Abstract
Conventional video traces (which characterize the video encoding
frame sizes in bits and frame quality in PSNR) are limited to
evaluating loss-free video transmission. To evaluate robust video
transmission schemes for lossy network transport, generally
experiments with actual video are required. To circumvent the need
for experiments with actual videos, we propose in this paper an
advanced video trace framework. The two main components of this
framework are (i) advanced video traces which combine the
conventional video traces with a parsimonious set of visual
content descriptors, and (ii) quality prediction schemes that
based on the visual content descriptors provide an accurate
prediction of the quality of the reconstructed video after lossy
network transport. We conduct extensive evaluations using a
perceptual video quality metric as well as the PSNR in which we
compare the visual quality predicted based on the advanced video
traces with the visual quality determined from experiments with
actual video. We find that the advanced video trace methodology
accurately predicts the quality of the reconstructed video after
frame losses.
