DVB-H in Denmark - Technical and Economic aspects | Kamel Haddad
| | Abstract | The demand for multimedia services including mobile TV to mobile handset is increasing rapidly. Mobile TV is nowadays delivered on point-to-point 3G cellular networks. Being unicast in nature, these networks remain an inefficient method for simultaneous delivery of TV services to a mass audience. An alternative to the 3G cellular network is the point-to-multipoint DVB-H broadcast network, which has been designed for the delivery of mobile TV on handheld terminals. This is considered to be ideal for content delivery to a large number of users and to cater for an increased demand for mobile TV services.
The purpose of this project is to investigate the possibility of deploying a DVB-H network in Denmark. The investigation is carried out by means of describing the general features of a DVB-H network. This includes technical constraints and network planning issues such as network topology, coverage, radio frequency and radio transmit power as well as a cost estimate of deploying a DVB-H network in Denmark.
In particular, this thesis addresses the theory behind DVB-H. Also, in this paper an analysis of the economy of the 3G cellular and DVB-H network is conducted to understand the benefit of DVB-H compared to the 3G network. Results show that mobile TV over 3G networks will neither be profitable nor sustainable as it fails to serve mass mobile consumers. Although 3G cellular networks can be upgraded to MBMS or HSDPA to deliver higher data rates and support a significant number of subscribers, it has failed to support millions of subscribers during busy hours. Despite the difference between the broadcast and cellular networks, research has shown that these networks can be combined for successful delivery of mobile TV service. In order to show the benefit of the combined networks, a network convergence business model is presented. An evaluation of the different existing mobile TV broadcast technologies is also discussed to understand the benefit of DVB-H compared to the existing technologies. The main concern for the broadcasters and mobile operators alike with regards to DVB-H is the cost associated with the implementation of DVB-H network infrastructure. Two case studies are presented to estimate and evaluate the DVB-H deployment cost in Denmark.
Furthermore, an analysis of the evolving market opportunity for mobile TV is presented and finally, recommendations for adapting DVB-H technology will be discussed, in the hope that this technology will be deployed in Denmark in the near future. | | Type | Master's thesis [Academic thesis] | | Year | 2007 | | Publisher | Informatics and Mathematical Modelling, Technical University of Denmark, DTU | | Address | Richard Petersens Plads, Building 321, DK-2800 Kgs.
