Abstract:
Due to the explosive growth of the mobile devices and development of the network technologies, HyperText Transfer Protocol (HTTP) adaptive streaming has become a new trend in video delivery to provide efficient multimedia streaming services. Another important development is the provision of high quality contents, such as Ultra High Definition (UHD) videos. UHD content supports longer Group Of Pictures (GOP) size, as well as higher spatial resolution and higher frame rates. Due to these characteristics, the UHD content is characterized by the longer segment duration and higher bandwidth requirements in HTTP adaptive streaming system. In an HTTP adaptive streaming system, the long segment duration, which is the characteristic of UHD content, degrades the responsiveness to network fluctuations. It increases the video stalling period and degrades the user Quality of Experience (QoE). In this paper, we propose the segment duration based HTTP Adaptive streaming scheme for UHD contents. In our scheme, we assign different segment duration based on each quality level and propose the rate adaptation scheme to improve the QoE for UHD content. Using the simulation, we prove that our scheme significantly reduces the playback discontinuity.
