Abstract
Video traces containing the sizes and (PSNR) qualities of the individual
frames of a video encoding are a convenient video representation
for the evaluation of video networking mechanisms. These video traces
can be used to find the frame loss probabilities of a lossy networking
mechanism, but can not give the PSNR video quality after lossy network
transport. To date the video quality after lossy network transport
could only be determined through experiments with actual video or
by approximating the quality of the frames affected by a loss with
some low PSNR quality. In this paper we introduce and evaluate offset
distortion traces with which the video quality after lossy network
transport can be accurately determined without requiring experiments
with actual video. We explain how the offset distortion traces can
be used by networking researchers without equipment or experience
in video signal processing to accurately evaluate video networking
mechanisms in terms of the PSNR video quality.
