Thel andand 1080i ATSC Video signalsInterlace to progressive (I/P) conversion for the 480i video format is accomplished viathe Video Signaling Processing IC, IC4010, and SDRAM IC4018 which serves as atemporary buffer during the interlaced to prSigI/P conVideo Signal FlowAll NTSC video signals are converted to digital data by the analog to digital (A/D)converter circuit located inside the Global Core IC, IC4011. The comb filter in IC40converts the composite video signal of the main picture to Y and C separated videdata. The S-Video signal, which is already Y/C separated, byChroma information is then applied to the Chroma Demodulator circuit that separatesthe color signal into PB and PR data.The Component inputs, which are already Y/C, separated; are converted to digitabypass the comb filter section of this IC4011. The 480psimply pass through the IC (which IC) and are output to the main global core IC,IC4011.ogressive conversion process. The Videonal Processing IC is responsible for Pixel conversion, White Balance, Aspect Ratioversion, Image resizing and LCD Panel control.Figure 2629
