Qualcomm’s MediaFLO today revealed its first major content partner for its multicast TV service, announcing that Network Live, a joint venture between AOL, XM Satellite Radio and AEG, would supply streaming live concert feeds and performer interviews to the aspiring mobile TV network.

Qualcomm has kept most of its plans for MediaFLO under wraps as it prepares for its first market trials later this year, but the vendor is expected to reveal much more detail about the service at CTIA Wireless 2006 this year, showing live demos of the service as well as giving more insight into its content model. The MediaFLO network will work on a TV broadcast model, sending the same streaming content to potentially millions of Forward Link Only (FLO)-enabled handsets. Verizon Wireless announced last year that it would be the first carrier to adopt the service.

While MediaFLO has been expected to announce content partners to populate its line up of 50 or so TV channels, the Network Live announcement is surprising since the venture is hardly the traditional broadcast TV outlet expected to dominate mobile TV airwaves. Network Live launched last summer as an all-digital medium, distributing live and on-demand concert and event video and audio over the AOL online music portal and the XM satellite system. While the FLO network will certainly enable live streams to its end-customers, it won’t support on-demand video as the network doesn’t maintain an individual link to the handset.

Qualcomm plans a trial launch of MediaFLO by the end of the year, keeping it on pace with new rival Crown Castle, which also plans to launch a mobile TV service using rival technology digital video broadcast-handheld (DVB-H) under the name Modeo.
