Miranda Technologies has been awarded a patent for a new process to reduce audio delay on its range of NVISION 8500 series hybrid routers. The company, part of the Belden group, claims this "significantly reduces" latency on the disembedder, TDM crosspoint and embedder used in the systems. The technology, registered as US Patent 8359417, was invented by the NVISION routers team based at Miranda's Grass Valley facility in California, where the routers are designed and manufactured. The patented technique is said to "vastly reduce" delay that is inherent in "most" audio disembedders and re-embedders. In typical circumstances the NVISION routers is specified to reduce both disembedder and embedder delay by 20 lines or 24 audio samples and TDM audio crosspoint latency by one or two audio samples. In the case of the embedder delay can be brought down to as little as three lines when working with video in the same format and up to three lines for mixed formats, for example 625i/50 and 720p/59.94. Commenting on the patent, Scott Murray (pictured), Miranda's senior vice president for core products, said, "Our Grass Valley team continues to set the standard for world class signal distribution technologies. This patent is further confirmation of our leadership position as the most respected brand in professional routing systems and reinforces our ongoing drive to develop innovative solutions for the broadcast industry." www.miranda.com
