ABSTRACT:
A technique is disclosed for generating a progressively scanned video signal from an interlaced signal without the need for motion-adaptive processing. Low resolution information is obtained from the current interlaced field, and the remaining detail information is obtained from a stored signal that includes a prior field or fields. The obtained signal can then be displayed with progressive scanning at full resolution and without motion artifacts.
