Four-channel real-time high-definition SDI audio and video capture card uses a PCI-E Software, with complete SDK secondary development package.

This video capture card can connect to 4 SDI interfaces through the PCIe slot of the host computer. It uses the PCI-E Audio input is directly compatible with standard DirectShow software. It supports multiple cards and multiple acquisition streams in one machine, and is widely used in various fields such as online video live broadcast, video conferencing, recording and broadcasting products, medical image processing, radar signal data collection, and multi-screen display.

Video capture unique DMA technology

In PCIe2.x systems, each DMA bandwidth can reach about 400MB/s. In PCIe 1.x systems, each DMA bandwidth can reach about 200MB/s. The independently designed PCIE DMA engine eliminates the need for external cache DDR chips and reduces latency. lower.

Features related to SDI signals:

Integrated cable equalizer, supported transmission distances are as follows: HD-SDI signal transmission distance up to 190 meters 3G-SDI signal transmission distance up to 150 meters, supports SHD/3Ga/3Gb/3Gb-DL/3Gb-DS Standard, supports YCbCr4:2:2 color sampling, supports 8-channel audio channels, up to 48KHz.

Video processing function

Video cropping; video scaling; video de-interlacing; video aspect ratio conversion; automatic or manual selection of input video aspect ratio; automatic or manual selection of captured video aspect ratio, video color space conversion; supports RGB, YCbCr 601, YCbCr 709, YCbCr 2020 color space, supports limited or complete quantization range, supports limited, complete and extended color gamut saturation range, video frame rate conversion.

Multiple cards and multiple acquisition streams in one machine

Supports the installation of multiple cards in the same system; the onboard DIP switch, from 0 to 3, provides 4 numbers for numbering the cards; the video and audio equipment displayed in the user software will also contain the card number.

For any input signal, any capture stream can be output; multiple processes are supported to open the same video with different capture resolutions.

Provide secondary development package SDK

Provide a complete SDK development package C++, C#, VB #xff09; to facilitate users to quickly integrate into existing systems.
