VI (SMPTE RP 186-95/08)
The Video Index (VI) Config controls enable you to specify VI signaling output actions.
VI is valid for both 625 and 525 output video formats. The lines used are:
•
625: Field 1 line 11, field 2 line 324.
•
525: Field 1 line 14, field 2 line 276.
VI signaling supports two output formats, which are the two versions of the SMPTE RP 186
specification.
•
Mode:
Output options.
•
Auto:
When Output Format is set to SMPTE, Auto generates an output VI signal
conforming to SMPTE RP 186-95 with scanning system information that matches
the output aspect of the ARC. If Output Format is set to AFD, Auto generates an
output VI signal conforming to SMPTE RP 186-08, with scanning system
information and AFD that matches the output aspect of the ARC.
•
Pass:
When either VI SMPTE or VI AFD is selected as the input signaling
source, any valid SMPTE RP 186-95/08 input signal is passed through to the
output unchanged irrespective of what output format is set. For both output
formats, the output signal may not represent the actual aspect of the output
image. If no VI signal is present at the input, then no VI signal will be output.
•
Force:
When Output Format is set to SMPTE, Force generates an output
SMPTE RP 186-95 signal with scanning system information that matches what is
selected in the Force Output Signaling Setup – SMPTE RP 186 list. 4:3 and 16:9
are available, but the actual code used is determined by the output video
standard: 625 or 525.
When Output Format is set to AFD, Force generates an output SMPTE RP
186-08 signal with scanning system information and AFD codes that match what
is selected in the Force Output Signaling Setup – AFD list. The list contains eight
AFD codes for scanning 4:3 system information, and eight AFD codes for
scanning 16:9 system information. The actual scanning system information used
is determined by the output video standard: 625 or 525.
•
Delete:
Disables embedding of any SMPTE RP 186-95/08 output signaling in the
output video.
•
Output Format:
Output format options.
•
SMPTE:
Generates output VI signaling conforming to SMPTE RP 186-95,
carrying just the scanning system information relating to the output aspect of the
ARC.
•
AFD:
Generates output VI signaling conforming to SMPTE RP 186-08. This
carries the scanning system information as well as AFD codes relating to the
output aspect of the ARC. (This specification was originally generated as
ARDSPEC1 by several Major UK broadcasters and later incorporated into
SMPTE RP 186 2008 version.)
•
VI Pass Data:
Allows passing of VI user bits data to the output video. Note that the
input signaling source selected has to match the selected output format.
