Steve Lyman · 1999
The transition from 2 channel to 5.1 audio poses many challenges to audio distribution from the content producer to the point of emission coding for consumer delivery. This paper describes the application of a newly developed audio coding technology, Dolby E, to allow a 2 channel digital audio infrastructure to carry multichannel audio. The Dolby E coder is specifically tailored for use in with professional video, and provides a number of important features such as editibility in the coded domain, and carriage of audio metadata appropriate for the Dolby Digital emission coder.
