为提高现有视频嵌入视频算法的性能和隐藏的视频帧数，提出一种基于编码和信息隐藏的高效视频嵌入视频算法。利用帧间的相关性，在IntDCT域进行相邻帧的系数预测，以预测的差值直方图为载体进行秘密视频的嵌入；对秘密视频进行编码预处理，增强传输效率并提高秘密视频抗误码的能力。仿真结果表明，该算法有效提高了隐藏的帧数和接收端提取秘密视频的质量，实现了秘密视频的隐秘传输。
為提高現有視頻嵌入視頻算法的性能和隱藏的視頻幀數，提齣一種基于編碼和信息隱藏的高效視頻嵌入視頻算法。利用幀間的相關性，在IntDCT域進行相鄰幀的繫數預測，以預測的差值直方圖為載體進行祕密視頻的嵌入；對祕密視頻進行編碼預處理，增彊傳輸效率併提高祕密視頻抗誤碼的能力。倣真結果錶明，該算法有效提高瞭隱藏的幀數和接收耑提取祕密視頻的質量，實現瞭祕密視頻的隱祕傳輸。

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 trans-mission 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 commu-nication of the secret video based on the video is achieved .
