一种视频延长器、其控制方法及同轴视控传输装置
摘要：
本发明公开了一种视频延长器、其控制方法及同轴视控传输装置，包括：反控提取模块、闭环抑制模块、反控叠加模块以及视频驱动模块；其中，通过上述四个模块的相互配合，可以实现视频信号处于非消隐区时由视频信号输入端向视频信号输出端的放大与传输；当视频信号处于消隐区且进行反向控制时，可以将反向控制信号从视频信号输出端提取出来并传输到视频信号输入端，避免发送到视频信号输入端的反向控制信号再经视频驱动模块放大对当前正在进行的反向控制信号的提取过程的干扰，从而避免了正反馈效应。因此不需要采用具有模数数模转换功能的处理器即可实现传输视频信号与提取反向控制信号，从而可以使视频延长器的结构简单以及降低成本。
