1 Introduction

Dolby E is used to transmit audio-for-video from a network center to affiliate stations, where it is

decoded into analog or PCM, or re-encoded into Dolby Digital for rebroadcast to the consumer.

The Dolby E data takes the space of a stereo pair of digital audio, at 48 kHz. Dolby E contains up

to 8 channels which can be divided in different ways to create up to 22 unique channel configura-

tions, called Program configurations. Each Program configuration is made of one or more pro-

grams, or groups of channels. A program can be a single mono channel, a stereo channel, or

multichannel surround sound up to 5.1 channels. A Program configuration can be combinations of

Programs such a 5.1 plus stereo. See Appendix A for a complete list of Program configurations.

This plug-in is available as a file-based-only plug-in. The plug-in reads up to 8 tracks of audio

from the host application, and encodes them into a single Dolby E file. The user interface allows

for easy selection of all available encoding parameters, including AC3 metadata.
