Abstract: Provided is a steroscopic video encoding and/or decoding apparatus that supports multi-display modes, the encoding/decoding method thereof, and computer-readable recording medium for recording a program that implements the encoding/decoding method. The encoding apparatus of this research incorporates: a field separating means for separating right and left-eye input images into an odd field of the left-eye image (LO), even field of the left-eye image (LE), odd-numbered field (RO) of the right-eye image, and even-numbered field (RE) of the right-eye image; an encoding means for encoding the fields separated in the field separating means by performing motion and disparity compensation; and a multiplexing means for multiplexing the essential fields among the fields received from the encoding means, based on the user display information.

Abstract: Provide is a 3-dimensional Digital Multimedia Broadcasting (3D DMB) system. The present invention can provide a 3D DMB system providing a more realistic 3D Audio/Video (AV) service to a user, while maintaining comparability with a conventional DMB system, by processing a binocular 3D image and 3D sound based on a conventional system structure. The 3D DMB system includes: a video encoder for receiving and encoding a video signal of a binocular 3D image; an audio encoder for receiving and encoding an audio signal of a 3D sound; a packetizor for packetizing the encoded video and audio signals into an Sync Layer (SL) packet; and a multiplexer for transforming and multiplexing the SL packet packetized by the packetizer. A 3D DMB receiving system includes: a demultiplexer for demultiplexing a stream including binocular 3D image information and 3D sound information; a depacketizer for depacketizing the SL packet and outputting a decoding stream of an 3D video signal and a 3D sound audio signal; a video decoder for decoding a encoding stream for a video signal of the binocular 3D image; an audio decoder for decoding a encoding stream for the 3D sound audio signal; and a scene restorer for forming and outputting a 2D AV or 3D AV scene by using a video/3D additional video and an audio/3D additional audio signal which are received from the video decoder and the audio decoder.
