Progressive Scan

Progressive Scan is a way of drawing every line in a video signal in sequence. Before this interlaced scans were used which only drew every other line, so a progressive scan is not only faster but it is smoother. Television before HD used interlaced video and this produced less of a flickering image than a progressive scan so is still the norm for many sets.
