Q: What Video Reference Series (VRS) technologies are incorporated into the iScan Duo?
A: iScan Duo incorporates Anchor Bay's Mosquito Noise Reduction, Fine Detail Enhancement, Edge Enhancement, Precision Deinterlacing, Precision Video Scaling, PReP (Progressive ReProcessing), Progressive Cadence Detection, RightRate framerate conversion, AutoCUE-C, and Precision AV LipSync.
Mosquito Noise Reduction
Video compression is a commonly used technique to squeeze more video content onto a disc, or beam down more channels via satellite, or transmit more channels over a cable. By using video compression content providers can achieve better economies of scale and offer the consumer more video content - e.g. more channels, bonus materials, etc. The problem with nearly all video compression methods is that too much of it causes compression artifacts. These artifacts are often seen by the viewer as ugly ringing around text letters or noise - often called mosquito noise. To counter this Anchor Bay has developed a proprietary method of selectively removing mosquito noise. Unlike some methods of noise reduction that often makes the image worse by removing too much detail or causing blurring during motion, Anchor Bay's Mosquito Noise Reduction is designed to isolate the most objectionable of artifacts without removing detail or causing motion blur. To do this Anchor Bay had to devise a proprietary method of both isolating and predicting areas in the image where this noise is likely to occur. The end result is a highly effective noise reduction method that is impervious to motion, yet, largely maintains the integrity of the detail in the image through our conservative approach in removing video compression artifacts.
Fine Detail & Edge Enhancement
Sharpness controls are not new in the world of video - nearly every TV sold in the last 20 years features a sharpness control. However, sharpening controls merely accentuate medium detail at the expense of fine detail and often add horrible "halos" around the edges and lines. While this trick was a reasonable approach for standard definition TV, when screen sizes were well under 30 inches, today's large screen TVs and HDTVs have made traditional sharpness controls highly undesirable since the damage they cause is now magnified with such larger screens. In addition, traditional sharpening controls tend to exaggerate any noise in the image by making it more pronounced so noise becomes even more pronounced when viewed on a large screen HDTV. Anchor Bay has designed Fine Detail & Edge Enhancement with large screen HDTVs in mind. Using patent pending technology, Fine Detail & Edge Enhancement is able to isolate areas of the image where hard edges are prevalent and increase fine details without adding halos or ringing. The net effect is quite extraordinary - images have more "pop" and fine detail such as blades of grass or even the pores on an actor's face are drawn out making your large screen HDTV even more enjoyable. Moreover, Mosquito Noise Reduction can be used to remove objectionable ringing and noise in the image before using Fine Detail & Edge Enhancement to draw out the fine details in the image.
Anchor Bay's 10-bit Precision Deinterlacing of standard and high definition video delivers the image quality demanded by today's large-screen, high-resolution displays. It eliminates many of the artifacts found in common deinterlacers to produce a smooth image, free of artifacts such as jagged edges and combing. Precision Deinterlacing features five-field motion-adaptive deinterlacing and edge-adaptive processing for video sources, along with advanced cadence detection for film and animation sources. All processing is performed at full 10-bit resolution to preserve all the detail and subtle nuances in the video source. Edge-adaptive processing uses an adaptive, continuous-angle detection algorithm to accurately identify and smooth image edges. Unique, "any-cadence" processing automatically locks to the wide variety of film and animation cadences found in current video sources, including non-standard cadences, and will track right through many types of "bad edits" and cadence changes. Precision Deinterlacing also features Game Mode with low-latency processing for maximum "playability".
Precision Video Scaling
Anchor Bay's latest 10-bit Precision Video Scaling technology is based on Anchor Bay's proprietary video scaling engine that can independently scale an image horizontally and vertically to achieve an outstanding picture quality for today's high resolution video displays. The scaling engine is completely flexible, accepting standard definition (480p, 576p) and high definition (720p, 1080i and 1080p) inputs and outputting the most popular resolutions from VGA (640x480) to 1080p (1920x1080). Since the scaling engine is completely flexible, other image manipulation features are also supported including zoom and pan. Non-linear stretch or panorama mode is also supported for 4:3 images that need to fill 16:9 displays without showing borders.
PReP, Progressive ReProcessing
Anchor Bay's Progressive ReProcessing (PReP) is the video processing industry's first processing method that significantly improves progressive video signals and removes artifacts caused by inferior interlaced-to-progressive conversion.
Video signals that originate in an interlaced format are often degraded by artifacts incurred when the signal is converted from interlaced to progressive formats by general purpose chips in DVD players, AV receivers, and set-top boxes. Until now, there has been no way to improve these signals to optimize images on high-resolution displays. Poor interlaced-to-progressive conversion is especially problematic with large-screen HDTVs, as upscaling to higher resolutions often amplifies artifacts created in the conversion process, making them more noticeable.
As a solution to this problem, Anchor Bay introduces PReP, an advanced video processing technology that reverts the progressive video signal output from source equipment to its original interlaced format. PReP then converts the interlaced signal to progressive format, this time applying the source, edge, and motion adaptive algorithms in its Precision Deinterlacing technology to eliminate jaggies, combing, and other degrading effects. In iScan Duo, PReP technology allows 480p, 576p, 1080p50 and 1080p60 formats to be processed by this method.
