PTP>SDI>Hold
(“PTP” means PTP Master>PTP Backup. “SDI” means SDI1>SDI2>SDI3>SDI4>SDI5>SDI6,
dependent on number of SDI available. “Hold” means it will hold the timing of the last good
reference)
When using video reference, video inputs can be different formats but only inputs with the
same frame rate as reference video will be locked to that reference. Input signals of same
frame rate as reference will be locked together and locked to external reference. Inputs with a
differing frame rate will be locked and maintain timing with no drift, but their sync point will be
undefined (all same frame rate signals will, however, be locked to each other)
When using PTP reference, input sources of different format and/or frame rate will all be
correctly locked to the PTP reference
PTP timing reference should be used when there is a ST 2110-20 output to ensure the RTP
timestamp is related to the time of day. However without a PTP reference, a valid ST 2110-20
signal will still be generated using a free running RTP timestamp
When Auto relock enable is selected, the card will automatically relock when a lost reference
is restored. Selecting Force lock (with Auto relock disabled) will force the synchroniser to
relock after a reference is restored, and can be activated at a non-critical time to avoid video
disturbance
Output timing can be fully adjusted with respect to the reference using three time-based
controls: 0 - 42ms adjustable in 0.1ms steps, 0 - 100us adjustable in 1us steps and 0 - 1us
adjustable in 5ns steps. Sub frame timing alignment to chosen reference is global to all
outputs
ANCILLARY DATA
All ancillary data (including audio and locked Dolby E) is passed from SDI or ST 2022 input to
SDI or ST 2022 output. When ST 2110 input or output is selected, all ancillary data is
discarded
LED INDICATION OF:
Power okay
PRESETS
The current app settings can be saved in one of 16 locations to be recalled as required
App settings and Input/Output configuration settings can be stored and recalled independently
SIGNAL MONITORING
Comprehensive SDI, IP and PTP monitoring information is available and can be used to
generate SNMP traps
Checks can be performed on the following video and audio parameters:
•
Video present and time present
•
Video format
•
Video black
•
Video frozen
•
Video error
•
Audio group 1 present
•
Audio group 2 present
•
Audio group 3 present
•
Audio group 4 present
