Dolby Monitoring Screens
Dolby Zoom Screen
Dolby Zoom
is a very powerful analysis tool. Much as a camera lens can "zoom"
into a single subject of interest out of many, the
Dolby Zoom
feature lets you
quickly "zoom" into a single Dolby bitstream, out of multiple encoded Dolby
streams and other channels. Simply rotate the
Adjust
control until the
Dolby bitstream, as identified by the Dolby icon (shown here at right), is
highlighted and then press the
Adjust
control. You can immediately
listen to and meter the contained audio channels, as well as view the Dolby
metadata. Bitstreams are shown distinctively along with the normal metering
channels, as shown in Figure 2-6. The
Dolby Zoom Screen
is shown in Figure 2-7.
Note:
The
Dolby Zoom
feature functions only for Dolby audio carried over
traditional signals. It is not available for Dolby audio carried over MPEG.
Dolby decoding is an optional feature requiring the OPT-DOLBY module. It
allows decoding and monitoring of Dolby® D, DD+, & E streams. Refer to the
System Setup
section in Chapter 4 and to Figure 4-13 to install software licenses.

When the
Dolby Zoom
screen appears, the speakers will automatically begin
monitoring the Downmix audio. However, you may solo or mute the individual
channels for troubleshooting or other purposes. Use the left screen to select other
Dolby E channels to be monitored. Touch and slide the control on the
Dolby
Metadata
screen to scroll through multiple lines of metadata.
The
Dolby Zoom
screen also displays Dolby CRC (Cyclic Redundancy Check)
Errors, which are automatically totaled. It only appears if there is at least one error.
Touching the "X" on the Dolby Error Count display, resets the count. The maximum
count is 65,535 and it will roll over to 0 and restart counting if this is exceeded.
CRC Errors are an indication that the Dolby signal is being disrupted, either by
