Buffer reserve trace
Reconstructed adaptive stream, c. 2012
Observed surface
00:00 playback begins with 8.0 seconds held
00:12 arrival falls below consumption / reserve 6.1 seconds
00:17 reserve 2.4 seconds / next segment incomplete
Implied procedure
00:20 reserve 0.0 / playback pauses
00:21 lower-rate variant requested at segment boundary
00:25 reserve 4.2 seconds / playback resumes
Interpretive residue
00:40 reserve stable / visible quality reduced
Continuity was restored by spending image detail instead of more waiting time.
