Abstract: A real-time video system (RVS), featuring programmable signal-processing elements, has been constructed for research on digital video signal processing. Except for input and output interfaces, the system is entirely digital, with 4fsc or 13.5-MHz sampling rates. A flexible architecture allows insertion of circuit boards with specialized functions in the signal pathway. Its capabilities are illustrated as they relate to proposed enhanced NTSC encoders and decoders using two-dimensional prefiltering of luminance and chrominance before modulation and two-dimensional bandpass filtering for chrominance extraction at the receiver. This technique virtually eliminates problems of cross color and cross luminance. RVS implements this technique using two-dimensional nonseparable finite-impulse response (FIR) digital filters.
