It is difficult to reduce the amount of encoded information in MPEG2, which is a standard encoding method for motion pictures, because of the information spent by headers and so on. In stereo motion pictures, it is known that if a high-resolution picture is presented to one of the eyes, human does not notice the degradation of the picture presented to the other eye. Using above-mentioned characteristics, it is possible to compress and transmit the multi-view motion pictures without noticed by the observer.In this research project, modified simulcast encoding method in which one of the positions in multi-view motion pictures is encoded by MPEG2 is proposed. Parallax compensation against reference pictures are applied to the other pictures, and the residual pictures are encoded in low space and time resolution. The amount of the information required to encode these pictures is about one tenth compared with MPEG2.The method can be applied to broadcast stereo pictures in the same bandwidth as conventional single channel program.

在作为运动图像的标准编码方法的MPEG 2中，由于头部等所花费的信息，难以减少编码信息量。在立体运动图像中，已知如果高分辨率图像呈现给一只眼睛，则人不会注意到呈现给另一只眼睛的图像的劣化。利用上述特性，它是可能的压缩和传输的多视点运动图像而不被observer.In本研究项目中，修改联播编码方法，其中的一个位置在多视点运动图像的MPEG 2编码提出。针对参考图片的视差补偿被应用于其他图片，并且残差图片以低空间和时间分辨率被编码。编码所需的信息量约为MPEG 2的十分之一。该方法可在与传统单通道节目相同的带宽内用于立体声图像的广播。
