Configuring the Streams for use with 4K UHD Two-Sample Interleave
Division
To support 4K streams, the image is mapped onto four HD sub-images using a Two-Sample
Interleave division (2SI), as defined by SMPTE ST 424-5. This means each of the four sub-
stream carries a quarter-resolution picture. These four sub-streams must be logically linked
together so that they are switched together at once ensuring that there is no switching
delay between the four streams that would create visible glitches.
Two-Sample Interleave division sub-images can also be carried over a quad stream, 1 x 12G-
SDI interface, as defined by SMPTE ST 2082-20.
The following shows the typical video stream composition of a two-sample interleave
division display.
To configure a 4K UHD Two-Sample Interleave Division input or output
1 Open the Link Control page. See Link Control on page 110.
2 Set Enable for the four spigots on which a quad link signal will be used (Spigots 1 to 4,
Spigots 5 to 8, Spigots 9 to 12, and Spigots 13 to 16).
3 Deselect the SDQS check boxes to use two-sample Interleave (2SI).
Disable SDI Sync
Bit
Some older SDI receiving equipment may not support sync bit
insertion. When transmitting signals to these devices, sync bit
insertion can be disabled by setting the boxes as required.
UHD ST352
(2SI/SDQS)
Set the quad-link signal type when
UHD Links
is set to
Enable
.
2SI:
The linked output is handled as 2SI with the associated VPID and
link number being applied. See Configuring the Streams for use with
4K UHD Two-Sample Interleave Division on page 111.
SDQS:
The linked output is handled as SQDS. If the control is
associated with an:
• IP sender then it is applied to a Quad Stream TPG.
• IP receiver then it is applied to a Quad Link SDI output. See
Configuring the Streams for use with 4K UHD SQDS on page 112.
Note:
ST352 control not valid for ST2022-6, and as such this setting is
ignored for this stream type.
