Provided are video encoding device that encodes high-quality video,restricting increase of the required bandwidth, while maintaining playbackcompatibility with playback devices conforming to MPEG-2 standard, and videoplayback device. Data creation device 5401 includes: 2D compatible videoencoder 2602 that generates stream conforming to MPEG-2 format bycompress-encoding original video of normal quality; base-view video encoder2605that generates stream, composed of black images, that includes the same numberofpictures as stream that is obtained by compress-encoding original video; anddependent-view video encoder 5409 that generates dependent-view video streambycompress-encoding higher-quality original video, by using, as referencepictures,pictures included in stream conforming to the MPEG-2 format that have the sametime information as pictures included in the base-view video stream thatcorrespondto pictures constituting higher-quality original video.
