考研英語閱讀真題文章三十篇之十六

  A fuzzy picture

  THIS is a really exciting time-a new era is starting, says Peter Bazalgette, the chief creative officer of Endemol, the television company behind Big Brother and other popular shows. 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.

  Already, many mobile operators offer a selection of television channels or individual shows, which are streamed across their third generation networks. In South 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 Canale 7, a television channel, with a view to launching mobile TV broadcasts in Italy in the second half of 2006.

  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 .

  Despite all this activity, however, the prospects for mobile TV are unclear. 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. 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: DVBH, favoured in Europe; DMB, which has been adopted in South 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.

  In contrast, watching downloaded TV programmes on an iPod or other portable video player 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. That suggests that some shows better suit the download model, while others are better suited to real time transmission. The two approaches will probably coexist.

  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 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. In South Korea, a consortium of broadcasters launched a free to air DMB network last month, but the countrys 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.

  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 .
