2.1.1 Dolby AC-4 features
The key aspects of Dolby AC-4 highlight the improvements and expanded user experiences that
the product brings to the broadcast environment. The list provided here does not cover all
aspects of Dolby AC-4. For a complete description, refer to the respective specifications (ETSI TS
103 190-1 for channel-based audio and ETSI TS 103 190-2 for immersive and personalized audio).
Summary of Dolby AC-4 features:
Improved compression efficiency
•
Compared to Dolby Digital and Dolby Digital Plus, Dolby AC-4 provides significantly better
compression efficiency and better audio quality at a fixed bit rate or the same audio quality
at a lower bit rate.
Dolby AC-4 provides the same industry-standard, multichannel 5.1 audio quality as Dolby
Digital Plus at half the data rate, which means multichannel audio can be encoded using 96
kbps.
Support for Dolby Atmos content
•
Provides tools to process the newest generation of object-based audio content.
Overview of the Dolby Professional Reference Decoder DP580
Personalization
•
Provides tools for users to personalize their listening experience.
Built-in, metadata-based multichannel and multiband dynamic range and loudness control
•
as well as integrated postprocessing
Advanced dynamic range compression is known from Dolby Digital and Dolby Digital Plus.
Dolby AC-4 improves the audio quality further by using multiband and multichannel
compression algorithms compared to the original method, which used a single wideband
gain factor for all channels.
Dolby AC-4 dynamic range control supports the transmission of user-selectable dynamic
compression parametric curves and compression gains for more flexibility and wider
support.
Support for the newest generation of consumer playback devices to adapt the content to
•
specific listening environments and playback scenarios such as:
Audio/video receiver and home theater
•
Portable/mobile speakers
•
Portable/mobile headphones
•
Flat-panel TV
•
Advanced dialogue enhancement
•
Provides a better experience to users with hearing impairments.
Built-in audio/video (A/V) frame alignment
•
Dolby AC-4 supports frame sizes that enable alignment of audio frames with most popular
video frame sizes. This feature can be used to circumvent one of the common sources for A/V
synchronization problems (also referred to as digital turnaround).
Excellent audio quality for legacy content configurations
•
Integrated headphone virtualization and support for immersive stereo decoding
•
Speaker virtualized output
•
Immersive (5.1.2) channel-based output

2.1.2 Dolby Atmos
Dolby Atmos is an object-based audio technology for creating and reproducing spatial audio.
The Dolby Atmos platform encompasses products, services, and technologies and includes
authoring, distribution, and playback tools for both linear and nonlinear content.
Rather than require a content creator to downmix the individual elements (objects) of an audio
scene to a fixed number of output channels prior to transmission and rendering, individual
audio objects can be preserved, transmitted, and rendered individually. Key features of
Dolby Atmos include:
Object-based audio metadata encoded in the audio bitstream
•
Three-dimensional audio rendering
•
Device-independent audio bitstreams that can be faithfully rendered by any Dolby Atmos
•
playback device
A flexible rendering engine for Dolby Atmos playback devices that supports a wide range of
•
loudspeaker layouts and room characteristics
New speaker positions and designs
•
Overview of the Dolby Professional Reference Decoder DP580
Dolby Atmos supports dynamic objects as well as traditional channel-based audio. Dynamic
objects are used for discrete sound elements that can be precisely placed and moved through
the playback environment, such as a helicopter that flies over the audience. Channel-based
audio is often used for static ambient sounds, such as the music portion of a soundtrack. A
typical Dolby Atmos soundtrack is a combination of dynamic objects and bed objects (channels)
collectively referred to as object-based audio.
2.1.3 Dolby Digital Plus features
Dolby Digital Plus introduces a number of enhancements to Dolby Digital, including support for
a wider range of data rates, increased channel count, multiple-program support, and additional
tools for representing compressed data and eliminating artifacts. Dolby Digital Plus is backward
compatible with Dolby Digital.
Dolby Digital Plus includes these features:
High data rate
Supports a maximum data rate of 6,144 kbps.
Uses a variable frame duration (one, two, three, or six audio blocks per frame) to
accommodate high data rates.
Scalable bitstream structure
A flexible structure of multiple independent and dependent substreams supports additional
programs and additional channels.
Multichannel support
Supports up to 7.1.4 channels in a single program and up to two independent LowFrequency Effects (LFE) channels.
Multiple audio programs
A single bitstream can contain up to eight audio programs.
Mixing metadata
A bitstream can carry mixing metadata for receiver mixing of two streams (for example, to
support service).
Dolby Professional Reference Decoder DP580 v2.0 user's guide
16 January 2018 9
Encoding tool and conversion metadata
A bitstream contains metadata generated by coding tools as well as metadata values that
enable a decoder to convert a Dolby Digital Plus bitstream to Dolby Digital without fully
decoding it.
Multiple downmix options
A bitstream can carry downmix coefficients for stereo, Dolby Surround compatible, and
Dolby Pro Logic II compatible downmixes.
2.1.4 Dolby Digital features
Because Dolby Digital Plus is built on Dolby Digital, they share a number of features.
These Dolby Digital features are also part of Dolby Digital Plus:
Dialogue normalization
Dialogue normalization is the process of aligning the average dialogue level of different
programs to a consistent level (the dialogue reference level) so that a consumer does not
have to constantly adjust the volume control of the playback system as programs change.
Dynamic range control
Dynamic range control compresses the dynamic range of a program by reducing (cutting)
the level of the loudest sounds and increasing (boosting) the level of the quietest sounds to
adjust the sound to the listening situation.
Overview of the Dolby Professional Reference Decoder DP580
Audio production information
Audio production information is additional information about the audio production
environment, such as the mixing level, recording room type, and copyright information.
Dolby Digital also supports two types of two-channel downmix: Dolby Surround compatible
(Lt/Rt) and stereo (Lo/Ro). In Dolby Digital decoders, when 2.0 output is selected and LFE output
is disabled, the LFE channel content is not reproduced.
2.1.5 Dolby ED2 features
Dolby ED2 extends Dolby E in many dimensions. The expanded capabilities enable greater
broadcast flexibility and better end-user experiences.
Dolby ED2 includes these features:
Greater number of AES3 stereo pairs
The maximum number of pairs is increased from two to four.
Greater number of audio elements (channels or objects)
The maximum number of elements is increased from 8 to 16.
Different use for program configurations
Dolby E provides 24 channel-based configurations, whereas Dolby ED2 configurations are
restricted for personalized and immersive use cases.
Dolby E and Dolby AC-3 metadata parity
Metadata for both the contribution format and the codec remain accessible.
2.2 New features
This release of the Dolby Professional Reference Decoder DP580 adds new functionality
included with the latest Dolby codecs and contribution formats. Later releases may carry
additional functionality for broadcast environments.
