Digital Fountain Announces First IETF-Compliant Reliable Multicast & Broadcast Libraries.Business Editors/High-Tech Writers FREMONT, Calif.--(BUSINESS WIRE)--June 7, 2004 DFBroadcast 2.0 Available Immediately to Provide Faster Reception, Shorter Broadcasts Across Broad Range of Network Conditions Digital Fountain, a supplier of network transport software, today announced DFBroadcast 2.0, the first commercially available Internet Engineering Task Force (c/o Corporation for National Research Initiatives (CNRI), Reston, VA, www.ietf.org) Founded in 1986, the IETF is a non-membership, open, voluntary standards organization dedicated to identifying problems and opportunities in IP data networks and proposing technical solutions to the (IETF See Internet Engineering Task Force. IETF - Internet Engineering Task Force ) -compliant Reliable Multicast library. DFBroadcast 2.0 complies with the forthcoming FLUTE (File Delivery over Unidirectional The transfer or transmission of data in a channel in one direction only. Transport) standard to be published shortly by the IETF. DFBroadcast 2.0 is applicable to both wireless broadcast and wired multicast applications deployed by commercial services and enterprise developers. Utilizing Digital Fountain's patented Meta-Content technology, DFBroadcast 2.0 allows for shorter broadcasts, faster reception and less compute-intensive reception than any other technology across an extremely broad range of network conditions. "DFBroadcast 2.0 accelerates the adoption of Digital Fountain technology in the data broadcast and enterprise multicast market," said Charlie Oppenheimer, President and CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. of Digital Fountain. "With Honda and XM recently endorsing our technology for these kinds of new applications and now having a standards compliant implementation, we are well on our way to taking a leadership position in this market," added Oppenheimer. The FLUTE Standard Developed over several years by the Reliable Multicast Transport (RMT RMT right mentotransverse (position of the fetus). RMT 1. Registered Massage Therapist 2. Renal mesenchymal tumor ) working group of the IETF, that included researchers from Digital Fountain, Cisco, Nokia, Microsoft and others, the FLUTE standard aims to overcome the challenges of broadcast and multicast applications transmitting data to a large population of receivers (or clients) concurrently. FLUTE is a suite of building blocks that combine to form an overall reliable multicast/broadcast transport solution. The building blocks define packet formats, multi-rate layered data streams, payload identifiers, FEC See forward error correction. FEC - Forward Error Correction (Forward Error Correction A communications technique that can correct bad data on the receiving end. Before transmission, the data are processed through an algorithm that adds extra bits for error correction. If the transmitted message is received in error, the correction bits are used to repair it. ) identifiers and congestion control
Congestion control concerns controlling traffic entry into a telecommunications network, so as to avoid congestive collapse by attempting to avoid . Implementers can choose among the blocks and combine different standards-compliant implementations from different sources. Since these applications are primarily one-way in nature (meaning receivers do not ordinarily communicate back to the sender), the FEC technology provides the essential ingredient to achieve reliability. "DFBroadcast 2.0 showcases the power and potential of the forthcoming FLUTE standard," said Dr. Michael Luby Michael George Luby is a mathematician and computer scientist, co-founder and Chief Technology Officer of Digital Fountain. In coding theory he is known for leading the invention of the Tornado codes and the invention of the LT codes. , Chief Technology Officer of Digital Fountain and a leading member and author in the IETF RMT working group. "After so much effort, research and optimization, by so many talented people, it will be a delight to see this technology being deployed and used." DFBroadcast 2.0 Digital Fountain's DFBroadcast 2.0 provides a complete FLUTE-compliant network transport solution that can be integrated into any application or platform. DFBroadcast 2.0 provides several important capabilities: Permits Unscheduled and Intermittent Reception With Digital Fountain's Meta-Content technology, receivers need only collect any set of packets approximately equal in length to the original source data to instantly and perfectly recreate the data. Because there is no need to worry about which packets any particular receiver collects, the data is received quickly and reassembled accurately, even amidst intermittent reception schedules and frequent broadcast interruptions. In addition, because each Meta-content packet is unique, any broadcast or multicast session can continue for as long as necessary, without risk of receivers starting to receive duplicates. Low FEC Overhead Unlike other Forward Error Correction (FEC) schemes, there is no difference in computational efficiency of the algorithm with larger amounts of loss, there is no need to pre-determine a maximum packet loss provision and there is also no need to carousel (repeat) sending the same data. No Limit on Size of Files Traditional FEC algorithms work well on small-sized data but get computationally expensive A computationally expensive algorithm is one that, for a given input size, requires a relatively large number of steps to complete; in other words, one with high computational complexity. as the size of the objects to be broadcast grow larger. With Meta-Content technology, performance is linear, regardless of the size of the objects. Automatic Configuration for Small Memory Receivers One challenge when multicasting or broadcasting large files is that these files are often larger than the amount of RAM available on the receiver or client. DFBroadcast determines an optimal segmenting scheme for the RAM footprint of the receiving clients, and automatically breaks large files down into smaller sizes and interleaves Meta-Content for each segment throughout the broadcast/multicast. Mix and Match Platforms Any combination of sending and receiving platforms can be employed, and all are mutually compatible for sending and receiving. Multiple Uncoordinated un·co·or·di·nat·ed adj. 1. Lacking physical or mental coordination. 2. Lacking planning, method, or organization. un Senders Because Meta-Content packets are generated at random, it is possible to use multiple senders and allow the receiver to collect any random collection of packets from the different senders without coordinating which packets each sender transmits. This allows for high-availability redundant configurations with the added benefit that receivers can receive at an aggregate rate equal to the sum of the rates of the senders. Another benefit of the multi-sender property for cellular-style broadcast architectures is that there is never a need to coordinate hand-offs between transmitting cells. Instead, every cell can generate a unique set of Meta-Content and the receiver can aggregate any collection received from the different cells. Licensing DFBroadcast 2.0 is available immediately. Libraries are available now or will be available shortly for Windows, Solaris, Linux, VxWorks, Symbian, BREW, WindowsCE and for processors including x86 compatible Refers to a computer system that is compatible with Intel's x86 CPU family. All operating systems and applications that run on Intel x86 systems (Core and Pentium CPUs) run exactly the same on an x86-compatible computer.

For example, .5 MIPS is 500,000 instructions per second; 100 MIPS is a hundred million instructions per second. , ARM, Hitachi and others as demanded. Digital Fountain offers three types of licenses. A Development License, required to begin development, is priced starting at $25,000, with one year of consulting and support. Additional license models include an OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and license (for manufacturers, service providers and software developers) and a Deployment License.
