TeamSpirit Tablet Engine to Support iPad and Android Tablets, Available for Service Providers, Application Developers and Device Manufacturers

MOSCOW, Russia – November 17, 2011 – SPIRIT DSP, the world’s top voice and video over IP engines provider, today announced availability of TeamSpirit® Voice&Video Engine Tablet , for iOS and Android tablet devices. TeamSpirit Tablet turns any tablet computer into a high quality HD, multipoint videoconferencing endpoint. The software development kit (SDK) allows service providers, application developers and device manufacturers to quickly launch voice and video calling services for today’s hundreds of millions of tablet computer users.

TeamSpirit Tablet is a complete communications client-side voice and video engine, specifically adopted for tablets with 7 to 12 inch screen sizes, touch screen user interfaces and all available types of Internet connection support. TeamSpirit Tablet is designed to deliver high quality, hands-free audio using SPIRIT’s IP-MRTM (IP Multi Rate), wideband, scalable and error-resilient voice codec (IETF RFC 6262) and H.264 scalable HD video (up to 720p HD resolution) on the most popular iOS and Android-based tablet computers.

”Tablet computers are going to make a groundbreaking advancement in both the consumer and professional mobile videoconferencing business. Not only does it give a ”face to face” experience and real-life picture size, it also allows for multi-party business video meetings with remote teams and partners, as well as many other collaboration tools such as screen and document sharing, which makes no practical sense on smartphones. Tablets are quickly becoming the communication device of choice in the world, and we’re proud to say that our new TeamSpirit Tablet SDK is uniquely designed to support all popular tablet devices, conferencing scenarios and multipoint video layouts,” said SPIRIT’s Product Marketing Director Alexander Samarin.

TeamSpirit® Voice & Video Engine Tablet includes:

  • SPIRIT’s patent-free robust HD voice codec IP-MR™ (IETF RFC 6262) specially optimized for voice transmission over IP networks.
  • Cutting-edge speech enhancement module with SPIRIT’s proprietary AEC algorithms delivering the highest signal quality
  • Multi-layer packet loss recovery module for audio and video stream
  • Special module for network stream adaptation to network impairments, such as congestions, latency, varying delay (jitter), bandwidth limitations, etc.
  • Cross-platform videoconferencing scenario support and seamless integration with TeamSpirit® Conferencing Server, TeamSpirit® Engine PC, TeamSpirit® Engine Mobile, TeamSpirit® Engine Tablet
  • SPIRIT’s in-depth platform optimization saving tablet battery life
  • Specific platform features support: landscape/portrait mode, front/back camera selection

Samarin continued, “This release of TeamSpirit Tablet is also enhanced by Google’s patent-free VP8 video codec, in addition to standard H.263, H.264 AVC, MPEG4 video codecs – all supporting up to 30 fps (frames per second). It offers service providers, application developers and device manufacturers a high-level, plug-n-play rich API that is unprecedented in its ability to deliver the highest performing voice and video calling experience possible, and allows our customers to add great tablet screen capabilities to their mobile video communication services in record time.”
