Forward error correction (FEC) technology IP developer Digital Fountain, Inc. has announced a major licensing deal with Nokia. This agreement will allow Nokia to incorporate Digital Fountain’s advanced FEC technology in future Nokia products. According to Digital Fountain, its latest generation of patented FEC technology, DF Raptor, supports the efficient delivery of data files or multimedia streams even in the presence of high packet loss. By comparison to other FEC technologies, DF Raptor minimizes processing requirements and the use of transmission bandwidth while providing essentially unlimited flexibility in loss protection. By enabling reliable delivery of content over a wide range of adverse network conditions, DF Raptor allows network operators to maximize service quality to their subscribers.

In fact, in June, DF Raptor technology was standardized by 3GPP, the 3rd Generation Partnership Project, as a mandatory component of the Multimedia Broadcast/Multicast Service (MBMS) for third-generation (3G) cellular networks. By adopting DF Raptor as part of the MBMS standard for both streaming and file download services, 3G service providers and end users are assured of both high quality delivery of audio and video services, and fast and reliable data transfer, said Alan Jacobson, Digital Fountain’s director of marketing.

Jacobson added that DF Raptor is an advanced and highly flexible FEC technology suitable for a wide range of applications and requirements. It offers a highly scalable media delivery solution ensuring the complete and error-free reception of content. In addition, it enables lightweight software-based solutions with low processing requirements for multimedia streaming and data transfer applications. It also offers flexible parameter and implementation choices to best suit actual levels of packet loss as seen by the end user. Other features include low overhead for bandwidth efficiency, high code efficiency in correcting lost packets, and equal protection to all end users irrespective of individual end-user packet loss patterns.

According to the developer, DF Raptor is part of the first release of the MBMS standards, enabling 3G wireless broadcast video and file transfer services. By protecting MBMS signals from packet loss, DF Raptor enhances the overall user experience and assures the service provider that multimedia content will be delivered in its entirety without glitches or defects.
