Lucent Digital Radio and Moseley Associates Announce Agreement to Test Digital Audio Broadcast System.WARREN, N.J.--(BUSINESS WIRE)--Aug. 23, 1999--
Lucent Digital Radio, a wholly-owned subsidiary of Lucent Technologies (NYSE NYSE
See: New York Stock Exchange : LU), and Moseley Associates, a leader in the design and manufacture of radio broadcast equipment, today announced that they have agreed to jointly test Studio Transmitter Link (STL (STereoLithography) A 3D printing file format created by 3D Systems for its stereolithography system. Also supported by many numerical control, rapid prototyping and rapid manufacturing machines, STL provides the surface geometry of the item in triangles. ) technology that will further develop Lucent Digital Radio's In-Band On-Channel In-band on-channel (IBOC) is a method of transmitting digital radio and analog radio broadcast signals simultaneously on the same frequency.
By utilizing additional digital subcarriers or sidebands, digital information is "piggybacked" on a normal AM or FM analog (IBOC See HD Radio. ) Digital Audio Broadcasting Digital radio. It is the digital successor to analog AM and FM radio. See HD Radio and DAB. (DAB) system. Tests will commence immediately and will be conducted at both Lucent Digital Radio and Moseley facilities.
The STL link, an integral part of the radio broadcast chain, connects a radio station's studio to its transmitter site. The Lucent Digital Radio IBOC system is designed as an end-to-end solution (jargon) end-to-end solution - (E2ES) A term that suggests that the supplier of an application program or system will provide all the hardware and/or software components and resouces to meet the customer's requirement and no other supplier need be involved.
Compare: turn-key solution. that will enable broadcast stations to seamlessly convert to an all-digital AM or FM broadcast scheme.
Lucent Digital Radio recently conducted tests of its IBOC FM system on National Public Radio (NPR NPR

The currency market, also known as the Foreign Exchange market, is the largest financial market in the world, with a daily average volume of over US $1 trillion. ) member station WBJB-FM. These tests were the first time that an IBOC system successfully passed a hybrid (both analog and digital) signal over a radio station's antenna and transmitter without affecting the host analog signal An analog or analogue signal is any time continuous signal where some time varying feature of the signal is a representation of some other time varying quantity. It differs from a digital signal in that small fluctuations in the signal are meaningful. .
"Working with Moseley, an acknowledged leader in the STL field, will further demonstrate to the radio industry that our IBOC system delivers sound results," said Suren Pai, president of Lucent Digital Radio. "Our end-to-end IBOC system is designed to ensure that radio broadcasters make a seamless transition from analog to an all-digital IBOC future."
"We believe that IBOC is a tremendous opportunity for all involved in the radio broadcast industry, and we look forward to helping Lucent Digital Radio develop the best possible IBOC system," said David Chancey, national sales manager of Moseley Associates. "Furthermore, our joint efforts will allow our Starlink STL customers to understand how our product works with 21st century radio technology."
Lucent Digital Radio's IBOC DAB system is an enhancement to current analog AM and FM radio broadcasting systems. It will provide greatly enhanced sound quality for AM radio, CD-like quality for FM radio, as well as interference-free reception and innovative new data services.
Lucent Digital Radio draws on several patented Bell Labs digital audio and channel coding techniques that provide robust digital signal delivery in an impaired broadcast channel, including Lucent's Perceptual Audio Coder Perceptual Audio Coder (PAC) is an algorithm, like MPEG's MP3 standard, used to compress digital audio by removing extraneous information not perceived by most people. (TM) (PAC(TM)) technology, which delivers CD-like quality audio at 96 Kilobits per second (unit) kilobits per second - (kbps, kb/s) A unit of data rate where 1 kb/s = 1000 bits per second. This contrasts with units of storage where 1 Kb = 1024 bits (note upper case K). ; Unequal Error Protection, which prioritizes information based on its impact to audio quality; and Multi-Streaming, which provides for a more robust signal in an impaired channel.
The IBOC approach will allow broadcasters to introduce digital audio programming to listeners on their current dial positions using existing transmitters and antennas. IBOC DAB is both backward- and forward-compatible: current AM/FM AM/FM Amplitude Modulation / Frequency Modulation
AM/FM Auto-Mapping/Facilities Management receivers will still be able to receive the existing analog signals in the new system. When a station elects to turn off the analog signal in the future, IBOC DAB-compatible receivers will operate with the remaining all-digital signal.
A Lucent Technologies venture, Lucent Digital Radio is developing IBOC DAB technology for AM and FM broadcasting worldwide. Lucent Digital Radio's IBOC system will be resistant to multipath and other forms of interference that impair current analog transmissions.
