divio
remains on the cutting-edge of digital video technology with
the NW802, the industry's first single-chip PC Camera engine. The
NW802 enables a new class of low-cost, high-performance USB-based
PC Cameras. Leveraging
divio's
patented JPEG-lite technology, the
NW802 provides real-time, full-motion digital video capture across a
standard USB interface.
divio's
dynamic-bit-rate control automatically
adjusts the camera's video compression rate to guarantee the highest
video performance under any given bandwidth conditions. Next-
generation PC Cameras powered by the NW802 make possible new
applications including video capture, video e-mail, video conferencing,
and still image capture at affordable prices.
The NW802 replaces the complex, costly chip sets used in current PC
Camera designs. The NW802's fully integrated design integrates a
number of functions into a single-chip - JPEG-lite
TM
encoder, image
processing, auto-exposure, timing and sync generator, USB interface,
and support for off-the-shelf CCD sensors.
To simplify implementation and reduce time to market, a PC Camera
manufacturing kit with full functionality is also available. The kit
includes all of the hardware, software and documentation necessary
to quickly and easily develop low-cost, high-performance PC
camera designs.
divio
is leading the way to superior digital video on the PC at an
affordable price.
