give a warning as with video black or video frozen. If a LED turns red this is a fault condition
so input present will turn red if the input should go away. A greyed LED will indicate an
absence such as non-alarm or non-warning status.
Text is used where more information is required than can be inferred by a simple LED such as
video standards.
Status monitoring
Input Video and audio status
Input present and external reference is indicated by a simulated LED; green will indicate that
the input is present, red for no input. The video standard of the incoming video and external
reference is also given in text.
Audio present on the input video and output video is indicated by green LEDs, one for each of
the four available audio groups. Should an audio group be missing the corresponding LED
will be greyed out. Silence on any pair of channels is indicated as well as the total delay
between the input and output video.
Synchroniser Control
The synchroniser control tab contains the various controls associated with the board mode and
video timing.
Lose of input and forced out are amongst the available controls. The forced out function is
particularly useful when setting up a system prior to programme availability.
