Group examples
•
Select a group from within the SDI stream for de-embedding
Example:
A=Agroup=n or B=Agroup=n
If the display text starts with A or B, de-embedding is implied. Providing the ‘=’ sign
appears before the group number, audio will be de-embedded.
•
An attempt is made to de-embed from a non-existent group
Example
:
A=Agroup n or B=Agroup n
If the display test starts with A or B, de-embedding is implied. However, if the ‘=’
sign does NOT appear before the group number, then NO audio will be de-embedded
at this in time as no suitable input is currently present.
•
Select a new group to embed to
Example
:
C=Agroup n
If the display test starts with C, E, or F embedding is implied. Providing there is NO
‘=’ sign before the group number, then there is no conflicting audio group present
and audio will be embedded into that SDI stream.
•
Select an existing group to embed to
Example
:
C=Agroup=n
If the display test starts with C, E, or F embedding is implied. The ‘=’ sign before the
group number indicates that it already exists. There is a conflicting audio group
present.
New audio will be embedded into that SDI stream and the incoming Audio Group
will be disabled automatically by changing the incoming Audio Group ID to
‘Marked for Deletion’. If there is no other audio input or data input other than the
conflicting audio group input, HANC blanking will automatically be asserted.
Tip:
Always set embed or de-embed functions to unassigned when NOT in use (eg
A=Agroup-). The ‘-’ sign will disable auxiliary functions such as ‘Marked for Deletion’
and will help avoid invalid operations or unexpected results.
