SVCEval-RA: an evaluation framework for adaptive scalable video streaming

Wilder E. Castellanos, Juan C. Guerri, Pau Arce
2015 Multimedia tools and applications  
A video stream encoded with H.264/SVC consist of several layers (one base layer and multiple enhancement layers) each with different characteristics of quality.  ...  Multimedia content adaption strategies are becoming increasingly important for effective video streaming over the actual heterogeneous networks.  ...  In addition, our simulation framework enables the MGS (Medium Grain Quality Scalability) coding scheme (instead of CGS that is used in most simulation frameworks).  ...

Congestion-aware quality-adaptive streaming of scalable video

Robert Kuschnig
2012 ACM SIGMultimedia Records  
To improve the network efficiency and the scalability in terms of number of clients served, HTTP-based request-response streams can utilize HTTP proxies and caches.  ...  streams was developed, to estimate the influence of the system parameters and the network characteristics on the throughput performance. (5) A comprehensive evaluation of the HTTP-based request-response  ...  As a result, with each CGS layer the quality of the video increases. The second option of quality scalability is medium grained scalability (MGS).  ...
