To improve the performance of the existing video-in-video algorithm and the quantity of embedding frames,an effective video-in-video method was proposed,in which the data hiding and the encoding technology were used.In term of the data hiding,the difference between adjacent frames in the IntDCT domain was predicted by utilizing the inter-frame correlation,and then the difference histogram as a cover was used to embed the secret video.Meanwhile,the encoding was utilized to enhance the transmission efficiency and improve the error resilience ability of the secret video.The simulation results indicate that the proposed method can effectively increase the quantity of embedding frames and improve the quality of the secret video.The covert communication of the secret video based on the video is achieved.
