摘　　要：ASI接口为TS流传输标准接口,具有传输速度快、准确度高、可靠性好等特点,被广泛应用在广播电视系统中。针对现阶段计算机一般不具有ASI接口,无法与ASI设备直接进行数据交换的问题,设计了基于FPGA IP核技术的ASI发送系统。相对于以前的实现方案,该设计具有结构简单、性能出色、成本低的特点。测试结果表明,该发送系统实现了TS流数据从计算机到广播电视设备的稳定传输,满足使用要求。As a standard interface of TS stream transmission, ASI features high speed, high accuracy and good reliability, thus it is widely used in broadcast TV systems.Aiming at the fact at present, the computers are not equipped with ASI interface, it is impossible to do data exchange directly with ASI equipment, thus the ASI transmitting system based on FPGA IP core has been designed. Comparing with previous implemen- ting strategies, the design is in simple structure, low cost and offers excellent performance. The test result indicates that the system implements stable transmission of TS stream data from computer to broadcast TV equipment on demand.
