How to set all channels in the TV channel viewing list to blocked or viewing status

摘要

A system, apparatus and/or method including or embodied as a television signal processor provides a user setting up a channel surf list or parental control list with the option of blocking (prohibit viewing) or unblocking (allow viewing) all available channels at once. This serves as a convenient starting point to save time before editing the channel list since if the user expects that most of the channels are to be blocked, one can start out by blocking all of the channels, then make some of the channels unblocked (i.e. viewable) and/or vice versa. In one form, separate channel surf or parental control lists pertaining to separate television signal inputs are maintained with each list provided with the global viewing status or state setting option.
