Abstract
In order to guarantee the programs play correctly and protect the digital video copyright, this paper gets a method on high-definition video (HD video) online recognition with strong robustness through analyzing the TV monitoring system requirements and video characters, based on the DCT algorithm. This method will embed the watermark after obtaining the embedding positions by analyzing video frames. It can improve the robustness to compression, noise and filtering by using Arnold scramble and spread spectrum technology. It is a real-time measure to extract watermark and recognize it in HD videos. This method shows of good performance to online recognition in HD video’s watermark extracting and recognizing in theoretical analysis and simulation experiment.
