Gamut Information
The Video page of the Status display shows errors associated with YCbCr and RGB data. (The range of
acceptable values is set on the Video page of the Configuration window.)
See the "Video Status Section" section in the Configuration chapter for details.
The YCbCr section of this display gives the number of pixels for which the YCbCr data is in error as a
percentage of the current frame, the total number of frames for which the error level recorded on the
Video page of the Configuration window was exceeded since the last reset and a count of these error
frames per second (EFPS). It also shows the maximum and minimum Y, Cb and Cr values experienced.
The RGB Range section gives the number of pixels for which the YCbCr data would be invalid if
converted to RGB space as a percentage of the current frame, the total number of frames for which
the error level recorded in the Video page of the Configuration window was exceeded since the last
reset and a count of these error frames per second (EFPS). It also shows the maximum and minimum
RGB values experienced.
Timecode Information
The system checks the input stream for timecode data. Where a timecode is present, it is displayed
alongside the corresponding timecode type.
VITC This displays the vertical interval timecode if present on the currently selected
SDI source.
LTC This displays the longitudinal timecode if present on the currently selected SDI
source.
ATC VITC1 This displays the vertical interval timecode extracted from the ancillary
timecode data packet for VITC1 if present on the currently selected SDI source.
ATC VITC2 This displays the vertical interval timecode extracted from the ancillary
timecode data packet for VITC2 if present on the currently selected SDI source.
ATC LTC Ancillary Timecode Longitudinal Timecode. This displays the longitudinal
timecode extracted from the ancillary timecode data packet for LTC if present on
the currently selected SDI source.
SMPTE 352 Packet Information
The system will check for the SMPTE 352 packet on each physical cable and each virtual link of the
currently selected video source and display the decoded packet for both the Luma and Chroma data
streams for field 1 and field 2. The displayed results can be compare against the format detected by
the system itself.
Error Ranges, Persistence and Severity
The level at which any aspect of the video becomes in error, the length of time that this condition has
to persist for an error to be reported and the severity of that error (Error/Warning/OK) is part of the
system configuration. The Ultra is delivered with these levels set in accordance with standard practice
within the industry. The current settings can be viewed and adjusted in the
Configuration
-
Video
menu.
See the "Video Status Section" section in the Configuration chapter for details.
The display also allows you to require that an SNMP Trap is generated when an error occurs.
The settings are of two types: thresholds above/below which the associated parameter is deemed to
be in error; and counts of the number of differences between the expected value and the actual value
of video fields such as TRS codes and CRCs, above which an error should be reported.
