Quality is the main direction for the development of
high-definition cameras
High-definition video conferencing has been transformed from the original SD videoconferencing equipment purchase to high-definition video system integration, for front-end video/audio capture, video/audio display, mid-stage video/audio compression, transmission, post-view video/audio editing, and recording. Must be to focus on high-definition, any one ring is used in non-high-definition devices, even if the image, sound can be displayed without error, but 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 1/4 CCD, or CMOS. The number of pixels is between 400,000 and 500,000. For high-definition cameras, the imaging device is generally 3*1/3 CCD or CMOS, and the pixels are between 100 and 2 million. Taking into account the wiring factors, HD video cameras and HD video conferencing terminals are often connected via the HD-SDI interface. It can reach up to 100 meters.
