ROSH HA'AYIN, ISRAEL - DVB-ASI has been established as the robust Transport-Stream interface of choice for many years but now video over IP is becoming the new standard for video delivery. Replacing existing equipment with ASI interfaces is expensive hence VideoFlow is incorporating an ASI interface into its products using DekTec's DTA-2144 quad ASI interface card.
NyeTec, the UK distributor for both VideoFlow and DekTec, will showcase the VideoFlow equipment with the DekTec ASI card inside at the NyeTec stand C31 in Hall 2.
"Being the distributor for both companies gives us a unique insight into the strengths of both VideoFlow and DekTec and the realisation that bringing them together creates a solution that meets our customers business needs, i.e. how to benefit fully from the new Internet-based method of video delivery while protecting their existing equipment investment," says Terry Nye, Director of NyeTec.
Nilesh Mandalia, VP of Sales at DekTec, explains, "The move to using the Internet for video connections is rapidly taking off as it significantly reduces costs. VideoFlow's Digital Video Protection (DVP) ensures that no packets are lost and jitter is eliminated so that customers can now rely on this new way to have a robust connection. And, now that VideoFlow is incorporating our ASI adapter cards, professional broadcasters can continue to use their existing equipment so the costs of moving to video over IP are minimal and the on-going saving considerable."
Larry Leibson, VideoFlow's VP of Sales, adds, "We chose DekTec's cards as they are a standard format - a PCI Express card - so they simply plug straight into our DVP without us having to do any modifications. We examined other offerings in the market and selected DekTec. Their design is excellent as is the reliability with thousands already in use making it the de facto standard. This will significantly expand our potential market as we now offer a very easy and cost effective path for customers using legacy broadcast equipment to lower the cost of video delivery."
VideoFlow technology
Live video broadcast are sent as a continuous bit stream, which the Internet was never designed to handle, resulting in artefacts caused by jitter and packet loss. More than a couple of seconds of latency is unacceptable by customers expecting to enjoy the excitement of live events like sport as they happen. VideoFlow's patent pending technology opens the Internet for delivering content by ensuring that no packet is lost and nullifying the jitter caused by transiting the Internet. By doing so, it affords broadcasters, teleports and operators the opportunity to use a highly advanced, low cost solution for live, high quality video streams in place of existing, expensive solutions.
The DVP comes as a "Plug and Play" pair - a Protector, which transmits the packets and stores them until it is certain that they have been correctly received, and a Sentinel which monitors the health of the video stream by watching for packet loss and requests packets to be resent from the Protector's cache only if required. This is ensured by VideoFlow's patents, which cover techniques to minimize the number of packets that have to be resent. VideoFlow's solution is highly flexible working with internet connections as slow as 200Kbps or as fast as 800Mbps yet delivering the desired high quality. VideoFlow's patents also cover techniques to reduce bandwidth overhead to the minimum possible and to keep any delays at less than two seconds, which is the maximum tolerated for true live broadcasts. VideoFlow's DVP family of products enables the reduction of bandwidth requirements, cutting operational costs compared to the current solutions.
Reducing operating costs is a major driving force. VideoFlow technology enables customers to transport real time, high quality video over unmanaged, best effort networks that frees customers from the need and costs of having an expensive Service Level Agreement (SLA). In addition, VideoFlow's capability of dynamically adapting for optimal video quality is becoming an asset for building a cost effective, professional, live video contribution and distribution flow.
