Abstract :
A bi-channel HDTV transmission system has been developed that digitally filters the video signal in accordance with known spatiotemporal properties of the bi-channel visual of system. Differential processing of high and low spatial-frequency information yields several distinct advantages that include: compatibility with existing broadcast systems and improved spatial resolution for both moving and stationary HDTV images with a reduced bandwidth.
