C/S结构的局域网广播系统设计与实现
摘要：目前各类学校相继建起了通过无线发射的方式传播信息的局域广播电台，但是这种广播电台发射功率很小，只能小范围传播与接收，本文基于这个出发点，简要介绍了C/S结构的局域网的网络结构、功能特点、设备配置及可靠性管理，并通过网络知识和软硬件配置架构一套C/S结构的局域网广播系统。

第一章 前言
数字音频广播(DAB)技术的逐步成熟和计算机网络技术的迅速发展,为广播技术带来了一次历史性的变革,开创了广播电台全新的工作环境,架起了通向数字化信息时代的桥梁。传统电台的节目制作与播出基本上是彼此独立的,各种音源及制作好的各类节目均以各种磁带或光盘这种物理实体为载体,在录音室、编辑室与直播室之间交换使用,各种音频设备,大到调音台,小到CD机等,也是各自独立使用的。
目前,改变这一节目运作模式的是数字音频网络系统。数字音频网络系统的建立,极大地推进了广播电台的数字化、节目播控管理的自动化及节目制作方式的智能化,实现了对电台整体节目运作的集成。电台所要求的节目录制、新闻编辑制作、节目直播、广播播出等均可在网络上实现,大大提高了节目播出质量及运作效率,大幅度降低了节目的运作成本。
1.1 TCP/IP简介
TCP/IP协议是众多协议中比较完善的一种网络协议，在TCP/IP协议成为工业标准之前，它已经过了近12年的实际测试，TCP/IP协议实际上就是在物理网上的一组完整的网络协议，用与OSI同样的层次模型来描述TCP/IP网络协议组，则TCP提供了传输层服务，而IP提供了网络层服务，TCP/IP是一组协议的代名词，它还包含许多别的协议，其层次结构图1.1所示:

Chapter Preface
Digital Audio Broadcasting (DAB) technology, the gradual maturity and rapid development of computer network technology for the broadcasting technologies has brought a historic change, creating a new radio work environment, put up the way to bridge the digital information age . Traditional radio broadcast programming and is essentially independent of each other, and various audio and production of various types of programs are a good variety of magnetic tape or compact disc of this physical entity as the carrier, in the recording studio, editing room and between the live room exchange the use of a variety of audio equipment, large mixer, small enough to CD etc., but also independent use.
At present, the change in the mode of operation of this program is the digital audio network system. The establishment of digital audio network system, which greatly advanced the digital radio stations, program controlled the management of broadcast programming automation and intelligent way to achieve the overall program for the operation of radio integration. Required to record radio programs, news editorial production, live shows, radio broadcast, etc. can be implemented on the network, greatly improving the broadcast quality and operational efficiency, significantly reduce the operating costs of the show.
1.1 TCP / IP Introduction
TCP / IP protocol is a relatively complete a number of agreements as a network protocol, in the TCP / IP protocol as the industry standard before it has been nearly 12 years of actual testing, TCP / IP protocol is actually a group of the physical line a complete network protocol, using the same level with the OSI model to describe the TCP / IP networking protocol suite, TCP provides a transport layer services, while IP provides network layer services, TCP / IP protocol is a set of synonymous, it contains many other protocols, its hierarchical structure as shown in Figure 1.1:
