The Blu-ray Disc Association announced on Wednesday in Beijing that DRA (Dynamic Resolution Adaptation) technology, a digital audio coding standard to which China owns intellectual property rights, has been included in the 2.3 specifications for the BD-ROM format as an optional encoding and decoding technology for the Blu-ray Disc format.

DRA technology was independently researched and developed by Guangzhou Digital Rise Technology, and in August 2007 the China Hualu Group formally proposed the technology to BDA. DRA technology was finally approved formally after two rounds of technical evaluations by the BDA in the US and Japan.

This marks China's establishment of a share in the international Blu-ray Disc standard system, a shift from the long-run dominance of foreign companies over technologies in this field.

At present, besides being used in daily applications such as digital TV, MP3 players and online multimedia, DRA audio standards will be used in the areas of live satellite TV, digital cable TV, Blu-ray Disc players and Blu-ray Discs, where breakthroughs in manufacturing will be achieved.
