What Is the Difference Between 3G-SDI and HD-SDI?

It is known that SDI interfaces can be roughly divided into three types: SD-SDI (270Mbp, SMPTE259M), HD-SDI (1.485Gbps, SMPTE292M) and 3G-SDI (2.97Gbps, SMPTE424M). It is seen from these standards of division that the rate is an important index. For HD-SDI and 3G-SDI, as the commonly-used two types in the radio and television industry, maybe there are still many people unfamiliar…
