The given values force the following behavior of the SAA7114 VBI data slicer part:
•
•
•
Closed captioning data are expected at line 21 of field 1 (60 Hz/525 line system)
All other lines are processed as active video
Sliced data are framed by ITU 656 like SAV/EAV sequence (DID[5:0] = 3Eh
of SAV/EAV = 1)
