or
1080p 4:4:4
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).
Dual Stream 3G HD-SDI signal
3Gb/s
HD 4:2:2 Signal #1
and
HD 4:2:2 Signal #2
Dual Stream 3G is a specific 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.
