Dolby debuts audio description service for HDTV

September 30, 2010

At IBC2010, Dolby Laboratories demonstrated HDTV-compatible audio description services enabled via Dolby Digital Plus. The Dolby solution allows visually impaired viewers to enjoy HDTV surround-sound programming with optional audio descriptive tracks.

Using STMicroelectronics’ advanced STi7108 single-chip set-top box solution, the demonstration showed how Dolby Digital Plus can enable the main surround soundtrack and an additional commentary track to be carried together as a single, bandwidth-efficient bit stream.
