Conference Paper

Dolby E-A Practical Way to Distribute Multichannel Audio

Authors: Spath, Tony; Lyman, Stephen

AES Conference: UK 14th Conference: Audio - The Second Century · Paper ASC-16 · June 1999

Abstract

Dolby E Coding was developed to expand the capacity of an existing two channel AES/EBU digital audio infrastructure to make it capable of carrying up to eight channels of audio plus the metadata required by the Dolby Digital coders used in DTV transmission systems. This allows the existing digital video tape recorders, routing switchers and other TV plant equipment, as well as satellite and telco facilities used in programme Contribution and Distribution systems to handle multichannel audio. The coding system has been designed to provide broadcast quality even when decoded and re-encoded many times and to provide clean transitions when switching between programmes.
