Table A–5: Video Error Detection and Diagnostics
Characteristic Performance Requirement Reference Information
Video Error Detection
Type Active picture and full field. Field rate resolution. Uses
CRC check-word system. System is known as EDH
(Error Detection and Handling) in industry literature.
Complies with SMPTE RP165.
Reporting Means Front-panel ALARM lamp, rear-panel TTL line, and
CRT readout.
Error Statistics Asynchronous errored seconds. Active picture and full
field statistics are separately compiled.
Diagnostics
Embedded Audio Identifies the presence of up to 16 channels of
AES/EBU digital audio.
Ancillary Data Identifies the presence of ancillary data (other than
audio and EDH) and indicates if a checksum error has
occurred.
Format Errors Warns that a serial signal format error has occurred
Detected Errors:
1.
SAV placed incorrectly
2. Line length error
3. Field length error
4. Reserved values used improperly
5. ANC data checksum error
6. ANC data parity error
7. ANC data placement error
Signal Lost Reports absence of serial video signal
