Abstract
A video signal processing system uses a sequence of interpolation filters to resample a 125M video signal to produce a 244M signal. In addition, the system allows an operator to specify a desired subcarrier-to-horizontal sync (SCH) phase and a desired horizontal position. The system automatically adjusts the starting point in the sequence of filters used for the resampling operation to implement each of the requested phase shifts.
