This article examines the recent strategy adopted by the US television production industry in coping with the changing worldwide media environment. Developments in the USA include the commercial networks' declining audience share, the increasing penetration of cable TV, and spiralling production costs; abroad, the coming of age and increased sophistication of the televesion industry and the strengthening of programme import regulations are significant. Access to foreign markets is becoming critical to the financial equation of US producers and distributors of high-budget TV programmes. International co-production is the response to the new dynamics of world-wide television programming and a product of economic necessities.  相似文献

Project-driven manufacturing, based on the make-to-order or the build-to-order principle and predominant in small and medium-size enterprises (SMEs), calls for an efficient solution of large combinatorial problems, especially in such areas as task scheduling or resource management. This paper addresses the problem of finding a computationally effective approach to scheduling a new project subject to constraints imposed by a multi-project environment. A constraint programming (CP) modeling framework is discussed in the context of an efficient decomposition of the constraint satisfaction problem (CSP) and the evaluation of strategies for pruning the search tree. The proposed approach is illustrated through examples of its application to the evaluation of a new production order.  相似文献

This article assesses the telecommunications needs of developing countries and the possibility of using satellite communications to meet those needs. Three primary technological factors provide a guide to this application: small inexpensive satellite earth stations can provide a solution to the problem of limited ground facilities; satellites can operate in a broadcast and multiple acess mode as well as in a conventional point- to-point mode; and, the capacity required to support a single interactive digital terminal is about 1000 times less than that required to support a voice telephone and abput 1 000 000 times less than that required for video transmission. These factors lead to consideration of new forms of national networks based on satellites, microprocessors and small earth stations which do not follow the North American model. These new advanced forms of networks can co-exist with conventional voice networks, and can provide a realistic alternative for consideration by national telecommunications authorities.  相似文献

日前,随着中国液晶电视标准的出台,掀起了一阵液晶电视将取代等离子电视成为市场主流的舆论。等离子(Plasma Display Panel,PDP)电视和液晶(LCD,Liquid Crystal Display)电视市场之争,缘起决不是去年今年的事。其实早在2002年,就已经有了二者除了尺寸还要比拼谁的价格低的言论。激烈的等离子与液晶大战,只是市场竞争更加激烈的表现,而断言一方将替代另一方,在笔者看来,实在是为时过早。  相似文献

近年来信息技术的不断突破和发展给电视媒体带来了一场数字化的革命,数字化已经成为当今电视界不可阻挡的潮流。与传统的模拟电视相比,数字化电视最显著的特点是:信号质量更好且长距离传输和多代复制过程无损失,超大规模集成电路的大量应用使电视设备更轻便、功能更强大、功耗更低和价格更便宜。以一套基本的电视制作系统为例,如果是模拟的,它起码应包括:编辑放像机、编辑录像机、编辑遥控器、特技机、字幕机和调音台等,若换成数字化制作系统,只需一台数字录像机和一台非线性编辑设备。由于数字化技术的优势和相关成熟设备的不断推…  相似文献

在过去几千年中,人们通过积累经验,参考天上的星体来确定自己所处的方位,而今天,即使是在浓云密布的漆黑夜晚,人们也可以利用卫星定位系统准确地知道自己在地球上所处的位置。所以有人说,从利用自然天体到发射导航定位卫星是人类导航史上从自然王国走向自由王国的具有划时代意义的里程碑。  相似文献

The paper looks at the role of cognitive radio in TV whitespace and suggests that European and US policy makers have limited its exploitation because of a predominant focus on cognitive radio as a device that is primarily suited for unlicensed opportunistic spectrum access. The paper suggests that markets for pragmatically conceived cognitive radios can be safely exploited within the confines of licensed spectrum, rather than solely in the domain of unlicensed opportunistic scenarios. Both European and US policy perspectives are analysed as they pertain to both cognitive radios and the TV whitespace, identifying the contradictions and opportunities therein. The analysis shows that regulators have already formulated many of the policy tools necessary to create a coherent ecosystem for license-based exploitation of TV whitespace by cognitive radios and that there are opportunities for broadening the regulation of TV whitespace.  相似文献

In this article the alternative methods of regulating the cable TV industry are compared in terms of efficiency and consumer welfare. The effectiveness of each regulatory option in limiting any market power that cable operators may be able to exercise is considered in a framework which recognizes that both the market and government regulations are imperfect, costly and often do not operate in the public interest.  相似文献
