In order to facilitate the development and proliferation of multimedia services in ubiquitous environment, a context-aware multimedia middleware is indispensable. This chapter discusses the middleware support issues for context-aware multimedia services. The enabling technologies for the middleware such as representation model, context management, and multimedia processing are described in detail. On top of our previous work, the design and implementation of a context-aware multimedia middleware, called CMM, is presented. The infrastructure integrates both functions of context middleware and multimedia middleware. This chapter also aims to give an overview of underlying technologies so that researchers in ubiquitous multimedia domain can understand the key design issues of such a middleware.

Conflict resolution in context-aware computing is getting more significant attention from researchers as pervasive/ubiquitous computing environments take into account multiple users and multiple applications. In multi-user ubiquitous computing environments, conflicts among user’s contexts need to be detected and resolved. Conflicts arise when multiple users try to access or try to have a control on an application. In this paper, the authors propose a series of algorithms to resolve conflict which can be embedded in different context aware applications like context aware devices (say TV, Mobile, AC, and Fan) and Context Aware Ambient (like Meeting Room, Living Room, Restaurant, Coffee Shop, etc.). The algorithms discussed in this paper make use of different tools like Probability, Fuzzy Logic, Bayesian Network and Rough set theory. In addition the algorithms utilize various factors like social, personal and environmental. The motto of this paper is to enable context aware applications to offer socialized and personalized services to multiple users by resolving service conflicts among users.
