虽然使用电视、收音机等传统方式收看奥运节目更加简单,但是这种方式有自己不可避免的局限性,电视节目是定时的并且不具备可回溯性,也就是说当我们想收看某个比赛的时候,就必须按时等在电视机前,否则就将错过这个节目,除非我们预先设定使用录像机等设备进行录制。但是使用网络这种方式就完全不同了,我们不但可以实时在线收看直播的比赛节目,也可以点播以前的比赛节目,收看内容和收看时间完全自主。
Although it is simpler to watch an Olympic program using television, radio and other traditional means, this approach has its own unavoidable limitations. The television program is timed and does not have traceability, which means that when we want to watch a match , You have to wait on the TV in time, otherwise you will miss the show unless we have previously set up a device such as a video recorder for recording. However, this is a completely different way of using the Internet. Not only can we watch live broadcasts online in real time, but we can also select previous matches, watch content and watch time completely.
