Issue Date: | 2008 | Publisher: | IEEE | Source: | Proceedings of The 2nd International Workshop on Adaptive and DependAble Mobile Ubiquitous Systems (ADAMUS 2008). p. 557-563. | Abstract: | More and more, multimedia services are being accessed via fixed and mobile networks. These services are typically much more sensitive to packet loss, delay and/or congestion than traditional services. In particular, multimedia data is often time critical and, as a result, network issues are not well tolerated and significantly deteriorate the user’s Quality of Experience (QoE). We therefore propose a QoE optimization platform that is able to mitigate problems that might occur at any location in the delivery path from service provider to customer. More specifically, the distributed architecture supports overlay routing to circumvent erratic parts of the network core. In addition, it comprises proxy components that realize last mile optimization through automatic bandwidth management and the application of processing on multimedia flows. In this paper we introduce a transcoding service for this proxy component which enables the transformation of H.264/AVC video flows to an arbitrary bit rate. Through representative experimental results, we illustrate how this addition enhances the QoE optimization capabilities of the proposed platform by allowing the proxy component to compute more flexible and effective bandwidth distributions. | Document URI: | http://hdl.handle.net/1942/9164 | ISBN: | 978-1-4244-2100-8 | DOI: | 10.1109/WOWMOM.2008.4594883 | ISI #: | 000264285000072 | Category: | C1 | Type: | Proceedings Paper | Validations: | ecoom 2010 |
