What does Transmission Control Protocol mean?
Transmission Control Protocol, or TCP, provides an ordered reliable byte stream between endpoints. It includes mechanisms for handling lost data and controlling transmission. Reliable delivery does not mean every recovered byte arrives before a video player's playback deadline.
Why it matters
Retransmission takes time, and the player relies on buffered media to tolerate some interruptions. A sustained shortfall can still cause pauses. The visible symptom alone cannot identify TCP recovery as the cause; source and decoding problems can look similar. Compare the same media over a sound local connection and keep advanced packet captures private because they may expose account data.
A practical example
A short disruption can be recovered without a visible pause when enough media is buffered. The same interruption can affect a session with very little cushion near the live edge.
