Abstract
A video processor, having an input and an output, for compensating for accumulated phase and amplitude errors encountered during transmission of a video signal over a communications channel. The video processor includes a high-pass filter and amplifier, coupled to the input; a post-correction-phase-and-gain restorer; a wide-band-video-delay line coupled to the input; a pre-correction-gain restorer; and a combining network, coupled to the output. The high-pass filter has a bandwidth characteristic which is approximately inverse to a low-pass characteristic encountered by the video signal during its transmission over the communications channel. The high-pass filter takes the video signal and outputs a filtered-video signal. The amplifier associated with the high-pass filter inverts the filtered-video signal. The post-correction-phase-and-gain restorer adjusts the inverted-filtered-video signal to generate a restored-video signal. The wide-band-video-delay line takes the video signal and delays the video signal by a half cycle at the subcarrier frequency to generate a delayed-video signal. The pre-correction-gain restorer buffers the delayed-video signal. The combining network combines the restored-video signal and the delayed-video signal. The output of the combining network is a composite-video signal.
