Aspect ratio - AFD source

Select the source of the metadata that will be used by this Kaleido-Solo for aspect ratio control:

AFD:

Selects AFD (SMPTE 2016) as the source for HD and SD (525, 625) aspect ratio descriptor.

VLI:

Selects VLI as the source for the SD (525, 625) aspect ratio descriptor.

WSS:

Selects WSS as the source for the SD (625) aspect ratio descriptor.

The Active Format Descriptor (AFD) flag is used to identify the aspect ratio and protected areas of a video signal.

The AFD flag is implemented differently in HD and SD:

 In HD, the AFD flag (SMPTE 2016) is sent as an ancillary packet, normally found on line 11 in the vertical ancillary

space.

 In SD, the AFD flag is sent as a Video Line Index (VLI) signal (RP 186), as a Wide Screen Signaling (WSS) signal

(ITU-R BT.1119-2) for 625 only, or as an AFD packet (SMPTE 2016).

Note that it is not possible to specify different sources for SD and HD, e.g.: VLI for SD and AFD for HD.

Time Code - SD Select Mode

Select whether time code extraction from SD video inputs will be automatic or manual.

Auto:

The vertical interval of the incoming video is scanned and the first detected time code is extracted.

Manual:

Time code will only be extracted if it appears on a specified line in the vertical interval.

In Manual mode only, the SD Select Line menu item is enabled, allowing the line number for extraction to be

specified.

Time Code - HD Select Type

Select the source of the timecode to be displayed when the input video is HD.

VITC:

Use ATC VITC time code (time code updated every field).

LTC:

Use ATC LTC time code (time code updated every frame).
