Abstract
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 implementations used depend upon which configuration of the system (10) was purchased, and can be changed with an upgrade to the more expensive implementations.
Claims6
A television system which receives interlaced television signals, comprising:
- a receiver for receiving said interlaced signals;
- a processor for converting said signals into progressively scanned data, wherein said processor is operable to use one of several methods of converting said signals such that said processor performs motion detection between at least two fields of video data in any of said several methods;
- memory in communication with said processor for receiving data during and after said conversion, wherein said memory is capable of being expanded to include more memory, wherein said expansion of said memory allows for additional ones of said several methods and said expansion of said memory determines which of said additional methods are allowed;
- and
- a spatial light modulator for displaying said converted signals as a progressively scanned video image.
