System architecture and interactivity model for mobile TV applications

ABSTRACT

Interactive services and applications for Mobile TV are considered to be one of the promising concepts that offer new opportunities for mass media, mobile and broadcast industry. This article explores the concepts of interactivity, interactive applications and system architecture aspects in interactive mobile TV. It investigates demands and constraints for the software platform of mobile TV, suggests possible solutions for them and proposes prototype software architecture for mobile TV based on this investigation and proposed solutions. Interactivity model for the interactive mobile TV applications is proposed that facilitate the evaluation of these applications to prospect the terminal and server side's requirements. This model has significance because it specifies the overall image of mobile interactive system that will be helpful for defining common application framework based on the user's perception.
