By using SP algorithm and error correction code technology, a combating burst error and large capacity data hiding method for secret transmission was proposed based on images.

采用SP交织算法、纠错编码，给出了一种基于图像的抗突发误码的大容量数据嵌入隐秘传输方法。

Because of the limitation of their characteristic, video watermark technique has less hiding capacity, they can't meet the need of large data secret communication or information intercept controller.

然而数字水印由于其本身的特性限制，使得一般的隐藏量都很少，无法满足一些大数据量的秘密通信和信息获取控制方面的要求。
