Digital Fountain ships DF ToughStream Engine

Digital Fountain has begun shipping its DF ToughStream Engine for streaming applications, including IPTV and Internet TV.

ToughStream provides application and equipment vendors with an easy way to incorporate forward error correction (FEC) technology into streaming applications. ToughStream protects video and audio streams from common impairments, including packet loss, latency and jitter and lost packets typical of IP networks, and allows reliable, efficient delivery to the end-user without interruptions.

Employing Digital Fountain’s patented DF Raptor FEC technology, the ToughStream Engine minimizes bandwidth overhead and all but eliminates buffering delays by recovering lost packets without requiring retransmission. Any packetized stream can be protected, independent of the type of media encoding or compression, data rate, or use of encryption.
