近年来电视发生了很大变化。现在你可以坐在宽大的平面屏幕前,一瞬间就调出数百个频道。你可以停下来,重新观看直播,并使用个人视频录像机(如TiVo等) 录下你喜欢的节目。在有些国家,“点播”服务能使观众想看的时候就能看,不必等电视台决定播放的时候才能看。这些好处全得益于数字技术。数字技术明显地改变了电视,与此同时,电台也在发生变化,只是人们不太注意而已。电台也在走向数字化。 Television has undergone great changes in recent years. Now you can sit in front of a large flat screen and instantly bring up hundreds of channels. You can stop, watch the live stream again, and record your favorite shows using a personal video recorder (such as TiVo). In some countries, “on demand” services allow viewers to watch when they want to, without having to wait for the station to decide when to play. These benefits all benefit from digital technology. Digital technology has clearly changed the television, meanwhile, the radio is changing as well, just because people are not paying enough attention. Radio is also going digital.
