How does Phenix define Real-Time vs. Low-Latency?

At Phenix we define “real-time” as < 1/2 second from photons into the camera at one end of the system to photons out the screen on the other end (sometimes referred to as “glass-to-glass” time). We consider anything under 5 seconds to be “low-latency.”

There are some interactions that are possible in real-time that are not possible in “near real-time” or higher latencies. These include micro-betting, talking/chat, gamification of sports, and auctions, to name a few.

The following table gives some examples of usage vs. latency.
