ABSTRACT:
There are different types of DVD systems, e.g. the replay-only DVD-Video system and the re-recordable DVD-VR system. A DVD-VR type disc containing a DVD-VR type bitstream is to be replayed on a DVD-VR type recorder or player. However, it is also possible to record a DVD-Video type bitstream on a DVD-VR type disc in a DVD-VR type recorder, for replay of that disc in a DVD-Video type player. Because the DVD-VR and DVD-Video formats are different and contain different content they are not compatible with each other and a disc containing a bitstream of the one type can not be replayed on a player of the other type, a user must make a choice of which type of bitstream recording on a disc. One solution to this problem would be to record a separate disc for each type of bitstream. According to the invention a special type of bitstream is assembled and recorded on a disc that can be replayed on both types of players. This special type of bitstream is compatible with the DVD-Video system as well as the DVD-VR system. For both systems, corresponding additional files are added to their specific directories, but the resulting bitstream for both system types represents the same identical file on the disc. A disc containing a bitstream having such data structure can be replayed on both, DVD-VR and DVD-Video players.
