An Index.bdmv file is recorded in a BDMV directory of a rewritable recording medium. The Index.bdmv file contains an editability_flag and an extended_editability_flag. When the recording medium is loaded into a device, the editability_flag specifies whether the recording medium will be handled as an editable medium by the device. For a legacy device that does not support 3D video recording or editing, the recording medium is handled as a non-editable medium by means of the editability_flag being set to OFF. When the recording medium is loaded into a non-legacy device that supports 3D video recording and editing, even if the editability_flag is set to OFF, the extended_editability_flag specifies that the recording medium will be handled as an editable medium by the non-legacy device, and that editing of a stream file is possible.
