Some Application of Digital Techniques in TV Receivers

Until comparatively recently the concept of using digital methods in consumer equipment was dismissed as impractical, unnecessary and prohibitively expensive. New developments in semiconductor technology, transmission systems and FCC regulations have brought about a situation where digital techniques are now not only economically and technically feasible but also necessary. Some of the factors involved include the availability of complex MOS LSI (Large Scale Integration) devices, the National Bureau of Standards time code transmission system and the UHF tuning parity regulations. This paper will endeavor to discuss these factors and how they may affect future TV receiver design.
