DID:
This control allows the user to set the DID of the ANC packet to be passed through. Valid range
is 0x01 to 0xFF.
SDID:
This control allows the user to set the SDID of the ANC packet to be passed through. Valid
range is 0x01 to 0xFF.
Packet Location:
This control allows the user to specify whether the output ANC packet should be
located in the HANC or VANC region. By selecting
VANC,
the incoming packets will be inserted on
the VANC region of the output video. By selecting
HANC,
the incoming ANC packets will be inserted
on the HANC region of the output video.
Field 1 Output Line:
This control allows the user to set the field 1 output line of the ANC packet to be
passed through. The valid range is video standard dependent.
Field 2 Output Line:
This control allows the user to set the field 2 output line of the ANC packet to be
passed through. This control is only valid for interlaced output video standards. The valid range is
video standard dependent.
Interlaced to Progressive Conversion Mode:
This control allows the user to determine the method of
outputting the ANC packets on an interlaced to progressive conversion. By selecting
Pass Through,
the module will take an ANC packet from input field 1 and insert it onto output progressive frame 1 and
an ANC packet from input field 2 and insert it onto output progressive frame 2. By selecting
Duplicate
Packet,
the module will embed data from input field 1 onto both frame 1 & 2 on the output.
Progressive to Interlaced Conversion Mode:
This control allows the user to determine the method of
outputting the ANC packets on a progressive to interlaced conversion. By selecting
Pass Through,
the
module will take an ANC packet from input progressive frame 1 and insert it onto output field 1, and an
ANC packet from input progressive frame 2 and insert it onto output field 2. By selecting
Duplicate
Packet,
the module will embed data from input progressive frame 1 onto both output field 1 & 2. By
selecting
Field 1 Only,
the module will only embed the incoming ANC packets onto output field 1. By
selecting
Field 2 Only,
the module will only embed the incoming ANC packets onto output field 2.
Mapped ANC Packet Pass Through Status:
This field reports the current state of the ANC Packet
PassThru rule. The possible reported status values are:
Disabled
The ANC PassThru rule is currently
Disabled
Not
Detected
The ANC packet with corresponding DID and SDID (
if relevant
) is
not detected
on the
input video
Processing
The ANC packet with corresponding DID and SDID (
if relevant
) is present on the input
and actively being
processed
according to the defined ANC PassThru rule
Blocked
The ANC packet with corresponding DID and SDID (
if relevant
) is present on the input
and is being
blocked
from ANC PassThru processing because that same DID and
SDID is being processed by another component of the module (
For example: Source
ID
)
