The configuration of received chunks is the key to the video playback quality. The lack of more important chunks could degrade playback quality significantly. Unfortunately, directly applying rate-distortion (RD)-first or importancefirst scheduling strategy in data-driven P2P streaming could incur serious content bottleneck problem. In this work, we first identify this new content bottleneck problem and propose a simple strategy-switching approach to soften the unique phenomenon so as to further improve playback quality.
