基于IP技术的葛洲坝高清数字电视前端系统构建

Construction of High Definition Digital TV Front-end System of Gezhouba Based on IP Technology

数字电视前端平台是广播电视转播系统重要的核心组成部分,传统ASI接口架构的前端系统已无法满足日益更新的业务和技术需求。基于IP化的数字电视前端平台具备结构简单、灵活、扩展性好等特点,分析IP化数字电视前端系统相比传统ASI架构的优点,结合葛洲坝数字电视前端系统构建实际,对基于IP技术改造数字电视前端进行探讨。

The digital TV front-end platform is an important core component of the radio and television relay system.The front-end system of the traditional ASI interface architecture can no longer meet the increasingly updated business and technical requirements.The IP-based digital TV front-end platform has the characteristics of simple structure,flexibility,and good scalability.The advantages of the IP-based digital TV front-end system compared with the traditional ASI architecture are analyzed.Combined with Gezhouba s digital TV front-end system construction practice,the transformation of digital TV front-end based on IP technology is discussed.
