Device and method for analyzing an information signal

For analyzing with the information unit block sequence intelligent signal; the block sequence of continuous block is block sequences' fingerprint sequences, indicated the information moulding, for (12) continuous the fingerprint identifying result, the identifying result expression of the information block unit is connected with the first information entity. Then, a continuous fingerprint's identifying result, and (14) at least two hypotheses, the first set is a block sequence with the supposition of the first information entity is connected, the second set of the block sequence with the supposition of the second information entity is connected. Then, and a to inspect (16) to obtain a hook result to multiple, hypotheses (20) made based on detection results with the statement of intelligent signal. With realising intelligent signal meaningful and reliability of continuous analysis.
