互动电视或双向电视这种说法总的来说不能算太确切,因为互动电视并非一种相对于模拟电视或数字电视的独立存在的电视形式,而更多的表现为一种思维方式。完整意义上的互动电视是基于数字电视技术基础之上才能够得以实现的,且在现阶段,很大程度上依赖于有线网络的存在及其通信质量。而互动性从商业利益和沟通的角度出发,是数字电视最重要的功能,是海外电视界和工商界最为看重的。与之相比,实现高质影像与音效的传播变得次要。 The term interactive television or two-way television is generally not correct, as interactive television is not an isolated form of television relative to analogue television or digital television, but more of a way of thinking. A complete sense of interactive television is based on digital television technology can be achieved, and at this stage, depends largely on the existence of wired networks and their communication quality. In terms of business interests and communication, interactivity is the most important function of digital television and is valued most by overseas television and business communities. In contrast, the transmission of high-quality images and sound effects becomes secondary.
