Adaptive Transporting System Of Network Video With Embedded Watermark

As video data is easily modified by attacker and intruder during video communication process,which makes identification of modification on video data the key content by many researchers. As video watermarking technology is using data hiding technology that embed specific information into the video data in order to take effect on copyright protection, secret communications,authentication,and realization of product logo and so on, application of digital video watermarking on multimedia authentication is considered in this passage,and multimedia authentication detection is realized by setting up adaptive watermarking system.In this paper, Gstreamer/Farsight framework is used to build an adaptive system for video communication with embedded watermark. This system can transmitte watermark while transmitting video data as watermark is embedded into the video data,and also the system can control the sending rate of encoded video data and the amount of watermark to control the quality of the video according to packets loss rate,round-trip time of data packets to complete adaptive feedback control. The system aims to strengthen the robustness of watermark transmission with the basis of assuring the correctness of video transmission and quality of video communication. Moreover,a scheme on how to integrate audio/video framework and communication protocols into instand communication system is brought up,and reasonable explaination and analysis on cases is brought up to provide effective theoretical and practical reference to scientific effort on related realization of audio/video communication system.The system solution can complete correctly transmitting video watermark under 1% packets loss rate, and have high robustness.
