PROBLEM TO BE SOLVED: To provide a signal recording and reproducing apparatus whereby a user searches its desired reproduction position and reproduces it from a recorded video signal and/or audio signal. SOLUTION: In the case of recording a video signal and/or audio signal, a feature vector generating section 20 of the signal recording and reproducing apparatus 1 generates a characteristic vector characterizing the video signal and/or audio signal, and also records the feature vector to a recording section 10. In the case of reproducing the recorded video signal and/or audio signal, a registration section 40 registers the characteristic vector or the like in the vicinity of a position designated by a user as a book mark. When the user designates any of the book marks, a matching detection section 60 searches a matching position on the basis of the feature vector of the book mark and the recorded feature vector, and a reproduction section 20 starts reproducing the video signal and/or audio signal at the reproduction position set by a reproduction position decision section 70 on the basis of the matching position.