Progressive Cadence Detection
Film-based content, which originated at 24 frames per second, is broadcast at 50 or 60Hz. Anchor Bay's Progressive Cadence Detection can lock on to the original 3:2 cadence in the broadcast, reacquiring the original 24 frames per second. This signal can then be output at a source-locked 24Hz eliminating the judder that existed in the original broadcast signal. Progressive Cadence Detection can be used with 480p, 576p, 720p50, 720p60 1080p50, 1080p60 input signals.
Anchor Bay's RightRate technology converts the input frame rate to the optimal display frame rate without causing 'tearing' in the output frame. Anchor Bay's high performance frame rate conversion also supports converting film sources from 24 frames per second to 60 frames per second for NTSC format and from 25 frames per second to 50 frames per second for PAL/SECAM format.
Anchor Bay's AutoCUE-C technology automatically detects and removes chroma artifacts that are caused by incorrect upsampling of the chroma (color) signals by MPEG decoders in DVD players and satellite receivers. These artifacts are especially noticeable as horizontal streaks in images with highly saturated colors. When the artifacts are removed, the resulting picture quality is significantly improved, providing a much clearer and true-to-life image.
Precision AV Lipsync
Anchor Bay's Precision AV LipSync technology is designed to automatically delay the audio signal to match the video processing delay in other Anchor Bay products. As a result, the AV Lipsync problem that is caused by video processing delay is eliminated. If required, the audio delay can also be further adjusted to correct any AV Lipsync problem that may be already be present in the AV source.
Q: What is 'Game Mode'?
A: This mode can reduce the amount of video delay to less than a single frame. In many competitive processors the effects of applying complex algorithms to the video image results in upwards of a seven frame delay. This can inhibit the real-time performance for gamers who want instantaneous response to react to stimuli and to realize peak performance from their application. The VRS Precision Deinterlacing Game Mode will reduce frame delay down to slightly less than one frame of video.
Q: What signals can the iScan Duo output?
A: iScan Duo has two HDMI 1.3 audio/video outputs to allow connection to two displays, for e.g. an LCD TV and a projector without requiring an HDMI splitter. The third HDMI output only carries audio, with blank 720p video, which is intended to carry audio to a connected Audio/Video Receiver. If your source has a DVI output (and no HDMI output), a DVI-to-HDMI adapter or cable will be needed to connect this source to the iScan Duo. The same is true, if your display does not have an HDMI input, but does have a DVI input. DVI does not carry audio, so for DVI sources/displays an alternative method of connecting audio must be used. iScan Duo can automatically determine and output the preferred' format of the display by reading the EDID of the connected display. Some displays do not report the correct information in which case, the user can select one of the available output formats including 480p, 576p, 720p50/60, 1080i50/60, 1080p24/25/50/60,VGA,SVGA,XGA,SXGA@60Hz.
Q: Tell me more about the HDMI connections on iScan Duo
A: There are eight HDMI 1.3 inputs on iScan Duo. The HDMI inputs on iScan Duo can process 480i/p-60, 576i/p-50, 720p-50/60, 1080i-50/60, 1080p-24/25/50/60 and VGA/SVGA/XGA/SXGA@60Hz. The HDMI input and output connectors on the iScan Duo are backwards compatible with DVI-D inputs and outputs when used with an HDMI-to-DVI adapter or cable. Please note that DVI is a video-only connection that does not carry audio so an alternative method of connecting audio must be used.
Note that if you have an HDCP source and a non-HDCP display, you will probably not get a picture, whether or not you use iScan Duo.
Q: What kind of aspect ratio control does the iScan Duo offer?
A: iScan Duo has 4 predefined input aspect ratio settings:
4:3 Full Frame: to watch 4:3 content while preserving the aspect ratio
4:3 Letterbox: to watch 4:3 Letterbox, non-anamorphic, content full screen with no geometric distortion on a 16:9 display.
4:3 Non-Linear Stretch (Panorama): to watch 4:3 content stretched to fill a 16:9 display. In this mode, the image is distorted such that most of the stretching occurs at the side of the image, not the center.
16:9 Full Frame: to watch 16:9 anamorphic content while preserving the aspect ratio. This mode can also be used to watch 4:3 content on a 16:9 screen, although the image will be stretched horizontally
You may also control the size and position of the input image on your display with the Stretch and Shift buttons on the remote control or with the on-screen menu. If you would like to zoom in on the image to remove the small black letterbox bars found with a 1.85:1 source on a 16:9 display for example , then you can simply do this with the Zoom Up and Zoom Down buttons on the remote control or with the on-screen menu.
Q: What audio formats can the iScan Duo support?
