Recently, with rapid development of digital broadcasting technology, high-definition video service increased interest and demand. supplied mobile and image device support that improve 4~16 time existing Full HD. Such as high-definition contents supply, proposed compression for high-efficiency video codec (HEVC). Therefore, watermarking technology is necessary applying HEVC for protecting ownership and intellectual property. In this paper, analysis of prediction mode in intra frame and study feasibility of watermarking in re-encoding based HEVC. Proposed detect un-changed blocks in intra frame, using the result of analysis prediction mode.
