•
Direct ANC PassThru overrides Mapped ANC PassThru when it is enabled and Input Video
Standard is identical to the Output Video Standard
•
When Direct ANC PassThru is disabled or invalid, Mapped ANC PassThru rules are applied.
•
Supports SD-VBI waveform pass through for SD video.
•
ANC packets processed by the system (For example: Source ID) will be blocked from passing
through to avoid duplicate entries on the output video.
The
Mapped ANC PassThru mode of operation routes up to 10 unique (DID, SDID) ANC packets
frame accurately from input to output. This mode of operation is designed for the use case when the
input video standard and output video standard differ, or when only a subset of the ANC data on the
input is desired to be passed through the module.
The Mapped ANC PassThru provides a parameter set to fully define how each ANC packet will be
routed from input to output. This includes Packet Location (HANC or VANC), output line numbers and
interlaced to progressive and progressive to interlaced ANC data mapping.
Key Functional Notes of Mapped ANC PassThru:
•
Supported for all valid input and output video standard combinations.
•
When enabled and valid, Direct ANC PassThru overrides Mapped ANC PassThru .
•
ANC packets processed by the system ( For example: Source ID ) will be blocked from passing
through using Mapped ANC PassThru to avoid duplicate entries on the output video.
The ANC PassThru tab contains all controls relating to ANC pass through processing. Figure 5-26
illustrates the layout of these controls in the VistaLINK® PRO configuration view. The specific
functionality of each control is provided below.

NOTE: If the module is current processing the selected DID, SDID then the Mapped ANC
Packet PassThru Status will report blocked .
