Qualcomm licensing forward-error correction

Qualcomm said it is now licensing a forward-error correction (FEC) technology, a key element in assuring quality in the delivery of video and other content over the Internet to set-top boxes, mobile handsets, PCs and other devices.

Qualcomm acquired the technology, based on fountain codes, when it bought Digital Fountain last year.

"RaptorQ's FEC technology eliminates packet loss and can be integrated at the service application layer to improve performance across all types of content delivery services, networks and devices," said Michael Luby, vice president of technology at Qualcomm. "Content providers want to give customers a high quality of service across all their platforms. RaptorQ is designed to ensure that content arrives at its destination reliably, saving operators on network and customer service costs."

RaptorQ encodes content at the source. The encoded content is delivered over a network to targeted devices, where Raptor is used to decode the original content. The RaptorQ encoder and decoder libraries allow streaming and file delivery services to recover data lost in transit and completely reconstruct it, without using a backchannel, the company said.

RaptorQ technology protects against packet loss with memory efficiency enhancements, enabling it to run on small devices like handsets and simple set-top boxes and client platforms. The technology is network and operating system agnostic, making it flexible for all types of services, and as an application layer FEC, it is low-cost to deploy, Qualcomm said.

Operators and consumers benefit from RaptorQ-protected video streaming applications, whether they are deployed for IPTV, mobile TV, broadcast, video-on-demand, Internet video streaming or HD audio, according to Qualcomm.

Providers of IPTV services can use RaptorQ to extend the DSL loop – even over Wi-Fi – to reach more subscribers and improve quality of service with efficient, reliable video delivery – with no video or audio degradation – fast channel change times and low bandwidth overhead.

Enterprises can broadcast time-sensitive database updates to remote sites with fast, reliable operations and enhanced, error-free delivery of digital media – even in the most challenging network conditions.
