Digital marking structure and verifying method in stream medium monitoring and broadcasting

Abstract

The invention relates to a method for constructing digital marks of data-flow monitoring broadcast media and a method for verifying the digital marks and a system for monitoring broadcast media. The system includes: a signal acquisition unit which is used for automatically tuning, searching and locking the streaming media data, a marking media unit which is used for constructing different detecting marks for the data-flow from the signal acquisition unit to adapt to different monitoring broadcast tasks and mark them in the streaming media data files, a monitoring unit which is deployed in theterminal broadcasting network nodes or the backbone network nodes according to their different functions to monitor the marks contained in the streaming media data, a category storing unit which is used for correcting, classifying and storing the codes output by the marking media unit and real-time detecting result by the monitoring unit, and a analyzing device which is used for statistical analysis, alarm and printing with a friendly interface.

Description

technical field [0001] The invention relates to a digital mark construction method, a digital mark verification method and a streaming media monitoring system in streaming media monitoring and broadcasting, in particular to a method for constructing hidden information for video / audio streaming media, a method for verifying the constructed hidden information, and a method capable of convection Media data constructs a system that hides information and performs verification. Background technique [0002] Television is currently one of the most important communication media, and it is also the media that can most influence corporate image and consumption behavior. Relevant surveys show that there are currently nearly 400 TV stations in China, carrying 2,000 sets of programs for the production and broadcast, which are watched every day. More than a billion people on TV. The popularization of TV and the development of the market economy have also greatly promoted the development ...

Problems solved by technology

[0004] Similar problems also exist in the broadcasting process of movie copies, that is, movie copy piracy. At present, the spread and proliferation of pirated copies on the Internet is the most serious and the most harmful, which seriously affects the implementation of intellectual property protection and copyright protection.

At present, there is no ideal technology to prevent this kind of piracy, but the protection scheme of hidden technology is used to pre-store tracking information in the movie copy, relying on the imperceptibility and robustness of hidden technology to realize the monitoring and tracking of copy piracy, It must be a reasonable and effective film copy monitoring technology
