<p>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.</p> |
