The networks that are generically referred to as ?cable? today began their lives with a particular purpose: the distribution of television signals within a community. Given this history, cable networks have always operated under a regulatory regime separate from telephone networks?. Telephone systems are regulated as common carriers: telephone network services must be made available to all potential customers in a non-discriminatory fashion. Cable networks, in contrast, are not subject to the requirements of common carriage: cable system operators are under no legal obligation to make their networks available to anyone who wants to use them to distribute content (for example, a new television channel), and have in fact historically exhibited a high degree of vertical integration between conduit (cable networks) and content (TV channels). As ever more cable systems gain the capability to connect their subscribers to the Internet, this reality has sparked an intense legal wrangling and debate over the issue that is referred to as ?open access.? 1 Should cable systems with the capability to transmit data be required to allow any service provider to access customers through the cable network? Or is the current industry structure?in which service providers can only gain direct access to a cable system if they succeed in negotiating an agreement with the cable operator?a more appropriate way forward?

Delivering cable television to college and university campuses is maintained by a highly specialized industry which involves significant technological and logistical challenges. As campuses continue to contribute financial resources into improving their data networks, companies that provide campus cable services will need to offer services over data networks comparable to the existing services they offer over dedicated co-axial cable networks. This paper explores the business of providing cable services to university communities, describes the challenges these providers face and offers a glimpse into the future of IP-based desktop television.; by Paul K.

This book is a compilation of two recently completed works on the convergence of information and communication technology (ICT) (Singh and Raja 2008, 2009). Since then, convergence, the eroding of boundaries among previously separate ICT services, networks, and business practices, has accelerated and deepened. At the time these reports were written, convergence was already a reality and was picking up pace in low-income countries, as in the rest of the world. Now, as this introduction summarizes, broadband networks are reaching deeper into previously unserved areas. The growing number of people connected to broadband networks are consuming, sharing, and creating new multimedia content and applications. And they are doing this on handheld and portable devices that are less costly and do more than before. All sorts of users, governments, businesses, individuals, and ICT firms, are looking to cut costs while capturing greater value. Taken together, these trends indicate that convergence is set to accelerate even through the ongoing global economic downturn. Countries that enable convergence through appropriate policy and regulatory responses will realize significant benefits in terms of expanded access...

Internet Access : Regulatory Levers for a Knowledge Economy

Mustafa, Mohammad A.

Internet access depends on four critical players: First, providers of telecommunications infrastructure (bandwidth capacity) for international access to the global Internet backbone. Second, providers of national long-distance telecommunications transmission capacity (such as leased lines) to connect Internet service providers (ISPs) with one another and with international connectivity nodes. Third, providers of local loop access (narrowband and analogue, such as traditional copper wire connections, or broadband and digital, such as digital subscriber lines [DSL], cable television modems, and fixed wireless service). Fourth, ISPs, which provide Internet services to customers using these layers of networks. Expanding Internet access requires cooperative behavior by these players, and regulators have a key role in ensuring such behavior. A regulatory strategy for doing so focuses on promoting the telecommunications infrastructure, enabling viable ISPs, ensuring efficient pricing, maintaining appropriate service quality...

An Empirical Study of the Causes and Consequences of Mergers in the Canadian Cable Television Industry

Fonte: Quens University Publicador: Quens University
Tipo: Tese de Doutorado
Relevância na Pesquisa
This dissertation consists of three essays that study mergers and consolidation in the Canadian cable television industry. The first essay provides a historical overview of regulatory and technical change in the industry, and presents the dataset that I constructed for this study. The basic pattern of interest in the data is regional consolidation, where dominant cable companies grow over time by acquiring the cablesystems of small cable operators. I perform a reduced-form empirical analysis that formally studies the determinants of mergers, and the effect that acquisitions have on cable bundles offered to consumers. The remaining essays develop and estimate structural econometric models to further study the determinants and welfare consequences of mergers in the industry. The second essay estimates an empirical analogue of the Farrell and Scotchmer (1988) coalition- formation game. I use the estimated model to measure the equilibrium impact that economies of scale and agglomeration has on firms’ acquisition incentives. I also study the impact entry and merger subsidies have on consolidation and long-run market structure. The final chapter estimates a variant of the Rochet and Stole (2002) model of multi-product monopoly with endogenous quality and prices. Using the estimated model I compute the impact mergers have on welfare. I find that both consumer and producer surplus rise with acquisitions. I also show that accounting for changes both in prices and products (i.e....

El sector de la televisión en la ciudad de Pereira, es un campo que tradicionalmente se ha asociado a una empresa de amplia trayectoria y experiencia en el medio, la cual crea gran recordación dentro de los ciudadanos, Cable Unión S.A. En los últimos años este sector presenta una amplia competencia, presentándose en el mercado otras compañías como lo es EPM; aspecto este que en términos generales favorece al consumidor. No obstante, es posible encontrar rasgos comunes en estas empresas, siendo uno de estos y el principal objetivo de esta investigación, el de las conexiones fraudulentas o contrabandos por parte de algunas familias Pereiranas que acuden a este delito para poder tener acceso a la televisión por cable. Por lo anterior, la investigación se encaminó a indagar sobre los efectos e impactos socioeconómicos, que trae consigo el adoptar este servicio de forma ilegal. Además permite confrontar el impacto financiero que sufren las organizaciones durante un periodo en particular. De esta manera, la metodología aplicada en la investigación se basó en un estudio descriptivo – explicativo, en donde identificados y analizados los comportamientos de los usuarios de televisión por cable, se genera un análisis comparativo de los costos que estas empresas presentan por motivo de las conexiones fraudulentas...

