Abstract Of The Disclosure A composite video signal recorded in a non-standard encoding format is rearranged in a format which can be decoded by standard television circuitry. Simplified circuitry utilizing a relatively inexpensive, narrow band delay line is provided for separating the luminance and chrominance signal components from the non-standard signal. Additional circuitry recombines the separated signal components into a desired composite signal format. Filters are incorporated for providing attenuation to particular frequency regions of the luminance and chrominance signals for effecting a relatively uniform frequency response in the resultant composite signal. - 1 -
