Abstract
The technology is a system and method for selecting a television lineup. The available television lineups capable of being viewed on a digital device are identified. One of the tuner positions is selected and the television channel designated in each available television lineup identified. If any of the television channels identified is a likely identifiable channel and is designated by approximately half of the available television lineups, available television lineups may be deleted based on the television signal received by the selected tuner position. In on embodiment, the tuner positions are selected in numerical order. In an alternative embodiment, the tuner positions are first sorted before one is selected. It may not be possible to delete lineups based on likely identifiable channels. In this case, a viewer may be prompted to identify a channel.
