In ON and OFFSET modes, if 1.0 Audio Input is set to Channel Map or Stereo Map, the 6.x
Audio Delay menus for that pair are hidden.
If the Dolby Framer cannot lock the audio signal to the video output, an alarm is
triggered. (This may happen with non-Dolby E signals, or with Dolby E signals having an
incompatible frame rate.)
The Dolby Framer is incompatible with audio Channel Map mode. It works only with
Stereo Map or single-source audio inputs capable of carrying Dolby E pairs. If the Dolby
Framer is enabled while the input source is set to Channel Map, Analog, HDMI, or Dolby
Decoder, an alarm will result, and the Dolby Framer status will be shown as “Conflict”.
Also note that Dolby Decoder is not a valid Framer source, since the Dolby is already
decoded into PCM audio by the time it reaches the audio processor.
Dolby Framer status is available on the front panel Dolby Framer status menu or the
Status page of the web UI.
9.1 Dolby Framer Input
This parameter is visible only if 9.0 Dolby Framer Sync is set to On or Offset; the
parameter is hidden when 9.0 is set to Off.
The Dolby Framer Input can sync incoming Dolby E bit streams to the local reference so
they can maintain A/V sync when recorded onto VTRs or servers or when passing
through downstream facilities. You can set which pair of channels contains the Dolby E
stream to output synchronized with the reference. The Dolby Framer Input feature only
works with Dolby E inputs.
9.2 Dolby Framer Offset
(Frames)
This parameter is visible only if 9.0 Dolby Framer Sync is set to Offset; the parameter is
hidden when 9.0 is set to Off or On. The parameter adjusts the audio delay in frames,
providing a coarse timing adjustment.
9.3 Dolby Framer Offset
(Samples)
This parameter is visible only if 9.0 Dolby Framer Sync is set to Offset; the parameter is
hidden when 9.0 is set to Off or On. The parameter adjusts the audio delay in samples,
providing a fine timing adjustment.
