Stereoscopic picture coding and stereo-scoped distribution formatting includes color shifting (Anaglyph), pixel sub-sampling (Side-By-Side, Checkerboard, Quincunx) , And Enhanced Video Coding (2D + Delta, 2D + Metadata, 2D with depth information).

On the other hand, in the conventional 2D image display device (2D display), only one image is produced. On the other hand, in the 3D image display device, one 3D image can be formed from the left image and the right image.

There are frame-by-frame, side-by-side, and top-down schemes in which left and right images are alternately displayed on the screen for realizing a 3D image .

The frame-by-frame division method is a method in which a left image and a right image are alternately scanned on the entire screen. The frame-by-frame division method is also referred to as a frame sequential method, and the original maximum resolution of the bar display device which alternately displays the left screen and the right screen can be used. Such a characteristic is referred to as a full resolution.

The left and right division method divides the screen into left and right images, and the left and right images are respectively scanned on the screen. The upper and lower division method is a method in which a left image and a right image are scanned on the screen by dividing the screen up and down.

The computer readable recording medium may be a ROM, a RAM, a CD- ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may also be implemented in the form of a carrier wave (for example, transmission over the Internet).

The computer readable recording medium may be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner. And, functional programs, codes, and code segments for implementing the broadcast receiving method can be easily inferred by programmers of the technical field to which the present invention belongs.
