Audio
The NDV8401 provides unsurpassed audio processing
quality and flexibility with wide ranging support for all
common disc-based audio formats and many Internet
based formats. A custom 24-bit DSP has been
developed to provide a powerful solution for the latest
compute intensive audio algorithms. Support includes
DVD-Video, VideoCD and CD formats. The flexible
audio structure allows audio data to originate from disc-
based media, external digital audio streams or via the
Internet. Full 5.1 channel output with simultaneous 2-
channel down-mix and IEC958/1937 output is standard
for the NDV8401.
Features
The NDV8401 is a “system on silicon” solution for consumer DVD Players. Significant feature enhancements are
being provided on this version of the NDV8401 device to address both full-featured DVD-Players and DVD-R/W
Recorder/Player products.
