Abstract

The embodiment of the invention provides an HEVC-based video watermark processing method and device, and the method comprises the steps: carrying out the preprocessing of watermark information, so asto obtain a plurality of run sequences; carrying out HEVC coding on the video data, and obtaining coefficient blocks obtained in the coding process of an I frame; And obtaining a video code stream containing the watermark by using the coefficient block and the plurality of run sequences. The watermark information is preprocessed, and the obtained multiple run sequences are embedded into the HEVC compression domain, so that copyright protection can be carried out on HEVC video contents. Moreover, the coefficient block obtained in the I-frame coding process is used for obtaining the video code stream containing the watermark, intra-frame error propagation is eliminated, watermark information embedding is conveniently and rapidly achieved, the watermark information embedding flexibility is improved, and the subsequent watermark information extraction process can be simplified.

Description

technical field [0001] The present invention relates to the field of video coding and computer technology, in particular, to a HEVC-based video watermarking method and device. Background technique [0002] With the advent of the era of multimedia information explosion, the related problems are gradually exposed, especially the problem of information security is becoming more and more prominent. [0003] Currently, piracy of videos, games, movies, music, and software causes economic losses of hundreds of billions of dollars every year. While piracy causes economic losses, it also seriously hits the enthusiasm of creators, which has a negative impact on the healthy development of the market. At the same time, with the help of a variety of multimedia information editing software, pirates can make lossless copies of the original digital products and spread them through the Internet. Even, in order to achieve some purposes, all kinds of tampering and forgery can be carried out ...
