In a digital television signal processor, digital television channel viewing status (e.g., blocked or viewable) is stored according to the physical channel number of a digital television channel rather than its virtual channel number. In this manner, the selected state (e.g., blocked or viewable) of a digital channel's viewing status is implemented regardless of whether an off-air guide containing virtual channel number data is enabled or disabled. Since the virtual channel number of a digital television channel may not be the same as the physical channel number, storing the selected state of a digital channel according to its physical channel number assures that the selected viewing state is followed.
