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 the terminal 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 method for constructing a digital mark in streaming media monitoring, a method for verifying a digital mark and a streaming media monitoring system, 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 monitoring the stream. Media data constructs a system that hides information and verifies it. Background technique [0002] Television is one of the most important communication media at present, and it is also the media that can most affect corporate image and consumer behavior. According to relevant surveys, there are currently nearly 400 TV stations in China, carrying 2,000 sets of program production and broadcasting. TV reaches more than 1 billion people. The popularization of TV and the development of market economy have also greatly promoted the development of the TV advertising industry. At presen...
