Sony's powerful CXD9722 handles both Speaker Time Alignment and
A/V alignment.
Incidentally, this adjustment is not duplicated on most A/V receivers.
Some receivers can adjust for speaker distance on the multi-channel signals that
are decoded in the receiver itself. But most receivers offer no such adjustment
for the 5.1-channel analog inputs you'd be using to enjoy multi-channel Super
Audio CD.
A/V Alignment (all models)
Today's advanced televisions and video projectors often incorporate
sophisticated video signal processing to optimize the image quality. Often, these
circuits require buffer memories that result in a slight delay of the video signal.
Unfortunately, this can result in a mismatch, where the television picture lags
behind the sound from the speakers by some fraction of a second. As you can
imagine, the effect can be unnatural and annoying.
That's why Sony built a second major function into the CXD9722 Digital
Signal Processor. This integrated circuit enables you to correct time
misalignments between the audio and video signals by up to 120 milliseconds, in
10 millisecond increments. This brings your television and your home theater
speakers back into alignment. This A/V alignment is performed uniformly on
stereo, 5.1 channel and even digital audio outputs.
Separate speaker settings (all models)
These DVD players also provide speaker size and location settings for
Super Audio CD playback that are separate from the settings you make for DVD-
Video and other formats.
How the CXD 9722 works (all models)
As the diagram below shows, the CXD9722 receives input signals from
either the DVD/CD Data input terminal or the Super Audio CD Data input terminal,
