Y Anc Checksum Error
: Displays the status of the Y channel ancillary
embedded checksum value that was calculated for the video signal. Using a
known test signal, the checksum status can be used to verify integrity through
a system. An error means that the Y Channel embedded checksum value does
not match the calculated checksum value, which indicates that a transmission
error has occurred.
•
C Anc Checksum Error
: Displays the status of the C channel ancillary
embedded checksum value that was calculated for the video signal. Using a
known test signal, the checksum status can be used to verify integrity through
a system. An error means that the C Channel embedded checksum value does
not match the calculated checksum value, which indicates that a transmission
error has occurred.
The CRC Status display is also divided into four columns:
•

o

o
Invalid

one error.
•
Err Secs
: The number of seconds, since the last reset, that contained at least
one error.
