Serial Digital Interface (SDI) is an SMPTE standard for digital video transmission over coaxial cable. The SDI signal can also contain up to four independent digital audio signals along with the video signal. Two variations of SDI standard exist, based on the data rate: standard-definition (SD)-SDI and high-definition (HD)-SDI. The SDI standard is widely used in broadcasting and the video production industry because of the ability to transmit video signals over long distances with no loss of information.
The professional digital video connection format using a 270 Mbps transfer rate. A 10-bit, scrambled, polarity-independent interface, with common scrambling for both component ITU-R 601 and composite digital video and four groups each of four channels of embedded digital audio. SDI uses standard 75-ohm BNC connectors and coax cable.
The standard based on a 270 Mbps transfer rate. This is a 10-bit, scrambled, polarity independent interface, with common scrambling for both component ITU-R 601 and composite digital video and four channels of (embedded) digital audio. Most new broadcast digital equipment includes SDI which greatly simplifies its installation and signal distribution. It uses the standard 75 ohm BNC connector and coax cable as is commonly used for analog video, and can transmit the signal over 600 feet (200 meters) depending on cable type.
