摘　　要：随着网络技术和多媒体技术发展,传统的广播电台导播装置仍采用电话耦合器的方式和引入CTI板卡和电话耦合器配合使用的方式,已不能很好的满足电台业务的需求.基于此,数字多路导播系统应运而生,基于包交换的IP通信技术构建新一代数字导播装置,可有效的解决传统导播装置面临的问题,满足电台和听众对热线电话形式的需求.数字多路导播服务器是导播系统的核心设备,本文设计并实现了基于Keygoe设备的数字导播服务器系统.采用模块化的方法,设计数字导播服务器系统结构,设计并实现了数字导播服务器系统中设备资源管理模块、策略执行模块、消息通信模块和界面呈现模块.With the development of network and multimedia technology, traditional radio station director device is still using telephone coupler or the method of combination with CTI boards and telephone Coupler, which cannot meet the needs of radio businesses. For this reason, digital multi-channel director system emerges. New generation of digital director device builded by IP communication technology based on packet-switching, can effectively solve the problems faced by traditional director device, meet the needs of radio stations and listeners. Digital multi-channel director server is the core of director systems device. This paper designs and implements a digital director server system based on Keygoe device. Digital director server system architecture is desiged with modular method. This paper presents the design and implement of modules in digital director server system, such as resource management module, policy enforcement module, message communication module, and user interface module.
