宽屏幕彩色电视机是指屏幕幅型比(或称图像宽高比)为16:9的彩色电视机。大量试验表明:人眼水平、垂直方向视角的幅型比大约为16:9,因此宽银幕电影和未来的高清晰度彩色电视机均采用16:9幅型比的显示屏幕。目前市场上出售的宽屏幕彩电大部分来自日本一些公司,国内只有少数厂家生产这种彩电。日本最先在世界上研制了MUSE制高清晰度彩色电视制式,但它与美国的全数字化高清晰度彩电制式相比,仍有许多缺陷而不能大发展。几年前,日本开始利用地球同步卫星试播MUSE制高清晰度彩色电视,但是接收设备价格昂贵,一般消费者不敢问津,但又想享受高清晰度电视的乐趣,于是出现了一种普通清晰度的宽屏幕彩电。这种普通清晰度的宽屏幕彩色电视机采
Wide-screen color television refers to the screen aspect ratio (or aspect ratio) of 16: 9 color TV. A large number of experiments show that the aspect ratio of human eyes in the horizontal and vertical directions is about 16: 9, so the 16: 9 aspect ratio display screen is used for widescreen movies and future high definition color television sets. Most of the widescreen color TV sets sold on the market come from some Japanese companies. Only a few domestic manufacturers produce such color TV sets. Japan first developed the MUSE high-definition color television system in the world, but it still has many flaws compared to the US all-digital high-definition color television system and can not be greatly developed. A few years ago, Japan started to make use of the geostationary satellite pilot MUSE high-definition color television, but the receiving equipment was expensive. The average consumer did not dare to ask any questions, but wanted to enjoy the high-definition television. As a result, Degree of wide-screen color TV. This general definition of wide-screen color TV mining
