HD for the Hearing, Sight Impaired
Harris Corporation and NPR will demonstrate new uses for HD Radio: The broadcaster and the equipment maker say that at NAB2006, the broadcasters trade show, they will show captioned text for the hearing impaired and radio reading services for the visually impaired. They will show the chain of equipment and services, from injection of this material into an HD Radio multicasting stream down to reception using Kenwood and Boston Acoustics radios. Public radio stations have been particularly interested in rolling out these services as part of their overall HD Radio plan.
Some public radio stations use analog subcarriers, which offer inferior audio quality to regular AM and FM, to provide 1,000,000 weekly listeners with Radio Reading Services for the Blind.
