    Solution background introduction:

    With the increasing demand for high-definition video entertainment, coupled with the rapid development of network communication technology and digital storage technology, 1080P high-definition video conferences have become multimedia information such as text, documents, pictures, programs, etc., which are not limited by time and space , A portable way of free transmission and sharing, suitable for schools, hospitals, business hotels, government departments, restaurants, public transportation, or any need to integrate multiple video content. 1080P high-definition video conferences improve call quality, high retrieval efficiency, fast delivery speed, and enable the extension of information exchange through video conferences, providing a great value for business, distance education, telemedicine, community, government and various charities Communication tools. People are demanding more and more display terminals for video conferences that can achieve large-size screens, high-definition, and multi-point simultaneous access, prominent visual display effects, flexible and diverse multi-point simultaneous access, and multi-point simultaneous display. It can ensure real-time audio and video collection, smooth running, high-resolution, high-definition picture display, etc. have become the environmental standards of video conference systems.

    Video image capture equipment-Video capture cards have a huge impact on high definition. In order to obtain high-resolution images in high-definition conference rooms, it is necessary to configure a 16: 9 standard video capture device that supports the minimum high-definition video standard 720p. Therefore, video conferences that use cameras now gradually use high-definition video capture cards. HD video capture cards can display high-resolution content (such as weather pictures, design drawings, accounting charts, maps, or medical photos) in high definition, which can bring great convenience to special industries that rely on visual communication. With the development and progress of the society, people have higher requirements for the timeliness, accuracy and comprehensiveness of information exchange. High-quality communication requires the use of richer, more vivid and mobile video communication methods. Therefore, the development of high-definition video conferences will have a revolutionary impact on people's lives and work.

    Miffy's HDMI HD capture card has high performance and low investment. It supports HDMI HD capture interface, Y / Pb / Pr HD capture interface (RCA), S-Video SD capture interface (DIN-4), CVBS SD capture interface (BNC). ), Compatible with 1080p signals, and has nothing to do with the screen display content, whether it is displaying video, text, pictures, web pages, can be guaranteed to be clear, continuous, and stable, thereby maximizing the needs of users. And can automatically detect the dynamic switching of various resolutions, and occupy a low CPU rate. Image processing such as scaling and de-interlacing that consumes CPU time is completed in the FPGA, which greatly reduces the burden on the CPU, and at the same time a highly efficient DMA transfer method It further frees the CPU's capabilities, allowing the CPU to focus on user-specified tasks. It has super stability, can run continuously without interruption, compact size, conforms to Low-profile standard, supports 2U chassis, uses PCI-E X1 slot, ordinary PC can be used, and the price is low, which meets the needs of video conference system users.
