emb_aud_hand_B
Embedded audio handling for channel B. This card has a built-in embedder, de-
embedder and audio gain stage. This menu item controls the functionality of
these stages.
•
Blank: blanks the horizontal blanking.
•
Pass: passes the audio un-processed.
•
Process: controls the ‘smart’ audio handling.
‘smart’ audio handling: the selected groups in the following Grp-A-Sel and Grp-
B-Sel setting item are de-embedded. The audio is routed through an audio gain
stage and is re-embedded in the selected group afterwards. This is performed
after the frame synchronizer. When a video (+embedded audio) frame needs to
be rewritten or removed as a result of an asynchronous SD/HD/3Gb/s input, the
audio gain stage ramps down the selected group prior to the action and ramps
up afterwards. This whole process masks audio irregularities that are audible in
a normal Frame synchronizer. When using the Pass setting DOLBY-E is
transfered with minimum delay.
Audio_Ctrl
With this setting you select how the audio presets should be controlled. Can be
either Manually (Manual), via GPI-triggers (GPI, GPI-A, GPI-B or GPI-C), via the
SD aspect ratio (SD-AR) or via the HD aspect ratio (S2016).
Audio_Prst_Act
With this item you can manually change the currently active audio preset. Can
be any preset between 1 and 16. By default it is set to 1. All menu settings that
are preceded by the #Emb prefix are part of the preset.
Audio_Prst_Edit
Here you can select which of the 16 selectable audio presets you want to edit.

#Emb prefix are part of the preset.
