Sensoray Model 811 is a PCI Express board that simultaneously captures four channels of analog NTSC/PAL video and four channels of stereo audio. It captures raw video frames from each channel at up to full frame rate, resulting in an aggregate frame capture rate of up to 120 fps for NTSC and 100 fps for PAL. The 811's high frame capture rate, coupled with its high performance bus interface, makes it well-suited for applications that require multi-channel audio/video capturing in a compact form factor.

The board implements a single-lane (x1) PCI Express interface that enables it to be plugged into a PCI Express slot of any width. All operating power is obtained from the PCI Express bus; no external power supply is needed

Features:

• 4 composite/S-Video + 4 stereo audio input channels
• Simultaneously captures on all 4 channels
• Captures raw RGB/YUV video or frames
• VBI support
• 4 digital I/Os configurable as inputs or outputs

Specifications:

• System Requirements: Due to the extremely high data rates involved, a computer with sufficient bandwidth and processing power is required to ensure error-free processing of the video streams produced by Model 811. Sensoray has tested Model 811 with a cross-section of computers to help you determine whether your system will support these high data rates. For details see 811 Performance Benchmarks.

Maximum Frame Rate

Sensoray bundles industry standard drivers with Model 811 for both Linux and Windows. The Linux driver is a high performance driver that makes possible simultaneous full frame rate capture at D1 resolution from all four input channels. The Windows driver, which is a closed source product of Trident Microsystems, has lower performance that may require tradeoffs between the number of active channels, resolution, and frame rate.

The following table shows the maximum frames per second that will reliably result in error-free performance on a typical host computer. In most cases these performance levels will be enhanced when using higher performance host computers.
