基于计算机平台的EFP系统特色研究

Research on property of computer-based EFP system

EFP——电子现场节目制作,是常用的电视节目制作方式之一。传统EFP系统由大量的硬件设备组合而成,系统构成复杂,操作使用繁琐,可靠性相对较低。而基于计算机平台的EFP系统将诸多硬件设备的功能集于一身,推出了全新的全能机概念,以单机的方式实现现场导播、硬盘录像、网络直播、延时播出、虚拟演播室等多种丰富实用的功能,节约了投资成本、减少了故障隐患、降低了劳动强度、提高了工作效率。伴随广播电视的数字化发展,基于计算机平台的EFP系统必将成为现场节目制作设备的主流。

EFP（Electronic Field Production） is one of the commonly - used ways of TV program production. The traditional EFP system is made up of plenty of hardware,which is complex in construction,difficult in operation and low in reliability.Computer - based EFP system is a highly integrated system,an all - round machine for live broadcast,hard disk storage of videos,network live broadcast,delayed broadcast and virtual studio. This system is low in cost and malfunction.It saves labor force and raises the effciency.With the development of digital TV programs,this system will play a major role in field program production.
