vx15 31 preliminary product brief high quality progressive video processor 0 21022 p. 1 /p. 3 description VX1531 is vxis ? s first 5-in-1 progressive video processor ic, consists of vxis ? s third generation 3-d video deinterlacer, picture enhancement engine, the scaling engine specially designed for video apps ? the relcs, tv video encoder, and analog tv-on-pc switching circuits. it receives digitized interlaced video stream from ntsc / pal / secam video decoder or mpeg video decoder, performs high quality picture enhancement such as video noise reduction, sharpening, black-level extension, and gamma correction, and converts it into non-interlaced formats for direct display on progressive devices, such as lcd displays, hdtv, projectors, or pc monitors. its output resolution covers conventional vesa standard formats including vga (640x480), svga (800x600), xga (1024x768), sxga (1280x1024), and wsxga (1440x1024). with VX1531 ? s standalone application (no external dram required), VX1531 provides high quality single-field progressive-scan video with vxis ? s edge- preserving pixel interpolation algorithm for most cost-effective application. for the application where the cost of optional external sdrams is affordable, VX1531 provides theater quality progressive-scan video with vxis ? s motion-adaptive 3-d deinterlace algorithm , arbitrary ratio period-smoothened frame-rate conversion, synchronization-regeneration, and automatic source mode detection. the 3- channel digital to analog output converters (dac), font-based on-screen-display (osd), tv-on-pc switches, and tv video encoder were all intended to be built-in in VX1531 to make it become a highly integrated, most cost-efficient, and of course, a high-end progressive video processor. application n progressive hd tv n progressive dvd player n lcd tv n pdp tv n projection tv n multimedia monitor n tv-box application diagram two-wire host interface micro-controller video decoder or mpeg 2 decoder interlaced itu-u bt.656/601 or rgb digital video pc cpu vesa standard 16-bit sdram interface 16-bit sdram progressive ypbpr or rgb interlaced ypbpr or rgb vesa standard blended with video VX1531 progressive display devices tv or interlaced display devices progressive display devices vxis technology corp ., reserves the right to change or modify the information contained herein without notice. contact vxis or visit the website to ensure the most recent revision of the document.
