ETSI TS 103 223

ETSI TS 103 223 specifies the object model, reference renderer, bitstream syntax and broadcast extensions forMDA. MDA, short for Multi-Dimension Audio, is a metadata model and bitstream representation of an object-basedsoundfield for linear content, for use in cinema and broadcast applications.

The present document consists of four main clauses. The metadata clause (Clause 4) provides a metadata modelindependent of (bitstream) representation, with a strong emphasis on cinematic content. Clause 5 specifies a referencerenderer, providing semantics for the MDA metadata model. Clause 6 specifies a preferred bitstream representation ofthe MDA metadata model. Note that the metadata model allows for more than one bitstream representation. Finally,Clause 7 specifies an extension of the core MDA model to include metadata and bitstream elements specifically suitedfor broadcast content. This Clause includes among others metadata for Loudness, Higher Order Ambisonics andInteractivity.

Unless otherwise stated, MDA metadata are specified using Unified Modeling Language [4].

Note that the MDA core metadata, reference renderer and bitstream documents have been submitted to SMPTE 25CSS”Immersive Sound Model and Bitstream” [i.2] for consideration towards an interoperable immersive sound model andbitstream for cinematographic linear content.
