Dynamic Resolution Adaptation

Audio codec standard

Dynamic Resolution Adaptation (DRA) is an audio encoding specification developed by DigiRise Technology. It has been selected as the Chinese national audio coding standard,[1] and declared suitable for China Multimedia Mobile Broadcasting and DVB-H as addressed in the International Journal of Digital Multimedia Broadcasting.

The format is recognised by the CTA EDID Timing Extension Block standard (used by many A/V interfaces) and the Blu-ray Disc specification, introduced with Blu-ray Disc 2.3.[2] There are no discs as yet released with DRA audio,[needs update] though there are expected to be such discs for the Chinese market.
