The Dolby MS11 and MS12 Multistream Decoders provide TV, set-top box, and IC manufacturers with a single-package solution for decoding all premium broadcast audio formats.
Decodes all audio formats required to match worldwide and specific local broadcast standards: Dolby® Digital Plus™, Dolby Digital, HE AAC, and all AAC bitstreams. Dolby MS12 also supports next-generation audio experiences via Dolby AC-4.
Supplies full Dolby metadata support for Dolby Digital Plus, Dolby Digital, and the Dolby implementation of HE AAC v2 audio formats.
Generates standard Dolby Audio™ bitstreams, up to 5.1 channels (Dolby MS11) or up to 7.1 channels (Dolby MS12) from any incoming audio format; creates standard two-channel downmix.
Delivers audio description services in receiver-mix style, using two simultaneous decoders, so broadcasters can transmit a single mix.
Transcodes the input signal to deliver a 7.1- or 5.1-channel Dolby Digital Plus bitstream over S/PDIF, HDMI®, or Wi-Fi connection, ensuring your customers get the sound that best matches their systems.
Provides volume leveling for all audio formats, across programs and channels. Dolby MS12 adds bass enhancement, speaker tuning, virtual surround, and speech-gated dialogue enhancement and Intelligent loudness.
As TVs and set-top boxes evolve into multipurpose digital media platforms, you face a manufacturing challenge. Content now comes from a variety of sources—and this results in a variety of audio codecs. Yet consumers expect a seamless experience whether they're watching traditional broadcast or streaming from the Internet, PCs, USB keys, game consoles, or mobile devices.
The Dolby Multistream Decoders, MS11 and MS12, deliver the solutions. Comprehensive and cost-effective, they reduce the complexity of integrating multiple audio technologies into your new receivers.
The Dolby MS11 and MS12 also feature Dolby Volume, so consumers enjoy consistent volume levels across programs and sources. Although Dolby metadata includes dialnorm parameters, many sources don't include Dolby metadata, so loudness levels may vary widely. Dolby Volume provides a solution that keeps your customers happy.
By including full access to the decoded bitstreams, the Dolby MS11 opens up a whole range of postprocessing opportunities. It can apply Dolby Volume to a decoded 5.1 Dolby Digital Plus input stream and then reencode the stream to Dolby Digital for output to a home theater.
Other postprocessing applications can include virtual surround sound processors and custom equalization of the audio to maximize loudspeaker performance. Additionally, the Dolby MS11 provides explicit testing and support for file playback of ASF and MP4 containers.
The Dolby MS12 further expands postprocessing capabilities. Intelligent Loudness provides ITU-R relative and speech-gated loudness control and regulatory information for automated loudness management. For TV receivers, the Dolby MS12 can improve the sound of the small built-in TV speakers with enhanced bass response, speaker tuning for optimum performance, and virtual surround sound.
Other new features of the Dolby MS12 include automatic pass-through of Dolby Digital Plus signals with the Dolby Atmos extensions and speech-gated Dialogue Enhancement so your customers hear every word.
The Dolby MS11 and MS12 include licenses for the included Dolby technologies at a lower overall cost than separate licenses for existing Dolby Digital Plus, Dolby Digital, HE AAC, AAC, and transcoder options.
With their universal capabilities, the Dolby MS11 and MS12 also simplify product development and testing. Dolby supplies you with all the deliverables, testing, and technical support you need to make implementation easy.
