The SiI 504 is a high-quality digital video format converter used to convert any standard-

definition interlaced video signal to a non-interlaced signal. This progressive output is suitable

for display on LCD or DLP panels, or on progressively scanned CRT displays. The SiI 504 is

targeted at products that require the highest quality deinterlacing available and is particularly

well suited for progressive-scan DVD players, set-top boxes, high-definition TVs, A/V monitors

and video projectors.

The deinterlacer in the SiI 504 performs the involved process of generating progressive

frames from the NTSC, PAL or SECAM interlaced video input. Advanced motion-adaptive and

source-adaptive techniques create an output image of incredible detail without introducing

the motion and interlacing artifacts commonly associated with other interlace to progressive

scan converters. Proprietary diagonal processing, transition management and post-processing

technologies are designed to deal well with everything from clean, flawless video sources to

worst-case, noisy, unstable sources.

The output from the deinterlacer can be in either RGB or YCbCr format. A three-channel,

10-bit color lookup table can be used for changing output brightness, contrast, gamma,

hue or color temperature. A very flexible programmable video timing generator produces

all video-timing (sync, blanking, etc.), providing support for unusual display requirements.
