Abstract
A two-mode limited channel television receiver includes a memory address counter for scanning the locations of a limited position memory in response to generation of a channel number by a channel number counter. Channel numbers and corresponding tuning information may be programmed into and deleted from the limited location only memory. In the programmed channel mode, memory locations with programmed channel numbers are accessed in channel number order. In the skipped channel mode, only unprogrammed channel numbers are produced and displayed to the viewer. In a variation, all channel numbers, both programmed and unprogrammed are produced and displayed. Empty memory locations are automatically accessed when an unprogrammed channel number is generated.
