Figure 2-5 Diagram of Voiceover and Switched Output Operation
Use the Voiceover and Switched Output functions when only basic control and
editing functions are required. One example may be a local transmission center where
the switched output could be used to insert a local commercial delivered as stereo
PCM audio. The DP572 can also be used to insert voice-overs. This is advantageous,
because recording the voice-over might otherwise require 5.1-channel editing facilities.
2.7.7 Auxiliary Data
The Auxiliary Data port is a 9-pin male RS-232 port that may be used for future
enhancements. See Section 5.2 for pin assignments.
2.7.8 Metadata Output
The metadata output port is an RS-485 port. This can be used for the output of
metadata to a DP569, DP571, or other unit with metadata input. See Section 5.2 for
pin assignments.
2.7.9 10BASE-T
This port will be implemented in future versions.
