Latency measures the time required for data to travel between two points on a network. It is particularly noticeable in live streaming, where delays can affect how quickly playback starts and how far behind real-time events appear.
Once a video stream has buffered enough data, moderate latency does not necessarily reduce picture quality. Packet loss, jitter, congestion, and insufficient bandwidth can be more directly responsible for interrupted playback.
A reliable connection with low packet loss and consistent performance on iptvgreat is generally preferable to one that has occasional extreme delays.
Technical takeaway: Latency matters, but it should be assessed alongside bandwidth, packet loss, and jitter.
