Introduction
The Dolby® DP580 Professional Reference Decoder is the first reference Dolby TrueHD
decoder, and serves all Dolby audio codecs, including Dolby Digital, Dolby Digital Plus™,
HE AAC with metadata, Dolby TrueHD, Dolby E, and Dolby Pro Logic® II technologies. It
also supports advanced Dolby technologies, such as associated audio mixing.
The DP580 provides a real-time reference tool for generating signals for Dolby TrueHD,
Dolby Digital, and Dolby Digital Plus. It also enables validation of associated
Metadata-enhanced Audio Transmission (MAT) encoded Dolby TrueHD signals. These
features enable consumer and professional device manufacturers to use the DP580 to test
the integration of Dolby technologies in their products.
The DP580 offers comprehensive monitoring and quality control (QC) through a
web-based user interface that provides easy selection and monitoring for downmixing,
listening, and compression modes. Front-panel controls also allow selective monitoring
through standard headphones.
Extensive input capabilities allow broadcasters to perform QC at any point within their
headend. This enables monitoring and display of all audio-related metadata as well as
measuring program loudness, using Dolby Dialogue Intelligence™ technology with ITU-R
BS.1770-1, ITU-R BS.1770-2, ITU-R BS.1770-3, and Leq(A) loudness estimation. The DP580
also supports EBU loudness.
Dialogue Intelligence features an advanced measurement technology capable of
quantifying the subjective loudness of speech in broadcast programming. We developed
this technology to analyze the input signal and make measurements only when dialogue
is present. Quantifying the dialogue level simplifies a crucial step in broadcasting. When
switching between programs, most home listeners adjust their television volume controls
in an effort to achieve consistency in dialogue levels between programs. By properly
monitoring the dialogue level, you can verify whether the Dolby dialogue level metadata
parameter is accurate.
The DP580 provides these additional features:
•
Monitoring capabilities for broadcaster QC set-top box (STB) labs
•
A consumer emulation mode for Dolby Digital Plus and Dolby Pulse decoders found
in consumer TVs and STBs, as well as H.264 and MPEG-2 video decoding
•
High-Definition Multimedia Interface™ (HDMI™) 1.4a I/O compatibility
•
HDMI Extended Display Identification Data (EDID) device emulation (emulates
HDMI repeater/sink device: audio/video receiver [AVR], TV, STB)
•
Error detection and information logging (pause burst, IEC 61937 data types,
Consumer Electronics Control [CEC] message)
•
HDMI Audio Return Channel (ARC) support
•
HDMI pass-through mode

Dim Button
Reduces the audio level by a configurable value. (Default is –20 dB.) You can configure this
attenuation control through the Monitoring screen. When you press this button to activate
the current dim setting, its LED illuminates in red.
Over-Temperature LED
This LED blinks in red when the CPU temperature approaches the maximum temperature
specified by the manufacturer (or if an internal fan fails). If this occurs, verify that the
ambient temperature is within the DP580 operating temperature limits (10°C to 35°C) and
there is proper airflow to the DP580 front-panel vents. If the red LED blinks in red because
an internal fan fails, the other fans operate at their highest speed, which is audible.

Installing the Hardware
To install the DP580:
1.
Rack mount the DP580 in a 1-U rackspace. The DP580 measures 44 × 483 × 394 mm
(1.75 × 19 × 15.5 inches), so the rack must be at least 16 inches deep.
Caution: To ensure proper ventilation, do not block the front-panel ventilation area (above
the Dolby logo).
2.
Connect your video outputs and inputs:
HDMI
•
Connect one end of an HDMI™ cable to the DP580 HDMI OUT port. Then connect
the other end of the cable to the HDMI input on a compatible receiving device.
•
Connect one end of an HDMI cable to the DP580 HDMI IN port. Then connect the
other end of the cable to the HDMI output on a compatible source device.
ASI/SDI
•
3.
Connect one end of an ASI/SDI cable to the DP580 ASI/SDI IN port, and connect
the other end of the cable to a compatible output device.
Connect your audio inputs and outputs:
Digital Audio
•
Connect one end of a high-density BNC cable to the AES IN port. Then connect the
other end of the cable to the standard BNC cable attached to your external digital
audio outputs.
•
Connect one end of a high-density BNC cable to each of the four AES OUT ports.
Then connect the other end of the cables to a standard BNC cable attached to your
external digital audio inputs.

