5.2 Dolby Atmos Content Not Recognized

If the Dolby Atmos content is not recognized, a gray or red dot will be present in the Dolby Atmos

Content section. (Refer to Figure 29)

Use the tips below to try and solve the issue:

• Verify the selected content is Atmos content. (Refer to Section 3.2 on how to verify the

content).

• Verify the audio processor is Enabled. (Refer to Section 3).

5.3 KDMs for Dolby Atmos Content (CPL)

All KDMs created to unlock encrypted Dolby Atmos content must have the audio watermark disabled

from only channels 12 and above.

Below is an example of what a correct KDM would look like:

5.4 Dolby Atmos Channel Drop Out

If the system experiences Dolby Atmos drop out, when the system is only outputting the base bed

audio channels, (that being the first 10 physical channels, e.g. 5.1 or 7.1). The reason could be

network drop out or the network is not running fast enough.

Check which ethernet port your CP850 is on, e.g. 10.203.50.10

In the drmreport.txt, search for "IP Interfaces"
