(1) See software-defined infrastructure, Single Document Interface, Strategic Defense Initiative and Switched Digital International.

(2) (Serial Digital Interface) SDI is a unidirectional video interface. Standardized by SMPTE in the late 1980s, SDI has been the primary interface for transmitting uncompressed digital video signals. SDI will eventually be replaced by IP-based NDI, and the many cables used in broadcasting facilities will be replaced with an Ethernet topography. See NDI.

SDI uses a high grade of coaxial cable and a BNC connector with Teflon insulation. It also supports optical fibers with ST, SC and FC connectors. Following are the common formats transmitted over SDI. See ITU-R BT.601, BNC connector, fiber-optic connectors and serial interface.

Two sockets are input, and two are output. At 4:2:2 color sampling, SDI uses one line for in or out. However, HD-SDI at 4:4:4 requires two lines. See chroma subsampling. (Image courtesy of Blackmagic Design Pty. Ltd, www.blackmagicdesign.com)
