DVDO iScan Mini - 4K Scaler / Video Enhancement Overview Thank-you for purchasing the DVDO iScan Mini – 4K Video Scaler, Enhancement and Display setup tool. It is ideal as an add-on to an A/V Receiver or Video Processor to improve the picture quality of existing content on a 4K Ultra HD TV.
DVDO iScan Mini - 4K Scaler / Video Enhancement Blu-ray discs or streamed over the Internet in a highly compressed format. Artifacts generated from compression or the use of low quality scalers can result in reduced picture quality. iScan Mini is specifically designed to automatically upscale both SD and HD sources up to 4K resolution while enhancing original source content. Other key features also include video setup and adjustment tools, EDID editing, and S/PDIF digital audio output .
DVDO iScan Mini - 4K Scaler / Video Enhancement iScan Mini provides three scaling modes: - Auto mode scales anything up to 4K or the best resolution the display can handle - DVDO mode scales compatible frame rate input video to a manually chosen resolution for those who want more control - Off mode disables the iScan Mini’s scaler (set to 1:1 mode) while keeping other processing active The iScan Mini works just as well with 1080p displays, scaling and enhancing SD and 720p content, bringing out hidden

DVDO iScan Mini - 4K Scaler / Video Enhancement Connections iScan Mini is normally connected as the last device before the display HDMI input. It is small enough to be hidden behind an AVR or a wall mounted TV. It should be mounted in such a way as to make the IR receiver capable of receiving commands from the remote control. If this is not possible, an IR extender cable (http://www.monoprice.com/Product?c_id=109&cp_id=10110&cs_id=1011009&p_id=8060&seq=1&fo rmat=2 ) can be used.
DVDO iScan Mini - 4K Scaler / Video Enhancement SCALING The iScan Mini remote is specifically designed to allow fast access to controls. Auto: Automatically scale to the best resolution the TV supports DVDO: Scale to the specific resolution preset using the OSD Off: Let the TV handle all scaling ENHANCEMENT Low: DVDO preset, minor enhancements. Use for already “good” video to make it pop High: DVDO preset, extreme enhancement.
DVDO iScan Mini - 4K Scaler / Video Enhancement On-Screen Display and iScan Mini Controls Main Menu: Pressing MENU on the remote control brings up the main menu. The Up/Down/Left/Right and OK buttons are used to navigate within the menu system Information: The information screen provides basic information about the current status of iScan Mini input and output formats.
DVDO iScan Mini - 4K Scaler / Video Enhancement Info Pop-Up Window: Pressing the Info button on the remote control brings up a pop-up window that provides more information about current iScan Mini status including enhancement mode and scaling mode.
DVDO iScan Mini - 4K Scaler / Video Enhancement Enhancements: The Enhancement menu provides access to video adjustments, video processing settings, and allows the user to recall or save custom enhancement settings. All settings in this menu can be adjusted and saved to two User memories.
DVDO iScan Mini - 4K Scaler / Video Enhancement Enhancement Controls: The input type determines which controls apply to the video signal. Brightness, Contrast and Color apply to all video types and can be adjusted using the built-in test patterns. Brightness Adjusts the black level of the overall image from the iScan Mini. When you make an adjustment to brightness, all video levels, from black to peak white, are shifted up or down. Brightness is also known as Black Level adjustment.
DVDO iScan Mini - 4K Scaler / Video Enhancement Mosquito & Internet Noise Reduction will only affect SD video types and is used to reduce the effects of mosquito noise and video compression artifacts. Mosquito Noise is a type of image noise that is caused by video compression in cable, satellite and broadcasts. It is typically visible on SD content as a fuzzy ‘halo’ around object edges. Use higher setting for noisier images.
DVDO iScan Mini - 4K Scaler / Video Enhancement SD Smoothing will only affect SD video types and is used to reduce “jaggies” present in low resolution video before the signal is scaled DVDO iScan Mini 16
DVDO iScan Mini - 4K Scaler / Video Enhancement Detail Enhancement will affect both SD and HD video types and is used as an overall enhancement much like the Adobe unsharp mask. It sharpens fine aspects of the picture on a pixel by pixel basis. A high setting can make crisp images appear almost 3D and sharpen fine granular detail. No Enhancement Detail Enhancement Edge Enhancement Edge Enhancement will affect both SD and HD video types and is used specifically to sharpen object edges.
DVDO iScan Mini - 4K Scaler / Video Enhancement Ringing Suppression will affect both SD and HD video types and is specifically used to reduce ringing in high contrast areas of scaled video such as around black bars, text and graphics. The iScan Mini’s adaptive scaler will suppress ringing around scaled text and graphics while preserving the resolution of the natural video content. See the example below. Using ringing suppression, scaled video will look clean and smooth while maintaing detail.
DVDO iScan Mini - 4K Scaler / Video Enhancement HD Smoothing will affect SD or HD OUTPUT video types and is specifically used to smooth jaggies that occur around object edges after the video is scaled. The jaggies are very visible when the scaling ratio is large. In the example below the video is scaled from 480 to 1080. On the left you can see the jaggies created and on the right smoothed.
DVDO iScan Mini - 4K Scaler / Video Enhancement Scaling Modes From the scaling menu, you can choose one of three modes: Auto Mode: iScan Mini reads the capability of the TV (EDID) and passes that back to the current source. Once video is sent from the source, Mini determines if it can be scaled up to the native resolution of the display with the same frame rate (auto is always 1:1 frame rate). If something is provided that cannot be scaled, it is simply passed through with a warning message.
