In scenarios such as drone aerial photography, telemedicine, high-end video conferencing, and industrial inspection, 4K ultra-high-definition picture quality and 60 frames per second smoothness have become essential needs in the industry.
Xuanzhan Technology, a provider of high-definition video secondary development solutions, has independently developed a 12G-SDI interface board. With core advantages such as a single-cable 12Gbps high-speed transmission rate, lossless picture quality, and multi-protocol compatibility, it offers industry users a dual-core-driven solution.
I. What is 12G-SDI?
12G-SDI is a high-bandwidth serial digital interface standard that supports a data transmission rate of up to 12Gbps and can lossless transmit video signals at 60 frames per second at 4K resolution. Compared with the traditional 6G-SDI or 3G-SDI, the transmission rate of 12G-SDI has increased several times, completely solving the bandwidth bottleneck problem of 4K ultra-high-definition video transmission. Moreover, it features strong anti-interference ability and stable and reliable transmission, making it particularly suitable for long-distance transmission requirements.
To understand the differences among HD-SDI, 3G-SDI, 6G-SDI and 12G-SDI, the key lies in comprehending their continuously upgraded transmission capabilities and the corresponding application scenarios.
