Dynamic Interactive Multimedia Scenes in Mobile Broadcast Environments

Dynamic interactive multimedia scenes (DIMS) is the latest 3GPP multimedia standard aiming at the development and delivery of rich media services over mobile networks, specifically for the constrained devices. DIMS is a concept that encompasses a declarative format for audio-visual scene representation, as a composition of rich media objects with specific properties and behaviour. This paper focuses on the issues related to the delivery of Interactive TV like services with DIMS in mobile broadcast environments. We have investigated the system design parameters which would ensure better QoS for the subscribers. With the simulation results, we have setup guidelines for the selection of application layer FEC parameters, video coding settings and optimum base station transmit power. These guidelines assist in improving the overall rich media experience offered to the end-users.
