Content-encoding solution providers will use Dolby Digital Plus technology to enable high-quality multichannel audio for the Digital Entertainment Content Ecosystem (DECE) UltraViolet platform through the UltraViolet Common File Format (CFF).

UltraViolet enables consumers to create personal digital entertainment collections, with the freedom to access their content both at home and on the go across multiple devices. The UltraViolet CFF makes download functionality consistent across all UltraViolet retailers, which makes it easy for consumers to move or copy downloaded files directly across UltraViolet-compliant devices or applications, without the need for additional downloads or bandwidth.

"DECE is built on the efforts of the most innovative and forward-thinking companies in digital entertainment. Dolby has worked on the early verification and refinement of the Ultraviolet Common File Format technical design as well as investing to help establish and complete the testing and verification process for Dolby Digital Plus encoded CFF files," said Mark Teitell, General Manager and Executive Director, DECE. "We welcome and appreciate Dolby's contributions to the process and are excited to be working together on UltraViolet."

Dolby is working with companies such as castLabs, Digital Rapids, and Elemental Technologies to ensure that UltraViolet content plays well on many services and devices that matter to consumers.

Dolby also announced the availability of a development kit to support the use of Dolby Digital Plus in the UltraViolet CFF specification. The latest development kit includes test vectors to support companies developing products and services based on the UV CFF specification. Today's update complements previous development kits to support the use of Dolby Digital Plus in the MPEG Dynamic Adaptive Streaming over HTTP (MPEG-DASH), Apple HTTP Live Streaming (HLS), and Microsoft Smooth Streaming online delivery systems.
