Dolby Multistream Decoder MS12

Dolby Multistream Decoder MS12

The Dolby Multistream Decoder MS12 provides TV, set-top box, and IC manufacturers with a single-package solution for decoding all premium audio content worldwide—broadcast, file-based, OTT/VOD services, and pay-TV operators.

  • Decodes all audio formats required to match worldwide and specific local broadcast standards: Dolby Digital Plus™, Dolby® Digital, HE- AAC, all AAC bitstreams, and Dolby AC-4.

  • Supplies full Dolby metadata support for Dolby AC-4, Dolby Digital Plus, Dolby Digital, and the Dolby implementation of HE AAC v2 audio formats.

  • Generates standard Dolby Audio™ bitstreams up to 7.1 channels 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, with end-to-end, metadata-based Intelligent Loudness. The Dolby MS12 also supports bass enhancement, speaker tuning, virtual surround, and speech-gated dialogue enhancement.

Meeting the Challenge of Decoding Multiple Audio Formats

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 and PCs, or getting content from USB keys, game consoles, or mobile devices.

The Dolby Multistream Decoder MS12 delivers the right solution. Comprehensive and cost-effective, it reduces the complexity of integrating multiple audio technologies into your receivers.

The Dolby MS12 also provides a consistent volume level across programs and sources to make listening more enjoyable. Although Dolby metadata includes dialnorm parameters, many sources don't include it, so loudness levels may vary widely. The Dolby volume-leveling technology provides a solution that keeps your customers happy.

With available support for Dolby AC-4, Dolby MS12 also paves the way for next-generation audio experiences, so you'll be ready for future developments like ATSC 3.0 in the United States.

Another important Dolby MS12 feature is native support for advanced audio use cases from Netflix. Netflix partners can find more information in the the Netflix Ready Device Platform SDK.

 

Extensive Postprocessing Capabilities

The Dolby MS12 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 Dolby Atmos® extensions and speech-gated Dialogue Enhancement, so your customers hear every word.

 

Cost-Effective

The Dolby MS12 includes licenses for the included Dolby technologies at a lower overall cost than separate licenses for existing Dolby Digital Plus, Dolby Digital, and transcoder options.

With universal capabilities, the Dolby MS12 also simplifies product development and testing. Dolby supplies you with all the deliverables, testing, and technical support you need to make implementation easy.
