摘要
数字电视播出系统的可靠性直接反映整个系统的质量优劣,是确保能否进行安全、可靠的电视播出的关键。为了保障电视播出的安全与可靠性,必须对硬盘化播控系统进行双机热备份和使用有RAID技术的硬盘播出系统的数据备份设计;同时还介绍了数字电视播出播出系统软件的设计要求和数字电视设备的寿命分析。
The reliability of digital television broadcast system can directly reflect the quality of the system and is very critical for the proper function of the system. To ensure the safety and reliability of television broadcasting, the hard disk brocdcast system must be dual standby redundancy and the RAID technology should be used in the data spare design. The design requirements for digital television broadcast system software and the life analysis of the digital television equipment are also presented in this paper.
