The Dolby MS11 decoder is certified by Dolby Laboratories to run on single and dual-core ARC audio processors; it supplies full Dolby metadata support and decodes all audio formats required to match global and local broadcast standards including Dolby Digital Plus, Dolby Digital and Dolby Pulse; and it allows pass-through of the main audio directly for output over HDMI interfaces.
The Dolby MS11 Multistream Decoder is optimised for DesignWare ARC AS211SFX and AS221BD audio processors, providing television and set-top box manufacturers with a single-package technology solution for decoding all premium audio formats including Dolby Pulse AAC LC, HE AAC, and HE AAC v.2. With Dolby Laboratories’ certification for the ARC AS2xx family of single and dual-core audio processors, Synopsys offers a complete and proven solution that simplifies the development, testing and qualification of Dolby MS10/MS11-enabled devices while ensuring optimal compatibility with the worldwide installed base of home theatre systems and future broadcast audio standards.
Synopsys’ DesignWare ARC audio solution is a scalable hardware and software IP solution that includes codecs, audio processors, media streaming frameworks and post-processing software. The Dolby MS11 decoder for ARC can be used on either a single-core AS211SFX or dual-core AS221BD ARC audio processor, which gives designers the flexibility to configure designs for specific applications and performance requirements. ARC audio processors incorporate dual MAC (Multiply-Accumulate) execution units for efficient audio processing, resulting in a processor load as low as 56 MHz for 100 cycles of latency from system memory and leaving sufficient bandwidth for additional audio software. Additionally, the ARC-optimised Dolby MS11 decoder enables a wide range of post-processing capabilities by including full access to the decoded audio streams. One key application is the ability to apply Dolby Volume to a decoded 5.1 Dolby Digital Plus stream and then re-encode the stream to Dolby Digital for output to a home theatre.
