The Blu-ray Disc Association (BDA) 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.
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.
The Blu-ray Disc is considered the product that will replace the DVD with its huge storage capacity and high-definition AV quality.
In 2002, nine companies including Sony, Philips and Panasonic released the Blu-ray standards, and established BDA in 2004. With over 180 member enterprises including Apple, Dell, Hewlett-Packard, Hitachi and Warner Bros., BDA has become the world’s most influential developer and promoter of disc format standards.
At present, besides being used in daily applications such as digital TV, MP3 players and online multimedia, according to relevant plans of China, 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 industrialization will be achieved.
