ITU-656 The ITU Radio communication Sector
(ITU-R) is a standards body
subcommittee of the International
Telecommunication Union relating to
radio communication. ITU-656 (a.k.a.
SDI), is a digitized video format used
for broadcast grade video.
Uncompressed digital component or
digital composite signals can be used.
The SDI signal is self-synchronizing,
uses 8 bit or 10 bit data words, and has
a maximum data rate of 270 Mbit/s,
with a minimum bandwidth of 135
MHz.
