Hmm.. well it looks like the Playstation 3 will be getting 5.1 Dolby Digital Plus on October 18th and then more devices will be added at a later date.
"Netflix is committed to delivering an unparalleled experience to its members who watch TV shows and movies streamed instantly over the Internet," said Greg Peters, Netflix vice president of product development. "Netflix required an audio solution that could efficiently deliver an outstanding surround sound experience for a wide range of consumer devices. Dolby Digital Plus proved to be the best solution to meet our needs and the needs of our device partners."
Dolby Digital Plus supports up to 7.1 channels of premium-quality surround sound and allows consumers to enjoy outstanding high-definition audio from broadcasts, streaming and downloaded media, and Blu-ray Disc™. To date, tens of millions of TVs, set-top boxes, Blu-ray Disc players, Audio/Video receivers, and mobile phones have shipped with Dolby Digital Plus.
"Dolby Digital Plus makes the online entertainment experience rich, realistic, and memorable," said John Couling, vice president, marketing, products & platforms, Dolby Laboratories. "Dolby is excited to be working with Netflix and its partners to provide premium Dolby surround sound to Netflix subscribers. This collaboration will enable subscribers to enjoy movies and TV shows presented in surround sound just as the artists and directors intended."
Dolby Digital Plus is a sophisticated audio system based on Dolby Digital that has been adopted by many of the world’s leading broadcasters, TV and set-top-box manufacturers, and device makers to provide consumers with full digital surround sound. It is designed to adapt to the changing demands of entertainment delivery while retaining compatibility with existing Dolby Digital 5.1-channel home theater systems.
