Dolby E Alignment – Provides selectable Dolby E alignment for
embedded Dolby E to position the bitstream utilizing the Dolby E
“guard band”. This helps prevent frame errors that may occur in a
bitstream upon switching or editing.
• Dolby E Embedding Alignment Control
For incoming Dolby E data routed to the device audio bus, aligns the
embedded Dolby data corresponding to selection. Alignment line as a
result of selection is shown in Status display.
Note: • Where a frame reference is available, it is recommended to use
the Align to Reference selection. This helps ensure that the
correct alignment is achieved even if the video is user delayed or
output format (scaling) is changed.
Refer to “Preferred Alignment for Dolby E in HD Systems”
(http://www.dolby.com/about/news-events/
newsletters-dtvaudio-dolby-e-alignment.html) for more
information regarding Dolby E alignment.
• This control applies only to externally received Dolby E data
streams.

• Per-Channel Audio/Video Delay Offset Controls
Offset control adds or reduces (offsets) channel audio delay from the matching video delay (audio delay offset setting adds
or removes delay in addition to any delay included by other actions). This control is useful for correcting lip sync problems
when video and audio paths in the chain experience differing overall delays.
(-800.0 to +800.0 msec range in 0.02 msec steps; null = 0.0 msec)
Delay Status shows current delay from video for the corresponding audio channel.
Note: • Maximum advance/delay offset is dependent on video format.
• Where a Dolby pair is present, adjustment of either channel control results in a matching delay setting for the other
channel in the pair.
