high-definition streaming audio and video VGA capture card
The high-definition streaming audio and video VGA capture card adopts a high-speed PCI-E 1x slot interface, making the transmission speed faster and more stable than PCI. The board realizes 1-way VGA high-definition signal (can capture high-resolution line by line (can reach 1920 x 1440), 2 CVBS Video signal inputs (supports PAL and NTSC video formats), and one stereo audio signal input (can be combined with any video signal). And it can capture at the same time, supports multiple cards in one machine, and can also be used with other video capture cards. Using 256MB/64bit DDR2 memory chip as image cache, its storage bandwidth reaches 2GB/s, making the captured video smoother, clearer and more stable.
This high-definition streaming media capture card uses soft compression to compress video, but its effect is better than hard compression. It uses efficient Master DMA mode and consumes less machine CPU during the entire video capture process. For system integrators and enterprise users, it also provides a complete secondary development package SDK, which supports various standard Directshow development software and can be directly installed and used, including most of the video conferencing, e-learning, P2P, monitoring and other software currently on the market.
It has two interfaces that can collect DVI signals, VGA signals, Y/Pb/Pr signals, HDMI audio and video signals, CVBS signals, S-Video signals, and can perform two high-quality collections at the same time. It is a domestic model. HD dual-channel capture card. Video resolutions are automatically recognized and automatically displayed from 40 x 30 to 2048 x 1536 pixels.
The high-definition dual-channel capture card uses a 10-bit sampling precision AD converter to ensure rich picture details, high signal-to-noise ratio, and minimize the appearance of color fringing. At the same time, the 5-Tap scaling and motion adaptive de-interlacing technology implemented in the FPGA further ensures image quality. The compatibility is also very good, compatible with DirectShow/DirectSound API under Windows and V4L2/ALSA API under Linux, and compatible with a large number of existing audio and video processing software.
