SPIRIT DSP, the voice and video over IP engines provider and LG U+, South Korean''s leading mobile and telecommunications service provider (formerly known as LG Telecom) have singed an agreement  to power HD-quality VoIP and video-calling on mobile devices. 

"SPIRIT DSP has a strong presence in Asia Pacific market and S. Korea.  LG U+ has come to rely on SPIRIT's proven and highly optimized, carrier-grade engine technology to handle voice and video over IP processing," said SPIRIT's VP Sales Alex Kravchenko.  "We're pleased to continue our cooperation with LG U+ and maintain our critical role in bringing South Korean mobile users the highest quality communications experience possible."

TeamSpirit Engine is an SDK for real-time IP calling/conferencing communications, allowing application developers and service providers to offer superior quality voice and video products to millions of global users.  TeamSpirit Engine software uniquely combines scalable echo- and noise-free audio with scalable video, a necessary marriage to ensure the highest quality conferencing experience.

TeamSpirit enables many hours of battery life in wideband talk mode. The voice engine includes highly optimized standard voice codecs and a patent-free wideband error-resilient scalable SPIRIT IP-MR voice codec (IETF RFC 6262).  The video engine includes SPIRIT's H.264 scalable video codec that is able to adapt streams to each peer’s network and PC environments without heavy transcoding and it includes a multi-component stream protection module that compensates for network jitter and packet loss.
