A Study on the Personal Program Guide Technique Within Ubiquitous Media Community Environment Using Multi-band Sensor Gateway

摘要

The media community service and user interface that can be supported in an ubiquitous environment is a basis for sharing through various media informations and personalized service. Experiments on the conceptual and technical elements and its application were carried out in this study. Some mobile devices, which were equipped with sensor network with a 900 MHz, 2.4GHz frequency substitution and a media server, which was equipped with sensor gateway for arbitration of each media device, were used to establish a multi-substitution ubiquitous media community environment. Under such an environment, the context information of a device was exchanged with another through a gateway in a media server and each device was able to interwork by context information generated on a different mobile device, in a different substitution, effectively.
