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.
