A channel number data entry system for a television receiver employing a numeric keyboard allows the selection of cable channels having channel numbers greater than 99, without the use of a separate ENTER or 100s key. Specifically, if a predetermined unused or invalid channel number, such as 00, is entered, then the on-screen display message 1-is generated, and a three digit channel entry mode is enabled. If a valid and used two digit channel number is entered, then a two digit channel entry mode is enabled. In both modes, the desired channel is tuned upon receipt of the final digit of the channel number. |
