摘　　要：场消隐期作为应用电视有限资源的一部分，其开发潜力正逐渐为人们所重视。提出一种新型的综合数据传输业务的应用电视，将控制信号搭载在视频信号通道上运行，优化了控制信号传输线路，解决了时延问题，达到了利用电视信号逆程资源的目的，在真正意义上实现了单缆传输监控系统。As a part of the limited resource of television, VBI（ Vertical Blanking Interval）＇s potency is emphasized by people gradually. This paper introduces a new design scheme using a single coaxial-cable to transmit video signals and control signals simultaneously. It optimizes the transmission circuit for control signals and solves the problem of time-delaying, and achieves the goal of using television signal counter regulation resources. So that single cable transmission monitoring system is truly put into effect.
