal is an encoded speech signal of MPEG-2 standard, it may be decoded by an MPEG-2 decoder. In addition, when the demultiplexed speech signal is an encoded speech signal of MPEG 4 Bit Sliced Arithmetic Coding (BSAC) standard according to the terrestrial digital multimedia broadcasting (DMB) scheme, it may be decoded by an MPEG 4 decoder. In addition, when the demultiplexed speech signal is an encoded audio signal of the AAC (Advanced Audio Codec) standard of MPEG 2 according to the satellite DMB scheme or DVB-H, it may be decoded by the AAC decoder. In addition, when the demultiplexed speech signal is a encoded speech signal of the Dolby AC-3 standard, it may be decoded by the AC-3 decoder.

Also, the audio processor 230 in the controller 170 may process base, treble, volume control, and the like.

The data processor (not shown) in the controller 170 may perform data processing of the demultiplexed data signal. For example, when the demultiplexed data signal is an encoded data signal, it may be decoded. 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 ATSC-PSIP (ATSC-Program and System Information Protocol) information in the case of the ATSC scheme, and may include DVB-Service Information (DVB-SI) in the case of the DVB scheme. . The ATSC-PSIP information or the DVB-SI information may be information included in the aforementioned stream, that is, the header (2 bytes) of the MPEG-2 TS.

Meanwhile, although FIG. 2 illustrates that the signals from the OSD generator 240 and the image processor 220 are mixed in the mixer 245 and then 3D processed in the formatter 260, the mixer is not limited thereto.

Referring to the drawings, in order to increase the 3D effect, the controller 170 may perform 3D effect signal processing. Among them, in particular, the size or tilt of the 3D object in the 3D image may be adjusted.

As shown in FIG. 5A, the 3D video signal or the 3D object 510 in the 3D video signal may be enlarged or reduced 512 as a whole at a predetermined ratio, and as shown in FIGS. 5B and 5C. The 3D object may be partially enlarged or reduced (trapezoidal shapes 514 and 516). In addition, as shown in FIG. 5D, at least a part of the 3D object may be rotated (parallel quadrilateral shape) 518. Through such scaling (scaling) or tilting, it is possible to emphasize a three-dimensional effect, that is, a three-dimensional effect, of a 3D image or a 3D object in the 3D image.

On the other hand, as the slope becomes larger, as shown in FIG. 5 (b) or FIG. 5 (c), the length difference between the parallel sides of the trapezoidal shapes 514 and 516 increases, or as shown in FIG. It gets bigger.

Meanwhile, the size adjustment or the tilt adjustment may be performed after the 3D video signal is aligned in a predetermined format in the formatter 260. Alternatively, the image may be performed by the scaler 235 in the image processor 220. On the other hand, the OSD generation unit 240, it is also possible to generate the object in the shape as shown in Figure 5 to generate the OSD to emphasize the 3D effect.

On the other hand, although not shown in the figure, as a signal processing for the 3-dimensional effect, in addition to the size adjustment or tilt adjustment illustrated in FIG. 5, the brightness, tint and It is also possible to perform signal processing such as color adjustment. For example, signal processing may be performed to sharpen the near distance and blur the far distance. Meanwhile, the signal processing for the 3D effect may be performed in the controller 170 or may be performed through a separate 3D processor. In particular, when performed in the controller 170, it may be performed in the formatter 260 or in the image processor 220 together with the above-described size adjustment or tilt adjustment.

In particular, when the display 180 of the image display apparatus 100 is vertically disposed on the ground and horizontally disposed on the ground, 3D in the 3D image or the 3D image according to the embodiment of the present invention.

The interval between the fourth right eye image 643 and the fourth left eye image 641 is set to d4. Here, an inequality of 'd3 <d4' is established between d3 and d4. The user recognizes that an extension line connecting the left eye 601 and the fourth left eye image 641 and the extension line of the right eye 603 and the fourth right eye image 643 intersect. Accordingly, the user recognizes that the fourth object 645 is located in front of the display 180, that is, closer to the user, and closer to the user than the third object 635. That is, the fourth object 645 is recognized by the user as if the fourth object 645 is positioned to protrude toward the user rather than the display 180 and the third object 635. The fourth object 645 has a depth positive value.
