High-definition video conferences have been converted from high-definition video conference equipment to high-definition video conference system integration. For front-end video / audio capture, video / audio display, mid-term video / audio compression, transmission, post-video / audio editing, recording All must be developed around high definition. Any link uses non-high definition equipment. Even if the image and sound can be displayed without error, the original high definition quality will become standard definition quality.
Similarly, for front-end video capture, high-definition cameras can only be the only solution. The standard imaging device for standard-definition cameras is 1 / 4CCD or CMOS . The pixels are also between 400,000 and 500,000. For high-definition cameras, the imaging device is generally 3 * 1/3 CCD or CMOS, with pixels between 1 million and 2 million. Considering the wiring factors, HD cameras and HD video conference terminals are often connected through the HD-SDI interface. It can reach a maximum of about 100 meters.
Similarly, high-definition video conferences can not only receive video images from ordinary high-definition cameras, but also be able to be compatible with images from other broadcast-grade professional HD cameras and high-definition switchers. Therefore, how to route, the distance, and the materials used for wiring are issues we must consider. Only HD-SDI is our only solution, because it allows coaxial cables to transmit signals losslessly at a distance of 100 meters. And the use of BNC head makes wiring very simple, no professional cables and connectors, can be bought at any computer market and audio store.
At present, large domestic and foreign radio and television equipment providers have related HD camera equipment, and the standard HD interfaces of these devices are all based on HD-SDI .
