DVD on a Chip Processor

General Description

Platform

The Mediamatics

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

enhancements are being provided on the NDV8501 device to address both full-featured DVD-Players and DVD-R/W

Recorder/Player products.
