DAB acrescenta AAC ao formato de conversão MPEG

«World DMB, an international organization for the development and deployment of Eureka 147-based digital mobile broadcasting technologies, has released details of its plans to create optional audio coding for DAB. The organization has submitted a draft of technical specification tiled "Digital Audio Broadcasting (DAB); Transport of AAC Audio" to the international standard body ETSI. World DMB-compatible receivers and broadcast services supporting the new standard may be introduced as early as 2007. A marketing task force has been set up to develop a consumer-friendly name for the effort. Eureka 147 currently uses MPEG Layer II to encode streams. By adding ACC as an optional algorithm, more stations can be broadcast on a given multiplex signal for more spectrum efficiency. It's expected that the change will also lower transmission costs for digital stations. New receivers with ACC will be backward compatible with the existing codec standard. Current MPEG Layer II services and consumers will be unaffected by the change. »
