6.9 Dolby E
The
Dolby E
screen enables the configuration of Dolby E settings.
6.9.1 Dolby E Alignment
•
Dolby E Auto Align:
This option enables Dolby E automatic (i.e. Dolby
recommended) alignment. When enabled, the Dolby E header is automatically
aligned with the video frame boundary to ensure error-free video switching. The slider
displays the relevant line number used for alignment. Realigned Dolby audio can be
routed to any audio pair by means of the L/Non-PCM controls on the Audio Embedder
screens if the embedded pair in set to Non-PCM. Note that “pass-through” Dolby E,
where neither embedder in a group is enabled, will not be re-aligned.
•
User Dolby E Line:
This option enables manual selection of Dolby E line. The slider
displays the relevant line number used for alignment, which may be changed
manually by dragging the slider. Clicking the
P
button returns the line number to the
preset (automatic) value.
6.9.2 Line Standard
By default the
Current
video line standard is always selected. A different line standard may
be selected by clicking the relevant radio button. The associated line number for the chosen
line standard will be displayed by the above slider control.
Note:
If Dolby E guard-band is out of spec, then Dolby E is re-aligned to that specified by Dolby.
