问题     "This is a really exciting time — a new era is starting, " says Peter Bazalgette, the chief creative officer of Endemol. He is referring to the upsurge of interest in mobile television, a nascent industry at the intersection of telecoms and media which offers new opportunities to device-makers, content producers and mobile-network operators. And he is far from alone in his enthusiasm.
    Already, many mobile operators offer a selection of television channels or individual shows, which are "streamed" across their third-generation (3G) networks. 41.______.
    Meanwhile, Apple Computer, which launched a video-capable version of its iPod portable music-player in October, is striking deals with television networks to expand the range of shows that can be purchased for viewing on the device, including Lost, Desperate Housewives and Law & Order.
    42.______. For a start, nobody really knows if consumers will pay for it, though surveys suggest they like the idea. Informa, a consultancy, says there will be 125m mobile-TV users by 2010. But many other mobile technologies inspired high hopes and then failed to live up to expectations. And even if people do want TV on the move, there is further uncertainty in two areas: technology and business models.
    At the moment, mobile TV is mostly streamed over 3G networks. But sending an individual data stream to each viewer is inefficient and will be unsustainable in the long run if mobile TV takes off. 43.______
    44.______. That suggests that some shows (such as drama) better suit the download model, while others (such as live news, sports or reality shows) are better suited to real-time transmission. The two approaches will probably co-exist.
    Just as there are several competing mobile-TV technologies, there are also many possible business models. Mobile operators might choose to build their own mobile-TV broadcast networks; or they could form a consortium and build a shared network; or existing broadcasters could build such networks.
    The big question is whether the broadcasters and mobile operators can agree on how to divide the spoils, assuming there are any. Broadcasters own the content, but mobile operators generally control the handsets, and they do not always see eye to eye. 45.______.
    Then there is the question of who will fund the production of mobile-TV content: broadcasters, operators or advertisers? Again, the answer is probably "all of the above".
[A] So the general consensus is that 3G streaming is a prelude to the construction of dedicated mobile-TV broadcast networks, which transmit digital TV signals on entirely different frequencies to those used for voice and data. There are three main standards: DVB-H, favoured in Europe; DMB, which has been adopted in Korea and Japan; and MediaFLO, which is being rolled out in America. Watching TV using any of these technologies requires a TV-capable handset, of course.
[B] In contrast, watching downloaded TV programmes on an iPod or other portable video players is already possible today. And unlike a programme streamed over 3G or broadcast via a dedicated mobile-TV network , shows stored on an iPod can be watched on an underground train or in regions with patchy network coverage.
[C] In Korea, television is also sent to mobile phones via satellite and terrestrial broadcast networks, which is far more efficient than sending video across mobile networks. In Europe, the Italian arm of 3, a mobile operator, recently acquired Channel 7, a television channel, with a view to launching mobile-TV broadcasts in Italy in the second half of 2006.
[D] Despite all this activity, however, the prospects for mobile TV are unclear.
[E] Assuming the technology and the business models can be sorted out, there is still the tricky matter of content.
[F] In Korea, a consortium of broadcasters launched a free-to-air DMB network last month, but the country’s mobile operators were reluctant to provide their users with handsets able to receive the broadcasts, since they were unwilling to undermine the prospects for. their own subscription-based mobile-TV services.
[G] The potential for mobile TV is vast, in short — but so is the degree of uncertainty over how it should actually be put into practice.

选项

答案C

解析 浏览文章可知,本文谈论的是移动电视技术,推测文章可能涉及这项技术发展的现状及前景。本空位于第二段末,空格前的句子为该段的主题句,主要讲了许多移动网络运营商已经通过3G网络用流媒体的方式提供一些电视节目。因此,按照文章的行文习惯,空格处应该对该主题进行论证。浏览选项可知,[C]中谈到的韩国用卫星和地面广播网将电视节目传送给移动电话以及意大利3G移动运营商买下电视频道的例子正是对第二段主题句的论证,故该项为本题答案。
