Abstract
A system and method allows a television viewer to select a channel without having to pre-select the source of the television signal received. If a conflict occurs in that multiple sources such as a satellite system, high definition television (HDTV), or cable TV all utilize the desired channel, then the system informs the viewer on the television display of the conflict and prompts the viewer for the desired source for the selected channel.
