ABSTRACT:
A purchaser of DVD unit establishes a list of users who may access the DVD unit, and corresponding restrictions that apply to each user. When a user attempts to play a DVD disc, the unit examines the DVD disc for parental management information. If the DVD disc does not contain the parental management information, then the unit will only permit access if the user has no content restrictions. If the DVD disc does contain the parental management information, then the unit will compare it to the restrictions applicable to the user. Where the parental management information indicates that the material exceeds the restrictions applicable to the user, the unit will not play the DVD disc.
