DP571 Dolby

E Encoder User’s Manual Hardware Installation

1.4 Common Applications

The DP571 is most commonly used in three applications:

• Content creation

• Live remote transmission

• Digital television network rebroadcast

1.5 Content Creation

Figure 1-1 shows a typical postproduction configuration using Dolby E. A single

VRef black burst signal locks all units. In this example, the mixing console is used to

create a six-channel mix, which is then fed to the DP563 for surround encoding and

the DP570 Multichannel Audio Tool for monitoring and metadata authoring.

Metadata selections made while monitoring are sent from the DP570, to the DP571

encoder which adds this audio metadata to the 5.1 audio to make the Dolby E data

stream which is recorded to the VTR. The DP572 Dolby E Decoder is used for

confidence monitoring.
