Quality of Service (QoS): Measurements of Video Streaming

TL;DR

This paper evaluates the quality of service for various video formats on social clouds, focusing on how resolution, bitrate, and storage size impact user experience during video sharing and streaming.

Contribution

It provides empirical measurements of QoS metrics across different video formats, highlighting the trade-offs between compression, quality, and loading times.

Findings

Higher compression reduces quality but improves load times.

Different formats vary significantly in QoS performance.

Optimal format selection depends on balancing quality and bandwidth.

Abstract

Nowadays video streaming is growing over the social clouds, where end-users always want to share High Definition (HD) videos among friends. Mostly videos were recorded via smartphones and other HD devices and short time videos have a big file size. The big file size of videos required high bandwidth to upload and download on the Internet and also required more time to load in a web page for play. So avoiding this problem social cloud compress videos during the upload for smooth play and fast loading in a web page. Compression decreases the video quality which also decreases the quality of experience of end users. In this paper we measure the QoS of different standard video file formats on social clouds; they varied from each other in resolution, audio/video bitrate, and storage size.
