First voice-to-video call at MWC


LG Electronics (LG) successfully demonstrated the world’s first voice-to-video conversion over a LTE network at the Mobile World Congress (MWC) 2012. The demonstration, based on LG’s proprietary technology, enables users to switch back and forth between high quality voice and high resolution video call modes during an ongoing telephone conversation.

Also demonstrated was a video sharing service, which enables real-time sharing of videos over a LTE network, as they are being recorded.

LG’s LTE voice-to-video conversion process adheres to the IP Multimedia Subsystem (IMS) Profile for Conversational Video Service, the industry standard established by the GSMA to govern the delivery of both video and voice data over LTE. LG will launch LTE-capable smartphones compliant with Conversational Video Service later this year.

“LG will continue to lead in LTE by developing and introducing innovations that consumers can actually experience and benefit from,” says Dr. Jong-seok Park, LG Electronics Mobile Communications Company President and CEO. “The LTE sector is advancing at light speed and our voice-to-video conversion technology is in the best position to be adopted industry-wide.”

At last year’s MWC, LG successfully demonstrated Voice over LTE (VoLTE) and video calls. Prior to the introduction of LTE technology, high definition video calls on smartphones were impossible with 3G networks unable to handle the volume of data at the speeds required for high quality video images.
