Genlocking the Multiviewer
Genlocking the Multiviewer
A multiviewer must be referenced for any of the following reasons:
• the multiviewer must be genlocked with other plant equipment
• if minimal processing delay is required for your monitoring purposes
Otherwise, referencing the multiviewer is optional.
Genlocking a Densité 3+ FR1 Frame
To genlock the multiviewer with other plant equipment, a reference signal is required. For
this, certain requirements must be met.
• The Densité CPU-ETH2 Enhanced Ethernet Controller Card used in the Densité 3+ FR1
frame housing the multiviewer must use firmware version 2.0.4 or higher. A controller
with an earlier version of the firmware cannot provide a time reference to a multiviewer
card.
• If the time reference signal is provided by a Densité REF-1801 HD/SD Frame Reference
Module, this module must be configured as follows:
• An input reference signal must be connected to the BNC marked REF on the
REF-1801’s rear panel.
• The LTC source must be locked to the same reference signal.
• The
reference source
must be set to
External
(either from the card’s REFERENCE
menu or, in iControl, from the
Input
tab on the control panel for this card).
• In the case of a non-standard time code (for example, a count down time code, or a
time code that includes user bits with date information), the
time code processing
mode must be set to
Pass through
(either from the card’s REFERENCE menu or, in
iControl, from the
Input
tab on the control panel for this card). The pass through
mode is available as of version 1.10 of the REF-1801 firmware.
• The
URS generation mode
must be set to
Normal
(either from the card’s REFERENCE
menu or, in iControl, from the
Mode
tab on the control panel for this card).
Genlocking a Densité 3+ FR4 Frame
To reference a KMX-3921 multiviewer system, use the frame’s internal reference:
• In the case of a Densité 3+ FR4 frame, this is done by connecting the Densité CPU-ETH3
frame controller to the external house reference in every Densité 3+ FR4 frame that
contains KMX-3921 rear panels. The Densité CPU-ETH3 frame controller will distribute
the reference to all cards in the frame internally through the URS on the frame
midplane. The following conditions must be met:
Notes
• If the REF-1801 is configured properly, the Status LED on the front of the
card will be green. Improper configuration results in periodical time code
glitches. Refer to the REF-1801 HD/SD Frame Reference Module Guide to
Installation and Operation. See
• Using an LTC count down time code as the reference for a count up timer
is not supported.
