Switching Between Hd And Uhd Configurations - Telestream Lightspeed Live Capture User Manual

•
Cisco ID3—Enable to allow the SCTE-104 information to be converted to ID3 on
output. This option can also be turned off or on from Live Capture when configur-
ing SDI sources. See Cisco ID3 in the Configuring SDI Source Options topic in the
Lightspeed Live Capture User Guide. This setting is available only in Advanced Mode.
•
VDCP—When enabled, activates the RS-422 port in VDCP (Video Disk Control Pro-
tocol) mode (RS-422 timecode is not available). This setting is available only in
Advanced Mode (System Settings).
•
Extended RS-422 Status—When enabled, the RS-422 port is polled for extended
error status information and the data is added to the log files. Available only in
Advanced Mode (System Settings).
•
Ignore 4K Format Match Check—When enabled, Live Stream adds a UHD/4K
source via SDI inputs even if all four quadrants do not have a matching signal.
When there is not a valid 4K signal from all quadrants, the entire output displays the
4K signal as the LOS Video Test Pattern. When disabled, all four quadrants of a UHD/
4K source must match for the 4K mode to be activated. Unmatched quadrants can
occur when some UHD/4K sources are not currently playing video.
•
4K Video Input—Sets the source to 4K video input. When activated, all four SDI
inputs are merged into one 4K input. Choose from one of the following Quad-Split
Schemes:
–
Square Division—The image is divided into four quadrants.
–
2SI-A—Two Sample Interleave, type A.
–
2SI-B—Two Sample Interleave, type B.
Note: To successfully switch between the 2SI-A or the 2SI-B setting, you must first
select Square Division, save the change, then reopen the dialog and select the A or B
setting you want to switch to.
Note: The SDI inputs on the Lightspeed server cannot differentiate between 4K and
HD/SD signals. When the server inputs are receiving a 4K signal, but the 4K Video Input
switch is not enabled, the four corners of the source are divided into the four SDI
inputs. To get one source that will use the full 4K signal you must enable the 4K Video
Input switch in one of the SDI inputs.
When the SDI inputs are receiving HD/SD signals and the 4K Video Input switch is
enabled, there will be a single SDI 4K input source that has four segments of duplicate
video in it. All four inputs must be synchronous, and have the same frame rate and
resolution in order to be combined into a single source view.

Switching Between HD and UHD Configurations

The key ingredient to enabling or disabling the UHD mode is that a valid and active
UHD signal must be connected to the Lightspeed Live server during the switching in/
out of UHD mode process. To successfully switch from an HD configuration to a UHD
input, and then back again, follow the procedures described below.
