How much internet speed does one HD IPTV stream really need?

Archived editorial answer

Allow headroom above the stream bitrate and test consistency, not only the highest speed-test result.

A practical check

Read the delivered bitrate on your actual device if available. Two simultaneous 5 Mbps streams require more than 10 Mbps of sustained throughput after accounting for overhead and other traffic. Use the affected viewing hour as the test window.
