This document intends to describe a system overview of "Integrated Broadband Environment for Personalized TV Experience (IBEX)". The IBEX features three major goals: to release audience from time constraint scheduled by broadcasters, to provide seamless and adaptive access between TV and the Web, and finally, to securely personalize TV experience for individual audience. In order to achieve open framework, these viewpoints must be properly developed in conjunction with well-organized data models and system architecture based on de*facto standard technology. The IBEX will provide a prototype system model built on upcoming integrated broadband digital TV infrastructure. The IBEX also intends to provide a service model for the TV-Anytime framework.
