Dolby ED2 Stream Selection and Decoding
Dolby ED2 streams can be carried over two SDI or AES channel pairs. The screen
may appear as shown in Figure 2-18. Although both channel pairs will be indicated
as containing a Dolby stream,
you must select the first (leftmost) of the two
streams in order to zoom into it
. This is because the iAM-12G-SDI is not able to
detect the start pair automatically. So in the case shown in Figure 2-18, you would
select the stream indication on channel pair 7-8 for a Dolby Zoom.

Note: If the iAM-12G-SDI has been configured to decode Pair-1 and Pair-2 as Dolby
ED2, and if for some reason the configuration is changed so that Pair-1 now has no
audio carried and Pair-2 now has PCM data, then the decoder will still keep
decoding the 4 pairs of PCM data and will output the PCM data available on Pair-2.
