An estimation method of system cost, associated revenue and estimated profitability that applies to the broadcasting standards used in digital terrestrial networks is presented. The purpose of this research is to support and promote the adoption of innovative technologies that improve spectrum efficiency and flexible usage. The model presented should help key players to make choice on digital terrestrial broadcasting technologies driven by optimal investment cost and the techno-economic analysis. The results clearly show the early (in realistic multiple-multiplex cases even immediate) profitability of broadcast network if MPEG-4 and DVB-T2 standards are used.

The overview of Digital Video Broadcasting (DVB) standards is presented. Particular attention is devoted to standards for terrestrial broadcasting, DVB-T and the newest DVB-T2. The comparison between these standards is derived and the advantages of the DVB-T2 over DVB-T are emphasized.

This article presents an analysis of the key technology improvements of the second generation of Digital Video Broadcasting -Terrestrial (DVB-T2) over its first generation (DVB-T) and an estimation method of the new technology influence on the broadcasting business case used in digital terrestrial networks. This article addresses the current challenges in broadcasting wireless network design and strategic planning of ubiquitous media by taking the multidisciplinary approach. The model presented supports decision-making process driven by an optimal investment cost and the techno-economic analysis of digital terrestrial wireless technologies using innovation service diffusion Bass model. The method of estimating the benefits of advanced digital dividend exploits the capacity gained due to DVB-T2 technology novelties. The simulation results for Serbia show that the profitability of broadcast network is achieved in some cases already after 2 years if DVB-T2 standard is used.
