Dolby Model DP583 Frame Synchronizer User’s Manual Front-Panel Menus

4-4

4.3 Setup Menu

Options in the top menu level are:

• Operating Mode

• I/O Control

• System Settings

4.3.1 Operating Mode

The Operating Mode menus allow configuration of which audio formats are

processed and the total delay through the DP583.

The submenus are:

• Bitstream Detect

• Dolby E Delay

• Dolby Digital Delay

• PCM Delay

Bitstream Detect

The Bitsream Detect submenu controls which audio format (Dolby E, Dolby

Digital, or PCM) the DP583 will recognize and process. A chosen format will be

processed and be passed through to the main output of the unit. If an audio format

that has not been chosen is input to the DP583, the unit will recognize it and the

output will mute. Autodetect allows all three audio formats to be recognized,

processed, and output.

Dolby E Delay

The Dolby E Delay can be set to a value from 0 to 6 video frames. This delay is in

addition to the internal processing delay, which is between one and two frames.

Dolby D Delay

The Dolby Digital Delay can be set to a value from 0 to 256 msec, in steps of 32

msec. This delay is in addition to the internal processing delay, which is between 32

and 64 msec.

PCM Delay

The PCM Delay can be set to a value from 0 to 260 msec, in increments of 1

msec. The default is 43 msec. This delay is in addition to any delay due to the

internal processing and TTL tracking input delays. The internal processing delay

is 5 msec, and is required for clean switching.
