MediamaticsTM NDV8401
DVD on a Chip Processor
Platform
The MediamaticsTM NDV8401 DVD on a Chip Processor
provides features and cost effective system integration
for Universal DVD Players and Internet connected
Players/Recorders. Integration of an industry standard
RISC processor architecture operating at high
performance levels allows system developers to combine
the ease of C based application coding with flexible
system extensions unavailable in other platforms. This
processor can be equally applied to DVD-Video & DVD-
Audio playback and Internet Appliance products.
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.
Audio
The NDV8401 provides unsurpassed audio processing
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.
