Abstract

The technical scheme provides a real-time digital video watermarking method based on an H.264 standard, comprising the following steps of: embedding watermarking information obtained after processing and coding and used as secondary enhancing information into a secondary enhancing information (SEI) field of each frame by analyzing the H.264 protocol standard and using available information resources in the H.264 standard; and ensuring robustness and nonvisibility of watermarking on the condition that video quality and a code stream format are not influenced. The real-time digital video watermarking method based on the H.264 standard can effectively resist frame deletion attack, has a simple realization mode, is used for solving various problems in the prior art that spatial synchronous distortion and photometric distortion can not be effectively resisted. The technical scheme can be used for judging copyright ownership or hiding, secretly carrying and transmitting information, and the like.
