How does Phenix define Real-Time vs. Low-Latency?
At Phenix we define "real-time" as less than 500 milliseconds 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.
|Use Case||Maximum Acceptable Latency|
|Two-way interactive experience||< 0.5 seconds|
|Micro-betting||< 0.5 seconds|
|Auctions||< 0.5 seconds|
|User-Generated Content (reviews, commentary)||< 3 seconds|
|Live-streaming||< 7 seconds|
|One-way broadcast||< 30 seconds|
