Enabling Interactive Applications over QAM

VideoPropulsion® (OTC: VPTV), an industry leader in digital TV hardware and software technologies, today announced that it has applied for patent protection 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, television gaming, and other applications that send digital television signals over coax.

“Digital television networks have inherent latencies (delays) as long as a second or more because of the necessity for large data buffers to smooth the flow of video data,” said Joe Nordman, Vice President of Engineering for VideoPropulsion. “Those delays are disruptive to interactive television users who are, for instance, moving a cursor through a menu to select a program or service. Our technology exhibits latencies that are 80% lower than current commercial edge QAM modulators, gateways and appliances in the market today.”
