3.13.8.5 Functional Description
Figure 3.109 Video Fail Mode Field
Video Fail Modes allow the broadcaster to define a failure screen upon loss of video
output. This loss can be due to either signal or video errors but as such the fail
screen does not always imply a video problem and therefore alarm messages
should be examined for the cause of the video failure.
The unit provides the following fail screens:
• Freeze Frame – This provides the last decoded frame of video as a still image.
If a frame is not available because the unit has been power cycled or the
decoder has been turned off, a black frame will be displayed instead.
Note: If the PMT Update Mode has been set to Flush or Refresh, this can result in
the video PID being dropped if not specified after a PMT update. If the video
PID is dropped, a Black Frame is displayed instead of a Freeze Frame.
• Black – This outputs a full screen Black Frame (0-7.5 IRE depending upon
standard) upon video failure.
• Blue – This provides a standard color blue (seen as blue on a vector scope) for
a full frame.
• 75% Bars and Red – This provides a set of calibrated color bars, these are not
SMPTE Color Bars but instead the top two-thirds of the picture contain seven
vertical bars at 75% intensity and the bottom third is filled with red.
Note: If the video is 1080P50/60, selecting this option will result in 100% Bars
being generated.
• Blue + Text – This is the same as the full field blue but also contains diagnostic
information about the failure that has occurred (not user configurable) as listed
below. Not supported for 1080P50/60 output.
- Cause of failure – This can be either video alarm detected (video decode
fail) or signal loss detected (error with the input signal).
- The service ID of the currently selected service.
- The serial number of the affected unit.
