ILLEGAL Code
An error is counted when the input signal data falls within the timing reference signal (TRS)
range or 000h to 003h and 3FCh to 3FFh are detected in the data other than those
specified by the ancillary data flag (ADF).
In SDI signals, 10-bit levels 000h through 003h and 3FCh through 3FFh are reserved for
the timing reference signal and the ancillary data flag, so they cannot be used for video
signal data or ancillary data. When data other than TRS and ADF data is found in these bits,
an error is counted.
•
Line Number (Other than SD)
An error is counted when the line number that is embedded in the input signal does not
match the line number that has been counted by the LV 5490.
•
Check Sum
The LV 5490 uses the checksum in the input signal's ancillary data header to count errors.
•
Parity
The LV 5490 uses the parity bit in the input signal's ancillary data header to count errors.
•
BCH (Other than SD)
Errors in the BCH code in the input signal's embedded audio are displayed here.
•
Parity (Other than SD)
Parity errors in the input signal's embedded audio are displayed here.
•
DBN
Continuity errors in the input signal's embedded audio are displayed here.
Embedded audio packets contain data block number (DBN) words that indicate the
packet's continuity. Packets are cyclically numbered from 1 to 255. An error is counted
when a packet's DBN is out of sequence.
•
Inhibit
An error is counted when embedded audio packets are found in lines where they should
not be embedded.
The embedding inhibit lines are as follows.
However, for 3G-B-DL 60p, 59.94p, 50p, 48p, and 47.95p, the transmission scanning mode
is interlace.
