Abstract
In the context of a video signal raster mapper, apparatus is disclosed to facilitate time compression or expansion by developing an auxiliary signal (DX) representing a fractional position of output pixel samples between input pixel samples. A multiplexer selectively applies values from two registers to an accumulator for controlling the accumulator value in a manner appropriate for compression or expansion.
