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 interface that has different functions are provided. The method requires a password to enter into a master mode for obtaining unlimited access to all the functions of the parental control 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. Once a master password is entered, the system is in a Master Password mode until the TV is turned off, the user exits the VChip Plus+ mode, or a certain time delay expires. 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.
