Dual-Link HD-SDI is mainly two standard HD-SDI signals carrying a single image stream split between the two cables. The main
advantage is that color subsampling is no longer required, and the image can be transmitted in 4:4:4 quality, which then also allows
the RGB (or XYZ) color space to be used.
The main link will contain a standard HD-SDI signal, the second (enhancement) link contains the missing Cb and Cr samples.
Depending on the implementation the enhancement link could also contain extra information to increase the bit depth.
3G HD-SDI signal

3Gb/s
1080p 50/60 (Level A)
or
1080p 4:4:4 (Level B)
3G HD-SDI uses a higher data rate (2.97 Gb/s). This allows a single cable interface to achieve the same capabilities of a Dual-Link
HD-SDI implementation.
In direct mapping (level A) this is used to achieve higher frame rates. (50, 59.940 and 60 fps streams are supported).

and
HD 4:2:2 Signal #2
Dual Stream 3G is a speci
fi
c variant of the 3G signal which combines two completely separate 4:2:2 image streams into a single 3G
signal. This can be used to transmit stereoscopic streams by keeping the left and right eye signals together.
