Embodiment Construction

[0039] As known to those skilled in the art, the streaming media includes video streaming media and audio streaming media. This embodiment mainly takes video streaming media as an example to describe the method for embedding digital watermarks in the present invention in detail.

[0040]As mentioned above, the video streaming media is transmitted to the client through the video server and network, and played by the streaming media player of the client. The content of described video stream media is made up of a large amount of frames, and the standard format of video stream media is shown in conjunction with Fig. 1 and Fig. 2, and its frame comprises main frame and differential frame, and described main frame refers to picture in video file Each pixel on the frame has a frame represented by data, which shows the basic image and serves as a reference image for the subsequent difference frame, that is, a single main frame is a complete picture; and the difference frame record is ...

Abstract

A method for embedding digital watermark of stream media includes selecting at least one key position requiring to embed digital watermark from frame of video stream media, simulating said watermark to be video frame of video stream media being embedded on selected key position, transmitting video stream media with embedded watermark to client end through network mode, collecting various information from client end by client end according to content and contained command of digital watermark and feeding collected various information back to relevant central server.

Description

technical field [0001] The invention relates to the technical field of streaming media processing, more specifically, to a method for embedding watermark information in streaming media. Background technique [0002] In recent years, with the advancement of digital technology and the rapid development of the Internet, the exchange of multimedia information has reached an unprecedented depth and breadth, and its content and form have become more abundant. At present, information and entertainment services integrating text, audio and video have become the mainstream, and the main body with content has become "streaming media (Streaming media)" instead of web pages. [0003] Streaming media technology refers to the use of streaming transmission to divide multimedia information (text, pictures, sound, video and other files, as well as real-time audio / video sources) into individual packets through various compression methods, and the video server according to specific Sequentiall...
