Dual-channel DVI capture card Streaming video conferencing medical HD capture card

DVI capture card
  【 Product Features 】
  · Dual HD signal acquisition simultaneously.
  · The input video signal can reach 1080p/60 Hz.
  · It can collect DVI, VGA, HDMI and component signals.
  · Two analog audio signals can be collected (need to be led out by on-board wiring).
  · Can collect LPCM audio signal in HDMI.
  · Microsoft AVStream standard driver, can support most Windows multimedia video software or streaming software.
  【 Product advantage 】
  · High performance DMA transmission function.
  · Can dynamically switch input signal source type: DVI/HDMI, VGA, component.
  · Compatible with composite video (CVBS) input signals.
  · Automatic input video format detection, automatic effective video region detection, automatic VGA acquisition phase adjustment.
  · Manual setting of effective picture area function, which can be used for picture cropping and support for special input signal timing.
  · Multi-stage picture scaling function, with three zoom modes for the picture aspect ratio.
  · Support vertical filtering and motion adaptive deinterlacing.
  · Hardware color conversion, can output RGB24, RGB32, YUY2, UYVY, I420 color formats.
  · Support color adjustment function, can adjust the picture contrast, brightness, color saturation, hue, Gamma; And can separately adjust the brightness, contrast of R, G, B three colors.
  · Screen horizontal and vertical reversal function.
  【 Performance Characteristics 】
  ○ Good picture quality: The 10bit sampling accuracy AD converter is used to ensure that the picture is rich in details, the signal-to-noise ratio is high, and the appearance of color edges is minimized. At the same time, 5-Tap scaling and motion-adaptive deinterlacing technology implemented in FPGA further guarantee the picture quality.
  ○ Good sound quality: 96KHz sampling rate, 24bit sampling accuracy AD converter, measured signal to noise ratio above 90db.
  ○ Full Compatibility: Compatible with Windows DirectShow/DirectSound API, compatible with a large number of existing audio and video processing software.
  ○ High performance: Image processing such as scaling and deinterspacing that consume CPU time is completed in FPGA, which greatly reduces the burden of CPU, and the high efficiency DMA transmission mode further liberates the CPU's ability, so that the CPU can focus on the work specified by the user.
  ○ Easy upgrade: Different from ASIC, the flexibility of FPGA greatly protects the value of users' assets, and we continue to provide users with more functions and better services through Firmware/Driver upgrades.
