摘要
场消隐期作为电视系统有限资源的一部分,其空余资源中可插入多种形式的数字信号。以单片机为开发平台,将控制信号搭载在视频信号通道上运行,简化了控制信号传输线路。该单缆传输线路设计方案不影响电视的正常播放,也不增加电视的传输带宽,从而达到了有效利用电视信号逆程资源的目的。
VBI（ Vertical Blanking Interval）is a part of the limited resource of television, in which various digital signals can be inserted. Based on MCU, this paper introduces a design scheme using a single coaxial-cable to transmit video signals and control signals simultaneously. This kind of transmission circuit doesn＇t affect the application television broadcast normally and doesn＇t increase video signal bandwidth additionally. It promotes the transmission more efficiently and economically.