DVDO iScan Mini - 4K Scaler / Video Enhancement Modify EDID Basic display EDID editing is provided to allow forcing of specific resolutions by a professional installer. Modifying an EDID can result in improper or unexpected operation or no picture or audio. Please use this only if you are comfortable with EDIDs and have modified them before. Procedure for modifying EDID is: 1. Capture EDID from display 2. Modify EDID as needed – The on screen menu allows you to remove resolutions but not add them.
DVDO iScan Mini - 4K Scaler / Video Enhancement Tools Built-in tools allow display adjustment and evaluation of settings. Test patterns can be accessed through the OSD or directly from the provided remote control.
DVDO iScan Mini - 4K Scaler / Video Enhancement Demo Mode: This is a special mode that allows you to quickly see the results of applied enhancements. Split screen shows no enhancements on the left side and applied enhancements on the right. Slow and Fast moving bar also show applied enhancements on the left and no enhancements on the right. So as the ar sweeps across the screen it updates the picture real time. Note that enhancements are easier to see and adjust with a still image.
DVDO iScan Mini - 4K Scaler / Video Enhancement Audio Output to S/PDIF If there is a need to extract audio from the HDMI stream and output to S/PDIF instead (e.g. Soundbar, DVI only TV, or whole home audio feed), the iScan Mini optical S/PDIF audio output can be used. Note that while iScan Mini does not have an audio processor, the Audio menu does allow you to modify the audio part of the EDID so that the proper audio for your application can be requested from the source.
DVDO iScan Mini - 4K Scaler / Video Enhancement Updating Firmware iScan Mini allows simple firmware update through an attached PC. Firmware version can be checked using the OSD menu and accessing the information screen. Download the latest firmware from www.dvdo.com Press the F/W update button for 2 seconds while iScan Mini is connected to a PC via USB iScan Mini will be automatically installed as a removable drive.
DVDO iScan Mini - 4K Scaler / Video Enhancement Test Pattern List All loaded test patterns will be available from the IR remote and the OSD.
DVDO iScan Mini - 4K Scaler / Video Enhancement Test Pattern Explanations Frame & Geometry This test pattern contains two specific test features. The first is a 1-pixel wide box around the very outside of the image. This is used to determine when the entire iScan output image is visible on the display. The arrows along the middle of each edge provide an indication of the amount of overscan (if any). The blue boxes in the center of each quadrant are used for measuring display geometry.
DVDO iScan Mini - 4K Scaler / Video Enhancement Frame/Geometry Test Pattern (Image C) As you can see in image C, the test pattern is almost displayed correctly. You can see the 1-pixel wide white border on the top, bottom and left side of the image but not on the right side of the image. By adjusting the horizontal size of this signal to 1360 (rather than 1366), we can get this test pattern displayed correctly on our display.
DVDO iScan Mini - 4K Scaler / Video Enhancement be the native resolution of your display or your display may scale all input signals even if the input resolution is already at native resolution. Note: If this test pattern does not appear as it should and you have chosen the native resolution of your display, you may not be able to bypass the internal processing on your display. The ‘Vertical Lines’ test pattern should appear as one pixel wide black and white columns.
DVDO iScan Mini - 4K Scaler / Video Enhancement PLUGE patterns (2 white and 2 black) These patterns are used to visually adjust brightness (black level) and contrast (white level) as well as to verify the display is in the correct color space mode. RGB video is normally sent using all 256 bits (in 8 bit color) but YCbCr (component video) sets black at 16 and white at 238. This allows room above and below the active video for below black and above white.
DVDO iScan Mini - 4K Scaler / Video Enhancement Brightness & Contrast This test pattern is composed of 4 quarter-screen blocks. Two of the blocks have a background level of standard black, and the other two blocks have a background level of standard white. Embedded in the black blocks are 3 bars. One is 4 IRE below black, one is 1 IRE above black, and the third is 2 IRE above black. Embedded in the white blocks are 3 bars.
DVDO iScan Mini - 4K Scaler / Video Enhancement be ‘light’, not gray, with the details still intact. When the contrast is adjusted correctly, white objects will appear ‘white’ with the details still intact. Because the contrast settings can affect brightness settings we recommend that you check the brightness setting after making this adjustment. Note that the ISF PLUGE patterns are also an efficient way to set brightness and contrast.
DVDO iScan Mini - 4K Scaler / Video Enhancement Grey Ramp The ‘Gray Ramp’ can help verify that your display is showing the gradients between black and white correctly. You should see a smooth transition between black and white with this test pattern. This test pattern is a horizontal gray ramp. There is a black level (0 IRE) vertical bar along the left of the pattern and a white level (100 IRE) vertical bar along the right side of the pattern.
DVDO iScan Mini - 4K Scaler / Video Enhancement Solid colors These patterns are normally used with a color meter and software to read specific color levels. IRE stands for International Radio Engineers and it is a relative scale, NOT an absolute. It defines the volt peak to peak video divided up into 140 IRE units. This is done to make numbers for luminance levels easier to communicate.
DVDO iScan Mini - 4K Scaler / Video Enhancement Sharpness As its name implies, sharpness is used to adjust the sharpness control on a display. If sharpness is set too high, then single pixel black or white lines on a grey background will appear to have a halo. The top left of this screen (labels do not appear on the actual pattern) has a 1 pixel black cross and nearby single pixel white lines. Wider lines can be used to see the effect of sharpness control on larger video structures.
DVDO iScan Mini - 4K Scaler / Video Enhancement Troubleshooting: Issue: Possible Resolution: No picture or TV reports signal not supported iScan Mini is putting out a resolution or bit depth that the TV cannot handle. Press the button on the side of the Mini marked “scaling” until auto appears and a signal returns. Grey Ramp and/or Frequency Sweep cannot be selected These patterns are only available in YC modes – please provide a YCbCr input to switch to this mode.
