Conducting Rate-Distortion Optimization in Data-Driven P2P Video Streaming

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.
