An image-processor system for compensating for accumulated phase-and-gain errors incurred during transmission of a video signal over a communications channel. The image-processor system comprises an initial-video processor, an input-video processor, a feature-video processor, a frame buffer, an RGB-output processor, an output-video processor, and a control processor. The initial-video processor generates a composite video signal. The input-video processor converts the composite video signal into digital-component signal information. The feature-video processor processes the digital-component signal information as processed component video information. The frame buffer re-establishes broadcast timing standards in the processed component video information to generate time-base corrected digital information. The RGB-output processor decodes the time-base corrected digital information into RGB analog and digital outputs. The analog RGB outputs are output directly. The output-video processor reconstructs the digital RGB outputs into an analog-composite video-signal format and an analog-component video signal component. The control processor loads and updates the parameters used by the input-video processor, the feature-video processor, and the output-video processor in processing the composite video signal.
