Serial Digital Interface (SDI) is a serial link standardized by ITU-R BT.656 and the Soc iety of Motion Picture and Tele-
vision Engineers (SMPT E). SDI transmits un comp ressed dig ital video over 75-o hm coaxial cable within studios, and
is seen on m ost professional video infras tructure equipment. The first revision of the standard, SMPTE 25 9M, was
defined to carry digital representation of analog video such as NTSC and PAL over a serial interface and is more pop-
ularly known as standard-definition (SD) S DI. The data rate required to transmit SD SDI is 270 Mbps. W ith the advent
of high-definition (HD) video 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 sam e 75-ohm coaxial cable. S tudios and other video production facilities have invested heavily on
the hardware infrastructure for coaxial cable and have a vested interest in ex tending the life of their infrastructure. For-
tunately, SMPTE recently ratified a n ew standard called S MPT E 424M that doubles the S DI data rates to 2.97 Gbps
using the same 75-ohm co axial c able. 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 four times the
bandwidth of standard HD-SDI will be soon available.
