Interlaced and progressive scan
A progressive scan is a method of updating the image by drawing all the lines of each fram\
e in a sequence. In contrast, interlaced
video alternately scans odd and even lines. In old analog TV interlacing was commonly used as a way of doubling the refresh rate w\

2:3:3:2 (advanced) pulldown
This method is very similar to the normal pulldown. Unlike the normal pu\
lldown method, the resulting 30 fps video sequence contains only one
frame containing fields from two different source frames.
The advantage of this method is that it is easier to reverse, if necessa\

page 123 Reference Guide APPENDIX B: LENS CHARTS Appendix B: Lens Char ts How to use the lens charts The lens charts on the following pages provide a quick guide to the type of lens needed for a particular projector. To use the lens charts, you need the following information: • The DMD™ resolution of your projector • The distance between the projector and the screen (throw distance) • The maximum width of your screen In the chart for the required DMD™ resolution, find the point where the throw distance corresponds to the screen width, as shown in the example below. Example For a 1080p projector with • throw distance 14 m, and • screen width 3.5 m, the correct lens would be number 6 in the chart. Notes For information about individual lens part numbers, see Appendix A earlier in this document. 12 1Screen width 2Throw distance 1234567 1 m (3.3 ft) 2 m (6.6 ft) 3 m (9.8 ft) 4 m (13.1 ft) 5 m (16.4 ft) 6 m (19.7 ft) 5 m (16 ft) 10 m (33 ft) 15 m (49 ft) 20 m (66 ft) 25 m (82 ft) 30 m (98 ft) 35 m (115 ft) 40 m (131 ft) Screen width Throw distance Digital Projection HIGHlite 660 3D Series Rev E Februar y 2015
page 124 Reference Guide APPENDIX B: LENS CHARTS How to find the right lens chart Charts are shown in order of DMD resolution, as follows: • 1080p • WUXGA For each resolution, the available lenses are shown in different charts depending on applicable throw ratio corrections (TRC). For each resolution, lens charts are arranged in ascending TRC order, starting from full width images, where TRC=1. Full width images are grouped together. 1080p and WUXGA are shown in the same chart. 1080p (1920 x 1080 pixels) Full width images Formats that fit the width of the DMD™ without applying a throw ratio correction (TRC) include: • 2.35:1 (Scope) 1920 x 817 pixels TRC = 1 • 1.85:1 (Flat) 1920 x 1037 pixels TRC = 1 • 1.78:1 (16:9) 1920 x 1080 pixels (native resolution) TRC = 1 Full height images A throw ratio correction (TRC) has been applied to the following charts\ : • 1.25:1 (5:4) 1350 x 1080 pixels TRC = 1.42 • 1.33:1 (4:3) 1440 x 1080 pixels TRC = 1.33 • 1.6:1 (16:10) 1728 x 1080 pixels TRC = 1.11 • 1.66:1 (Vista) 1792 x 1080 pixels TRC = 1.07 Notes For information about individual lens part numbers, see Appendix A earlier in this document.
