  • Patent number: 7136415
    Abstract: An apparatus and method for multiplexing a multi-view three-dimensional moving picture according to a user's request is disclosed. The apparatus multiplexes a multi-view three-dimensional moving pictures by receiving moving pictures and information inputted from multi-view cameras and generating multi-view encoded streams corresponding to received moving pictures and information, receiving back channel information of the user, selecting necessary multi-view encoded streams according to the back channel information and multiplexing the selected multi-view encoded streams by a frame or a field having same time information. The present invention can effectively process the multi-view three-dimensional moving picture according to the display mode and system environment requested from the user by simplifying a synchronization process.

  • Publication number: 20060133493
    Abstract: Stereoscopic video is encoded and decoded by using the MAC defined by the existing MPEG-4 standard. The stereoscopic video is divided into one image as a single video object, and another image as auxiliary information for the image established as the video object. The auxiliary information includes a horizontal disparity map, a vertical disparity map, luminance residual texture, and chrominance residual texture, which are respectively allocated to auxiliary components of the MAC according to importance and complexity of the images, encoded, and then output as a single encoding stream.

  • Publication number: 20030095177
    Abstract: 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.
