As dependent substreams have the same structure as independent substreams, each dependent substream may contain up to five full-bandwidth channels and one low-frequency channel however these channels may be assigned to different speaker placements. Dependent substreams, which contain additional channels beyond the traditional 5.1 channels.At most a single legacy substream may be present in a DD+ stream. Legacy substreams, which contain a single 5.1 program, and which correspond directly to Dolby Digital content.The channels present in an independent substream are limited to the traditional 5.1 channels: Left (L), Right (R), Center (C), Left Surround (Ls), and Right Surround (Rs) channels, as well as a Low Frequency Effects (Lfe) channel.

Up to eight dependent substreams may be present in a Dolby Digital Plus stream.

Independent substreams, which can contain a single program of up to 5.1 channels.

Number of audio programs per bitstream: 8ДЄ Dolby Digital Plus service consists of one or more substreams.

2.3 Consumer broadcast in digital television systems.

2.2 Physical transport for professional devices and applications.2.1 Physical transport for consumer devices.2 Encapsulation, use, and storage of Dolby Digital streams.1.5 Relation to Dolby Digital and Dolby Atmos.1.4.1 Modified discrete cosine transform.1.3.1 Storage of transform coefficients.The full set of technical specifications for E-AC-3 (and AC-3) are standardized and published in Annex E of ATSC A/52:2012, as well as Annex E of ETSI TS 102 366 V1.2.1 (2008вЂ“08), published by the Advanced Television Systems Committee. While Dolby Digital (AC-3) supports up to five full-bandwidth audio channels at a maximum bitrate of 640В kbit/s, E-AC-3 supports up to 15 full-bandwidth audio channels at a maximum bitrate of 6.144 Mbit/s. It is a successor to Dolby Digital (AC-3), also developed by Dolby, and has a number of improvements including support for a wider range of data rates (32В kbit/s to 6144В kbit/s), increased channel count and multi-program support (via substreams), and additional tools (algorithms) for representing compressed data and counteracting artifacts. Dolby Digital Plus, also known as Enhanced AC-3 (and commonly abbreviated as DD+ or E-AC-3, or EC-3) is a digital audio compression scheme developed by Dolby Labs for transport and storage of multi-channel digital audio.
