Broadcasting) The digital radio standard in most countries except for the U.S., which uses iBiquity's HD Radio, and Japan, which uses Terrestrial Integrated Services Digital Broadcasting (ISDB-T). Developed by the Eureka 147 Project in Europe, DAB uses frequencies from 175 to 239 MHz and 1.45 to 1.49 GHz. DAB+, which is backward compatible with DAB, is based on the aacPlus Version 2 digital audio standard (see
