Fusion of digital television, broadband Internet and mobile communications—Part II: Future service scenarios

Abstract

SUMMARYThis is the second part of the tutorial paper following the previous tutorial paper describing enabling technologies in digital video broadcasting (DVB) system. The paper presents the current and future operational scenarios for DVB via satellite (DVB-S) system. Review of the current state-of-the-art technologies consisting of integration of broadband Internet and mobile communications and integration of broadband Internet and DVB are given. The future operational scenarios emphasize the fusion of DVB systems with other technologies in terms of network fusion and terminal fusion. For satellite service scenarios, it also takes into consideration mobility management and standard quality-of-service mechanism issues, such as integrated services and differentiated services. Several research directions for providing seamless services regardless of network, access technology and terminal in the fusion network are also highlighted in this paper.

The spatial distribution of broadband providers in the United States: 1999–2004

“…Because the rollout of cable and DSL continues to be less expensive in urban areas, primarily due to economies of scale, Greenstein (2005) suggests that these platforms will always favor urban areas. Until wireless broadband, satellite broadband or broadband over power lines (Gillett, Lehr, & Osorio, 2004; Lehr, Sirbu, & Gillett, 2006;Liang et al, 2007) becomes more cost-effective, or a newer technology emerges that allows for an efficient and economical retrofitting of existing rural infrastructures, the supply of broadband will remain lower in rural and remote areas. Finally, the broadband deployment index developed in this paper shows that broadband regions are not all alike.…”

Application of Bismuth‐Impregnated Mesoporous Silica to the Photochemical Oxidation of Methylene Blue: An Example of Nanoparticle Autocatalysis

“…Interactivity is a key issue in modern telecommunication networks even in traditional distribution services like TV or radio 1. Modern satellite services require two‐way interactive connections.…”
