Sensoray of Tigard, Ore., releases the Model 810, PCI Express four-channel frame grabber with audio capture, which simultaneously takes four channels of analog NTSC/PAL video and four channels of stereo audio, according to the company.
The product captures raw video frames from each channel at up to full frame rate, resulting in an aggregate frame capture rate of up to 120 frames per second (fps) for NTSC and 100 fps for PAL. Four BNC connectors are available on the board’s mounting bracket for connecting external composite video sources. A DB15 connector on the same bracket is used for the audio inputs. A 34-pin header provides an alternative convenient access to all I/O signals on the board.
The unit supports a wide range of video capture resolutions, including D1, VGA, QVGA, QQVGA, SIF, 2SIF, 4SIF, CIF, QCIF, SQCIF and 4CIF. The audio can be stereo or mono, and the sampling rate supports 32kHz, 44.1kHz, and 48kHz. Embedded data may be added to each frame during the vertical blanking interval (VBI).
