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-effective 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
