Abstract
As an embodiment of a moving picture encoding apparatus, a moving picture type judgment section judges whether an input moving picture is a stereoscopic picture and, when the moving picture is a stereoscopic picture, a stereoscopic picture identifier is set to “1” and a moving picture rotation section rotates the moving picture clockwise by +90 degrees or −90 degrees. On the other hand, when the moving picture is not a stereoscopic picture, the stereoscopic picture identifier is set to “0” and the moving picture is not rotated. Then, a moving picture interlaced encoding section produces an encoded bit stream by performing interlaced encoding of the moving picture and a stereoscopic picture identifier encoding section produces encoded information by encoding the stereoscopic picture identifier. Further, a multiplexing section produces a multiplexed encoded bit stream by multiplexing the above-mentioned encoded bit stream and encoded information.
