AT&T announced the nationwide launch of AT&T Video Share service available in nearly 160 markets, allowing users to share live video over their wireless phones while on a voice call.

AT&T Video Share enables one-way live streaming-video feeds that can be seen by both parties while they are participating in a two-way voice conversation. Once the parties have initiated a Video Share call, either one can be the one generating the video stream for the other to see.

Video Share works exclusively over the AT&T 3G wireless network and is the first AT&T application to use the company's emerging Internet Protocol Multimedia Subsystem (IMS) platform. The new platform will be used to deliver a range of new Internet Protocol (IP)-based services and applications and will increasingly enable customers to access services and content over both wireless and wireline network connections.

Ultimately, services such as Video Share will be accessible over wireless devices, PCs and televisions. AT&T Labs researchers today are perfecting service enhancements that eventually will enable wireless video feeds to be shared over IPTV or PC screens.

To use the service, a Video Share-capable handset is required. Two Video Share service packages will be available for $4.99 a month for 25 minutes of Video Share usage or $9.99 a month for 60 minutes of usage. Users also may choose to pay as they go and pay 35 cents a minute each time they use the service. Video Share minutes are charged only to the sender.
