摘　　要：SDI over IP是一种将SDI信号进行IP化封装和传输,适用于广电制播传输领域的技术。本文介绍了SMPTE组织所提出的SDI over IP相关技术标准,然后基于传统的SDI实时制作系统架构,提出一个SDI与IP技术架构相融合的实时制作系统模型方案,并通过分析搭建一个可实际工作IP实时制作系统的技术需求,来进一步描述SDI over IP技术如何在电视台实时制作系统中的应用。SDI over IP is a kind of technology that encapsulates and transmits IP based SDI signals, it＇s suitable for the field of producing, broadcasting and transmission in TV station. This paper introduces the SDI over IP technology standard proposed by SMPTE organization, then puts forward a live production system model scheme which integrates SDI and IP technology architecture based on the traditional SDI live production system architecture, and do further description on applying SDI over IP technology in live production system of TV station by analyzing the technical requirements of building a working live production system.
