电视是一种直观的传输信息及文化娱乐工具。随着电视机广泛普及,人民生活水平及欣尝水准的提高,人们对电视的图像和音响效果的要求也就越来越高。人们不仅追求高清晰度大屏幕的彩色图象,也希望能聆听到高保真度的立体声电视伴音。目前一些技术光进的国家已经采用立体声电视广播,从而满足了人们对完美视听效果的艺术享受。在我国,现在还暂时不具备开播立体声电视的条件。设计一种能够以假乱真的模拟立体声电视伴音系统,可大为改善人们对单声逍电视伴音的感受,至少目前还是具有现实意义的。
Television is an intuitive tool to transfer information and culture and entertainment. With the widespread popularization of television sets and the improvement of people’s living standards and enjoyment, people’s requirements for television images and sound effects are also getting higher and higher. People not only pursue high-definition large-screen color images, but also want to hear high fidelity stereo TV sound. At present, some countries where technology advances have adopted stereoscopic television broadcasting, thus satisfying people’s artistic enjoyment of perfect audio-visual effects. In our country, we still do not have the condition to start the stereo TV temporarily. Designing a real-life analog stereo sound system can dramatically improve the way people experience the sound of a single Xiao Xiao TV, at least for now.
