Watching Video over the Web: Part 2: Applications, Standardization, and Open Issues

Understanding Timelines Within MPEG Standards

“…In this context, two main forms of media streaming can be distinguished: managed and unmanaged [1] [2] [29] [30]. Managed services, such as cable TV or IPTV, are quoted services that operate within privately owned walled-garden IP environments.…”

“…The main characteristics of managed and unmanaged streaming, a comparison between them, and their suitability in different scenarios can be found in [29] and [30]. Table III lists and compares the four main broadband delivery methods: downloading, progressive downloading, streaming and adaptive streaming.…”

Effect of system load on video service metrics

“…Cisco [1] predicts that network traffic volumes in the order of tens of exabytes are not that far off [2]; given that 90% of the bits transmitted on the Internet will be video related and that the number of consumers of these bits will soon exceed 1bn, monitoring customer experience will be crucial to safeguard revenues. The authors addressed the monitoring problem in [3]; an important open problem is how to predict the quality of video on a client's machine given the operational characteristics of the server delivering it.…”

Load-adjusted video quality prediction methods for missing data

“…Running software systems on general purpose platforms without realtime guarantees, with the expectation that one can safeguard revenues, is dichotomous. The video service level prediction work of [1] is a timely contribution given that Cisco [4] predicts that network traffic volumes in the order of tens of exabytes are not that far off, and 90% will be video related [5]. According to [1] a SL approach, for example Matrix Factorization [6] or Formal Concept Analysis [7], is preferable to developing and fitting complex analytical models for the different layers of soft/hardware in these complex systems.…”
