  • Patent number: 7720235
    Abstract: A signal processing method divides a first signal of two signals to be compared in similarity into smaller regions, selects one of the regions, and calculates the correlation of the selected one with the other second signal. The method finds a time difference, an expansion factor, and a similarity in one region in which the maximum similarity as the square of the correlation is obtained, and performs integration in the position represented by the time difference and the expansion factor of values based on similarities. The method performs similar processing on all the regions, and evaluates similarity by, in a peak where the integrated value of similarities is a maximum, compares its magnitude with a threshold value. The region corresponding to the peak can be extracted.

  • Patent number: 7673320
    Abstract: It is targeted that CMs by e.g., television broadcast be detected automatically, an access site to detailed contents of a specified one of the CMs be acquired automatically, and connection be made automatically to the access site to enable accessing to the detailed information. A broadcasting station 302 sends out airing signals containing CMs. A consumer terminal (303) detects these CMs from the aired signals and connects to an access site information furnishing device (305) based on the airing time and the airing channel of the detected CM to acquire the access site information of the distribution terminal (301) for e.g., an article of commerce owning the detailed information pertinent to the CM. Based on the access site information, the consumer terminal (303) accesses the distribution terminal (301) to acquire the detailed information pertinent to the CM.

  • Patent number: 7502547
    Abstract: This invention is a signal recording/reproducing apparatus (1) for searching for a reproduction position desired by a user from a recorded video signal and/or audio signal and reproducing the signal. The apparatus has a feature vector generating unit (30). When recording a video signal/audio signal, the feature vector generating unit (30) generates a feature vector characterizing the video signal and/or audio signal and also records this feature vector to a recording unit (10). When the recorded video signal/audio signal is reproduced, a registration unit (40) registers feature vectors near a position designated by the user, as bookmarks.

  • Patent number: 7454330
    Abstract: A speech encoding method and apparatus in which an input speech signal is divided in terms of blocks or frames as encoding units and encoded in terms of the encoding units, whereby explosive and fricative consonants can be impeccably reproduced, while there is an attenuation of the occurrence of foreign sounds being generated at a transient portion between voiced (V) and unvoiced (UV) portions, so that the speech with high clarity devoid of “stuffed” feeling may be produced. The encoding apparatus includes a first encoding unit for finding residuals of linear predictive coding (LPC) of an input speech signal for performing harmonic coding and a second encoding unit for encoding the input speech signal by waveform coding. The first encoding unit and the second encoding unit are used for encoding a voiced (V) portion and an unvoiced (UV) portion of the input signal, respectively.

  • Patent number: 7405499
    Abstract: Amplitude, phase and frequency of a sine wave to be generated are calculated on the basis of feature quantity s1 delivered to feature quantity detecting means (2), and are sent to initialization means (3). The initialization means (3) calculates first two points of the sine wave to send the points thus calculated to oscillator (sine wave generating means) (4) as initial value s4. The oscillator (4) sequentially calculates values of respective sample points of waveform by using recurrence formula in accordance with initial value or values instructed from the initialization means (3) to thereby generate a sine wave signal. Thus, sine wave generation is performed without performing modulo-addressing.

  • Publication number: 20080177535
    Abstract: A speaker of encoded speech data recorded in a semiconductor storage device in an IC recorder is to be retrieved easily. An information receiving unit 10 in a speaker retrieval apparatus 1 reads out the encoded speech data recorded in a semiconductor storage device 107 in an IC recorder 100. A speech decoding unit 12 decodes the encoded speech data. A speaker frequency detection unit 13 discriminates the speaker based on a feature of the speech waveform decoded to find the frequency of conversation (frequency of occurrence) of the speaker in a preset time interval. A speaker frequency graph displaying unit 14 displays the speaker frequency on a picture as a two-dimensional graph having time and the frequency as two axes.
