Digital Fountain's FEC Standardized by 3GPP

Digital Fountain's forward error correction (FEC) technology has been standardized by 3GPP, the 3rd Generation Partnership Project, as a mandatory component of the Multimedia Broadcast/Multicast Service (MBMS) for 3rd generation (3G) cellular networks. Digital Fountain's "DF Raptor" technology will be used as part of the MBMS standard for both streaming and file download services.

Digital Fountain's DF Raptor is an advanced and highly flexible FEC technology that ensures the efficient and error-free delivery of both multimedia streams and data files even in the presence of a wide range of network impairments. MBMS employs multicast and broadcast transmission for bandwidth-hungry multimedia services so that many mobile devices can efficiently share common radio and network resources.

Digital Fountain said that by protecting MBMS signals from packet loss, its technology enhances the overall user experience and assures the service provider that multimedia content will be delivered in its entirety without degradation. It noted that its FEC implementation was selected over competitors because it makes optimal use of transmission bandwidth and imposes a minimal processing burden on the receiving devices in order to protect against a wide range of packet loss.
