摘要
提出了一种基于数据库播出的新方法,即通过在播出和接收端设置相同类型的数据库,传输时将数据记录进行封装传输,接收端通过提取数据记录并利用预存的一些模板进行显示,从而很大程度上避免传输过程中的冗余数据,大大提高播出效率,有效利用了广播网络带宽。
A novel met ho d based on database is proposed in this article.The improved system sets two da tabases with the same type at the transmitter and the receiver respectively.Whe n transferring,several records are encapsulated and sent to network.By using t emplates saved at the receiver,received data packets are displayed.In this way ,large redundant data are avoided to a large extent,therefore,the broadcastin g efficiency is improved greatly and the network bandwidths are used efficiently .
