2253 is a compact USB audio/video codec.
The board's small size, 1.5x2.75 inch and low power consumption, 1.5 W, make it
useful for embedded applications. In the encoding mode model 2253 outputs an uncompressed low latency
video stream along with the compressed video stream to facilitate previewing
and real time image processing functions. Up to 80 characters of overlay text
may be added to the video.
The board can also perform as
a decoder, converting the compressed audio/video stream into standard analog
video and audio signals, to be supported in SDK Release 2 -- please download
hardware manual for list of currently supported features.
Model 2253 is powered through the USB port and
does not require any additional power supplies.
Each unit has a unique serial
number in its flash memory and on a bar coded label. The serial number can be
read using the software API.
