“…Our previous work in [12] is the first study on HTTP streaming that supports VBR video by estimating both the instant bitrate and the instant throughput. In the context of managed IPTV networks, where the bandwidth is allocated in advance, the delay-quality tradeoff of VBR video is optimally achieved by switching some high-bitrate segments [13]. In [9], a buffer-based adaptation method is proposed for VBR video streaming by using a partial-linear buffer prediction model along with a strategy to select versions in different buffer ranges.…”

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.Index Terms-Variable bitrate video, adaptive streaming, DASH.

“…Various adaptation methods for HTTP streaming have been proposed over the past few years [7][8][9][10][11][12][13][14][15][16][17]. These methods can be roughly classified into two groups, throughput-based and buffer-based, each has its own strengths and weaknesses [18].…”
