SMPTE 424M is a standard published by SMPTE which expands upon SMPTE 259M, SMPTE 344M, and SMPTE 292M allowing for bit-rates of 2.970 Gbit/s and 2.970/1.001 Gbit/s over a single-link coaxial cable. These bit-rates are sufficient for 1080p video at 50 or 60 frames per second.^[1] The initial 424M standard was published in 2006, with a revision published in 2012 (SMPTE ST 424:2012).^[2] This standard is part of a family of standards that define a serial digital interface (SDI); it is commonly known as 3G-SDI.
