3G-SDI is a successor to the HD-SDI interface. It uses the same style connectors and coaxial cables and is also downwards compatible. It provides an increase in bandwidth, which allows both higher resolutions and frame rates through a single connection.
HD-SDI is a global standard, specified in SMPTE292M and allows HD video data rate at 1.485 Gbit/s
3G-SDI (SMPTE424M) effectively doubles the bandwidth to 2.97 Gbit/s. Video data that previously needed two SDI connections can now use "only one cable" and images which couldn't be handled in realtime at all can now use dual-link 3G-SDI.
