Latency can vary from tens of milli-seconds to several seconds.
ZiXi protocol can start benefit from one provide benefit with a delay of a single frame (30ms), while increasing the latency will provide more robustness for the error-recovery.
In low latency (below 1500ms) the error recovery is based on a hybrid approach of FEC and ARQ. FEC will add overhead of up to 30% (adaptive–without congesting the network) .
...
Latency can be set to any value, we can propose recommend two common modes:
- Interactive mode - 500ms
- Non-interactive mode – 4000ms
Latency below 1500ms will add an FEC overhead of up to 30%.
