DVB传输流捕获系统的实现

The Implementation of DVB Transport Stream Capture System

研究了 DVB传输流实时捕获系统的结构及其实现方法 .该系统的硬件利用复杂可编程逻辑器件和总线接口芯片 ,实现了传输流与 PCI总线之间的接口 ,软件利用设备驱动程序将硬件采集的数据流传入计算机 ,同时保证了高速的数据交换速率 ,可以对捕获的数据流进行实时的处理 .该系统在 DVB的分析、测试、存储。

Investigate the structure and implementation of DVB transport stream capture system based on the principle of the system.The hardware realizes the interface between the transport stream and the PCI local bus by employing CPLD and Bus Interface Chip.The software sends the data stream to application through employing the device driver,ensures the high data exchange rate and real time data processing.The system is useful for the DVB analysis,test,store,edit and multiplex.
