Abstract

The invention relates to a server side of a stream media visible watermark real-time embedding system, comprising: a video collecting module for real-time collection of video data; a video decoding module for compressive coding of the video data; a watermark embedding module for embedding information of the digital watermark into a code stream output after the video decoding module compresses and codes the video data in order to acquire the video data comprising the watermark; a stream media processing module for storing the video data comprising the watermark and output by the watermark embedding module and transferring the video data in accordance with a connection request from a client side. The invention also comprises a corresponding client and a stream media visible watermark real-time embedding system composed by the server side and the client side. The embodiment of the inventive stream media visible watermark real-time embedding system integrates the digital watermark with coding of the video data, which accomplishes real-time embedding for the watermark in the process of transmission of the stream media so as to achieve protection and authentication for copyright of the stream media information in the process of visiting.

Description

technical field [0001] The invention relates to the technical field of streaming media processing, in particular to a streaming media visible watermark real-time embedding system and its server and client. Background technique [0002] In recent years, with the popularity of the Internet, streaming media services have achieved rapid development, and the scope of application has continued to expand. Not only have a series of streaming media service websites represented by YouTube, online conference systems, P2P (Peer to Peer, Point-to-point) Internet TV-on-demand system and other applications are gradually perfected. Moreover, with the further development of network technology and the popularization of various multimedia terminal equipment, the streaming media service will surely get greater development. [0003] With the development of streaming media services, the issue of digital copyright protection of streaming media has become more and more prominent, and has gradually...
