Mediamatics NDV8501
DVD on a Chip Processor
General Description
Platform
The MediamaticsTM 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.
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
Audio
IEC958/1937 output is standard for the NDV8501.
The NDV8501 provides unsurpassed audio processing
quality and flexibility with wide ranging support for all
Features
The NDV8501 is a 2nd 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.
