This interface describes a DASH formatted content that should go through the Dynamic Ad Processing box before going to the proxy through the IF-4C. But If my understanding is correct there is no mention of the possibility that the Ad Content can be available only on a mezzanine format or generally not at the right format/codec and should therefore be transcoded/processed in the next box.
This may be due to the fact that the document describes in length the interface but not much the function being executed in the boxes.
