Serial Digital Interface (SDI) is a serial link standardized by ITU-R BT.656 and the Society of Motion Picture and Tele-
vision Engineer s (SMPTE). SDI transmits uncompressed digita l video over 75-ohm coaxial cable within studios, and
is seen on most professional video infrastructure equipment. The first revision of the standard, SMPTE 259M, was
defined to carry digital representation of analog video such as NTSC and PA L over a serial interface and is more pop-
ularly known as standard-definition (S D) SDI. The data rate required to transmit SD SDI is 270 Mbps. With the advent
of high-definition (HD) v ideo standards such as 1080i and 720p, the interface was scaled to handle higher data rates
of 1.485 Gbps. The 1.485-Gbps serial interface is commonly called the HD SDI interface and is defined by SMPTE
292M, using the same 75-ohm coaxial c able. Studios and other video production facilities h ave invested heavily on
the hardware infrastructure for coaxial cable and have a vested interest in extending the life of their infrastructure. For-
tunately, SMPTE recently ratified a new standard called S MPT E 424M that doubles the SDI data rates to 2.97 Gbps
using the same 75-ohm co axial cable. This new standard, also called 3-Gbps (3G )-SDI, enables higher resolution of
picture quality required for 1080p and digital cinema. 6G-SDI, a new ev olution of this standard with f our times the
bandwidth of standard HD-SDI will be soon available.
