5. Input and Communication
3G-SDI
Serial Digital Interface (SDI) is a serial link standardized by ITU-R BT.656 and the Society of Motion Picture and Tele-
vision Engineers (SMPTE). SDI transmits uncompressed digital video over 75-ohm coaxial cable within studios, and
is seen on most professional video infrastructure equipment. The
fi
rst revision of the standard, SMPTE 259M, was
de
fi
ned to carry digital representation of analog video such as NTSC and PAL over a serial interface and is more pop-
ularly known as standard-de
fi
nition (SD) SDI. The data rate required to transmit SD SDI is 270 Mbps. With the advent
of high-de
fi
nition (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 de
fi
ned by SMPTE
292M, using the same 75-ohm coaxial cable. Studios and other video production facilities have 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 rati
fi
ed a new standard called SMPTE 424M that doubles the SDI data rates to 2.97 Gbps
using the same 75-ohm coaxial cable. This new standard, also called 3-Gbps (3G)-SDI, enables higher resolution of
picture quality required for 1080p and digital cinema.
