Apparatus and method for parental control using V-Chip plus+ and master password |
摘要 |
A method and apparatus for exercising access control over television programs using a parental control user interface that has different functions is provided. The method requires a password to enter into a master mode for obtaining access to all the functions of the parental control user interface. Once in the master mode, the user may enter a criterion for blocking a television program from being viewed or recorded or the user can override an already blocked television program. If a user, not in the master mode, attempts to watch or record a program that meets the blocking criterion and the program does not meet the overriding criterion, a prompt is provided to the user to enter the password. Upon entering a correct password, the program is unblocked. |
