Abstract

The present invention is for more optimally performing recording and reproduction of stereoscopic video. In the present invention, parallax information is utilized to store, in a recording medium, stereoscopic video including left-eye images and right-eye images. Particularly, for video content that contains stereoscopic images, information is obtained regarding the amount of variation in parallactic angle having a given or larger value, a variation time that the variation in parallactic angle takes, and the number of times that the variation in parallactic angle occurs. An evaluation value is calculated that corresponds to the degree of eye fatigue on the basis of the amount of variation, the variation time, and the number of times of the variation. According to the present invention, the video content is encoded in such a manner that the evaluation value is within a given range, and then recorded in the recording medium.
