It may also be performed when displaying on the display unit 180.

The demultiplexer 210 may demultiplex the received stream signal TS1 or TS2 into a video signal, an audio signal, and a data signal. Among the separated signals, an image signal may be transmitted to the video decoder 215, and other audio and data signals may be transmitted to the stream encoder 240.

The video decoder 215 extracts and decodes a picture from an input video signal. The extracted picture may be an I picture of the video signal or pictures corresponding to a portion of the video signal. Decoding may be performed by an MPEG 2, MPEG-4 or H.264 decoder or the like. The DV decoder 217 receives the digital signal DV converted by the DV encoder 140 and extracts a picture or pictures of a partial section.

The thumbnail generator 250 generates a thumbnail by scaling and compressing pictures input from the video decoder 215 or the DV decoder 217.

The scaler 220 of the thumbnail generator 250 adjusts the data amount by scaling the video signal input from the video decoder 215 or the DV decoder 217. For example, the size or resolution of an input video signal may be converted. When the size conversion is displayed in the form of a thumbnail on the display unit 180, it is performed to display the appropriate size.

Meanwhile, the scaler 220 may convert the input pictures into different sizes according to the simple view of the "broadcast channel list" and the entire view of the "broadcast channel list." For example, the size of the image shown in thumbnail form in the entire view of the "image channel list" may be larger than the simple view of the "image channel list".

The simple view and full view function may be performed even when the external input list is displayed on the display unit 180 in addition to the channel list. In addition, the channel list and the external input list may be displayed together on the display unit 180.

The image compressor 230 encodes and compresses the image signal converted by the scaler 220. For example, an image size-converted by the scaler 220 may be encoded in JPEG or MPEG-2. The still image or video encoded by the image compressor 230 may be displayed in the form of a thumbnail on the display unit 180 in the future.

The stream encoder 240 packages and multiplexes the video and audio signals from the demultiplexer 210 encoded by the image compressor 230 in the form of transport streams. The packaged transport stream may have the same form as the transport streams TS1 and TS2 input to the channel browsing processor 170-1 or MPEG2 TS form.

Meanwhile, the content display method as described above may be performed by the 3D image display device. That is, the plurality of contents as described above with reference to FIGS. 1 to 19, for example, images of the plurality of broadcast channels may be displayed on the screen as 3D images.

The term 3D is used to describe a visual expression or display technique that attempts to reproduce a three-dimensional video having an optical illusion of depth. For the image of the left eye and the image of the right eye, the observer's visual cortex interprets the two images into one three-dimensional image.

The three-dimensional (3D) display technology may employ the technology of 3D image processing and representation for the device capable of 3D image display. Optionally, a device capable of displaying 3D images may require the use of a special viewing device to effectively provide the viewer with three-dimensional images.

Examples of 3D image processing and representation include stereoscopic image / video capture, multi-view image / video capture using multiple cameras, and processing of two-dimensional image and depth information. Examples of display devices capable of displaying 3D images include liquid crystal displays (LCDs), digital TV screens, and computer monitors having appropriate hardware and / or software supporting 3D display technology. Examples of special observation devices include specialized glasses, goggles, headgear, eyewear, and the like.

Specifically, 3D image display technology includes anaglyph stereoscopic images (commonly used with passive red blue glasses), polarized stereoscopic images (commonly used with passive polarized glasses), and alternating-frame sequencing. (Typically used with active shutter eyeglasses / headgear), Autostereoscopic Displays using Lenticular or Barrier screens.

As an embodiment of the present invention, the 3D image display technology may use an optical device that rotates or alternately operates, for example, a segmented polarizer attached to a color filter wheel, in which case they are synchronized with each other. Is required. Another 3D image display technology is a digital light processor based on a Digital Micromirror Device (DMD) using a rotatable Microscopic Mirror, arranged in a rectangular array corresponding to the pixels of the image to be displayed. Digital Light Processor (DLP) can be used.

On the other hand, new types of standards related to the rendering and display technology of stereoscopic images (particularly 3D TVs) are currently being developed by various companies, consortiums and organizations, such as The Society Of Motion Picture And Television Engineers (CEA), Consumer Electronics Association (CEA), 3d @ Home Consortium, and International Telecommunication Union (ITU). In addition, other standardization groups such as DVB, BDA, ARIB, ATSC, DVD Forum, IEC, etc. are participating. Moving Picture Experts Group (MPEG) is involved in 3D video coding of multidimensional video, stereoscopic video, and two-dimensional video with depth information, and is now multiview video coding for MPEG-4 Advanced Video Coding (AVC). The Multiview Video Coding Extension is being standardized. Stereoscopic image coding and stereoscopic distribution formatting include color shifting, pixel sub-sampling (side-by-side, checkerboard, and quincunx). ), And Enhanced Video Coding (2D + Delta, 2D + Metadata, 2D with Depth Information).

Meanwhile, a conventional 2D display generates only one image. On the other hand, in the 3D image display device, one 3D image may be made of a left image and a right image.

In order to display 3D images, left and right images are alternately displayed on a screen, such as a frame by frame, a side by side, and a top-down. .

The frame division method is a method in which the left image and the right image are alternately scanned on the entire screen. The frame-by-frame division method is also called a frame sequential method, and the left and right screens are alternately displayed, and the original maximum resolution of the display device can be used. This characteristic is called full resolution.

The left and right division method divides a screen from side to side and scans a left image and a right image on the screen. In addition, the vertical division method divides a screen vertically and scans a left image and a right image on the screen.

In addition, the above-described content display method according to the present invention can be stored in a computer-readable recording medium produced as a program for execution on a computer, examples of the computer-readable recording medium are ROM, RAM, CD- ROMs, magnetic tapes, floppy disks, optical data storage, and the like, and also include those implemented in the form of carrier waves (eg, transmission over the Internet).

The computer readable recording medium can be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. In addition, functional programs, codes, and code segments for implementing the broadcast reception method may be easily inferred by programmers in the art to which the present invention belongs.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
