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D
解析 本空位于第四段段首，其后谈到了没有人真正知道(nobody really knows)消费者是否愿意为它(即移动电视)付费；此外，还谈到了其他两方面的不确定因素(there is further uncertainty in two areas)。因此，概括起来，该段主要谈论的就是“不确定性”；浏览选项可知，[D]为本题答案。该项中的关键词unclear与nobody really knows及uncertainty形成共现关系；此外，该项中的despite all this activity又是对上文的总结。[G]为本题的强干扰项，因为其中也谈到了uncertainty，但文章前三段的重点并不是The potential for mobile TV，故不能得出该项前半句的总结。
