both on the left. One of the input terminals is selected, and the signal enters and
is sent to a 16 Megabit S-DRAM memory. The signal plays out of memory at a
fixed time delay that is determined by the user. Both data writing points and data
reading points are controlled within the IC using read and write pointers in the
control section. All told, there are nine individual blocks in this IC (Front Left,
Front Right, Center, Surround Left, Surround Right, Subwoofer, Stereo Left,
Stereo Right and Digital Out). Because the nine blocks can be controlled
independently, you can create virtual speaker positions ideal for both Super
Audio CD and DVD playback. In addition, since all nine blocks can be controlled
simultaneously, all signals can be given the same delay to achieve A/V alignment
with the television.

High performance audio D/A converters
with DSD inputs (all models)
To elicit the full sound quality from Compact Disc, DVD-Video sound
tracks and especially from Super Audio CD, these DVD players incorporate
powerful audio D/A conversion technology. The D/A converters can handle DSD
inputs for Super Audio CD playback as well as high quality DVD-Video signals up
to 192 kHz sampling rate with 24-bit word length. This assures compatibility with
the widest range of source material.
The DVP-NS999ES offers even more, with separate Sony D/A converters
for multi-channel and stereo programming. Both of these D/A converters include
on-board Variable Coefficient digital filters for extremely accurate rendition of the
soundfield on DVD-Video and CD. In addition, on-board DSD filters reduce high-
frequency noise in Super Audio CD playback. Finally, both D/A converter ICs
employ multi-level delta-sigma D/A conversion, which assures both excellent
linearity and remarkably low noise.
Balanced outputs on the DVP-NS999ES D/A converters enable balanced
transmission of audio signals to the post Low Pass Filter on the audio circuit
