DP572 Dolby E Decoder

 

 

 

 

4.1.1Main In

A Dolby E encoded signal is applied to Main In, sent to an AES3 receiver, then passed to the DSP subsystem for decoding. A PCM signal can also be input to Main In and passed directly to Digital Outputs 1/2. The DP572 automatically detects whether the Main In signal is Dolby E or PCM.

4.1.2Video Reference

An analog composite video reference signal is required for Dolby E decoding. Versions

1.05and later support two frame rates: 29.97 Hz (NTSC) and 25 Hz (PAL). If the video reference signal is not present or invalid, the:

DP572 will stop decoding the Dolby E bitstream;

PCM outputs on the decoder will be muted;

VRef LED will be red (Vref not present) or yellow (Vref unequal to frame rate of Dolby E Main Input).

4.1.3PCM Input

A separate PCM signal can be applied to the PCM Input and transported in parallel with the Main In signal. A delay equal to the main channel latency is added to the PCM signal.

4.1.4Remote

Future versions of the DP572 will permit remote control through the front- (RS-232) or rear-panel (RS-485) remote ports.

4.1.5Auxiliary

The RS-485 auxiliary port will be implemented in future versions.

4.1.610BASE-T

This port will be implemented in future versions.

4.1.7Metadata

Dolby Digital metadata is extracted from the Dolby E bitstream and sent out the metadata port. This port can be connected to the DP569 Dolby Digital Multichannel Encoder (software must be version 1.21 or later).
