Abstract
Improved channel mapping is provided wherein both virtual channel information associated with the currently-tuned channel, as well as physical channel information associated with this same channel is added to a television system's channel map. User inconvenience associated with errors in the virtual channel information may be mitigated since the television system's channel map will contain, not only the standard virtual channel information provided by broadcast stations in their broadcast signals, but also the corresponding physical channel information for the broadcast station in question. In other embodiments, multiple channel maps may be maintained and be user-selectable.
