Opens the door for high performance head-end based interactive menus and games.
Slinger, WI (PRWEB) August 30, 2013
VideoPropulsion® Interactive Television (OTC "VPTV"), an industry leader in digital TV hardware and software technologies, today announced that it has been awarded US patent protection (#8514893) for technologies it has developed to reduce latencies in Quadrature Amplitude Modulation (QAM) devices used to send RF digital television signals over coaxial cables. Low latency QAM signaling is important for interactive television menuing, gaming, and other applications that send digital television signals over coax. The named patent holders are Matt Spransy, Senior Software Engineer, Joseph Nordman, Vice President of Engineering, and Carl Pick, Chairman & Chief Scientist.
"Digital television networks have inherent latencies as long as a second or more because of the necessity for pipelines in large data buffers to smooth the flow of streaming video data," said Nordman. "Those delays are disruptive to interactive television users who are, for instance, moving a cursor through a menu to select a program or service or playing a "twitch" game. Our technology exhibits latencies that are 80% lower than current commercial edge QAM modulators, gateways and appliances in the market today."
"Actual latency periods in VideoPropulsion FloodGate QAM appliances using the technology are typically well under ten milliseconds," reports Pick.
Spransy added, "We’ve found no degradation in video quality when streaming content is mixed with interactive applications using our protocol."
VideoPropulsion will include low latency interactive QAM features in it’s FloodGate family of products including FG-4800 Edge QAM and FG-5000 series bulk transcoders.
