This document describes a constrained Broadcast Production subset of the ADM (Audio Definition Model - ITU-R BS.2076).
The Audio Definition Model (ADM) is intentionally very generic to support a wide variety of different application areas. The “ADM broadcast production profile” constrains the ADM to simplify implementations and to prevent interoperability problems in the production of Next Generation Audio broadcast programmes. It aims to do so by not limiting the possibilities the ADM offers. Every constraint introduced by the profile is accompanied by a transcoding instruction, which explains how an ADM using the full feature set can be converted to an ADM which complies with this profile.
