Abstract
A class of filters for use in connection with the sub-band coding of a video signal is disclosed. The filters are of short length, symmetric and have coefficients in the form of an integer divided by a power of two. The filters may be implemented with a minimum of circuitry and permit exact reconstruction of a sub-band coded video signal.
