Table 5-2. CRC Alarm Error Types (continued)
Error Type Description
RESERVED VALUES
USED IMPROPERLY
The Reserved Values Used Improperly alarm occurs when the eight most
significant bits (SD) or all ten bits (HD) are all “1” or “0” in any place other than
an EAV, SAV, or ancillary header.
ANCILLARY DATA
CHECKSUM ERROR
The Ancillary Data Checksum Error occurs when the internal calculated CRC
value is different from the received CRC value.
ANCILLARY DATA
PARITY ERROR
The Ancillary Data Parity Error occurs when the internal calculated CRC value
is different from the received CRC value.
ANCILLARY DATA
PLACEMENT ERROR
The Ancillary Data Placement Error occurs if an ancillary header appears
outside of blanking.
ABSENCE OF
SERIAL VIDEO INPUT
The Absence of Serial Video Input error occurs when the signal in the serial
video input is lost.
Loss of Carrier
The Loss of Carrier alarm occurs when there is no TRS (Timing Reference Signal)
detected.
Loss of Video
The Loss of Video occurs when active video falls below the adjustable threshold for a
period in excess of the duration setting.
Loss of Reference
The Loss of Reference alarm occurs when no sync signal is detected in the external
reference for a period in excess of the duration setting. To select the appropriate
external reference see Reference Selection on page 3-48.
Letterbox – SD
Letterbox is the top and bottom border surrounding the active video. The top border is
defined as having video below the threshold on the set line and having video above on
the following line. The bottom border is defined as having video above the threshold
on the previous line and video below the threshold on the set line. The Letterbox SD
alarm is activated when either the top line or the bottom line deviates from the user
settings (Standard definition only).
Pillarbox - HD
The PillarBox is the border to the right and left of the active video. The “End of Left
Border” and “Start of Right Border” defines the set points when the video is below the
threshold. If the video is outside of the threshold and CES values for the specified
duration, the Pillar Box HD alarm occurs (High definition only).
