Abstract
A television tuning system includes apparatus for swapping or exchanging a presently selected channel for a previously saved channel when a user operates a switch provided for that purpose. The apparatus is arranged so that the saved channel is unaffected by channel selections so that it may be used by a user to quickly return to an originally selected channel after scanning other channels, e.g., during commercial interruptions, as well as to follow the progress of two programs, e.g., two sporting events on different channels.
