"(...) Hewlett-Packard, Nokia and Infinity Broadcasting this week announced a plan to introduce what they call Visual Radio. The technology would combine the traditional over-the-air FM broadcast -- through a receiver included in the phone -- with text and graphics displayed on the phone’s screen.
Those text-and-graphics images could be coordinated with the broadcast -- to display the title of a song and the name of the artist, for example -- or provide information such as concert schedules, allow the user to buy ring tones from the artist or participate in radio station contests.
If some of those features sound familiar, there’s a reason -- display of artist and song title is available, for example, through satellite radio services. Traditional broadcasters are trying to fight back with new technologies, such as digital broadcasting, which allows them to transmit multiple channels and display information (song and artist, weather and traffic information and sports scores) to receivers equipped to receive them."
