ABSTRACT:
The invention concerns a method (200) and system (100) for creating a subset of channels with programming from a plurality of channels and can include the steps of: receiving (210) a plurality of channels, wherein the plurality of channels comprises at least one channel with programming; encoding (212) at least a portion of a predetermined number of channels from the plurality of channels to provide a corresponding encoded signal for each of the predetermined number of channels; processing (214) each of the corresponding encoded signals to determine which of the predetermined number of channels contain programming to provide the subset of channels with programming; and storing (216) the subset of channels into memory. The invention can also include the step of analyzing at least a portion of an audio signal in the predetermined channels to determine which of the predetermined channels contain programming.
