News January 7, 06:46 Eastern Time LAS VEGAS (Jan. 7) BUSINESS WIRE -Jan. 7, 1999--Lucent Digital Radio, a venture of Lucent Technologies, today announced it is licensing its Perceptual Audio Coder (PAC) technology to Audio Video Communications (AVC), a supplier of radio broadcasting equipment in Australia. Audio Visual Communications (www.avcom.com.au) will use the technology in its newest broadcasting products, including its TieLine bi-directional audio codec, which allows high quality remote broadcasting over phone lines. TieLine is intended for applications such as remote broadcast links to the production studio, studio-to-studio program links, and news gathering to live-to-air reporting. When completed, TieLine is expected to enable up to 15 kHz of broadcast quality digital sound to be sent over a 3 kHz telephone line in real time, anywhere in the world. It may also be used for the audio portion of a remote TV broadcast. "We are pleased to extend our Bell Labs-developed PAC technology to a wider customer base," said Suren Pai, president of Lucent Digital Radio. "PAC will help make digital broadcasting possible, and Lucent wants to provide the largest possible community of developers with an essential building block for this emerging industry." Lucent Digital Radio uses PAC in its In-Band On Channel (IBOC) DAB system, which will allow radio broadcasters to transmit higher quality sound over AM and FM, and support the introduction of innovative, low-cost data broadcast services. The PAC encoder converts analog audio signals into a digital signal, then compresses the data by at least 15 to one, so that music, for example, can be represented accurately with only about one-fifteenth the number of bits per second as are used on a compact disc. The PAC encoder enables new capabilities, such as CD-like audio quality at bit rates lower than 96 kilobits per second (Kbps). LDR will begin testing its systems over conventional FM stations in the first quarter of 1999, and over AM stations in the second half of the year. Other product developers interested in working with Lucent Digital Radio on PAC licensing may contact William Casey, Director, Marketing & Sales at 908-580-7008 or williamcasey@lucent.com. Lucent Technologies and its research and development unit, Bell Laboratories, have been leaders in the digital encoding of information used in communications systems, and have been at the forefront of digital audio broadcasting (DAB) technology for the past decade. DAB systems are expected to be commercially available starting in 2000. This migration to digital radio presents a sizable opportunity for the consumer electronics industry and will enable radio broadcasters to provide improved services to listeners. Lucent Digital Radio is the second Lucent venture in the digital broadcast market. Lucent Digital Video, announced in January, 1998, markets its industry-leading MPEG-2 encoders to the broadcast, cable, wireless cable, fiber optic and satellite markets.
