5.8 Video payload legalizer (no settings)
This module has the SDI legalizer permanently enabled. The legalizer hard clips the
upper and lower limit of the video payload to the following limits:
Upper limit Luma: 3ACh
Chroma: 3C0h
Lower limit Luma: 040h
Chroma: 040h
5.9 EDH processing block (no settings)
This module has the EDH processing block permanently enabled. The EDH processing
block extracts the EDH package from the video, updates the EDH flags according to
SMPTE RP165 and inserts the EDH package into the ancillary data of the video.
5.10 Video output selection
The board has four SDI outputs in total, but they form two pairs where each consists of
one inverted and one non-inverted BNC output (see Table 2: Connector functions on
page 10). The routing is controlled per pair.

When processed is selected, it is possible to either output video generator or mute the
output. This is done at the video in - mode by selecting Video gen. or Mute. This will
not have any effect on outputs set in through mode.
5.11 Audio de-embedder and embedder (no settings)
The Audio de-embedder extracts all audio embedded in the video stream. The de-
embedder is always enabled, and for this module the embedder is also permanently
enabled, otherwise it would not be possible to fade audio with the video.
