摘  要

 DVB是一种新型的电视广播系统，应用于九十年代末的创新技术，被誉为面向21世纪的广播技术革命。DVB提供了-套完整的，适用于不同媒介数字电视广播的标准系统。DVB又可以将图像、语音、文字及各种数据信息综合到一起播出，适用于无线广播、有线广播和卫星电视，是当前最为实用的一种数字视频广播。DVB分为三种，DVB-S(Satellite):采用11/12GHz卫星频段进行传输的DVB系统标准，广泛适用于各种转发器的频带和功放。 DVB-C(Cable):采用有线电视系统进行传输的DVB系统标准。DVB-T(Terrestrial):采用地面广播进行传输的DVB系统标准。本文主要论述了DVB系统的历史背景，系统仿真以及发展前景。

ABSTRACT

 DVB is one kind of new broadcast system, applies in the end of the 90's innovation technology, for is faced by the reputation the 21st century the broadcast technological revolutions. DVB has provided - the set completely, is suitable standard system which broadcasts in the different medium digital television. DVB may the image, the pronunciation, the writing and each kind of data message synthesizes broadcast together that, is suitable in the radiobroadcasting, the public address and the satellite TV, is the current most practical one kind of digital video frequency broadcast. DVB divides into three kinds, DVB-S(Satellite): Uses 11/12GHz satellite frequency band to carry on the transmission the DVB system standard, widely is suitable in each kind of transponder frequency band and the merit puts. DVB-C(Cable): Uses the wired television system to carry on the transmission the DVB system standard. DVB-T(Terrestrial): Uses the ground broadcast to carry on the transmission the DVB system standard. This article mainly elaborated the DVB system historical perspective, the system simulation as well as the prospects for development.
