Improvements relating to a progressive scan television

摘要

A television system (10) with interlaced to progressive scan conversion. The system receives interlaced television signals then converts them to progressively scanned data using either field differencing, enhanced field differencing, frame differencing or other temporal processing depending upon which implementation is used. The implementation used depends upon which configuration of the system (10) was purchased, and can be changed with an upgrade to one of the more expensive implementations. <IMAGE>
