The Model 2253 from Sensoray is a compact USB audio/video codec with a low power consumption well suited 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. The board 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.
Other features include two concurrent output video streams either uncompressed or at different resolutions, text overlay capability and three general-purpose digital I/O signals.
