Driven by the digitalization trend, video transmission technology is evolving at an unprecedented pace. Among relevant technologies, the SDI interface (Serial Digital Interface) stands out in high-definition video transmission thanks to its outstanding performance and versatile application scenarios. Characterized by high transmission speed, low latency and strong anti-interference capability, SDI excels in broadcasting, film production, post-production, enterprise video and many other fields.

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, guaranteeing real-time performance and stability of video signals. Furthermore, the SDI interface boasts robust anti-interference performance. With advanced technologies such as channel coding and equalization, it effectively resists external interference and ensures high-quality delivery of video signals.

As video technology advances, SDI interfaces keep upgrading. 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, SDI transmission rates will be further increased to deliver a more immersive visual experience for video production and transmission.

Features of SDI Interface

• High Resolution Support: The SDI interface supports multiple video resolutions including HD and UHD. For instance, HD-SDI transmits 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 transmits uncompressed digital video signals to preserve superior image quality during transmission. Using coaxial cables further reduces signal attenuation and distortion, ensuring the receiving end obtains the same high-quality images as the sending end.
• Strong Anti-Interference: Multiple anti-interference technologies including channel coding and equalization are applied in SDI transmission, effectively mitigating signal interference and improving transmission quality. SDI can maintain clear and stable video signals even in complex environments.
• Signal Fidelity: Thanks to uncompressed transmission, SDI guarantees the integrity and fidelity of video signals. This means images displayed at the receiving end are identical to those at the transmitting end without any loss or distortion.
