模拟式彩色电视技术发展至今,已经有近50年的历史。随着科学技术的进步,彩色电视技术工作者围绕图像质量、伴音质量水平的提高与改善,进行了大量卓有成效的工作。一些大屏幕彩色电视机的技术水平已经达到相当高的水准,图像质量有了很大的改进与提高。但受各种条件的制约,这种模拟式彩色电视机在图像清晰度等方面不可能有质的飞跃,只是改善图像质量主观效果,因此下一代彩色电视机将向数字
Analog color TV technology so far, has been nearly 50 years of history. With the progress of science and technology, color TV technicians have done a lot of fruitful work on the improvement and improvement of image quality and sound quality. Some large-screen color TV technology has reached a very high level of technology, image quality has been greatly improved and improved. However, due to various conditions, this analog color TV can not make a qualitative leap in terms of image sharpness, but only improves the subjective effect of image quality. Therefore, the next generation of color television sets will shift to digital
