【摘要】 采用视频A/D(模拟/数字)芯片和FPGA(现场可编程门阵列)技术,实现了多路视频整合输入。该方案用MPEG-4专用编码芯片对多路视频进行编码,通过FPGA实现PCI桥,从而形成完整的多路视频编码器。实践证明,该方案具有效果好、方案灵活、性能价格比高等优点。更多还原

【Abstract】 This paper realized multi-channel audio/video input by virtue of A/D chip and FPGA chip , cording the multi audio/video by virtue of MPEG-4 encording chip, PCI bridge by virtue of FPGA. Multi-channel audio/video encoder was realized. Experimentation have proved that the scheme is good, function plasticity, high ratio between performance and price.更多还原
