<p>In a digital television signal processor (22), digital television channel viewing status (e.g., blocked or viewable) (50) is stored (32) according to the physical channel number (48) of a digital television channel rather than its virtual channel number (46). In this manner, the selected state (e.g., blocked or viewable) (50) 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 (46) of a digital television channel may not be the same as the physical channel number (48), storing the selected state of a digital channel according to its physical channel number assures that the selected viewing state is followed.</p> |
