Comment on high-definition video conference camera
Videoconferencing has been transformed from the purchase of the most original SD equipment into high-definition video conferencing system integration. For front-end audio and video capture, medium-term video/audio compression, transmission, and later video/audio editing and recording must be focused on HD. Any non-HD device is used in a single loop. Even if the image and sound can be displayed without error, the quality of the original HD video conferencing camera will become standard definition quality.
Similarly, HD video cameras can only be the only solution for front-end high-definition video conference camera video capture. The standard imaging device for standard definition cameras is 1/4 CCD or CMOS. Pixels are between 400,000 and 500,000. For high-definition cameras, the imaging device is typically 3*1/3 CCD or CMOS with between 100 and 2 million pixels. Taking into account the wiring factors, high-definition cameras and high-definition video conferencing terminals are often connected through the SDI interface. The line that generally takes 50 meters is no problem.
Similarly, high-definition videoconferencing conferences can not only receive video images of ordinary high-definition videoconferencing cameras, but also be compatible with other broadcast-level professional HD cameras and images from high-definition switchers. So, how to route, route distance, and what kind of material to use for wiring is something we must consider. And only SDI is our only solution because it allows coaxial cables to carry lossless signals at a distance of 100 meters. And using the BNC head to make the line is very simple, without professional cables and connectors, you can easily buy in any computer market and audio store.
At present, large-scale domestic and foreign broadcast equipment suppliers have related high-definition conference camera equipment. The standard high-definition interfaces of these equipments are based on the HD-SDI interface.
