播出应急可视化一键式切换优化算法

在电视节目的安全播出中,采用多路输入互为备份的方式,可以有效地避免因单点故障而导致整个频道的输出异常。特别是大型电视台,会采用主路、备路、备二、垫片四路输入,然而四路之间复杂的切换关系,使值班人员通常要花费较长时间判断,并且容易出错。通过可视化一键式切换优化算法,将原来复杂的人工判断交由计算机来完成,将原来需要组合判断的故障处理条件简为两画面之间的切换,并且明确给出“切”与“不切”的准确提示,加之可视化效果,使整个过程简单、明了、准确、快捷。最终通过程序验证,证实了算法在提高值班人员故障处理便捷性和准确性上有很好的效果。

Broadcast emergency visualization one-key switching optimization algorithm

In the television broadcast security, using multiple input mutual backup mode, can effectively avoid the output which led to the channel for a single point of failure exception. Especially TV big, will be using the main road, road, broadcast, gasket four inputs, and four switching relationship between the complex, the operator usually takes longer time to judge, and error-prone. Through the visualization algorithm one-key switching optimization, artificial judgment original complex intersection is realized by the algorithm, the original combination judgment fault processing conditions in order to switch between the two screen simple, prompt and accurate explicitly given "cut" and "no", and type of effect, make the whole process simple, clear fast, accurate. Finally through the program verification, confirmed that the algorithm improves the personnel on duty fault handling convenience and accuracy have very good results.
