“…On the other hand, the widespread usage of cellular networks, and the deployment of novel technologies and more powerful terminals associated to 3G networks has enabled Wireless Operators to offer higher quality contents. We have therefore a situation where operators, wireless and broadcast, may both aim to distribute quality contents like music and video, preferably to selected premium subscribers [1], and through the same type of device. For wireless networks, a technical problem still remains: radio resource usage for broadcasting a news bulletin or a major sports event is quite expensive for the scarce radio resources.…”

The increased demand for multimedia services by mobile end users in recent years have driven both Broadcast and Wireless Network operators to develop new systems and architectures for the deployment of such services. The proposed solutions are nonetheless limited either in terms of QoS or Capabilities to deliver new interactive services. This paper highlights strengths and drawbacks of the existing technologies in terms of QoS, Security and Mobility. In order to fill the gap between current solutions we propose a new architecture that builds itself on the synergies created by a heterogeneous network made of existing delivering technologies, such as 3GPP/MBMS and DVB, where services can be delivered to end-users in the most appropriate way for end-users and operators alike. A prototype implementation is further described.

“…In mobile devices such as personal digital assistants (PDAs) and multimedia cell phones [5], the processing resources, memory and power are all very limited, but the need for secure transmission of information may increase due to the vulnerability to attackers of the publicly accessible wireless transmission channel. The problem is further compounded by the fact that security algorithms can be very compute-intensive, which conflicts with the scarce resources available in such a mobile platform.…”

Abstract-TV is regarded as a key service for mobile devices. In the past, Mobile TV was often associated with broadcast transmission. However, unicast technology is sufficient in many cases, especially since mobile users prefer to access content on-demand, rather than following a fixed schedule. In this paper we will focus on 3G mobile networks, which have been primarily optimized for unicast services. Based on a traffic model we will discuss the capacity limits of 3G networks for unicast distribution of Mobile TV. From the results it can be concluded that the capacity is sufficient for many scenarios. In order to address scenarios in which broadcast is a more appropriate technology, 3GPP has defined a broadcast extension, called Multimedia Broadcast Multicast Service (MBMS). MBMS introduces shared radio broadcast bearers and has thus the capabilities of a real broadcasting technology. We will give a short overview about MBMS including a discussion on MBMS capacity. Since MBMS is primarily a new transport technology, additional application and service layer technologies are required, like electronic service guide and service protection. These mechanisms are standardized by the Open Mobile Alliance (OMA) and are favorably combined with MBMS or 3G unicast distribution in order to create complete end-to-end solutions. In order to optimize a system for delivery of broadcast services over 3G networks, the advantages of broadcast and unicast should be combined. We argue that hybrid unicast-broadcast delivery offers the best system resource usage and also the best user experience, and is thus favorable not only for broadcast delivery in 3G networks, but actually also for non-cellular broadcast systems like DVB-H or DMB.
