Abstract
In this paper, we focus on the perceptual quality assessment of network streamed video via P2P networks. In these systems, the most noticeable impairments are not bit-level distortions, nor packet losses (as they get repaired), but video chunk or frame level delays. A key module in a video player is the video playback controller that decides whether to wait for delayed frames (hence freezing the playback), or try to playback by concealing the missing data. A good design should be based on how users react to different frame delay scenarios and playback decisions. We carefully designed a set of subjective tests to sample user reactions, and discuss how our results can be used in the design of playback controllers.
