Abstract
A tuning system is provided which allows a user to enter into a memory text labels associated with respective channels to be tuned so that, thereafter, a channel to be tuned may be selected by the user by entering its label. The time required to search the memory for a match with a previously stored label during a channel change operation is minimized by storing the labels in alphabetical order, and performing a binary search of the area in memory in which the labels are stored.
