ABSTRACT:
A system converts digital video signals between two digital video signal formats. The system includes a rate converter which receives digital samples of the video signal in the first format and at the clock frequency thereof and converts those signls to digital samples of the video signal at the clock frequency of the second signal format. The outputs of the rate converter are combined with appropriate coefficients in a digital filter to produce alternately coefficient modified chorma and luminance signals which are combined in an output circuit to produce the digital video signal in the second video signal format.
