3G HD-SDI signal
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
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.
