2024年11月27日 · Serial Digital Interface (SDI) is a family of digital video interfaces first standardized by SMPTE (Society of Motion Picture and Television Engineers) in 1989. It is a standard for transmitting uncompressed digital video and audio using coaxial or fiber-optic cables. The SDI interface can not directly transmit the compressed digital signal.
What is Serial Digital Interface? - TechTarget
Serial digital interface (SDI) is a standard for digital video and audio transmission over coaxial or fiber optic cabling. Speeds currently range from 270 megabits per second (Mbps) up to 12 gigabits per second (Gbps) for the latest standard released in 2015. The SDI standard uses data words that are 8 or 10 bits in length.
