Abstract

Two CMOS VLSI devices have been introduced which, through the combination of digital signal processing and external DRAMs, allow the display of television signals with higher quality and with more features. One device allows the simultaneous display of two independent video sources, while the other increases displayed picture quality by doubling the field display frequency to eliminate large area flicker. The second device also allows numerous extra features by manipulating both on- and off-chip memory. The devices can be combined within the same system to allow improved display quality plus an extremely wide range of additional display features
