different software applications to access many different image input
devices. TWAIN compliance is needed for both software
applications and imaging hardware devices (scanners, cameras) to
be compatible.
USB port -
USB is the abbreviation for
Universal Serial
Interface
, and is a new interface with throughput goes up to
12Mbps. It allows daisy -chained of 127 PC peripherals connection
with 5 meters per device. USB provides the power for each device,
means no more external power adapter for PC peripheral.
USB also supports hot swap of device, or dynamic
insertion-removal, and auto configuration as device changes. The
throughput of USB, however, is not sufficient for real-time video
transmission. The recently released USB PC camera, imbeds video
compress/decompress technology to increase the data transmission
and supports 30 fps in QCIF or CIF format.

little with PC camera and other hardware without application
software. Microsoft bundles NetMeeting in Windows98 providing
basic solution for video conferencing over Internet or Intranet.

pattern recognition, personal security and remote monitoring
utilities to touch down specific arena. Some software is quite
sophisticated with comprehensive user interface, check you’re
