Abstract: This paper addresses issues of audio distribution for modern DTV systems focusing on digital broadcast systems. In particular a model is described for handling audio and video elementary streams in existing distribution networks. The model supports new system architectures that allow audio and video coding to take place at many points in the distribution chain. The model covers both physical and logical interface formats, synchronization with associated video signals, and carriage of metadata associated with the audio. The model demonstrates that many audio features of new digital delivery formats can be exploited by existing broadcast systems with minimal additional equipment investment. The model makes use of existing AES and SMPTE standards, however new standards and recommended practices to support the open model may be desired by the industry. Specific recommendations are discussed. In addition, examples of systems applying the model to DTV broadcast facilities are described, including examples of products that implement the audio coding function using the model.
