Santa Ana, CA (July 1, 2004)–SRS Labs, Inc. and iBiquity Digital Corporation have announced the completion of the joint testing of SRS Circle Surround technology as a compatible surround sound format for iBiquity’s HD Radio broadcast technology. HD Radio technology is the digital broadcasting system for terrestrial radio, and is the only digital technology authorized by the FCC for broadcasting in the AM and FM band in the U.S.
Circle Surround technology allows FM radio stations nationwide to deliver digital quality surround sound content to millions of listeners through their home theater systems or car audio entertainment units. More than 300 radio stations in over 100 U.S. markets across 38 states reaching 67 percent of the population have already licensed HD Radio technology.
Implementation of the Circle Surround encoding solution for the HD Radio platform allows radio stations to encode any multichannel content into two-channel output for broadcast over the HD Radio system, which can then be decoded into full-bandwidth surround sound with any decoder found in millions of home theater and automotive systems. Up to a full 6.1-channel surround sound experience can be realized with a CS II decoder, which can be found in a wide variety of home theater products from Kenwood, Marantz, Accuphase and Theta Digital. For those listening to HD Radio receivers in their cars, Circle Surround Automotive technology also includes the latest CS decoder along with several specifically designed technologies that overcome the challenges of speaker placement and other obstacles specific to the automotive environment to deliver the best available surround sound in cars.
