KDDI Deploys Digital Fountain's DF Raptor Technology

KDDI has deployed Digital Fountain's DF Raptor technology to deliver its new independent broadcast network for the company's "au"-branded mobile phones. The DF Raptor software is now deployed in all new KDDI "au"-branded handsets that support the "EZChannel Plus" and "EZNews Flash" services.

DF Raptor is an erasure correction code that mathematically recovers missing or lost data without requiring retransmission from the sender. DF Raptor increases file transmission efficiency even in extreme network conditions, enabling the delivery of more content over a broader geographic range while consuming less bandwidth.

  • Digital Fountain's patented DF Raptor technology has been made part of the global standard to support content delivery services over DVB-H (Digital Video Broadcasting-Handheld) wireless networks.

  • The adoption of DF Raptor technology for DVB-H follows its standardization in 2005 as part of the 3GPP (3rd Generation Partnership Project) MBMS (Multimedia Broadcast/Multicast Service) specification for GSM-based 3G cellular networks. Because the DF Raptor FEC provides exceptional packet loss protection but can be readily supported by general-purpose processors, the technology is ideally suited for the delivery of multimedia content to mobile wireless devices.
