"Sony has announced that in addition to the updated interface of its PlayStation Store, the latest version of its PlayStation 3 firmware will add DTS-HD Master Audio and DTS-HD High Resolution Audio features for Blu-ray movies.

Sony says the new audio features will give users the "complete high-definition Blu-ray movie experience, matching the format’s crisp visuals with rich, lifelike sound."

DTS-HD Master Audio delivers audio at 24.5 mega-bits per second (Mbps) significantly higher than standard DVDs, and 7.1 audio channels at 96k sampling frequency/24 bit depths. Sony says more than 100 Blu-ray movies and concert videos feature DTS-HD Master Audio.

The company also says the DTS-HD High Resolution Audio codec gives content creators the ability to stream audio at a high constant bit rate of 6.0 Mbps on Blu-ray discs, and is also capable of up to 7.1 audio channels at 96k sampling frequency/24 bit depth resolution.

In addition to the audio features, the new update will also bring the newly revamped PlayStation Store, transitioning the feature from an online storefront to a native PS3 application, which Sony says will enable customers to "more easily and quickly locate and purchase games, and download demos, game videos, Blu-ray movie trailers and other game-related content for PS3.""
