Cingular plans to demonstrate a new, live-video sharing capability for use over wireless networks at the Consumer Electronics Show in Las Vegas next week.

The video service is expected to be launched later this year.

Cingular will enable customers to send live video in conjunction with voice calls with the press of a button. Users can switch the direction of the video stream during the call.

According to Cingular, the video service will be the first of its kind offered by a U.S. carrier.

"In the case of this technology demonstration, seeing is believing," said Kris Rinne, senior vice president of architecture and planning for AT&T, which is the sole owner of Cingular. "Consumers can get a real feel for what 3G wireless can do and what to expect in the future."

Alcatel/Lucent and LG Electronics are participating in the demonstration.

The video service is designed to operate over Cingular’s 3G UMTS/HSDPA (Universal Mobile Telephone System/High Speed Downlink Packet Access) network and recently deployed IMS (Internet Protocol Multimedia Subsystem) platform.
