LIVE DELAY ADJUSTMENTS
Delay adjustments can be made live. The apps apply the adjustments slowly over time, with
small delay adjustments therefore going virtually unnoticed. Increasing the delay slows down
the video until the delay is correct, while reducing the delay speeds up the video until the
delay is correct
VIDEO LOSS CONTROLS
The video loss/format mismatch controls allow the user to select what will happen to an
output in the event that the input is lost or the video format does not match the specified
format. The user can specify to freeze the last good frame or show a black or blue screen or
100% colour bars (with or without an initial delay of three seconds). No output can also be
selected. This is independently adjustable on each output
TEST PATTERNS
The test pattern controls allow the user to override an input and force the output to output a
test pattern including Colour Bars, Blue, Black, EqCheck, PllCheck, Pluge, Checkfield, Grey
Horizontal Steps, Grey Vertical Steps, Luma Horizontal Ramp, Luma Vertical Ramp, Cycle
Colour, Checker Board or Colour Square, or to freeze the picture. This is independently
adjustable on each output
AUDIO MUTE CONTROL
The output audio mute control allows the user to mute the audio embedded within any of the
SDI or ST 2022 outputs
SYNCHRONISER AND TIMING ADJUSTMENTS
Video sources are synchronised to common reference timing source
Choice of timing options:
•
PTP (SMPTE ST 2059-2) master and backup, via 10GbE IP network interface
•
Two tri-level syncs or analogue Black and Burst references (Reference 1 and Reference
2), connected via the Vision 3 frame
•
SDI video input, where available (defaults to SDI 1)
Chosen reference is the global reference source for all inputs and outputs
There are up to ten options for the reference selection, selectable via VisionWeb. The
hierarchy runs from left to right – should the timing source at the top of the list become
missing or invalid, the app will move down the list until it finds a valid timing reference source.
When used with IP inputs, the SDI reference option is not applicable and therefore the
reference will move to the next valid timing source:
•
PTP>Ref1>Ref2>Hold
•
