Abstract
The total running time of an original multi-channel program signal is altered to generate a time-shortened (or time-lengthened) program signal. The original program signal may be thought of subdividable into a sequence of program signal portions, each program signal portion being further subdividable into a sequence of signal windows. Differencing circuitry determines, for each program siganl portion, a difference value indicative of a best differnce match between an initial signal window in that signal portion and subsequent signal windows in that signal portion in accordance with a predefined criterion. Removal circuitry then deletes from the original multi-channel program signal a multi-window segment of that signal portion, the deleted segment beginning with the initial signal window and ending with the subsequent signal window that generated the best difference match.
