What Are Dual Link And 3G - Sony SRW-9000 Operation Manual

What Are Dual Link and
3G?
When the optional HKSR-9001 and HKSR-9003
are installed in this unit, you can select output of
HD SDI signals.
When HKSR-9001 is installed
HD SDI signal format
4:2:2 (YCbCr) 23.98PsF
to 29.97PsF (59.94i)
4:2:2 50P/59.94P
When HKSR-9001 and HKSR-9003 are installed
HD SDI signal format
4:2:2 (YCbCr) 23.98PsF
to 29.97PsF (59.94i)
4:2:2 50P/59.94P
4:4:4 (RGB) 23.98PsF
to 29.97PsF (59.94i)
This section explains the types of signals that you
can output with HD SDI 1.5G Single Link, 1.5G
Dual Link, and 3G Single Link.
1.5G Single Link
Single Link enables output of HD SDI signals
over a single BNC cable.
The unit can handle 4:2:2 (Y/Cb/Cr)/1080/
23.98PsF to 29.97PsF (59.94i) HD signals. The
HD SDI OUT A and HD SDI OUT B connectors
output the same signals. The number of pixels is
1920 × 1080.
1.5G Dual Link
Dual Link enables output of HD SDI signals over
two BNC cables.
With Dual Link, you can do the following.
• Handle different color spaces
Dual Link allows you to expand color
difference signals to RGB. When the optional
HKSR-9003 is installed, the unit can handle
4:4:4 (RGB)/1080/ 23.98PsF to 29.97PsF
(59.94i) HD signals.

When you do this, all of the G component and
half of the B and R components are output via
the HD SDI OUT A connector. The other half is
output via the HD SDI OUT B connector.
HD SDI OUT A = G/0.5 ×B'/0.5 ×R'
HD SDI OUT B = None/0.5 ×B"/0.5 ×R"
• Increase the number of frames
Dual Link allows you to double the number of
frames to 4:2:2 60P.
HD SDI OUT A = Even lines/Odd lines
(alternating on each frame)
HD SDI OUT B = Odd lines/Even lines
(alternating on each frame)
Note
In the SMPTE-372M 4:2:2 60P standard, the active lines
of digital field 2 are different between Link A and Link
B (Link A: line 584 to 1123, Link B: line 583 to 1122).
3G Single Link
You can output signals that correspond to 1.5G
Dual Link over a single BNC cable.
