  • Publication number: 20050114889
    Abstract: A method for searching television channel is provided. An initial frequency and a frequency search interval are set. Thereafter, using the initial frequency as the starting point, television signals are scanned to find any television channel within a designated frequency bandwidth. The channel ID is resolved from the channel frequency based on a specific broadcasting system on each detecting of the channel signals. The channel frequency and frequency ID of any television channel thus found are also stored. In this invention, the television channel is searched by frequency instead of a channel table as in a conventional method.
