摘要:
数字媒体文件的复制与传输越来越方便,使得数字媒体版权保护面临空前挑战,而数字视频作为最主要的一种媒体形式,如何对大量的数字视频进行保护成为迫切需要解决的问题。 数字版权保护包括数字水印、加密等关键技术。 通过调用 FFMPEG 的解码库和 SDL 显示,在解码后的 YUV 像素数据的基础上实现视频、图片的水印叠加,重点研究视频水印系统的模块化设计。 从系统功能需求出发,利用模块化的设计思想,将水印系统分为输入模块、处理模块和输出模块,为不同编码格式的视频水印算法提供一个通用的仿真平台。 针对视频水印系统的高实时性要求,实现接收、解码、水印叠加及显示叠加后的 YUV 数据,提高视频水印的实时性,为视频的版权保护提供一种方法。
Abstract:
The replication and transmission of digital media files is more and more convenient,which makes the digital media copyright protection under unprecedented challenges. The digital video as the main form of media,how to protect a large number of digital video is an urgent problem to be solved. The key technologies of digital copyright protection include digital watermarking and encryption and so on. Through the use of decodes of FFMPEG and SDL display,the watermark overlay of video and picture is implemented based on the decoded YUV pixel data. We focus on the modular design of video watermarking system. Starting from the requirements of system function,the watermarking system is divided into input module,processing module and output module. A common simulation platform is provided for the video watermarking algorithm for different encoding formats. For the high real-time requirements of the video watermarking system,the receiving,decoding,watermarking overlay and the display of the YUV data are implemented,which can improve the real time of video watermarking and provide a method for the copyright protection of video.
