Provided are a multi-display supporting multi-view video object-based encoding apparatus and method, and an object-based transmission/reception system and method using the encoding apparatus and method. The encoding apparatus includes: a shape abstracting means for receiving right/left-eye image object video and abstracting right/ left object image, respectively, to abstract the shape information of a multi-view video; a data separating means for receiving the right/left-eye image object video, and the right/left shape information, and separating them into odd-field objects and even field objects to transmit only the essential bit streams for a user display mode; a shape compensation means for compensating for the distortion of the shape information separated into odd and even fields; and an object-based encoding means for receiving the object-based information from the shape compensation means and the object-based information from the data separating means, forming four layers, and performing motion and disparity estimation to encode object-based data that are separated into odd and even lines.

Disclosed is a stereoscopic/multiview three-dimensional video processing system and its method. In the present invention, stereoscopic/multiview three-dimensional video data having a plurality of images at the same time are coded into a plurality of elementary streams. The plural elementary streams output at the same time are multiplexed according to the user's selected display mode to generate a single elementary stream. After packetization of the single elementary stream continuously generated, information about the stereoscopic/multiview three-dimensional video multiplexing method and the selected display mode information are added to the packet header of the stream. Then the packetized elementary stream is sent to the image reproducer or stored in storage media. The present invention multiplexes the multi-channel elementary streams having the same temporal and spatial information, thereby minimizing the overlapping header information, and performs streaming of data suitable for the user's demand and the user system environments.

A data processing system and method for stereoscopic 3D video based on MPEG-4. Various elementary streams of left and right images of stereoscopic 3D video are multiplexed into a single stream, and efficient buffer management is performed through field encoding that supports possible display methods. The system minimizes the synchronization time of left and right images and reduces the complexity of the decoder model. Also, a decoding buffer size is allocated to enable support of stereoscopic 3D video field/frame shuttering and stereoscopic 3D video polarized display, while maintaining compatibility with conventional 2D video data processing. Finally, only DTS and CTS are transmitted at the same time, and DTS and CTS of the remaining times are estimated to thereby simplify synchronization.