Ponencia que trata el futuro de lo audiovisual, en cuanto a telesociedad y teleciudadano. Se basa en varias obras; una de ellas escrita por A.H Beck sobre las Comunicaciones (1962), la cual no pronosticaba ningún futuro a la televisión en colores y que las conexiones por satélite no reemplazaría al cable trasantlántico. La realidad presentada aquí confirma otra cosa. Una enorme confusión, disparidad de normas, obsolescencias rápida de aparatos, nuevos instrumentos con nuevas aplicaciones, retraso de las sociedades frente al furor tecnológico. Explica que la sociedad parcelaria se transforma en sociedad global gracias a la red numérica con integración de servicio (R.N.I.S). Las aplicaciones de la informática se expanden en esta época, y lo digital está reemplazando lo analógico. Examina en detalle fuentes como: textos, informática, sonido, teléfono, imágenes y televisión. Dentro de los textos se refiere a las bases de datos informáticas, bancos de datos, bases de datos Videotex, base de edición CD/ROM. En cuanto imagen y sonido, señala que la introducción de lo digital en estos aspectos logró darles mejor calidad. También indica que las normas de los sistemas de televisión: NTSC, PAL, y SECAM, están por desaparecer porque son insuficientes. Igualmente...

Memoria (licenciado en ciencias jurídicas y sociales); No autorizada por el autor para ser publicada a texto completo; En esta tesis se intentará dar una visión general a la situación que enfrenta la televisión por cable en el país en cuanto al tema de la censura. Creemos que este trabajo se hace necesario pues el tema no ha dejado de estar presente, con más o menos fuerza, en el debate nacional de la última década y no se han elaborado obras que traten en profundidad el problema. Por esto último es que esta memoria estará obligadamente revestida del carácter de “objetiva” ya que, como lo dijimos, no existen libros o tesis sobre la censura en la televisión por cable y la mayoría de las interpretaciones de las leyes, e incluso algunas clasificaciones y definiciones son originales de los autores

Este trabajo analiza las diferentes gamas de producto de los segundos operadores de cable españoles, aglutinados en torno a la AOC y ONO. Tras una gran escasez de canales temáticos en castellano, el lanzamiento de las plataformas digitales en 1997 ha promovido una abundancia en contenidos de este tipo, accesibles también para los operadores de cable. De momento, los cableoperadores españoles tienen escaso poder en la negociación de contratos de difusión con los proveedores de canales, por lo exiguo de su mercado, y desembolsan precios altos por los canales que difunden. Por otra parte, los operadores de cable españoles se enfrentan ante el reto de flexibilizar sus ofertas tradicionales de paquete básico, para permitir al suscriptor una mayor capacidad de elección, a la vez que promueven las sinergias entre los servicios de televisión y los de teléfono e Internet; This paper analyzes the different ranges of product of the second Spanish cable operators, AOC and ONO. After an extraordinary shortage of specialized channels in Spaniard, the exit to the market of satelites DBS (CSD y Vía Digital) in 1997 has promoted a great abundance in tematic contents. For the time being, Spanish cable operators have disburse high prices by the channels they transmit. On the other hand...

Using an empirical framework based on the Mussa-Rosen model of monopoly quality choice, we calculate the degree of quality degradation in cable television markets and the impact of regulation on those choices. We find lower bounds of quality degradation ranging from 11 to 45 percent of offered service qualities. Furthermore, cable operators in markets with local regulatory oversight offer significantly higher quality, less degradation, and greater quality per dollar, despite higher prices.

Background: Rates of childhood overweight and obesity have increased dramatically across Latin America in recent years. In Honduras, the problem is more common among children of upper and middle socio-economic status (SES). Evidence suggests that television advertising of high-energy-density (HED) foods may be associated with increased rates of childhood overweight and obesity.

Objective: The purpose of this study was to characterize the advertising of foods during television programming that targets school-age children in Honduras.

Methods: Content analysis was performed on four different television stations accessible to children in Honduras, including one broadcast station and three cable networks. Programming for each station was observed and recorded for one complete week, during after-school hours (defined as 1:30 pm to 5:30 pm, Monday through Friday). Eighty hours of programming were recorded and analyzed. Foods were categorized as being high in energy density or not (HED or non-HED).

Results: A total of 2271 advertisements aired during the observation period; roughly half of these (49.3 percent) were product advertisements. Of the 1120 product advertisements...

Determining the feasibility of a method for improving bandwidth utilization of cable networks

While the cable television industry has made significant investments in infrastructure to improve the number and quality of services delivered to their end customers, they still face the problem of limited bandwidth of signals down "the last mile" of coaxial cable to the subscriber premises. This thesis investigates an approach devised by the author to overcome this limitation. The method involves clustering of channels in both the upstream and downstream directions in a DOCSIS compliant cable system. A model of this approach is made and the theoretical maximum throughput is calculated for several scenarios. Results are compared to performance of existing systems. It is found that proposed approach yields significantly more throughput for a given RF bandwidth than others in the comparison.

Credibility on cable news: An Examination of the factors that establish credibility in newscasters

This study investigates the factors that contribute to and hinder a cable newscaster's establishment of credibility with their audiences. Considerations were made for political factors, exposure to newscasters, para-social relationship strength and visual credibility. A survey was administered online that obtained a sample of 139 participants. Findings suggest that audience members reporting high levels of exposure to newscasters tended to have higher credibility perceptions. The ability to recognize a newscaster was not a significant indicator of credibility perceptions. Newscasters that were perceived to have liberal political views tended to be perceived as more credible than those perceived as having more conservative views.
