This study aims to explore how the multiple system operators of cable television can remain their existing broadcasting advantages and cope with a strong, competitive telecommunications industry. As new and magnanimous data services are provided, multiple system operators, who have the last-mile advantage, are beginning to experience an increase in subscribers’ demands for bandwidth. First, thi...

Not so long ago, specific services and the associated networks were closely intertwined. Telecommunications networks delivered voice telephony. Broadcast systems delivered radio and television. The introduction of cable television and satellite transmission resulted in only a marginal increase in complexity. Today, one can no longer say that the service and the network are inextricably intertwi...

Television advertising revenues are falling after years of growth due, in part, to digital video recorder proliferation. We consider the television network‟s problem of how optimally to select, price, and order advertisements in order to maximize audience value. We propose that television networks should shift from managing and selling time to managing and selling viewer attention in order to e...

Actually, wealthy network services such as Internet protocol television (IPTV) and Voice over IP (VoIP) are expected to become more pervasive over the Next Generation Network (NGN). In order to serve this purpose, the quality of these services should be evaluated subjectively by users. This is referred to as the quality of experience (QoE). However, there are many issues that may impact user’s ...

In this paper we present NetCeiver, a lightweight and energy-efficient IPTV architecture that is fully compatible to existing digital television broadcast systems. It allows an easy convergence of digital television and IPTV. During the transition, consumers can thus benefit from the advantages of both technologies. NetCeiver pursues an integrated approach that combines zero-configuration algor...

This article describes a simulation model of a national network of television broadcasting stations. The performance of a station depends on its sitting and its antenna, on its radiated power and frequency, and on surrounding terrain and electromagnetic environment. All these factors can be analysed using the simulation model. Simulation can help in the maintenance of the existing television st...

This paper explores the emergence of direct linkages between the international economy and the state government of Baden-Württemberg, Germany. In the early 1990s BadenWürttemberg embarked on a plan in which the laender government took the lead in organizing a large-scale, high technology project for the development of interactive television. Creating a `network' between itself and major economi...

This paper presents the measurement results obtained in an extensive field test campaign developed in two large cities of Spain (Madrid and Bilbao) with the aim of characterizing the portable outdoor reception of digital terrestrial television (COFDM) and continue the studies carried out by the authors during the past years [1], [2].

Recently, coaxial cable networks have received much attention in the context of interactive application [1,2]. In countries with a high penetration of CATV (e.g. Belgium >90%), the cable network forms a viable alternative to classical telephone networks. Envisaged applications are telephony, interactive television, home-shopping, video-ondemand, high-speed Web browsing, etc. The interactive nat...
