Abstract: A matrix for digital video signals separates each coefficient into a binary part and a remainder. The binary part can be implemented very simply by a hardwired right shift. The remainder can be implemented using a ROM. Less ROM memory space is required than for implementing the entire coefficient in a ROM.
