Silicon Image I-Scan Ultra
Product Description
| 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 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
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. |
