发明名称 Method of foiling copy protection for DVDs
摘要 A disc burner receives a disc to be copied and checks whether it is an original disc or a recordable disc. If it is an original disc, its contents are copied with a copy protection indication. If it is a recordable disc, a check is performed to determine if it has a copy protection indication and copying is performed only if allowed by said copy protection indication.
