U-multimedia framework: A secure and intelligent multimedia service framework based on context information in U-home

In the last few years, intelligent secured multimedia services play a vital role along with ubiquitous home environment (Park et al. in Lecture Notes in Computer Science, vol. 4097, pp. 660-670, [2006]; Lecture Notes in Computer Science, vol. 4159, pp. 893-901, [2006]; IEICE Trans. Inf. Syst. E89-D(12):2831-2837, [2006]; Lecture Notes in Artificial Intelligence, vol. 4252, pp. 777-784, [2006]; Lecture Notes in Artificial Intelligence, vol. 3801, pp. 313-320, [2005]). There are certain constrains and limitations in providing effective and efficient services in U-home. The mechanism and applications are integrated to realize such services. Three different kinds of ubiquitous multimedia services are proposed in the framework. Based on the temporal and spatial context information, the surrounding situations are recognized. The contexts are collected and well analyzed with the preconditions to provide the final services. The proposed framework provides efficient services in the multimedia based deices based on the current context information.
