Survey of Transportation of Adaptive Multimedia Streaming service in Internet

Abstract

Streaming media systems such as YouTube, Netflix, and Apple Music are reining the multimedia world with frequent popularity among users. A key concern of quality perceived for video streaming applications over Internet is the Quality of Experience (QoE) that users experience. Due to changing network conditions, bit rate and initial delay, the multimedia file freezes or provides poor video quality to the end users. Researchers across industry and academia have explored HTTP Adaptive Streaming (HAS), which splits the video content into multiple segments and offers the clients varying qualities. The video player at the client side plays a vital role in buffer management and choosing the appropriate bit rate for each segment of video to be transmitted. A higher bit rate transmitted video pauses in between whereas, a lower bit rate video lacks in quality, requiring a tradeoff between them. The need of the hour was to adaptively vary bit rate and video quality to match the transmission media conditions. Furthermore, the main aim of this paper is to give an overview on the state of the art of HAS techniques across multimedia and networking domains. A detailed survey was conducted to analyze challenges and solutions in adaptive streaming algorithms, QoE, network protocols, buffering, etc. It also focuses on various challenges on QoE influence ISSN 1943-3581 2017 www.macrothink.org/npa 86 factors in a fluctuating network condition, which are often ignored in present HAS methodologies. Moreover, this survey will enable network and multimedia researchers a fair amount of understanding about the latest happenings of adaptive streaming and the necessary improvements that can be incorporated in future developments.

Network Performance in HTML5 Video Connections

“…In this subsection, we present the most popular codecs which are supported by HTML5 [6] and will be used in our test benches. It is the standard used to provide DTT or webTV service and supports mobile devices.…”

“…This sort of service involves the requirement of knowing the equipment the users have. It is also important to know the kind of content is being transmitted as well as the most appropriate protocols in order to adequate the transmission parameters to reach good values of quality of service (QoS) and quality of experience (QoE) [6]. Problems in network capacity can limit the amount of data the users can receive and thus the quality of video [7].…”

Performance Study of Adaptive Video Streaming in an Interference Scenario of Femto-Macro Cell Networks

“…Authors in [13] introduced an extensive review of HAS techniques across multimedia and networking domains. They addressed the major issue that the users can perceive from the multimedia streaming, which is the QoE, along with the challenges that influence the QoS just like the variation of channel condition, which is normally ignored by the HAS technologies.…”

Social‐Aware Cooperative Video Distribution via SVC Streaming Multicast

“…However, previous cooperative recovery schemes did not take the hierarchical encoding structure of SVC into account, which may not lead to a significant gain to SVC-based video multicast. In other words, from the perspective of user's Quality-of-Experience (QoE) [14], simply boosting the transmission rate does not necessarily result in improvements in the user perception of the video quality [15].…”
