The LT-102-PCIe

PCI Express Media Acquisition and Compression Board

The LT-102-PCIE is an HD video capture board that can compress HDTV video in real-time without using the host computer’s CPU resources. The product is installed in an available PCI Express slot on your host system.

This board captures video from both analog and digital HD and SD video sources via DVI, RGB, VGA, component, S-video, or composite connectors. In addition to external video sources, the LT-102-PCIE can compress from host internal video sources such as files or DirectShow devices including USB and Firewire cameras. An HD/SD-SDI option is available.

LT-102-PCIeThe LT-102-PCIE compresses video in compliance with the H.264/VC-1 standard also referred to as WMV-HD. This codec was originally developed by Microsoft, this format is supported natively by most software decoders. Audio is compressed via the WMA codec.

This powerful board can compress 1080p/i at up to 30 frames per second (fps). 2048×2048 can be encoded at 15fps. At lower resolutions the maximum compression frame rate increases. If the frame rate is higher than the board can handle, frame decimation can be enabled allowing high frame rate source to be acquired at a lower frame rate.

Compressed bitrates can vary between 64Kbit/s and 80Mbit/s depending on resolution, frame rate and quality desired. An uncompressed video capture function is also available for snapshots or continuous raw video acquisition.
