Dual-channel video-graphics-controller for HDTV flat-panel display TV

This paper presents a high integrated high-performance video processing system-on-chip for HDTV displays. The IC unites the complete processing chain for dual-channel display and can be directly connected to a PDP or LCD by LVDS or RGB resp. It comprises a 3D-comb filter, two color-decoders, 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
