摘要
介绍了一种置于计算机或dvb网关内部的PCI接口插卡,该发送卡通过标准的DVB输出接口———异步串行口(ASI),可以将计算机内部的MPEG2传输流数据以一定的速率发送给各种数字视频设备,实现大规模并行数据广播的发送。介绍了通过发送卡实现这种海量传输的硬件实现方案及设计要点分析。
This paper presents a kind of board based on PCI, which is embedded in the computer or gateway. It can send MPEG2 TS datas to digital video devices at a certain speed through the standard interface of DVB named ASI and realize the large-scale paralled broadcasting technology. It introduces in detail the hardware scheme and the key points with the tranfer card implementing a great deal of data transmision.
