实时数字广播系统接口规范及设计

Standard and Design of Real-Time Digital Broadcasting System Interface

讨论了数字广播系统的特性 ,分析了宽带数字广播系统与其他通信方法之间的区别。目前 ,电话网与无线调频接入网是信息联接与通信的主要物理载体 ,但由于电话接入因特网存在一些固有的缺点 ,使得我们注意力转向宽带网络技术。文中讨论的重点是如何确定实时数字广播系统接口的规范 ,本系统是基于 Client/ Server模式来进行通讯 ,相互之间通过数据帧紧密相联。所以 ,接口的规范也就是数据帧的确定 ,在确定了数字广播系统的接口标准之后 ,给出了应用该标准所生成的一个实例。

The characteristics of a digital broadcasting system are discussed. The differences between wide band digital broadcasting system and other communication methods are distinguished. At present, phone and wireless frequency modulated nets are the main physical carrier of information linking and communication. Because there are some intrinsic drawbacks in access to Internet by phone net, attention should be paid to the wide band net technology. This paper emphasizes how to confirm the interface standard of real time digital broadcasting system. The system is based on the Client/Server mode in communication with each other, so it depends on the data frame. In brief, how to confirm the interface standard is how to confirm the data frame. When the standard of the digiting broadcasting system interface is confirmed, the system is realized.
