In a standard UPnP-AV scenario, multimedia content provided by a Media Server device is streamed to Media Renderer devices by the initiation of a Control Point. However, there is no provisioning of context-aware multimedia content customization. This paper presents an enhancement of standard UPnP-AV services for home multimedia environments regarding context awareness. It comes up with context profile definitions, shows how this context information can be queried from the Media Renderers, and illustrates how a Control Point can use this information to tailor a media stream from the Media Server to one or more Media Renderers. Moreover, since a standard Control Point implementation only queries one Media Server at a time, there is no global view on the content of all Media Servers in the UPnP-AV network. This paper also presents an approach of multimedia content integration on the Media Server side that provides fast search for content on the network. Finally, a number of performance measurements show the overhead costs of our enhancements to UPnP-AV in order to achieve the benefits.}, address = {Cairo}, doi = {doi:10.1155/2008/835438}, language = {EN}, pdf = {https://www.itec.aau.at/bib/files/Context-Aware UPnP-AV Services for Adaptive Home Multimedia Systems.pdf}, publisher = {Hindawi Publishing Corporation}, url = {http://www.hindawi.com/journals/ijdmb/volume-2008/} }
