Where is Dolby E used?

3. Dolby E is used in broadcast and post-production facilities to distribute multi-channel audio, six or eight channels, through a two-channel transport system. This occurs where there are equipment limitations, such as the number of tracks on a VTR for example, or where bandwidth requirements make multi-channel audio costs prohibitive such as with satellite capacity. Dolby E gets multi-channel audio to TV affiliate stations, so that they can transmit a multi-channel signal to consumers using Dolby Digital. Note that Dolby E audio never reaches the viewer at home. Like all DTV audio, it is decoded to PCM audio and then re-encoded into Dolby Digital just prior to transmission.
