高价蓝光影碟超清晰画质纯属骗人？They are supposed to offer films with the sharpest pictures and sound yet experienced in our living rooms。它们本来应该带来鲜亮的色彩并已经在我们的客厅中出现。But Blu-ray discs fail to live up to their expensive price tags, according to a consumer watchdog。Typically, the films cost around double the figure for an ordinary DVD, while many have a recommended price of more than ?20.但根据消费者监督机构的调查显示，蓝光影碟没有对得起它们昂贵的价码。蓝光影碟一般的推荐价格都在20英镑以上，这比普通DVD贵出一倍。However, a test by Which? found fewer than one in three Blu-ray films delivered an outstanding difference。然而，Which网站的调查说明，三分之二以上的蓝光影碟都没有带来明显的高质画面。Manufacturers have spent billions of pounds developing the high-definition Blu-ray technology and hope to sell millions of the sophisticated players needed to watch them。制造商们花了几十亿英镑发展蓝光技术，并希望能卖出几百万台用来观看这些影碟的播放机。However, many consumers have been sceptical about the promised extra image detail – with the result that sales have not taken off as expected。但是，可以看出很多消费者对许诺的超高画质产生了怀疑，因为销售额没有像预期的那样高。Which? pointed out that the marketing for the technology promises ‘the maximum high-definition experience’。Which网站指出，蓝光技术在营销过程中承诺了“极限高清画质体验”。However, it said there is little consistency in the definition offered by movies sold in Blu-ray – with a major gulf between the best and worst。但是，蓝光影碟能提供的画面质量并不能得到保证，最好的和最坏的差别很大。The organisation’s experts used two identical TVs to simultaneously watch Blu-ray and standard DVD versions of 17 films。该网站的专家用两个相同的电视屏幕播放了17部电影的蓝光碟和普通DVD。Around half of the Blu-rays offered only a marginal improvement。有一半的蓝光碟只是显示了稍好的画质。 （实习编辑：顾萍）
