Include unscaled EAV:
0 = AVID period does not include the EAV sync codes (default).
1 = AVID period includes the EAV sync codes.
Include unscaled SAV:
0 = AVID period does not include the SAV sync codes.
1 = AVID period includes the SAV sync codes (default).
Include unscaled ancillary data:
0 = AVID period includes the ancillary data region (default).
1 = AVID period does not include the ancillary data region.
Include scaled EAV:
0 = AVID period does not include the EAV sync codes (default).
1 = AVID period includes the EAV sync codes.
Include scaled SAV:
0 = AVID period does not include the SAV sync codes.
1 = AVID period includes the SAV sync codes (default).
Include scaled ancillary data:
0 = AVID period includes the ancillary data region (default).
1 = AVID period does not include the ancillary data region.
Scaler PD (scaler power down):
0 = Scaler active
1 = Scaler powered down (default)