Compression Mode
Compression Mode provides four options: None, Line, RF, and Auto.
You can enable a compression option only when the unit is decoding a Dolby signal.
RF applies the strongest compression profile available, equivalent to an RF connection to a
TV set or small speakers.
Line applies what some consumer decoders call light compression; this is usually the
default setting for DVD players and STBs. In this mode, you can control the compression
Cut and Boost settings.
With the exception of Dolby TrueHD, Auto mode scales the Line mode profile, based on the
Compression Cut and Compression Boost settings. Auto is a separate mode for Dolby
TrueHD, in which the compression settings are based on the metadata.
None applies only the dialogue normalization parameter (dialnorm), but no dynamic
range compression.
Note:
When downmixing, the DP580 automatically applies enough compression at peak
moments to prevent signal overload, even when a compression mode is not
selected.
Compression Mode Line Settings
The Line mode compression settings define cut and boost scaling factors when the
Compression Mode is set to Line. When downmixing, any scaling defined for the cut factor
is ignored, and the system applies the full cut dynamic range compression. The factory
setting for Line is 0. At that setting, selecting Line turns dynamic range compression off.
To customize your compression settings:
•
Click Line for Compression Mode.
The Compression Cut and Compression Boost fields are now active. When you click on
either of these fields, the corresponding drop-down menu is displayed, as shown in
Figure 2-29 for Compression Cut. Both of these drop-down menus display the same
options.

Stereo Downmix Mode
Stereo Downmix Mode specifies how the Dolby Digital, Dolby Digital Plus, AAC,HE AAC,
and Dolby E decoders perform stereo downmixing when the Decoder Output mode is set
to 2/0. When you click the Stereo Downmix Mode field, a drop-down menu is displayed, in
which you can select from three stereo downmixing options: Auto, LtRt, or LoRo.
Following is a description of each Stereo Downmix Mode option:
•
Auto follows the preferred downmixing instructions specified in the bitstream
metadata.
•
Lt/Rt produces an output compatible with Dolby Surround Pro Logic decoding. It is a
two-channel signal that is similar to a program encoded as Dolby Surround. A
properly encoded Dolby Digital program includes metadata that controls downmix
delivery, so if a user has a Dolby Pro Logic system, but not Dolby Digital, the program
plays back taking full advantage of Dolby Pro Logic. Program metadata also
customizes downmix delivery for a stereo system. Lt/Rt enables the Dolby Pro Logic
decoder to convert a two-channel downmixed stream back to its original
configuration (for example, back to Dolby Digital 5.1).
•
Lo/Ro outputs only two channels (for example, a headphone output stream), but with
this type of downmix you cannot convert the stream back to 5.1. We recommend that
program mixers designate Lo/Ro as the source for mono downmixes. However, a
mono output of the Lt/Rt mix is also possible.
•
For correct emulation of consumer products, the LFE channel is discarded in Lt/Rt and
Lo/Ro downmixing modes, except when LFE mix level metadata is present in the
content.
Note:
28
Both Lt/Rt and Lo/Ro output to the Left and Right channels. If you apply Dolby Pro
Logic decoding, the decoded output is sent to Left, Right, Center, and a mono
surround channel output, which is then sent to both the Left surround and Right
surround outputs to feed both surround speakers.

Metadata Emulation
Check this box if you want the Dolby E decoder to apply the metadata parameters to
baseband PCM audio. This emulation function eliminates the encode/decode cycle,
allowing you to preview the effects of downmixing, setting dialogue level, Dolby Pro Logic
decoding, and the other functions controlled by metadata and experienced by consumers.
Dolby E Latency Mode
Dolby E Latency Mode provides two options for decoding Dolby E bitstreams: Lenient Mode
and Strict Mode. In Lenient Mode, the system absorbs Pa spacing errors in up to 130 samples
before performing a correction, which results in many inaudible errors. However, this may
result in latency inaccuracies in up to 130 samples. In Strict Mode, the system corrects all Pa
spacing errors and the system always maintains the correct latency.

