Sangoma Voice Transcoding Card Officially Launched, Currently in Customer Trials

Today is a day for transcoding—Sangoma just officially announced its new D100 Card. The D100 supports up to 480 Channels of Premium-Quality Voice Transcoding per card and is designed to create efficiency, cost Savings and top audio quality in open source telephony applications. Octasic also announced a similar card this afternoon, marketed toward larger systems. “Voice transcoding is an essential, but costly, component of most VoIP applications and networks,” said Frederic Dickey, director of product management at Sangoma. “While software solutions can reasonably handle a handful of channels on a server, our card-based solution allows for hundreds of simultaneous voice transcoding channels in a single server, without compromising on audio quality.” Most IP telephony applications require the use of multiple types of voice codecs, which are used to digitally compress the voice signals at any given deployment. While voice signals from the Public Switched Telephony Network (PSTN) always come in the form of the G.711 codec, the VoIP terminal equipment and networks support a variety of voice codecs including G.729, G.726, AMR, etc. VoIP infrastructure most often needs to include the capability to mediate between endpoints supporting different codecs, but this ‘transcoding’ digital signal processing task is often costly, resource intensive and can affect the quality of the voice signals if it introduces too much latency or delay. The D100 card, available in PCI and PCI Express form factors,...

Octasic TXP1000 High-Density Video Transcoding Cards Announced

Today, Octasic announced the immediate availability of its new range of high density video transcoding cards, the TXP1000. Octasic has designed the TXP1000 PCI Express (PCIe) plug-in cards to directly offload the host CPUs for high channel density video and voice transcoding applications. The TXP1000 cards use Octasic’s award winning Vocallo MGW (DSPs) Digital Signal Processors and media processing software stack to provide an easy to use and low power (less than 25 Watts) accelerator card in a PCI Express form factor. The company claims that the TXP1000 cards provide the highest transcoding density per watt in the industry using: H.264, MPEG4, H.263 video codecs and G711, G729, AMR voice codecs: A single TXP1000 card easily delivers 335 channels of video transcoding while offering power consumption well within the power budget of a single PCI card. The TXP1000 cards should enable network service providers and Internet equipment manufacturers to rapidly develop and deploy efficient and high channel density video transcoding systems. John Fry, director of business development at Octasic Inc. said in today’s press release, “Compared to standard x86 server-based solutions that suffer from serious power, cost and scalability limitations, Octasic’s TXP1000-based systems provide tangible benefits that can cut video transcoding systems capital costs in half, reduce the power consumption by a factor of 8 and still deliver 5 times more channels per unit of rack space. Octasic is...
