PURPOSE: An integrity authentication of H.264 video contents and a copyright protection method thereof based on non-blind watermarking are provided to extract watermarking for efficient integrity and copyright and efficiently protect the contents and video data. CONSTITUTION: A watermark generates after extracting a specific value from a video contents by using an intra and an inter prediction mode. The count value is inserted after quantizing the difference value of the watermark. The integrity is approved by encoding a secret key after extracting bits composing of the watermark. The intra prediction mode uses the similarity between a macro block and a sub block.
