Component Video Upconversion
As the nerve center of modern home entertainment, the A/V receiver
needs to handle the full range of audio/video sources, including everything from
HDTV receivers, digital satellite receivers and DVD recorders to VHS decks and
videogames. Along with the range of sources comes a range of potential video
input types: from the relatively low-grade composite video to S-Video, component
video and HD component video. Ideally, all of these signals should be conveyed
to the television with the highest possible quality. And for the sake of
convenience alone, all of these signals should be conveyed to the same input of
the television. That's why the STR-DA3000ES, DA5000ES and DA9000ES
upconvert Composite Video to S-Video as well as upconverting S-Video to
Component Video. Through these upconversions, Sony provides a high-quality
connection to the television, while simultaneously reducing the need to switch
input sources at the television.
These upconversions are made possible by two Sony large-scale
integrated circuits (LSIs), which draw on years of Sony IC experience. Sony's
CXD2064 digital LSI performs Composite to S-Video upconversion, while the
analog CXA2199 upconverts S-Video to Component Video. Some previous
upconversion circuits could not control the Hue, Contrast and Brightness of
converted signals. But thanks to the CXA2199, Sony receivers give you these
capabilities.

On the right Sony's CXA2199, upconverts S-Video to Component Video.
Together, the circuits ensure high-quality connections to your
television—and simplify system operation.
DVI Interface (STR-DA9000ES)
The STR-DA9000ES can accommodate the latest digital video sources
with two digital inputs and one output. The Digital Visual Interface (DVI) enables
spectacular, uncompressed digital-to-digital transport of a High Definition video
