public class LatencyMeasurement
extends Object

A latency measurement consists of the measured latency and the uncertainty of the measurement. Use BroadcastPlayer.getEndToEndLatency() to get a measurement. The measured latency is at most +/- uncertainty milliseconds from the actual latency.

For example if the measured latency is 500 ms and the uncertainty is 100 ms, the actual latency is between 400 and 600 ms.

To avoid confusion, avoid showing the latency to end users if the uncertainty is relatively large. In extreme cases on unreliable mobile networks, the uncertainty may be very large. For example if the uncertainty is 2000 ms and we know the actual latency is 1500 ms, the latency can in theory show as -500 to 3500 ms. In practice, the measured value is likely close to the actual latency.
