近几年来,交互式电视一直是一个热点课题。交互式是指电视、电信和计算机业三者高度结合的通讯方式。随着这种新技术的出现,电视观众和电视节目提供者之间以及观众和电视之间的关系正在发生根本性的变化。据专家们预测:电视观众被动地接受广播部门提供节目安排的日子即将结束。电视观众可以通过向节目提供者返送信号来选择自己想看节目的内容和时间。而数字技术已使信号返送成为现实。如此一来,控制电视节目的就不再是节目提供者,而是电视观众了。
In recent years, interactive television has always been a hot topic. Interactive refers to the television, telecommunications and computer industry, a combination of three highly integrated means of communication. With the advent of this new technology, the relationship between television viewers and television program providers and between viewers and television is undergoing fundamental changes. Experts predict that television viewers will end their passive acceptance of programming provided by the broadcasting sector. TV viewers can choose what they want to see the content and time of the show by sending a signal back to the program provider. Digital technology has made signal return a reality. As a result, television programs are no longer program providers, but television viewers.
