In today's high-definition era, high-definition VGA \ DVI capture cards are favored by enterprises and project managers. But generally high-definition capture cards are expensive. So, how to choose a cost-effective HD VGA \ DVI capture card for your project application is a very important thing. The following Microvision will be aimed at different industries, and will explain the application of high-definition capture cards in specific engineering projects in terms of signal source types, points of practical application of capture cards, and other issues.
Different industries use different video equipment and have different requirements for video quality.
1. Large screen, TV wall industry applications
In large-screen splicing applications, the most important issue is the diversity of video sources. For example, commonly used are: VGA (notebook, desktop, graphics workstation), Video (camera, DVD) and DVI, SDI (broadcast signal source) HD, SDI and so on. Different types of signal sources need to use different acquisition cards. The compatibility of these standard acquisition cards and non-standard acquisition cards on the same computer is very important, and the video image standard and non-standard acquisition cards have very different aspects in this regard. Good compatibility.
2.High-definition medical solutions
With the popularization of high definition in the medical industry, many system vendors have begun to consider using high definition solutions. The most important thing for medical signal acquisition is real-time and authenticity. Wei Shi image M2000E black and white capture card and MV-VGA series color cards are based on Microsoft's Directshow architecture and a high-definition capture card with a powerful SDK secondary development kit, compatible with any medical equipment software. The collected signal has strong real-time, real and clear picture, and has the function of text and time overlay setting, which is convenient to record the situation and date of each acquisition.
3. Educational recording and broadcasting system solutions
In the video acquisition solution of the education recording and broadcasting system, most manufacturers have adopted digital cameras, but due to the high price of digital cameras, there is still a certain market for analog signal acquisition. HD cameras are applied in the field of fine courseware recording, and the audio and video are fully synchronized. By supporting third-party software based on Microsoft Directshow architecture, teachers can demonstrate computer screens for teaching demonstrations, student Q & A videos, and other real-time recording into standard stream media formats required by fine courses and upload to Any server in the school can be synchronized to live broadcast or on-demand on the campus network or the Internet to realize the role of remote interactive teaching or campus class communication. Wei Shi image VGA series high-definition VGA / DVI capture card has excellent performance in classroom demonstration and live video capture, is an excellent choice for the majority of education recording and broadcasting system integrators to build a system
4.Multimedia HD video capture solution
Wei Shi image VGA series VGA \ DVI capture card support based on Microsoft Directshow framework, you can use windows media encoder or real encoder to record into your favorite multiple streaming media formats and upload to the Internet. In addition, Wei Shi image VGA series capture card captures standard definition, high definition, full high definition signals, and can do other secondary development through the built-in SDK development kit.
5. Network video conference and training system solutions
With the vigorous development of video conferencing, network video conferencing is favored by the majority of enterprises as the most convenient and efficient meeting method in video conferencing systems. As a result, corporate users have put forward higher requirements for the image quality of video conferences. Video capture cards are more versatile than USB cameras, so more and more business users are now using video capture cards.
Vision-Image's MV-VGA series of high-definition VGA \ DVI capture cards intelligently match the signal source. The front-end signal source changes, and the back-end capture card automatically adapts, eliminating the tedious process of manual adjustment. And can capture 1080P or 1080I full HD signals and record into the required video format, to achieve remote zero distance communication. In addition to the applications in the above industries, the video capture card series is also widely used in high-definition security, transportation security, military simulation, virtual reality, and so on.
