Aspect Ratio Settings Aspect Ratio Input The Aspect Ratio Input field is a «read only» information that displays the input video’s 16:9 aspect ratio format. Aspect Ratio Output The XVC-1001-DC’s output Aspect Ratio is always 4:3. Converting a HD 16:9 ratio image into a SD 4:3 ratio image can be done in a variety of ways.
XVC-1001-DC Guide to installation and operation Anamorphic: Scales the 16:9 input image to fit horizontally and vertically into the 4:3 output image. The image is compressed and deformation will occur. Letter Box 25%: Scales the 16:9 input image to fit horizontally into the 4:3 output image, leaving a blank area equal to 25% of the image’s height (12.5% on each side). The original image is complete.

XVC-1001-DC Guide to installation and operation Film-Based and Pixel-Based Content In order to perform the best scaling, the XVC-1001-DC has to detect the presence of film-based content in video signals, and the presence of video (pixel based) content over film-based content. Film Sequence Detection Film sequences are transfered to video using various pulldown cadences. The film to video transfer may create artifacts in the image.
Guide to installation and operation XVC-1001-DC De-Interlacing Pixel-Based The XVC-1001-DC can detect the presence of film-based content in video, and merge fields to recreate the original image sequence prior to downscaling. When pixel-based images (logo, credits, etc.) exist over film-based content in the interlaced video, the XVC-1001-DC uses specific de-interlacing algorithms to yield the best results.

Guide to installation and operation XVC-1001-DC Technology Overview Aspect Ratio The aspect ratio of an image is its width divided by its height. Aspect ratios are mathematically expressed as x:y and x×y. Two common videographic aspect ratios are 4:3, universal for standard-definition video formats, and 16:9, universal to high-definition television and European digital television. Other cinema and video aspect ratios exist, but are used infrequently.
Guide to installation and operation XVC-1001-DC More advanced de-interlacing techniques include frame-based, motionadaptive de-interlacing. This is essentially the same technique described above however, by using a simple motion calculation, the video processor can determine when no movement has occurred in the entire picture. If nothing in the image is moving, the processor combines the two fields directly.
