读入视频，将视频转换成JPG格式的图片，并获取所需要的图片。(Read video,convert video to images and capture needed pictures.)

BCH(15,11,1)+交织编解码matlab代码(BCH (15,11,1) with interleaver matlab code )

说明：  通带截止频率 =2 4k rad/s，阻带截止频率 =2 8k rad/s，通带波纹系数 =0.3dB, 阻带波纹系数 =50dB,采样频率fs=20000Hz。(The digital filter are the digital signal processing important content, the digital filter may divide into IIR and the FIR two main kinds. As for the IIR digital filter design, we need the help of analog prototype filter, and then transform analog filter into digital filter.)
