Abstract:
1. A method for enabling channel selection for an electronic apparatus via a user input device having a key capable of being rotated and pressed, said method comprising: enabling selection of at least four channel numbers to form a first group; enabling selection of a first one of said channel numbers as a first initial channel number in response to said selection of said channel numbers in the first group; enabling display of said first initial channel number; enabling display of a second one of said channel numbers that is larger than said first initial channel number if said key is rotated in a first direction; enabling display of a third one of said channel numbers that is smaller than said first initial channel number if said key is rotated in a second direction, wherein only one of said initial channel number, said second channel number and said third channel number is displayed at a time; enabling selection of a fourth one of said channel numbers as a second initial channel number, wherein one of said second channel number and said third channel number is located between said first initial channel number and said second initial channel number, wherein at least two initial channel numbers are automatically selected by said electronic apparatus during a setup process so that the number of channel numbers between said initial channel numbers is approximately the same, and thereafter may each be adjusted upwardly and downwardly by a user; and tuning to the displayed one of said first initial channel number, said second channel number and said third channel number responsive to depression of said key, wherein after said first initial channel number is tuned to in said tuning step, switching from said first initial channel number to said second initial channel number responsive to further depression of said key.
