Description
svZX1 performs independent horizontal vertical zoom shrink scaling video graphics input data streams. (24/48-bit) YCbCr (4:2:2, 4:4:4, ITUR BT656) input video formats supported. output format 18/24/30/36/48/60-bit RGB, (with 4:2:2 YCbCr inputs) 16-bit 4:2:2 YCbCr, (with 4:4:4 input) 24/30-bit 4:4:4 YCbCr. Output data interlaced progressive scan. svZX1 capable shrinking UXGA 1920x1080i maximum input resolution SXGA resolution less. Inputs zoomed passedthrough) maximum SXGA display resolution. svZX1 requires external frame buffer when input output frame rates equal vertical active periods aligned same duration. Frame-rate conversion, desired, performed means external frame buffer controller (such Silicon Video svFC1A, successors svFC2). Color depth enhancement through dithering provided reduce color contouring effects output data. digital projector applications, electronic keystone correction allows image width correction when screen vertically aligned projector. overlay port allows external display synchronized data stream superimposed merged with displayed image. This enables svZX1 interface directly certain industry standard On-Screen Display (OSD) devices.
Features
Single-chip, fully programmable, independent image magnification/reduction. require external memory support typical formats. YCbCr hue, brightness, contrast, saturation control YCbCr color space conversion dual-pixel input rate 60Hz UXGA YCbCr/RGB inputs 75MHz supported Spatially de-interlaced, "sub-pixel positioned" shrink/zoom interlaced video input available Processes four combinations interlaced noninterlaced inputs outputs Provides data bypass mode Programmable horizontal vertical front back porches input data On-chip programmable 30-bit video look-up table gamma correction Horizontal keystone correction with sub-pixel positioning handles line length changes On-Screen Display Overlay supports programmable 24-bit colors, output clocks, `blending', common chips Industry standard 2-wire interface protocol supported High speed 3-wire 4-wire serial protocols supported 10MHz 33MHz Advanced input format detection easy selfconfiguration, centering, clock frequency sampling clock phase adjustment, interlaced field detect Multiple low-power modes Several methods synchronize input output clock domains Dithering logic optimized 18/36bit output Compatible with VESA FPDI-2, LVDS, TMDS package 3.3V supply with tolerant inputs

Keystone Corrected Display Active Window
Electronic keystone correction provided projection display systems. Keystone correction compensates trapezoidal image shape created when projecting image from angle perpendicular projection surface. compensation involves creating inverse trapezoidal image dimensions, such that when projected, displayed image again appears rectangular.
