12G-SDI encoder transmission technology

SDI interface is a digital component serial interface and a digital video interface standard. At present, SDI interface is widely used in the camera industry. From the era of standard definition to high-definition, and then to ultra-high-definition 4K, the resolution has increased by four times on the basis of high-definition. We know that the resolution of 4K has increased to four times, the frame rate has increased to two times, and the baseband bitstream has increased to eight times.
The 12G-SDI can integrate four lines that transmit 3G-SDI signals into one line and directly transmit 4K audio and video. In this way, fewer lines are needed, the system is simpler, and the image quality is more guaranteed. In addition, 12G is backward compatible with 3G/HD/SD, so it is not a problem to access the existing HD switcher and other systems. At present, radio and television programs have officially entered the era of ultra-high definition, which not only brings more superior viewing experience to the audience, but also has higher requirements for the performance of video equipment. Therefore, the 12G-SDI encoder transmission technology can meet the business requirements of broadcasting and television IP-based video signal transmission.
