Mediamatics^TM NDV8501
DVD on a Chip Processor
General Description
Platform
The Mediamatics^TM NDV8501 DVD on a Chip Processor
provides next generation 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, DVD recordable
solutions, Hard Disk Drive based recordable solutions
and Internet Appliance products.
Audio
The NDV8501 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 for
common DVD-Video, VideoCD and CD formats has
been carried forward from previous generation devices
and in addition, support for DVD-Audio formats, DTS,
MPEG-2 multi-channel, Dolby Prologic, HDCD and MP3
have been added. Karaoke processing and a royalty-
free 3D Stereo Surround implementation are also
provided. 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 NDV8501.
Features
The NDV8501 is a 2^nd generation “system on silicon” solution for consumer DVD Players. Significant feature
enhancements are being provided on the NDV8501 device to address both full-featured DVD-Players and DVD-R/W
Recorder/Player products.