Dolby Pro Logic IIx Mode
When you select the Dolby Pro Logic IIx Mode field, the corresponding drop-down menu is
displayed.
Dolby Digital EX
Dolby Digital EX is electrically equivalent to Dolby Digital combined with Dolby Pro Logic
IIx Movie mode with 6.1-channel outputs. However, to maintain continuity with current
products and with Dolby Digital Surround EX™ content, it continues to be known as Dolby
Digital EX. We do not recommend the use of a single Cb speaker in any system. Ideally, the
product has a 7.1-channel output capability to readily support Ls, Lb, Rb, and Rs speakers.
When a 7.1-channel product is in Dolby Digital EX mode, the Cb signal is divided equally
(after being attenuated by –3 dB) to the Lb and Rb speakers.
Music Mode
Music mode allows users to obtain optimal results from conventional stereo programs. If a
program was produced in Dolby Surround, it is ideally decoded with Movie mode, even
when the program is music oriented.
Movie Mode
Movie mode allows users to obtain optimal results from both surround-encoded programs
and conventional stereo programs. In addition, Movie mode offers greater spatial
capabilities than 6.1 type decoders, including Dolby Digital EX. As a result, we recommend
this mode for decoding Dolby Digital Surround EX soundtracks.
Dolby Pro Logic II Mode
When you select the Pro Logic II Mode field, the corresponding drop-down menu is
displayed.
Music Mode
Music mode is the most versatile Dolby Pro Logic mode. It activates the settings on the
Panorama Mode, Dimension, and Center Width menus; these settings can help users
optimize a stereo (Lo/Ro) automotive entertainment environment or home theater system
for multichannel listening.

•
Panorama Mode sends the stereo signal to the Left and Right speakers, as well as the
surround speakers. This mode is not functional if Music is not selected in the Pro Logic
II Mode drop-down menu.
•
Dimension refocuses the signal from the front speakers to the rear speakers. If Music is
not selected in the Pro Logic II Mode drop-down menu, the system sets the Dimension
mode to 0 (Center).
•
Center Width splits the Center output signal into the Center, Left, and Right outputs. If
you set this mode to -3, the system sends all of the Center output to the Center
channel. If you set this mode to L/R, the system outputs equally to the Left and Right
channels, with no output sent to the Center channel.
Movie Mode
The standard setting for programs with video. This mode is based on the original Dolby
Pro Logic decoding scheme, but the system separates the mono Surround channel into Left
Surround and Right Surround channels.
Dolby Pro Logic Mode
Reproduces the original Dolby Pro Logic decoding system. Because consumer decoders
now offer Dolby Pro Logic II as the default Dolby Surround decoding system, this
emulation mode is available to reproduce the original Dolby Pro Logic decoding if the
consumer wishes to hear it. (This option is not available on all consumer decoders made
with Dolby Pro Logic II.)
Matrix Mode
Optimizes radio reception in an automotive environment. This mode is similar to the
original passive Dolby Surround decoder without Dolby Pro Logic directional steering. It
can also enhance mono programs, and clean up weak radio signals in automobiles. You can
apply Matrix to a mono input by selecting the applicable Lo/Ro downmix mode, and then

Associated Audio Mixing
A Dolby® Digital Plus™ input may include one or more (maximum of seven) associated
audio streams. The Dolby Digital Plus decoder can mix the main audio stream with any
available associated audio stream, as specified for Digital Video Broadcasting in Annex E
of ETSI TS 101 154. The system transmits a descriptive track as a separate bitstream
alongside the main soundtrack and can mix the tracks within the decoder. The associated
audio stream and the main audio stream can reside in a single PID or in separate PIDs.
This associated audio mixing approach can deliver directors’ commentaries or audio
descriptions for the visually impaired while maintaining the highest possible bandwidth
efficiency. Associated audio mixing eliminates the need to prepare and transmit multiple
final mixes to support different audience needs and preferences. The Dolby Digital Plus
metadata specifies the audio level for associated audio mixing.

Dolby E Decoding Behavior
The Dolby® DP580 supports reference decoding of Dolby E over AES, ASI/SDI, and
transport streams through SMPTE 302M. The system performs the following functions:
•
4.1
Monitors multichannel audio (one program at a time from a Dolby E stream)
•
Monitors two-channel audio from the selected Dolby E program
•
Displays Dolby E metadata for all programs
•
Emulates Dolby E metadata for multichannel output (configurable) and two-channel
output
Dolby E Program Selection
The DP580 enables you to select a single program to monitor from a Dolby E stream. For
example, if the Dolby E program configuration is 5.1+2, you can listen to the 5.1-channel
program (program 1) or the two-channel program (program 2). By default, program 1 is
always selected when monitoring a new Dolby E stream.
The AES, HDMI, and multichannel analog outputs reflect the currently selected program.
The headphone always provides a confidence downmix of the currently selected program.
If you specify Downmix or Dolby Digital for the output configuration, the system routes a
two-channel downmix of the currently monitored program to that output.
4.2
Dolby E Metadata Emulation
The DP580 provides an option that allows you to emulate the effects of the Dolby Digital
encode/decode process, which simulates the end-user listening experience. The emulation
process performs the following:
•
Application of dialogue normalization
•
Dynamic range control computation and application
•
Worst-case downmix level calculation to prevent clipping
•
Downmixing with metadata application
Metadata emulation is enabled or disabled as specified in the respective configuration.
