摘　　要：针对当前的运动视频数据传输方法因链路不均衡而导致数据传输误码率偏高、传输安全性较差的问题,提出一种基于条件随机场模型的运动视频数据传输方法。首先构建运动视频数据传输信道均衡模型,利用随机链路转发控制方法进行链路均衡调制;其次建立运动视频数据传输过程的波特间隔均衡调节模型,采用条件随机场模型对运动视频传输过程进行分簇聚类设计,实现运动视频数据传输过程的调制解调处理;最后提取运动视频数据的帧向量,实现运动视频数据的安全传输。实验结果表明,采用该方法进行运动视频数据传输的输出结果峰值信噪比较高,误码率较低和数据召回率较低,有效提高了运动视频数据传输的质量和安全性。In order to solve the problem of high error rate and poor transmission security caused by unbalanced link in current video data transmission methods,a conditional random field model-based data transmission method of video is proposed.Firstly,the equalization model of moving video data transmission channel is constructed.Secondly,the baud interval equalization regulation model of the motion video data transmission process is established.The conditional random field model is adopted to cluster the motion video transmission process,so as to realize the modulation and demodulation processing of the motion video data transmission process.Finally,the frame vector of moving video data is extracted to realize the safe transmission of moving video data.The experimental results show that the output results of motion video data transmission with this method have higher peak SNR,lower bit error rate and lower data recall rate,which effectively improves the quality and safety of motion video data transmission.
