MV-VGA420E dual-channel VGA image acquisition card is a comprehensive new-generation PCI-based application based on market-oriented, large-screen edge fusion, streaming media, multimedia recording and broadcasting systems, medical and scientific research, and detection. EX4 bus as a data access channel, the maximum transmission speed of 480MByte / s dual-channel high-speed VGA interface high-end image acquisition card, in addition to the PCI-EX1 interface acquisition card image restoration is more realistic, color quality is more delicate, transition level Better, wider acquisition range, smaller image detail loss, etc. External 1920*1200 resolution can achieve 30FPS at the same time, with high frame rate, smooth picture, and relatively low cost compared to DVI dual interface. The product can collect VGA signals output from graphics devices such as PC graphics cards, and can also collect image signals such as non-standard progressive RGB components, suitable for high-precision, high-resolution image acquisition, HD VGA video image storage, encoding transmission, etc. Claim.
If you need to capture screens from other data sources, such as Windows, Linux, UNIX or MAC computers, embedded systems, medical devices, game consoles and other scientific lab equipment, VGA/RGB data streams continue to receive, traditional The method is to lead the analog VGA signal to a specified screen display, which of course means wasting resources and taking up more space.
Or use a converter to convert RGB signals, digitally compress, archive or transfer from a computer to an NTSC or PAL video signal. Due to the inherent error of the digitization of the video signal and the low resolution of the analog video signal, the problem can be solved but the conversion quality is poor. (The 1024x768 RGB image is mapped to a 768x576 video image with a large error.)
To achieve full resolution, high quality image or video streaming, the correct solution is to use the MV-VGA420E for acquisition. Display VGA data of another device simultaneously on one display without adding additional devices. With this hardware, it will be possible to obtain fully resolved RGB images (XGA, SXGAUXGA or other custom signals), or various file formats such as BMP, JPG, AVI video formats and real-time streaming of LAN or WAN. Since the image is not lost by NTSC or PAL conversion, the image quality is higher.

MV-DVI420E dual-channel DVI/HDMI image acquisition card is the comprehensive technology application of WeisVision. It is based on market orientation and is the latest in the field of large-screen edge fusion, streaming media, multimedia recording and broadcasting system, large-screen splicing, medical and scientific research and testing. The new generation is based on PCI-EX4 bus as the data access channel, the maximum transmission speed reaches 480MByte/s dual-channel high-speed DVI/HDMI interface high-end image acquisition card, in addition to the PCI-EX1 interface capture card image restoration is more realistic, color painting The quality is more delicate, the transition level is better, the collection range is wider, the image detail loss is smaller, etc. The external 1920*1200 resolution can achieve 30FPS at the same time, with high frame rate, smooth picture and relative VGA interface quality. Better and more remarkable, the product can collect DVI/HDMI signals output from graphics devices such as PC graphics cards, and can also acquire image signals such as non-standard progressive RGB components, suitable for high-precision, high-resolution image acquisition, HD DVI. /HDMII video image storage, encoding transmission and other requirements.
The MV-DVI420EDVI capture card is a plug-in PCI-Ex4 single card that captures signals (RGB or DVI) from a source of playback output and displays it as a standalone application on your Windows?? desktop. These processes are done in real time, allowing you to view data from PCs, MACs, industrial or medical devices, cameras and other video devices. The MV-DVI420E has two DVI (compatible with HDMIVGA) type of interface that can directly supply two independent data sources to your PC.
The MV-DVI420 EDVI capture card captures the simulated RGB/VGA data and stores it on an onboard video buffer. These data are then copied to the host system using DirectMemory Access (DMA) for display, storage or streaming.
If you use a Microvision image card, the MV-DVI420E will transfer data directly to the image card to improve device performance. The MV-DVI420 EDVI capture card sends the corresponding portion of each captured image to each display channel and directs each channel to restore data using its own graphics engine. Fully use hardware to significantly improve performance.
When RGB/VGA data is displayed on a non-MV-DVI420E graphics card, the MV-DVI420EDVI capture card will send the data to the system memory or directly to the graphics card depending on the display software used.
The MV-DVI420EDVI capture card also provides you with a DirectShow-compatible WDM stream driver, activates the application software that supports the DirectShow interface, and uses the card as a capture device. Many softwares are compatible with the MV-DVI420E card, such as WindowsMediaEncoder??, and many other DirectShow applications offer more options for your acquisition and streaming.
MV-DVI420E has two DVI to VGA interfaces
