Abstract
A digital processing system that generates signals for multiple digital video systems and formats including the specific case of D2. The output is either from direct memory or component memory; encoded to composite at line rate, then and scan rate converted to subcarrier rates. The scan rate conversion process includes multiplication process of the signal by coefficients that are changeable with the signal so that conversion error is minimized. A single line of direct memory can be switched in for direct comparison of the outputs to allow detection of scan and encoding errors.
