When the flag is set, it indicates that the recorded contents are the user's own contents, to be recorded on a DVD-R for General or a DVD-RW disc.

The contents to be recorded must not be covered by any copyright.
In each Part 1, a flag, named ADP_TY*³, is defined and set up for each physical sector in the Data area of a disc to distinguish where a user's own Audio/Visual contents are recorded from a disc where commercial ones are replicated. When the flag is set, it indicates that the sector contains material based on the DVD-Video Format.
