    摘要: A method of reducing channel scan time is achieved by knowing important location information such a zip code. This allows a locally stored database of available broadcast channels to be used to skip unused frequencies and to allow finding the direction of the most likely broadcast station. Once one active channel is located, it is possible to calculate the most likely direction to search for the remaining active channels in the data base using a smart antenna.
