Driven by the digital revolution, video transmission technology is advancing at an unprecedented pace. Among relevant technologies, the SDI interface (Serial Digital Interface) stands out in the field of high-definition video transmission for its outstanding performance and wide application scenarios. Featuring high transmission speed, low latency and strong anti-interference capability, the SDI interface is widely adopted in broadcasting, film production, post-production, corporate video and many other sectors.

SDI Interface

The SDI interface adopts serial transmission. It breaks digital signals into multiple bits and transmits them efficiently through a single channel. This transmission method not only greatly increases signal transmission rate but also significantly reduces transmission latency, ensuring real-time performance and stability of video signals. In addition, the SDI interface boasts robust anti-interference performance. Advanced technologies such as channel coding and equalization effectively resist external interference and guarantee high-quality video transmission.

With continuous advances in video technology, SDI interfaces have also been upgraded iteratively. From the original SD-SDI to today’s 12G-SDI, the transmission rate has risen from 270 Mbps to 11.88 Gbps, meeting diverse transmission requirements ranging from HD to UHD. In the future, with the popularization of 8K, 16K and other ultra-high-definition video technologies, the transmission rate of SDI interfaces will be further improved to deliver more stunning visual experiences for video production and transmission.

Characteristics of SDI Interface

• High resolution support: The SDI interface supports multiple video resolutions including HD and UHD. For example, HD-SDI can transmit 720p and 1080i HD video signals, while higher-standard SDI interfaces such as 3G-SDI, 6G-SDI and 12G-SDI can carry higher-resolution video signals including 1080p, 4K and even 8K.
• High-quality transmission: SDI interfaces transmit uncompressed digital video signals to maintain high video quality during transmission. Transmission via coaxial cables further reduces signal attenuation and distortion, ensuring the receiving end obtains high-fidelity images consistent with those at the transmitting end.
• Strong anti-interference capability: SDI transmission incorporates multiple anti-interference technologies such as channel coding and equalization to effectively suppress signal noise and improve transmission quality. Even in complex environments, SDI maintains clear and stable video signals.
• Signal fidelity: Thanks to uncompressed transmission, SDI ensures integrity and fidelity of video signals. The images viewed at the receiving end are completely identical to those at the transmitting end without loss or distortion.
