Abstract
An autoprogrammer is provided for a television receiver capable of receiving conventional analog (NTSC) channels and DTV (8VSB) channels. First, conventional analog channels are identified and then skip channel data for each of the channels is stored in a memory. Subsequent executions of the autoprogramm function map DTV channels. Skip channel data is entered in the memory for these additional DTV channels. Mapping DTV channels occurs without deletion or overwrite of previous channel mapping information. Additionally information is stored in the skip channel memory giving antenna location for mapped DTV stations. DTV autoprogramming can be carried out at different channel positions.
