Infinity launches multicast station in Chicago (Thu May 12, 2005 1:50 PM ET)
LOS ANGELES, (Reuters) - Hoping to lure more listeners to traditional radio amid growing competition from satellite radio and iPods, Infinity Broadcasting on Thursday said it was dividing the frequency of a Chicago radio station into two to air a new station targeting a younger audience.
By splitting the radio frequencies into high-definition niches, Infinity, a unit of Viacom Inc., is embracing a technology known as multicasting.
Infinity said its popular Chicago country station, WUSN-FM, was granted experimental authorization from the Federal Communications Commission to broadcast the supplemental audio service.
WUSN-FM began broadcasting digitally in June 2003.
The multicast station, WUSN-FM 99.5 HD-2, will be programed independently, featuring a playlist of new music from established country artists as well as music from up-and-coming stars.
Infinity said its digital broadcast will offer text displays of song, title and artist information on HD Radio-compatible receivers.
HD Radio technology transmits digital audio and data alongside existing AM and FM analog signals and provides CD-quality sound and scrolling text displayed on a radio screen.
Infinity said WUSN-FM 99.5 HD-2 will be the first continuously programed HD Radio multicast channel by a commercial broadcaster.
Infinity has converted various stations to high-definition, including stations in New York, Los Angeles, Chicago, San Francisco, Dallas, Philadelphia, Washington, D.C., Boston, Detroit, Seattle, Cleveland, Las Vegas, and Fresno.
