Dynamic Resolution Adaptation (DRA) was an audio encoding specification developed by DigiRise Technology. It had 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 was 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 were no discs released with DRA audio, though there were expected to be such discs for the Chinese market but did not happen.
