83ms wire-to-wire latency between encoder and LLD2 decoder

In the video world, the time lag between the instant a frame is captured and the instant that frame is displayed is called glass-to-glass latency. Research has shown that an operator’s ability to accurately perform precision manual tasks or surgical tasks decreases when glass-to-glass latency exceeds a 300 to 500 ms range. Euresys can now reduce the glass-to-glass latency to less than 100ms in full HD, in specific conditions with a dedicated decoder. Euresys has recently developed a low latency video encoder, designed for remote control of industrial processes in critical or hazardous areas. With the encoder, operators will be able to control machines, cranes or robots from afar with an improved response time, thanks to the advanced technologies implemented to stream full HD video over an IP network.
