Hoping to capitalize on the continued popularity of online music, Vivendi Universal Net USA has partnered with Internet technology developer CenterSpan Communications to launch an online service this year that securely distribs music and other entertainment to Internet users.

Details of the deal are vague, but the new service will bow sometime in the fall on one of Viv U Net USA’s operated Web businesses, including MP3.com, Emusic.com, MP4.com, RollingStone.com and GetMusic.com, as well as online gaming ventures Uproar and Flipside. RollingStone.com and MP3.com are said to be the front-runners to launch the new offering.

Financial terms of the pact were not disclosed, but Viv U Net USA will use CenterSpan’s C-StarOne content delivery network to create and launch the service. Last week, Sony said it would use C-StarOne to promote the music of five of its music acts.

The C-StarOne technology handles content aggregation, hosting, digital rights management, license clearing and network reporting. It is also the backbone of the Scour.com file-sharing service, recently relaunched by parent CenterSpan.

Deal is a coup for CenterSpan, which is looking to land the major record labels as clients — especially at a time when the music biz is looking for a viable way to build a business around the distribution of digital music files across the Web.

“We look forward to working with CenterSpan to launch an innovative entertainment service that offers premier content to millions of online fans,” said Steve Sheiner, chief revenue officer of Viv U Net USA.

Based in Los Angeles, Viv U Net USA was founded last year to provide technology, site development, online distribution and content for Vivendi’s Web sites. The division also oversees the development of a service called Moviso, which sells mobile phone perks such as ring tones and celebrity voicemails.
