DTV: a client-based interactive DTV architecture

In this study we present a client-based architecture that supports time-shift Digital-TV (DTV) features (i.e., pause, replay and fast-forward) and interactive applications. We call this architecture DTV for Personalizable Interactive Digital-TV architecture. Our study focuses on devising effective techniques for managing the client’s data (e.g., textual, binary, and video/audio data) under the local resource constraints. We outline the challenges that DTV faces and sketch data and resource management policies that maximize the client’s QoS adaptively based on each individual viewer’s quality requirement. We present a prototype that have been built and describean array of applications that DTV can help realize.
