One of Dolby E’s most important features is its ability to carry Dolby Digital metadata. The DP571 can receive metadata from an external device, such as a metadata authoring tool, or it can generate metadata internally. The DP572 decodes the Dolby E signal, extracts the metadata and sends it to the DP569 Dolby Digital encoder. Use a standard DB9 male-to-male cable (not a null modem) to connect the Metadata output on the DP572 decoder to the Aux Data input on the DP569.

Note: To be used effectively in a Dolby E system, the DP569 must have software version 1.21 or later.

Figure 1-2shows the audio connections between the DP572 and DP569. Connect the DP572’s Digital Output channels 1/2, 3/4, 5/6 to the DP569’s Digital Input channels 1/2, 3/4, 5/6, respectively. Install 75 Ω terminators if the loop-through BNC connectors on the DP569 are unused.

When a DP569 receives external metadata, the following parameters must be explicitly set:

•Set the Metadata Source to External.

•Set the Metadata Program to Program 1.

•Set the Metadata Reversion mode. Last Used is recommended for a DTV facility because it is the only setting that continues encoding if the external metadata source is interrupted. See Metadata Revert on page 3-9for a complete discussion.

Figure 1-2also shows signals applied to the PCM Input and Status connectors. The Status signals can command the DP572 to change modes to allow the PCM Input signal to be mixed with (Voiceover) or replace (Switched Out) the Dolby E decoded audio. This feature is particularly useful in a facility that must pass network-originated multi- channel audio but can route a maximum of four channels. Voiceover and Switched Out modes are effected within the DP572 and therefore require no additional processors.

Both modes are described in detail in Output Routing on page 4-8.
