摘要：

Semantic reasoning is being increasingly applied in Digital TV as a means to provide personalized information services. The pioneering initiatives have opted to place the personalization engines in the service providers' side, because the semantic mechanisms exceed-byfar-the computational power of DTV receivers. Unfortunately, this approach has the drawback that it can expose data about the users' interests and preferences to commercial entities, raising severe legal and ethical obstacles. Moreover in a domain where most of the information is transmitted through broadcast, there are many cases of intermittent, sporadic or null access to a return channel, which make the personalization features unavailable if lodged remotely. With these problems in mind, this paper introduces an architectural approach to deliver personalized DTV services, downsizing a semantic reasoning process to match the capabilities of fixed and mobile receivers. Preliminary experiments are reported, showing up to what point the enhanced privacy and availability impinge on personalization quality.
