Abstract
An apparatus which easily discriminates 3D (stereoscopic vision) contents from non-3D contents among recorded program contents can be provided. Further, a unit to prohibit unintentional generation of a virtual play list where 3D contents and non-3D contents are mixed can be provided. For these purposes, a 3D flag is recorded in a play list file. Further, upon virtual play list generation, the recorded 3D flag set values are obtained and it is checked whether or not 3D contents and non-3D contents are mixed.
