Error checking parameters
CRC(EDH)
OmniTek XR 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 count shown reports the number of frames that have been in error since the value was last reset.
RGB Range Check
Indicates whether the YUV data would be valid if converted into RGB space. The count shown reports the number of frames since the count was last reset, in which the RGB values fell outside the values set on the Video: Analyzer page of the Engineering Settings control window. Both the minimum and maximum thresholds of the RGB valid range are programmable.
YCbCr Range Check
Indicates the validity of the YUV data. The count shown reports the number of frames since the count was last reset, in which the YCbCr values fell outside the values set on
