Many Americans access information through the evening newscasts shown on mainstream television. Nevertheless, the technological developments that our society has experienced in the last decade are changing the traditional information-access paradigm. The number of Internet consumers has increased exponentially and, among many other habits, the World Wide Web is transforming the way in which users get entertained and informed. Aware of this reality, many broadcasters use their websites as baits to attract larger and more varied audiences and, in attempts to increase viewership, they host online programs that were first aired live on television. According to the current regulations in the U.S., those reshows need to include closed captions of at least the same quality as those originally delivered on television. This paper presents the main findings of a research project exploring how this applies to the case of the national evening newscasts uploaded to the websites of four major broadcasters. Results show that efforts are being made to provide good IP-delivered subtitles, but that there is still room for improvement in terms of completeness, placement and accuracy.

许多美国人通过主流电视台上播出的晚间新闻广播访问信息。尽管如此，过去十年来我们社会经历的技术发展正在改变传统的信息访问范式。互联网消费者的数量呈指数增长，除其他习惯外，万维网正在改变用户娱乐和了解信息的方式。意识到这一现实，许多广播公司将其网站用作诱饵，以吸引更多和更多的观众，并试图增加观众人数，他们托管了在线电视节目，该节目首先在电视上直播。根据美国当前的规定，这些重播节目必须包括字幕质量至少与电视上原始字幕相同的字幕。本文介绍了一个研究项目的主要发现，探讨了该项目如何应用于上传到四个主要广播公司网站的国家晚间新闻广播的情况。结果表明，人们正在努力提供优质的IP字幕，但在完整性，位置和准确性方面仍有改进的余地。
