Columbia, MD and Warren, NJ - Nov 29, 2001 - IBiquity Digital Corporation, the sole developer and licenser of digital AM and FM radio broadcast technology in the United States, announced that the National Radio Systems Committee (NRSC) today completed its evaluation of iBiquity's IBOC (In-Band, On-Channel) FM technology and recommended that the FCC authorize the technology as an enhancement to the current analog FM broadcasting system in the US. The committee, which is jointly sponsored by the National Association of Broadcasters (NAB) and the Consumer Electronics Association (CEA), wrote that the FCC by approving the system would be "charting the course for an efficient transition to digital broadcasting with minimal impact on existing analog FM operation and no new spectrum requirements."

The NRSC's recommendation to the FCC is the result of a comprehensive test program devised and executed by the committee to determine the viability of iBiquity's FM IBOC technology and its ability to smoothly transition today's analog radio to digital. The test program included field tests of the system conducted at eight different FM radio stations across the country, in addition to laboratory tests and subjective sound quality evaluations by 480 listeners who evaluated thousands of audio samples recorded during the field tests. Specifically, in its report, the NRSC stated that the iBiquity FM IBOC (In-Band, On-Channel) system provides "greatly reduced impact of multipath interference (for mobile, portable and fixed receivers alike); superior resistance to co-channel and adjacent channel interference; support for enhanced data services; improved audio quality." IBiquity plans to rollout its technology in the U.S. next year with the launch of IBOC transmission equipment at the National Association of Broadcasters Conference in April 2002.

Milford Smith, the NRSC DAB subcommittee Chairperson, applauded the efforts of his fellow subcommittee members and those involved in the testing efforts. "The testing and evaluation of the FM IBOC system was extremely thorough. We reviewed data to determine the improvement in audio quality and reception, as well as the impact on today's analog FM and our evaluation confirmed the viability of the technology. IBiquity's FM IBOC technology has many advantages for broadcasters, manufacturers and consumers alike, and the transition will require relatively little inconvenience or expense. Radio will not remain the only analog medium in a digital world, and this system offers today's FM radio an excellent opportunity to smoothly transition to digital."

About the NRSC
The NRSC is jointly sponsored by the National Association of Broadcasters and the Consumer Electronics Association. Its purpose is to study and make recommendations for technical standards that relate to radio broadcasting and the reception of radio broadcast signals. The NRSC is a vehicle by which broadcasters and receiver manufacturers can work together towards solutions to common problems in radio broadcast systems. The DAB subcommittee, which was established to evaluate the IBOC DAB technology, includes participants from over 50 companies involved in the radio broadcasting and consumer electronics industries.
