Abstract
A controller in a CATV converter provides three operating modes comprising: (1) a family viewing mode in which conversion of selected channels is blocked; (2) an enter access code mode for selecting the channels to be blocked from family viewing; and (3) a parental control mode in which all channels may be viewed. The family viewing mode is enabled by turn-on of the converter or by commands by the user or the CATV system operator. The enter access code mode is initiated by a user command. The parental control mode is enabled by user entry of a valid access code or when a new access code is created while in the enter access code mode.
