数字化广播是以数字音频技术为基础,计算机技术为辅助的广播,节目信号的传输与播出都是数字音频信号。由于数字信号失真小和噪声低,抗干扰能力强等,越来越广泛地应用于广播领域。数字化广播系统设计和模拟系统设计的最大不同之处是系统概念的更新。为此,在实现广播播出系统全数字化过程中需考虑以下几个问题。 Digital broadcasting is based on digital audio technology, computer technology for the auxiliary broadcast, program signal transmission and broadcast are digital audio signals. As the digital signal distortion and low noise, anti-interference ability, more and more widely used in the field of broadcasting. The biggest difference between digital broadcasting system design and analog system design is the updating of system concepts. To this end, the realization of radio and television broadcasting system in the whole process of digital to be considered the following questions.
