method of creating a subset of channels programmed from a plurality of channels and system for creating a subset of channel indicators for channels programmed from a plurality of channels

摘要

"method and system for creating a subset of programming channels". The present invention describes a method (200) and system (100) for creating a subset of channels programmed from a plurality of channels and may include the steps of: receiving (210) a plurality of channels, wherein the plurality of channels comprises at least one programmed channel; encoding (212) at least a portion of a predetermined number of channels from the plurality of channels to provide a corresponding coded signal for each of the predetermined number of channels; processing (214) each of the corresponding coded signals to determine which of the predetermined number of channels contain programming to provide the subset of programmed channels; and storing (216) the subset of channels in memory. The present invention may further include the step of analyzing at least a portion of an audio signal on the predetermined channels to determine which of the predetermined channels contain programming.
