The invention brings forward a digital television advertisement intelligent identification system, and relates to the technical field of digital television advertisement intelligent identification. The system is characterized in that: the system is composed of a television program video server, a storage server, a database server, a television advertisement intelligent identification server, an emergency power supply module and a management mechanism which are connected onto a C/S network. Based on an industrial control computer platform, a high-precision image characteristic value generation algorithm, a self-adaptive sample library matching identification algorithm and a static state picture flow program browsing and positioning technology are provided so that automatic identification and analytical statistics of advertisement played in satellite and wired digital television programs are realized. Firstly, start and end time of certain segment of new advertisement in the programs is confirmed and marked as an identification sample of the advertisement, and image characteristics of the segment of advertisement are automatically extracted by the system. Then subsequent data are automatically identified continuously by using the sample via an intelligent identification engine and stored in the database so that automatic monitoring and playing of the advertisement on the basis of image identification can be realized.
