Serial Digital Interface (SDI) is a digital video format, used for the transmission of uncompressed video signal (RGB video) without encryption (optionally including audio). Is also used for transmitting data packets. The specifications of this format are specified in Recommendation ITU-R BT-656 for the transmission of video signals in digital components. Data transmission using 270 Mbits/s. In this section you will find all kinds of electronics on the SDI format and its derivatives: HD-SDI, SD-SDI and 3G-SDI.
