Context-awareness has been recognized as a very desirable feature for mobile internet services. This paper considers the acquisition of context information for continuous services, i.e., services that persist in time, like streaming services. Supporting context-awareness for these services requires the continuous monitoring of context information. The paper presents the extension of a middleware architecture for the reconciliation of distributed context information to support context-aware continuous services. The paper also addresses optimization issues and illustrates an adaptive video streaming prototype used to test the middleware.
