摘　　要：利用视频解码芯片ADV7183A来完成模拟视频信号的采集量化,进而由ADSP-BF561完成视频数据的压缩,再通过PPI传输将压缩过的视频数据传送到由ADSP-BF537和LAN8187等芯片组成的网络传输模块,网络传输模块再将处理后的视频数据流通过组播和单播方式发送给指定用户。能够满足视频监控系统的实时性和远程化要求。The video decoder chip ADV7183A is used to collect and quantify analog video signals.The compression of video data is completed by the chip ADSP-BF561,and the compressed video data is transmitted to the network transmission module composed of ADSP-BF537 and LAN8187 chips through PPI transmission.Finally,the network transmission module sends the processed video data stream to the specified user through multicast and unicast.The proposed design meets the video monitoring system requirements for real-time and remote processing.
