Filtering UAS KLV Metadata Tags
You can filter MISB 0601 metadata tags on a per tag basis, by specifying all or any subset
of the MISB 0601 tags. If a tag is included, it is allowed to proceed to the metadata elemen-
tary stream (ES). Tags that are not included are filtered out of the metadata AU and not
transmitted in the metadata ES. Non-MISB 0601 metadata (such as MISB 0605 or custom
metadata adhering to SMPTE 336) is not affected by the MISB 0601 filtering.
When filtering MISB 0601 metadata tag 48 (security metadata), you can also filter the
security metadata tags defined in MISB 0102.
This is useful to eliminate unwanted KLV information in order to minimize the metadata
bandwidth required. You may choose to down-scale and frame-decimate the video and
decimate the metadata as well.
To filter UAS KLV metadata tags:
1.
From the Metadata List View, click the link for the metadata source to filter.
2.
On the Metadata Detail View, to filter MISB 0601 metadata tags, toggle the UAS
KLV Tag Filtering button to
On
and select the scope of filtering from the Included
UAS Tags drop-down list (as shown in the following example).
● To fine-tune the list on a per tag basis, as you browse through the list, click
X
next
to a tag number/label to exclude the tag, i.e., filter it out of the metadata. This cre-
ates a new option “Custom Set” on the Included UAS Tags drop-down list.
● To re-include a tag that has been excluded, click the down arrow at the bottom
right of the list box and select the tag from the drop-down list of excluded tags.
