Exploiting contexts with house log for value-added smart TV services

We have been studying log contexts using large-scale house log collected in home network system (HNS). A log context is defined with both the current and past situations of a house, where the current situation is characterized by the current status of an appliance (or a sensor), while the past situations are derived from the house log. In this paper, we propose context-aware services for smart TVs using the log contexts within HNS. We first present three different types of log contexts derived from smart TV. We then discuss value-added services using such log contexts, assuming that a smart TV is integrated with HNS.
