Model 616 is a PCI
frame grabber that captures and transfers full-frame (640 x 480)
video at 30 frames per second. It uses hardware compression to
produce encoded MPEG-2 and MPEG-1 data streams of 100 kbits to 10
Mbits per second. It also has two audio input channels that are
synchronized to the MPEG data.
MPEG2 data reduces the
amount of memory required to store full motion video. The compressed
data requires a smaller transmission bandwidth. This makes it
possible to transmit 30 frames/sec video over a 10/100 Base-T
Ethernet. The hardware compression circuit uses a motion
estimation algorithm to produce smooth images from interlaced
cameras. The length of MPEG2 video streams is not limited by
the viewing software.
Digitized video and
audio inputs can be looped back to the output circuits to allow
camera and sound adjustments. The 616's video D/A can be
programmed to generate color test bars. This is useful for testing
the video output channel.
The 616 is supplied with
drivers for Linux that allow register and memory buffer
initialization, reading and writing MPEG2 data. The driver
synchronizes the audio channel with the MPEG2 video channel during
recording and playback.
Linux players are included with the SDK. They allow
simultaneous viewing and recording of the video
