Dual-channel Video-Graphics-Controller for HDTV Flat-Panel Display TV

Abstract

This paper presents a high integrated highperformance video processing system-on-chip for HDTV displays. The IC unites the complete processing chain for dualchannel display and can be directly connected to a PDP or LCD by LVDS or RGB resp. It comprises a 3D-comb filter, two colordecoders, two channel motion adaptive de-interlacer with a new algorithm to eliminate staircase effects, as well as scaling, picture-improvement and frame-rate conversion processing units. A powerful 32 bit CPU controls internal and external tasks and a high-resolution pixel-graphic is generated for on-screen menus and teletext display.
