ASIC Solution for 1-channel DVR
application using HDD
NVP3000
NVP3000 is an ASIC solution to fit for 1-Channel DVR application.
It integrates pre/post processor, M-JPEG CODEC, hard-disk controller, and
key/jog-shuttle interface.
In addition, it supports time-laps recording mode with flexible image
compression rate to save disk usage, watermark encoding, and easy
interface to most video multiplexer and CIF application.
Therefore, it provides cost-effective solution for real-time full duplex
video/audio record and play back system.
At play back mode, search, fast-forward, rewind, and pause functions
are supported.
NVP3000 also includes internal buffer to communicate with
external CPU for network application, and it supports HDD user
accessible area as well as extra pins for key and jog-shuttle interface.
