下一代电视机将安装一种帮助那些因为不会设定盒式录象机(VCR)的时钟而无法录节目的人的微小芯片。GEC-Plessey公司已经设计出的一种芯片是从电视文字广播的内容中取出统一的节目日期和时间(UDT)信号,然后根据它来相应地设定录象机的时钟。这种芯片还会通过提取出隐含在电视信号中的广播网络识别而自动地把录象机调到相应的电视频道。 Next-generation TVs will be equipped with a tiny chip that will help those who can not record a program because they will not set the clock for a video cassette recorder (VCR). One chip that GEC-Plessey has designed is to take a unified program date and time (UDT) signal from the contents of the teletext and then set the video recorder clock accordingly. The chip also automatically transfers the video recorder to the corresponding television channel by extracting the broadcast network identification implicit in the television signal.
