摘要 数字音频是高清晰度电视(HDTV)中非常重要的一环。在数字音频编解码中,心理声学模型的引入,大大降低了编解码的复杂度。对心理声学模型的基本原理及各心理声学模型在HDTV音频中的应用及其算法的详细阐述,有助于我们明确HDTV音频中心理声学模型的发展方向。 Digital audio is a very important part of high definition television(HDTV). In the digital audio coding and decoding, the introduction of the psycho acoustic model greatly reduced the complexity of coding and decoding. The through demonstration on its basic principle and application and algorithm in HDTV Audio helps to make clear its developing direction in HDTV Audio.
