iScan Ultra
Video Processing System

Introducing the iScan UltraTM, the latest addition to the acclaimed iScan family of video processing systems. The iScan Ultra builds on the performance of the highly rated iScan ProTM, extending functionality to provide the complete video solution for today's home theater.

The iScan Ultra's award-winning PureProgressiveTM video processing capabilities include:

State-of-the-art deinterlacing and line doubling for dramatically improved rendering of standard-definition video on digital televisions (DTVs) and projectors. Motion-adaptive deinterlacing and source adaptive processing of NTSC, PAL or SECAM video provides near high-definition (HD) video performance from standard-definition sources such as DVD players, VCRs and set-top boxes.

Video Switching between seven inputs, including dual composite, S-Video and component inputs, plus a pass-thru input for high-definition video, progressive video or computer video formats.

Precise Picture Control, with separate settings stored for each input, including brightness, contrast, saturation, hue, Y/C delay, sharpness (edge enhance, fine detail) and a chroma filter for removing MPEG-decoder chroma artifacts.

High Quality Scaling for full aspect ratio control, enabling a 4:3 letterbox format to fill the screen of a 16:9 widescreen display.

Digital Visual Interface (DVI) output, offering the highest digital video quality for the growing number of DTVs and projectors supporting DVI inputs, without suffering the losses associated with an analog interface.

The iScan Ultra bridges the gap between the array of existing standard-definition video sources and the performance of today's DTVs and projectors, providing a seamless system solution for a quality home theater experience.

iScan - Compatible Devices

Silicon Image's iScan digital video processing products are compatible with a wide range of DTVs, projectors and progressive scan displays, such as plasma and LCD panels.

The iScan converts NTSC (480i) broadcast format to a 480p format, and PAL/SECAM formats to a 576p format. NTSC is used in North America and countries with 60Hz AC power. PAL is used in Europe (excluding France), China, and countries with 50Hz AC power. SECAM is similar to PAL and is used in France.

Please note that displays limited to a standard NTSC, Pal or SECAM interlaced signal (and not able to support a progressive video output), will not function with iScan products. To determine if your display is compatible with the iScan product family, please compare the following iScan output timings with your display's specifications:

480p: 720 x 480, 60Hz refresh, 31.5KHz Horizontal scan rate

576p: 720 x 576, 50Hz refresh, 31.25KHz Horizontal scan rate

The iScan Pro can output either RGB or YPbPr color formats. The iScan Ultra also supports RGB and YPbPr outputs, as well as the DVI (Digital Visual Interface) for an uncompressed all-digital output.

If your display supports the above timing it should be compatible with iScan products. For a listing of products tested for iScan compatibility, please click on the links below.

Direct View Televisions

Direct View is the formal name for a normal "tube" TV. They are based on large CRTs (cathode ray tubes) that project the image onto a the surface of a phosphor-lined glass screen which you view directly, hence the name. Some other devices, such as projectors may also use CRTs but they project the image onto a separate screen. Direct View sets, if they are capable of accepting a 31.5kHz progressive signal, are typically much improved with an iScan. Some of these sets may have their own internal line doubler or "upconverter" which is used to convert the incoming 15.75kHz (normal) signal to 31.5kHz (or higher). The advantage of an iScan in these cases is that it does a much better job of this upconversion than any of the current generation of embedded line doublers.


Projectors fall into two categories, those that project the image onto the front (viewed) surface of a reflective screen and those that project onto the rear surface of a translucent screen. Both types can be based on CRTs, LCDs (liquid crystal displays), DMDs (digital micromirror device from Texas Instruments, also known as DLP) or some other technology. Of all of these, CRTs are the most improved with a line doubler. The effect on LCD and DMD projectors greatly depends on the make and model of the projector - with some there is a dramatic improvement, with others it is not as dramatic.

Flat Panel Televisions

Flat Panel Televisions, typically based on plasma or LCD technology, can be thought of as inherently progressive in that the entire image is drawn at one time with no interlacing of odd and even lines. Because of this capability, most of these devices are capable of acting as computer monitors as well as being used as televisions and consequently, most can accommodate an iScan. In addition, because most of the existing flat panels have very poor line doubling built-in, the addition of an iScan can dramatically increase the quality of the video.
