Abstract

　ＤＶＤ＋ＶＲ記録方式において、ＶＣＰＳ（Video Content Protection System）非対応機器で著作権保護記録されたＶＣＰＳタイトル（２０４）を記録する際、ＶＣＰＳタイトルの手前にプロテクト属性を持つダミータイトル（２０３）を配置し、ＶＣＰＳ非対応機器用のタイトル管理情報にはＶＣＰＳタイトルに関する情報は含まないが、ダミータイトルに関する情報を含むようにする。これにより、ユーザーがＶＣＰＳ非対応機器でＶＣＰＳタイトルの手前にある削除済みタイトルから上書き記録しようとした場合にも、ダミータイトルがプロテクト属性を持つために記録が停止し、ＶＣＰＳタイトルを削除してしまうことを防止する。
