Dynamic Resolution Adaptation

This article needs to be updated. Please help update this article to reflect recent events or newly available information. (March 2024)

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.
