Progressive scan Progressive scan conversion produces double number lines field output. field frequency changed, while line frequency doubled. Processing progressive scan different successive output fields, e.g. first output field median operation lines, while second median operation even lines. PROGRESSIVE SCAN CONVERSION NON-INTERLACE MODE

Progressive scan-Zoom Noise reduction (PROZONIC)
Noise cross-colour reduction noise reduction field recursive with average ratio between fresh over previous fields averaged luminance chrominance. operating modes used principal: fixed adaptive mode (see Table fixed mode, averaging produces constant linear combination inputs. Except fixed mode should used normal operation, because smearing effects. adaptive mode, averaging ratio switches softly basis absolute differences luminance among inputs. When absolute difference low, only small part fresh data will added. When difference high, much fresh data will taken. This occurs either situation movement where significant vertical contrast seen.

latter remark, note that recursion done over field, pixel positions field apart always have vertical offset frame line. averaging only done dimension time also vertical direction. Therefore averaging vertically e.g. vertical black white edge would provide grey result this adapted for. averaging chrominance slaved luminance averaging. This implies that differences chrominance taken into account k-factor setting. noise reduction scheme effectively decreases both noise cross-colour patterns. cross-colour pattern does produce increase measured luminance difference, therefore this pattern will averaged over many fields.

Vertical sample rate conversion variable vertical sample rate conversion performed noise reduced progressively scanned data. vertical sample rate conversion intended cope with various letter formats, displayed displays with e.g. 16:9 aspect ratio. this sample rate conversion, which usually both vertical horizontal component, vertical sample rate conversion taken care PROZONIC, while horizontal compression done e.g. TDA8753A SAA4995WP. vertical sample rate conversion also used convert from NTSC lines source line display, setting vertical sample rate conversion factor necessarily some line-time reduction. Conversion from lines possible with progressive scan output, setting vertical sample rate conversion 5/6. principle vertical sample rate conversion based linear interpolation from successive lines video frame produce output line either field frame. vertical sample rate conversion factor switched following settings increasing number output lines w.r.t. number input lines; Table Table Vertical sample rate conversion factor OUTPUT LINES FACTOR 1.00 1.14 1.16 1.20 1.25 1.33 1.40 1.50 1.60 1.67 1.75 2.00 Movie phase detection
SAA4990H
While processing video, that originally film movement phases second case field rates), median filtering needed when fields combined that have same movement phase. this phase generally known, PROZONIC detection circuit help determine detection based measurement absolute luminance differences between successive input fields, pixel pixel. These differences summed over active video give number every field. case video from film with sufficient movement, measured number will alternately HIGH LOW. With controlling microcontroller, this data filtered appropriately switch movie processing correct phase. PROZONIC provision generate rectangular box, which position size programmable. This used enable measurement movie phase detection circuit, only within this rectangle. Otherwise, active video part field marked with derivative pulse. generation rectangular defined coordinates left-upper edge (hor_start_box, vert_start_box) right-lower edge (hor_stop_box, vert_stop_box). reference coordinates positive edge (with some processing delay) horizontal direction positive edge vertical. serve following purposes: Switch between adaptive fixed noise reduction. k-fixed then switches between adaptive noise reduced fully still picture areas. This provides option producing multi picture (still) images. noise reduction desired area where adaptive, adaptive setting programmed with steps zeros.

Reflow soldering Reflow soldering techniques suitable packages. choice heating method influenced larger plastic packages leads, more). infrared vapour phase heating used large packages absolutely (less than 0.1% moisture content weight), vaporization small amount moisture them cause cracking plastic body. more information, refer Drypack chapter "Quality Reference Handbook" (order code 9397 00192). Reflow soldering requires solder paste suspension fine solder particles, flux binding agent) applied printed-circuit board screen printing, stencilling pressure-syringe dispensing before package placement.
