Abstract:
1. A non-transitory computer-readable recording medium storing a base-view stream file and a dependent-view stream file recorded thereon, the base-view stream file to be used for monoscopic video playback, the dependent-view stream file to be used for stereoscopic video playback in combination with the base-view stream file, the recording medium comprising a contiguous area in which a plurality of base-view extents belonging to the base-view stream file and a plurality of dependent-view extents belonging to the dependent-view stream file are arranged in an interleaved manner, wherein: a lower limit of a size of each base-view extent is set at a larger one of a first lower limit value and a second lower limit value so that buffer underflow does not occur in a playback device during both monoscopic video playback and stereoscopic video playback; the first lower limit value is determined by a value proportional to a jump time from each base-view extent to a next base-view extent during monoscopic video playback; the second lower limit value is determined by a value proportional to a read time of a next dependent-view extent after each base-view extent during stereoscopic video playback; a lower limit of a size of each dependent-view extent is set at a third lower limit value so that buffer underflow does not occur in a playback device during stereoscopic video playback; the third lower limit value is determined by a value proportional to a read time of a next base-view extent after each dependent-view extent during stereoscopic video playback; a dependent-view extent is arranged at the head of the contiguous area; an n during monoscopic video playback by a first playback device that includes a first read buffer and a first decoder, when (i) a jump time T an (n+1) during stereoscopic video playback by a second playback device that includes a second read buffer, a third read buffer, and a second decoder, when (i) each base-view extent is read into the second read buffer at a rate R during the stereoscopic video playback, when the dependent-view stream file is transferred from the third read buffer to the second decoder at a mean rate R
