SPIRIT DSP Powers LG U+’s Popular U+070 Mobile Voice & Video Calling Application

South Korea’s Leading Telecommunications and Mobile Phone Operator Turns to SPIRIT as the Engine Provider to Enable the U+070 Mobile Application with HD-Quality Voice & Video Calling Across All Mobile Devices

BARCELONA, Spain (Mobile World Congress ’12) – February 29, 2012 – SPIRIT DSP, the world’s top voice and video over IP engines provider, has announced today that LG U+ (formerly known as LG Telecom) has turned to SPIRIT’s TeamSpirit® Voice&Video Engine Mobile as the engine to power HD-quality VVoIP (Voice&Video Over IP) calling on the company’s popular U+070 Mobile application service. LG U+ is the third largest carriers in South Korea, pioneering many innovative VAS services and serving 9.5 million subscribers.

Driven by a surge in smartphone penetration and a growing breadth of mobile video calling services by major industry players, mobile VVoIP usage is exploding, causing a greater number of service providers to introduce new mobile VVoIP services with rich features and differentiating their service with call quality. According to a new Juniper Research report, the number of mobile video calling users is projected to exceed 130 million by 2016.

LG U+’s U+070 Mobile application was launched at the end of 2011 and is currently available on Android mobile devices, and will soon be available on Apple’s operating systems iOS (5) and other smartphones and tablets. Powered by SPIRIT’s TeamSpirit Voice&Video Engine Mobile, U+070 Mobile users can conduct mobile VVoIP calling with a crystal-clear HD-quality experience.

“We have always been impressed with SPIRIT’s engine technology, so it was a natural move for us to turn to SPIRIT again to enable the highest quality calling experience possible on our U+070 Mobile application,” said LG U+’s Samuel Hwang,General Manager. “The Over-The-Top approach we use for video telephony allows our customers to select the most efficient way for routing traffic, using our own network, a WiFi connection or a broadband IP connection of any other operator. SPIRIT’s capabilities for ensuring quality, cross-platform calling has far exceeded other engine technologies, so we now plan to use SPIRIT’s engines to support  all our mobile VVoIP applications.”

Samuel Hwang continued, “SPIRIT DSP and LG U+ share a mutual vision to deliver the world’s best and most advanced experience in telecommunications across all IP devices and networks, and the U+070 represents our companies’ combined efforts to deliver on this promise of quality IP communications, anytime, anywhere.”

SPIRIT’s engine technology can also be found in many other Korean VVoIP services and VVoIP-enabled devices produced by local OEMs. With the launch of LG U+’s U+070 Mobile service, the Korean market has again validated its breakthrough positions in IP communications.

“LG U+ is a long-standing SPIRIT customer who has come to rely on our proven and highly optimized, mobile engine technology to handle voice and video processing and mitigate standard mobile VVoIP call quality issues, including Android device tuning, cancelling acoustic echo, network delays, jitter, lip synchronization and packet loss,” said SPIRIT’s Chairman Andrew Sviridenko. “The core approach of differentiation in technology innovative has always made LG U+ an extremely strong player in the telecom market. With the capabilities and cutting-edge features of the U+070 Mobile, L G U+ becomes even more competitive, allowing them to retain and gain new customers from traditional and new competitors. We’re pleased to be playing a key role by enabling a superior quality mobile VVoIP calling experience on the U+070 Mobile, which is quickly becoming an extremely popular LG U+ service.”
