Abstract:
1. An apparatus that alters the total running time of an original multi-channel program signal that includes a plurality of individual channel signals, each individual channel signal being subdividable into a sequence of channel signal portions, each channel signal portion being subdividable into a sequence of channel signal windows, the apparatus comprising: for each of two or more of the plurality of individual channel signals, a corresponding differencing circuit that receives said individual channel signal and determines, for each channel signal portion of said individual channel signal, a difference value indicative of a difference between a characteristic of an initial channel signal window in said channel signal portion and a characteristic of a subsequent channel signal window in said channel signal; a difference value combining circuit that receives the difference values from each of the differencing circuits and combines said difference values to generate an overall difference value for a corresponding program signal portion of the multi-channel program signal; and a removal circuit that deletes from the original multi-channel program signal a multi-window segment that begins with the initial channel signal window and ends with the subsequent channel signal window.
