- Sep 30, 2026 Why RTP Timestamps Do Not Count Seconds RTP timestamps advance at the codec clock rate, which makes arithmetic modular and stream-relative; the rules that follow for wrap, comparison, and cross-stream sync. internet protocols
- May 5, 2026 Early RTCP Feedback: Negative Acknowledgements, Picture Loss, and Transport Congestion How the feedback profiles let a receiver report loss in milliseconds instead of seconds, what each message type asks for, and the timing rules that keep them from flooding a session. internet protocols
- Apr 22, 2026 Mapping RTP Clocks to Wall Time for Cross-Stream Synchronization Sender reports tie an RTP timestamp to an NTP instant; using that correspondence to align audio and video exposes clock offset, drift, and the limits of the mapping. internet protocols
- Oct 24, 2025 Sizing and Adapting the Jitter Buffer How a playout buffer trades latency for concealment, the difference between a fixed and an adaptive delay target, and why the delay estimate must not follow every spike. internet protocols
- Apr 7, 2025 Fragmenting Encoded Frames to Fit the Path MTU Why a codec frame larger than a datagram needs RTP-level fragmentation, how the marker bit and timestamp stay shared, and what happens when one fragment is lost. internet protocols
- May 13, 2024 The RTP Fixed Header: Twelve Bytes That Carry a Media Stream What each field of the 12-byte RTP header means, why sequence numbers and timestamps are independent, and which failures the design accepts to stay small. internet protocols
