Background introduction of the plan:
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 conferencing has become a portable way for multimedia information such as text, documents, images, programs, etc. to be freely transmitted, spread, and shared without being limited by time, space, and geography. It is suitable for schools, hospitals, business hotels, government departments, restaurants, public transportation vehicles, or any need to integrate multiple video contents. 1080P high-definition video conferencing improves call quality, high retrieval efficiency, fast transmission speed, and opens up the information extension for communication through video conferencing. It provides a valuable communication tool for business, distance education, remote healthcare, communities, governments, and various charitable causes. People have increasingly high requirements for display terminals that can achieve display effects such as large-sized images, high definition, and multi-point simultaneous access in video conferencing. Outstanding visual display effects, flexible and diverse multi-point simultaneous access, and multi-point synchronous display methods can ensure real-time audio and video collection, smooth operation, and high-resolution and high-definition image display have become environmental standards for video conferencing systems.
Video image capture devices - Video capture cards have a huge impact on high definition. In order to obtain high-resolution images, high-definition conference rooms need to be equipped with video capture devices that support the minimum high-definition video standard of 720p according to the 16:9 standard. Therefore, video conferences that use cameras are gradually switching to high-definition video capture cards. High definition video capture cards can display high-resolution content in high definition, such as meteorological images, design drawings, accounting charts, maps, or medical photos, which can bring great convenience to special industries that rely on visual communication. With the development and progress of society, people constantly demand higher timeliness, accuracy, and comprehensiveness in information exchange. High quality communication requires the use of more diverse, vivid, and mobile video communication methods. Therefore, the development of high-definition video conferencing will have a revolutionary impact on people's lives and work.
Scheme system architecture diagram:
Meifeite Solution:
The Meifeite HDMI high-definition acquisition card has the characteristics of high performance and low investment, supporting HDMI high-definition acquisition interface, Y/Pb/Pr high-definition acquisition interface (RCA), S-Video standard definition acquisition interface (DIN-4), CVBS standard definition acquisition interface (BNC), compatible with 1080p signal, and independent of the displayed content of the picture. Whether it is displaying video, text, images, or web pages, it can ensure clarity, continuity, and stability, thus maximizing the satisfaction of user needs. And it can automatically detect dynamic switching of various resolutions, with low CPU usage. Image processing such as scaling and de interlacing that consume CPU time are completed within FPGA, greatly reducing the burden on the CPU. At the same time, the high-efficiency DMA transfer method further liberates the CPU's ability, allowing the CPU to focus on user specified tasks. It has super stability, can run continuously without interruption, is compact in size, meets the Low profile standard, supports 2U chassis, uses PCI-E X1 slot, can be used on ordinary PCs, and is inexpensive, meeting the needs of video conferencing system users.
