Method for generating digital signature from video signal or tv transmission frame and consecutive pattern recognizing device for broadcasting video segment
专利汇可以提供Method for generating digital signature from video signal or tv transmission frame and consecutive pattern recognizing device for broadcasting video segment专利检索，专利查询，专利分析的服务。并且PURPOSE: To recognize a realtime TV commercial before the end of commercial transmission by allowing the number of total bits from the comparing of frames to express the digital signature of a frame.
CONSTITUTION: In a module 30, a conductor 40 is connected with an A/D converter 50, digitizing each pixel in each frame of a signal to an 8-bit digital language expressing pixel luminance, and the digital language is sorted within a TV frame buffer or a memory 60. The memory 60 is connected to a D/A converter 70 and an original TV signal is reconstituted to be observed on a monitor 80. The monitor confirms the efficiency of a digitizing process and evaluates a processed video output. The TV frame buffer 60 is connected with a digital signal processor 90 and processes each digitized frame with a system software and the other circuits to form digital signatures. These signatures are used for forming a data base, positioned within a system part 34 and a realtime TV signal signature is searched and compared.
