PACK
-
generates a new audio frame structure (is deleting all former existing
embedded audio!)
-
is embedding selected TX group as first audio group within SDI stream
-
necessary if no audio was embedded before
CASCADE
-
generates a new audio group as selected (TX group) within existing
frame structure (is overwriting all data of this group if it was already
existing)
-
necessary if a new group should be embedded and if audio in other
groups was embedded previously
-
is matching ideally the structure which was generated by PACK mode
(It is recommended to use PACK mode for generating audio
structure and embedding the first group before using CASCADE to
embedd further audio groups!)
Please note: As long as PACK and CASCADE are not set the embedder is
inserting in the group which is determined by RX group selection. The
embedder is replacing the existing audio if it was embedded previously.
If group 1 is selected and no audio structure is existing at the input the
embedder is switching to PACK mode for group 1automatically!
If group 2,3 or 4 is selected and no audio structure is existing for this group
the embedder is not inserting audio data (use PACK or CASCADE!).
