Patent ID: 8149267

Claim:
A non-transitory recording medium, comprising: a base-view stream used for monoscopic video playback; a dependent-view stream used for stereoscopic video playback in combination with the base-view stream; a first file used in the monoscopic video playback; a second file used in the stereoscopic video playback; a shared stereoscopic/monoscopic area, the shared stereoscopic/monoscopic area being a physical area of the non-transitory recording medium; a dedicated stereoscopic area, the dedicated stereoscopic area being a physical area of the non-transitory recording medium; and a dedicated monoscopic area, the dedicated monoscopic area being a physical area of the non-transitory recording medium, wherein the shared stereoscopic/monoscopic area is accessed both in the stereoscopic video playback and in the monoscopic video playback, wherein the dedicated stereoscopic area is accessed in the stereoscopic video playback, wherein the dedicated monoscopic area is exclusively accessed in the monoscopic video playback and is not accessed in the stereoscopic video playback, wherein a plurality of base-view data blocks recorded in the shared stereoscopic/monoscopic area are formed from the base-view stream, wherein a plurality of base-view data blocks recorded in the dedicated stereoscopic area are formed from the base-view stream, wherein a plurality of base-view data blocks recorded in the dedicated monoscopic area are formed from the base-view stream, wherein the plurality of base-view data blocks recorded in the dedicated monoscopic area are identical to the plurality of base-view data blocks recorded in the dedicated stereoscopic area, wherein a plurality of dependent-view data blocks recorded in the shared stereoscopic/monoscopic area are formed from the dependent-view stream, wherein a plurality of dependent-view data blocks recorded in the dedicated stereoscopic area are formed from the dependent-view stream, wherein the first file refers to the plurality of base-view data blocks recorded in the shared stereoscopic/monoscopic area and to the plurality of base-view data blocks recorded in the dedicated monoscopic area, wherein the second file refers to the plurality of base-view data blocks recorded in the shared stereoscopic/monoscopic area and to the plurality of base-view data blocks recorded in the dedicated stereoscopic area, and wherein the second file has a plurality of packet numbers for a plurality of top packets of the plurality of base-view data blocks recorded in the shared stereoscopic/monoscopic area and the plurality of base-view data blocks recorded in the dedicated stereoscopic area.
