DVDs, regional coding and music

摘要

The audio world has so far been spared the misery of regional coding, the much-hated system that stops a DVD disc playing in another country. But this could all change. At CES in Las Vegas the two rival blue laser tems Blu-ray and HD-DVD were both promising to launch this Spring or Summer. Because blue laser will offer the highest resolution audio yet, with more channels than ever before, there is a risk that any regional coding used by blue laser will start to obstruct music releasing as well as movies.
