Gamut Errors (Video)
The
Gamut Range
section of the Status display is divided into
YCbCr
,
RGB
and
Composite
data. In the Status Overview, it is further divided into two parts, the first providing details about
the current frame and the second providing
Session
data (i.e. min, max etc. data recorded since
the display was last reset).
The
YCbCr Range
section 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 in
the Video Config 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
minimum and maximum thresholds are set on the
Video Config
page of the Config window.)
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 Config 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. (The minimum and maximum thresholds are set on the
Video Config
page of the
Config window.).
The
Composite Range
section similarly gives the number of pixels for which the composite
value determined from the YCbCr data would be invalid as a percentage of the current frame, the
total number of frames for which the error level recorded in the Video Config was exceeded
since the last reset and a count of these error frames per second (EFPS). It also shows the
maximum and minimum values experienced. (The minimum and maximum thresholds are set on
the
Video Config
page of the Config window.).
Physical Errors (Video)
The entries in this section show parameters in error and give error counts for a range of standard
features of the video data stream. For instance, the
ANC
entry counts invalid ANC checksums.
The
Frames in Error
entry records the number of frames where any of the listed physical errors
have occurred.
The
Line
entry counts TRS packets where the line number specified does not agree with the line
number calculated internally.
Note:
This entry is only applicable to HD and 3G video: Line
numbers are not included in TRS packets in SD.
To check
CRC/EDH values
, the OTR calculates a new CRC value (EDH in SD) from the
incoming data, and compares this value with the CRC (EDH) value embedded in the data.
If there is a difference, this is flagged as an error. The CRC/EDH values that have been
calculated for the active area and for each full field/frame are also displayed
.
