Abstract: As the demand for multichannel audio increases, handling 5.1 sound channels within today's two-channel audio infrastructure has become a significant issue. To address this need, a new coding system called Dolby E capable of carrying up to eight channels of audio through a traditional stereo infrastructure, has been developed. While this system is based on perceptual coding principles and audio data compression, it has also been designed to meet constraints imposed by operational practices of program production, such as video frame boundary editing and multigeneration use. This paper provides a technical overview of the system, describing the architecture and design of the encoder and decoder. It also details the work currently under way on standardizing how stereo broadcast equipment should handle and pass such signals, and the ways this technology is being made available to manufacturers of broadcast system components.

Steve Vernon has been with Dolby Laboratories since 1991. He currently serves as leader of the Consumer Division's Technology Group, which is responsible for identifying, acquiring, and developing licensable technologies for the consumer market. Prior to this he worked in Dolby's R&D department and was part of the development teams for several perceptual coding systems, including Dolby Digital and Dolby E. Vernon received a BSEE from the University of Southern California in 1986, and an MSEE from Stanford University in 1987. He is a member of the AES, and is a co-inventor on several Dolby patents.