A: iScan Duo has five audio outputs: the two HDMI audio/video outputs, the dedicated HDMI 1.3 audio only output, the optical digital output and the coaxial digital output. If a source connected using HDMI is outputting high bit-rate audio, Dolby TrueHD or DTS Master Audio, and iScan Duo is connected to an AV Receiver or Processor that supports these formats they will be passed through with the proper amount of delay to be in sync with the processed video. If the optical output is used with a source that supports high bit-rate audio, iScan Duo will communicate with the source to output an audio format that the optical connection is capable of carrying, stereo PCM or Dolby Digital/DTS. Audio that is input via the analog inputs can be output over HDMI or optical. There are some HDMI sources that do not output the correct audio signal when connected to an HDMI repeater, like an AV receiver or video processor. In these instances, we recommend that use an alternative method of sending audio, like the optical or coaxial digital audio outputs.
The audio section of iScan Duo supports S/PDIF and PCM formatted audio with sample rates ranging from 24kHz to 192kHz. It will likely handle sample rates beyond this range, but is only guaranteed to support sample rates within this range. The iScan Duo will pass digital audio having any bit-depth resolution up to 24 bits, at all supported sample rates.
iScan Duo will also pass compressed digital audio (e.g. Dolby Digital or DTS) provided the audio bitstream has been properly formatted for S/PDIF (IEC60958 or EIAJ-CP1201 standard) transmission by the digital audio source (according to international standard IEC61937). The iScan Duo does not alter the sample rate, format, or content of the digital audio whatsoever; it merely inserts a programmable delay into the transmission path.
The iScan Duo will also pass-through SACD (DSD) signals through HDMI.
Users should take care to use proper digital audio cables in order to guarantee valid audio reception and re-transmission. Both coax and optical cables should have high-quality, positive mating connectors at both ends. Coax cables should have a 75-ohm characteristic impedance. The use of couplers or other types of adapters to extend the digital audio cabling is not recommended.
Q: Tell me more about the lipsync correction on iScan Duo
A: iScan Duo has 4 discrete digital audio inputs (3 optical and 1 coaxial) and 2 analog audio inputs (L/R) each of which can be assigned to any of the video inputs. The HDMI 1.3 inputs can also accept audio, if the video signal is on the same input. iScan Duo is also compatible with high bit-rate audio, like Dolby TrueHD and DTS-Master Audio. If the incoming HDMI signal has HDCP, then iScan Duo cannot output this audio using the optical or coaxial digital outputs, only the HDMI output. When you switch to a particular video input, then the audio input which has been user-assigned to that video input will also be selected. For example, when you switch to Video, then the audio input which has been user-assigned to Video will also be selected.
The digital audio outputs provide a delay which matches the video processing delay of iScan Duo. Note that this delay will vary depending on the current configuration and processing mode of iScan Duo. 50 Hz sources will require a different amount of delay than 60 Hz sources, and frame rate conversion requires more delay than no frame rate conversion. The correct audio delay for all inputs is set automatically, so you need to do nothing extra to match audio and video delays. In addition, there is a user-adjustable delay which can be added or subtracted on top of the automatically set delay for problem sources. Anchor Bay's digital audio technology is called "Precision AV Lipsync". The iScan Duo also supports the DSD audio format on HDMI.
Q: Does iScan Duo have an On Screen Display (OSD)?
A: Yes, there is a very intuitive OSD that allows you to control all of the major parameters: output resolution, aspect ratio, picture controls, and audio delay. There are hints available with all controls to assist inexperienced users.
Q: How does iScan Duo detect incoming signals?
A: iScan Duo has been designed to detect which of the fifteen possible input devices is turned on and is generating an active signal, and then to automatically switch to that input. With this capability, you can switch inputs simply by turning one input device on or by turning another device off. iScan Duo also includes an "Input Priority" option which specifies which of the inputs to use when they are multiple active inputs.
Q: What kind of power supply does iScan Duo have?
A: The iScan Duo comes with a universal 12VDC @ 5A AC to DC external power adapter, which accepts 100-240 VAC at 50/60Hz.
Q: Will the iScan Duo improve the picture quality of standard definition channels from my satellite or cable system?
A: Picture improvement of heavily compressed standard, and even high, definition satellite channels is often very subjective, and depends to a great deal on exactly which aspects of the image are objectionable. The iScan Duo does incorporate three new technologies that do specifically address this issue: Mosquito Noise Reduction, Fine Detail Enhancement and Edge Enhancement. One artifact of compression is mosquito noise. This kind of compression noise is apparent along the edges of compressed images, especially text. Anchor Bay's Mosquito Noise Reduction can significantly reduce this noise providing an appreciably better picture. Additionally, Anchor Bay's Fine Detail Enhancement can extract fine details in the image that were masked by this compression. Finally, Anchor Bay's Edge Enhancement can improve the perceived sharpness of the image without adding additional ringing.
Q: What does the color of the Status LED on iScan Duo mean?
A: iScan Duo power LED color table:
No LED = Standby Mode or Front Panel Brightness set to 0
Red/Solid = No Signal Received
Green/Solid = Unknown/Unsupported Signal Received
Blue/Solid = The iScan Duo is processing the input
Blue/Blinking = The iScan Duo is processing the HDCP input signal but the display is not HDCP compliant (DVI or Analog)
