High-definition PCI-E broadcast audio and video VGA signal acquisition card test environment:
◆ System ----windows xp SP3
◆CPU----Intel® Pentium® Dual E2180 @ 2.00GHz
◆ Memory ----2.01GHz,0.99GB Audio/Video VGA Signal Capture Card is suitable for professional audio/video and image analysis and processing work, which can be widely used in microscopic imaging, medical imaging, intelligent transportation, analysis and measurement, biomedicine, machine vision, industrial graphic analysis, as well as a variety of other high-precision image processing and analysis fields.
The high-definition high-precision VGA signal acquisition card can be applied to industrial testing, industrial measurement, intelligent transportation, medical imaging, industrial monitoring, instrumentation, machine vision, webcasting, recording and broadcasting systems, VOD on demand, remote education and training, security monitoring, traffic tolls, image acquisition and a variety of other image acquisition, processing and analysis, video conferencing systems and to provide free network and telephone Technical support guidance and maintenance.
One, screen monitoring
If you want to use video capture hardware to monitor the content of a display, - for example, in the field of industrial automation, you can use a VGA capture card or capture box to capture the content of this display, real-time transmission to the monitor, but also can be saved for viewing after the fact.
Two, screencasting
A, live video conferencing screen, to more people who do not have the opportunity to participate in video conferencing (camera + video capture card + interactive whiteboard / TV or rear projection) to watch;
B, the use of VGA capture card or capture box to do screencasting, a lot of clearer than the other ways of live picture.
C, the field of teaching, can be used to live teachers computer screen, with teaching whiteboard, to achieve multimedia teaching, or distance learning;
Three, dealing with special video formats
With the VGA capture card or capture box with the streaming media encoding software, real-time capture, encoding into streaming media format, put on a streaming media server for on-demand playback. Some video files, the file format is self-defined by the development company, other company software can not directly on its processing, such as teaching courseware, 3D animation files, and so on. These video files are too large for carrying, transmission, demonstration, such as 3D animation files, then you can use the VGA capture card or capture box with the video editing software such as Audio/Video BaoDian, Acoustic Studio X2, encoded into a very small streaming media format with a VGA capture card or capture box will be captured into an uncompressed file in the form of AVI, for editing.
Four, security X-ray machine, radar image signal, VDR recorder, medical X-ray machine, CT machine, gastrointestinal machine, electronic endoscopy, etc.
Five, VGA cameras, VGA cameras and other VGA signals, RGB signals output device image acquisition and processing
1, educational courseware recording, multimedia recording video, conference recording, video conferencing. Remote education training;
2, large screen splicing, TV wall industry, virtual studio, virtual reality, industrial control, game consoles and other equipment;
3, security X-ray machine, radar image signals, VDR recorder;
4, medical X-ray machines, CT machines, gastrointestinal machines, colposcopes, etc.; VGA high-definition capture card works by the RGB analog signals through the A/D sampling converted to digital. / D sampling is converted to digital signals, through the FPGA written into the SDRAM as a cache, and then by the FPGA from the SDRAM will be captured in the compressed data read out through the PCI bus to the host computer, the host computer to the data transmission and other processing.
After the high-speed PCI bus can directly capture the image to the VGA memory or host system memory, in addition not only can make the image directly captured to the VGA, the realization of a single-screen mode of operation, but also can take advantage of the expandability of the PC memory, to achieve the required number of sequences of continuous frame-by-frame acquisition of the sequence of images, sequence of images for processing and analysis. If a PC VGA data on another PC to display as well as the acquisition of VGA signals, the traditional method is to turn the VGA signal into a video signal through the video converter VGA-VIDEO, and then through the video capture card on another PC to display the acquisition.
VGA high-definition capture card can directly capture VGA signals, you can input the VGA video signal real-time capture and compression, and can immediately display on a monitor at the same time another or even multiple devices VGA data, without adding additional equipment.
