Query: A Novel Adaptation Method for HTTP Streaming of VBR Videos over Mobile
  Networks   Recently, HTTP streaming has become very popular for delivering video over
the Internet. For adaptivity, a provider should generate multiple versions of a
video as well as the related metadata. Various adaptation methods have been
proposed to support a streaming client in coping with strong bandwidth
variations. However, most of existing methods target at constant bitrate (CBR)
videos only. In this paper, we present a new method for quality adaptation in
on-demand streaming of variable bitrate (VBR) videos. To cope with strong
variations of VBR bitrate, we use a local average bitrate as the representative
bitrate of a version. A buffer-based algorithm is then proposed to
conservatively adapt video quality. Through experiments, we show that our
method can provide quality stability as well as buffer stability even under
very strong variations of bandwidth and video bitrates.
