Foreword Welcome to the family of DVDO product owners! Anchor Bay Technologies is proud and pleased to return this truly great brand name to the marketplace for video technology users around the globe. It is our pleasure to bring you the iScan Ultra Video Processor, which we are sure will deliver years of reliable performance. First, a bit of history about our company. Anchor Bay Technologies is composed of the former founding team of DVDO Inc.
Introduction Thank you for purchasing the iScan Ultra™ Video Processor, featuring the world’s most popular video processing technology as created by the Anchor Bay Technologies Team. This product delivers a level of video quality among the very highest available today.
Installation and Set-Up System Requirements and Compatibility The iScan Ultra is designed to interface to displays that can accept a 480p/576p, 31.5KHz progressive scan video signal in analog RGB or Y-Pb-Pr (Component) video format, or digital DVI format. These displays include: 䊳 Projectors 䊳 HDTVs 䊳 Progressive scan and multi-media TVs 䊳 Plasma TVs 䊳 Computer monitors If you are not sure if your display is compatible with the iScan Ultra, please contact your local iScan dealer.
Installation and Set-Up (continued) Signal Flow Diagrams The following diagrams show two typical ways to use the iScan Ultra in a system. Figure 1a depicts a system where the iScan Ultra is used as the primary video switcher. Figure 1b depicts a system when the iScan Ultra is used in conjunction with an A/V Preamplifier/Processor or A/V Receiver.
Installation and Set-Up (continued) Typical System Configuration The iScan Ultra is usually placed between the display device and any video sources and acts as a source switch for the display.
Installation and Set-Up (continued) A common variation of this setup is to use an A/V receiver as the switch between all the sources, with the output of the A/V receiver being the only input to the iScan Ultra.
Installation and Set-Up (continued) Output Signal Connections Display-Side Input Connectors There are two output connectors on the back of the iScan Ultra: There are a number of different connectors used on displays, but the most common are the 15-pin HD-15 (VGA), BNC, and RCA connectors. Newer displays may also have the DVI digital video input connector as well.
Installation and Set-Up (continued) BNC Connectors Many home theater projectors do not have an HD-15 connector, in which case you can use an adapter cable to convert from VGA to the BNC connectors used on the projector. These adapter cables are readily available through most home theater retailers and have a VGA connector on one end and BNC connectors on the other.
Displays and Controls INPUTS VCR Component DVD player Satellite Aspect Ratio Alphanumeric Display Pass Thru Picture Control Output Control Front of Unit Once you have the iScan Ultra connected to your home theater system, there are several configuration parameters that you may adjust to output the proper signal format for your display device and optimize the image to your personal preferences.
Displays and Controls (continued) Alphanumeric Display Aspect Ratio Control For all video inputs except ‘Pass-Thru’, selecting ‘Aspect Ratio’, ‘Picture Control’, or ‘Output Control’ turns on the Alphanumeric Display. The iScan Ultra has a new Aspect Ratio Control feature that can be used whenever you are displaying 4:3 images on a 16:9 TV. This includes standard 4:3 full-screen or letterboxed images being played on a wide-screen TV.
Displays and Controls (continued) 4) SQ1 (Squeeze1): This is to be used when the source is 4:3 full-frame and the display is 16:9. It horizontally decreases the image size by a ratio of 3/4 and centers the resulting image horizontally with dark gray bars on either side of the image. 5) SQ2 (Squeeze2): This is to be used when the source is 4:3 full-frame and the display is 16:9.
Displays and Controls (continued) Hue As with Saturation, Hue can also be controlled independent of the display. Hue is the same as the “Tint” control found on most TVs and controls how colors are displayed in the image. The Hue control is not available for Component or PAL/SECAM inputs. YC Delay Sometimes there is a lag between the Luminance (Y) and the Chrominance (C, UV) of the video signal.
Displays and Controls (continued) Output Control There are only two outputs for the iScan Ultra, but there are various formats that may be used for each. Please consult your display device’s specifications to determine which input signal formats it accepts. Color Space Display devices generally work in YUV/YPb-Pr (Component) or RGB color space. Some can work with both. Consumer electronics displays generally operate in YUV/Y-Pb-Pr (Component) color space.
Troubleshooting The iScan Ultra has been designed to process standard interlaced NTSC/PAL/SECAM video inputs, and output 480p/576p progressive scan video at 31.5kHz/31.25kHz scan rates. A digital video DVI output can also be generated from an NTSC or PAL/SECAM input, but not from the Pass-Thru input. The iScan Ultra should work with a typical home theater system. Below are some steps to take when experiencing the problems below.
Troubleshooting (continued) If the computer monitor displays the video, then the problem is either in the original video output cable, its connection to the display, or the display itself. 7) Try a different output cable with your display. 8) Verify that all the Output Controls are set correctly. 9) Verify that your display is capable of accepting a 31.5 KHz input. If no image is observed, or the computer monitor does not render an image, the iScan Ultra may be defective.
How It Works Background On a standard CRT-based television, the video image is created by sweeping an electron beam across the face of the set where it excites phosphors, causing them to glow. The television changes the intensity of the beam to vary the brightness of the image. If you look closely at the picture on a television set, you will see the horizontal scan lines that make up the image.
How It Works (continued) Deinterlacing Deinterlacing is the process by which interlaced video is converted to progressively scanned video. Progressive scanning paints all of the lines of a frame in one top to bottom pass. This is used where transmission bandwidth is not an issue and where the highest quality image is required. None of the interlaced side effects are present with progressive scanning.
How It Works (continued) The iScan Ultra performs excellent 3:2 pulldown detection. In addition, it also recognizes the 2:2 pulldown sequence used for converting PAL film and computer graphics to video. For these film and computer graphics sources, the iScan Ultra will reassemble the original progressive frames with no unnecessary filtering of image detail.
