摘　　要：DVB-RCS采用DVB广播和MF-TDMA回传工作方式,使主站和子站以非对称的链路速率实现双向通信。主要对DVB-RCS交互网的前向链路和后向链路通信体制进行了重点研究,并对其网控信令接收方案及子站入网过程作了深入分析。DVB-RCS is an satellite interactive communication system having dissymmetrical transmission velocity between home site and terminals. The forward interaction path adopts DVB broadcast channel and the return interaction path uses MF-TDMA channel. In this article, the communication organization about forward interaction link and return interaction link are researched, and deeply discusses the scheme about incepting the NCC signaling and the logon course of the terminals is deeply discussed.
