Silicon Image, Inc. iScan Pro User Manual Introduction Your iScan Pro package contains: • • • • • • • iScan Pro Line Doubling Upconverter Universal power supply module Power cable Composite video input cable S-Video input cable Component video input cable User Manual Your iScan Pro package does not contain an output cable. You will need to purchase an output cable that works with your display device. There is more information on these cables in the Installation section.
Silicon Image, Inc. iScan Pro User Manual Installation and Setup Typical Configuration Figure 1 shows a typical configuration for a home theater system. In this setup, the iScan Pro is being used to enhance the output from a DVD player, a satellite receiver and a VCR before the selected signal is sent to a rear screen projection TV, or another progressively scanned display device.
Silicon Image, Inc. iScan Pro User Manual System Requirements The iScan Pro is designed to interface to 31.5 kHz progressively scanned display devices such as: • • • • • • Data projectors Home Theater video projectors (31.5KHz scan rate required) HDTVs Progressive scan and Multimedia TVs Plasma TVs Computer monitors If you are not sure whether or not your display will work with the iScan Pro, contact your dealer or check the compatibility list on our web site at www.siimage.com.
Silicon Image, Inc. iScan Pro User Manual For progressive scan TVs / monitors / projectors with VGA input: A high quality VGA-to-VGA computer monitor cable should be used to connect the iScan Pro’s output to devices that can accept progressive signals through a VGA connector. For progressive scan TVs / monitors / projectors with BNC input connectors: Many high-end TVs, monitors and CRT projectors have BNC input connectors.
Silicon Image, Inc. iScan Pro User Manual Color Space Selection The iScan Pro can output video in one of two different color spaces. The first is the Red-Green-Blue (RGB) color space that is commonly used for projectors, displays and monitors that are designed to accept computer video output. The second is Component Video, but is more accurately called YPbPr though you may hear it referred to as Y-Pr-Pb, YUV, Y-Cr-Cb or Y/B-Y/R-Y (read “Y, B minus Y, R minus Y”).
Silicon Image, Inc. iScan Pro User Manual With YPbPr connections, the composite sync is always combined with the Y signal. The iScan Pro will automatically do this whenever the color space switch is set to YPbPr. It is not required to configure any of the internal jumpers for any YPbPr device.
Silicon Image, Inc. iScan Pro User Manual Operation Input Selection The iScan Pro has been designed to detect which one of the three possible input devices are turned on and are generating video signals and then automatically switch to this input. With this capability, you can switch inputs simply by turning one input device on or by turning another device off.
Silicon Image, Inc. iScan Pro User Manual Since nearly all televisions sold are CRT-based, it is likely that the gray bar setting is the safest for your display. However, LCD and DLP-based projectors and displays do not suffer from burn-in so it is safe to use the black bar setting. Picture Controls The iScan Pro provides the ability to adjust five picture control settings.
Silicon Image, Inc. iScan Pro User Manual Troubleshooting ♦ What do I do if no LEDs light when I plug the power supply? The iScan Pro should automatically come “on” when plugged in. Check the connections to the iScan Pro, and to the power source. If all of these look good, you may have a failed power supply or a failed unit. ♦ What do I do if the power is on but I get no picture on the screen? The basic troubleshooting procedure is: 1) Check the Power indicator.
Silicon Image, Inc. - ♦ iScan Pro User Manual Insert just the Pr (red) signal into the Pr connector. This should result in a red picture. Remove the Pr and insert the Pb into the Pb connector. This should give you a blue picture. If one or the other of these combinations does not give the expected results, it may be a problem with the output cable or the input connectors on the display. Try plugging the Pr connector into the Pb input and verify that the video is blue.
Silicon Image, Inc. iScan Pro User Manual How it Works Background On a normal television, the video image is made by sweeping an electron beam across the face of the set where it excites phosphors causing them to glow. While repeated scanning across the tube, 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.
Silicon Image, Inc. iScan Pro User Manual 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.
Silicon Image, Inc. Video Source Analog to Digital Conversion iScan Pro User Manual Decoding NTSC to Component Deinterlacing I to P SiI503 Chip Digital to Analog Conversion Display or Projector (DV103) Figure 3: System Block Diagram Video Processing All of the processing steps in the signal chain between your video source and the display influence the quality of the image. The following are brief descriptions of the series of steps shown in Figure 3. 1. 2. 3. 4. 5.

Silicon Image, Inc. iScan Pro User Manual Warranty Information LIMITED WARRANTY. Silicon Image, Inc. Warrants only to the initial purchaser of this product who returns the warranty card accompanying this product, for a period of one year from the purchase date, that the product will be free of mechanical defects that materially affect the product’s operation as described in this manual.
Silicon Image, Inc. iScan Pro User Manual Safety Information: Safeguards ♦ ♦ To reduce the risk of electric shock, do not expose this appliance to rain or moisture; do not operate the iScan Pro with the cover removed. If the wall plug does not fit into your local power socket, then ask your electrician to replace your obsolete outlet. Do not modify the wall plug. To do so will void the safety feature.
Silicon Image, Inc. iScan Pro User Manual Appendix A – Internal Jumper Settings These modifications are only required in very rare circumstances. Composite Sync and Sync-onGreen are only required in RGB mode (never Component/YPbPr mode) and typically only with older, large front projectors. The rule of thumb is if you are seeing a picture on your display, then you have the sync settings correct.
Silicon Image, Inc. iScan Pro User Manual Rear of board Modifying Composite Sync Jumper Setting 1) To configure the unit to output Composite Sync, locate the connector labeled “J-10”, as shown. A plastic jumper should already be straddling the two pins closest to the “NORMAL” label. 2) Move this jumper from its current position to the two pins closest to the “CSYNC” label as shown below.
