Digital Audio Broadcasting (DAB) is a digital method of transmitting virtual CD quality audio signals to radio receivers. In-Band On-Channel Digital Audio Broadcasting (IBOC DAB) is a broadcasting technology that uses the current radio spectrum to transmit existing AM and FM analog simultaneously with new high-quality digital signals, which eliminate multipath and noise, and reduce interference. This technology provides a unique opportunity for broadcasters and listeners to convert from analog to digital radio without service disruption while maintaining current dial positions of existing stations. Broadcasters will use their current AM and FM frequency assignments to transmit simultaneous analog and digital high-quality audio, in addition to expanded auxiliary services. Listeners who purchase digital radios will receive their favorite radio stations with superior sound quality free from multipath and noise, and with reduced interference. Additionally, listeners will have the capability to receive expanded auxiliary data services, such as station and program content, stock and news information, local traffic and weather, email and internet access, and more.
