More About Modeo's New York Beta Service

Modeo will stage its New York City beta activities in phases throughout the first quarter of 2007. Activities include the initiation of a formal beta test group that is scheduled to commence in late January. To further showcase the DVB-H mobile TV opportunity, Modeo is offering service to a select group of wireless carriers, reporters, industry analysts, financial analysts, and content providers. Modeo anticipates several hundred users will participate during the course of Modeo beta service.

Modeo is working with several key partners as part of this milestone event for the emerging mobile TV sector. Centercode Inc. is managing Modeo's formal beta test group activities. GCR Custom Research LLC (formerly Gartner Custom Research) is providing consumer use and service analysis. M:Metrics is providing Modeo the capability to capture actual user log data through the sophisticated measurement methodology of M:Meter. Building on Modeo's previous trialing activities, participants in Modeo's New York beta service will provide valuable feedback on a variety of parameters, including programming content, coverage quality, ease of use of the Modeo Mobile TV Smartphone device and overall use case scenarios. Modeo expects to use this feedback to evaluate network distribution options with wireless carriers.

"Modeo is pleased to have this opportunity to showcase our progress toward delivering on the promise of mobile TV," commented Michael Ramke, Modeo's recently appointed president and former vice president of marketing and business development. "By moving beyond technical trial efforts and into true commercial grade network service, we continue to position Modeo as an integral

player in the dynamic mobile TV space. Participants in our New York beta service will have a front row seat in the evolution of mobile TV."

Modeo is a DVB-H (Digital Video Broadcast-Handheld) pioneer: In 2003 Modeo secured, through an affiliate, unencumbered spectrum rights through a Federal Communications Commission auction and began conducting technical and consumer trials of its mobile TV service in Pittsburgh in 2004.

"The Modeo DVB-H Smartphone is a pioneering advancement in the world of mobile communications and entertainment," said Todd Achilles, vice president of sales and marketing for HTC America. "HTC is extremely pleased to be working with Modeo on this significant milestone in the evolution of wireless entertainment."
