NW 701
DAAD™
Digital to Analog;
Analog to Digital
divio introduces the NW701, the world’s first single-chip DV codec.
Fully DV-SD “BlueBook” compliant and designed with divio’s patented
compression technology, the NW701 delivers unrivaled video quality,
performance and functionality. With a single-chip design and glueless
interface to standard video components, divio’s DV codec will replace
current multi-chip solutions and enable a new generation of cost-effec-
tive digital video products including camcorders, desktop PCs, VTRs,
and stand-alone applications. In addition to the standard 25Mb/s data
rate, the NW701 provides low bit-rate modes for video capture to a
variety of low-cost storage devices.
divio has created NW701-DAAD™ (D<—–>A; A<—–>D) manufacturing kits
with expanded functionality to simplify the implementation process and
reduce time-to-market. divio supplies all of the hardware, software and
documentation necessary to develop low-cost, high-performance
product designs.
The NW701 provides an unprecedented feature-set that delivers the
essential digital video engine to empower real-time DV performance
and quality.
