Digital Fountain's Forward Error Correction Standardized for DVB-H

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 earlier this year 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.


Digital Fountain's DF Raptor technology is an advanced and highly flexible type of FEC that enables the efficient and error-free download of multimedia data files in the presence of a wide range of network impairments.


Digital Fountain said that by employing DF Raptor FEC as part of IP datacasting services over DVB-H to protect against packet loss, DVB-H service providers and end users can be assured that multimedia content will be delivered complete and error-free in a minimum amount of time across a wide coverage area.


Within DVB, DVB-H is an open industry standard for the delivery of mobile broadcast digital services to handheld devices. DVB-H has already generated significant industry activity, including technical and commercial trials, a range of product launches, and several planned network rollouts around the world.

  • In June 2005, 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.












MBMS
– The Newest Mobile Multimedia Standard
In
June of 2005, the 3rd Generation Partnership Project (3GPP) completed
Release 6 of its technical specifications for the continued evolution of
3rd generation (3G) cellular networks based on the GSM infrastructure.
Included in 3GPP Release 6 are the specifications for the Multimedia
Broadcast/Multicast Service (MBMS), an IP-based technology designed to
more efficiently deliver multimedia (video, audio, and text) content over
3G radio and network resources. Here is an overview.
