Example 1—Overriding an Individual Parameter Value
We’ll assume you are using an external metadata stream. The output of the DP570 is
feeding a DP571 or DP569. You want to add a compression profile because none was
originally included. To do so:
1. Select the program you wish to change.
2. Click the Dynamic Range metadata tab on the DolbyRemote 570.
3. Click the radio button to change the source of the Line Mode Compression from
external to internal.
You can now select one of the five compression profiles (for example, Film Light).
