  • Patent number: 9565494
    Abstract: The present invention provides an acoustic processing device capable of providing a high-quality sound even in a standby through mode. A controller is characterized by supplying power from an auxiliary power supply to a sound signal processing unit in the standby through mode. In the standby through mode, the controller extracts a sound signal included in an input HDMI signal, outputs a high-frequency sound component from an input/output unit to, for example, a television, and outputs a low-frequency sound component from a sound output terminal to a speaker (for example, a subwoofer) with an amplification function. As a result, the user can listen to content with powerful bass on the television, without operating an amplifying circuit, which consumes most of the power consumed by the acoustic processing device, using a main power supply, that is, while suppressing the power consumption of the acoustic processing device.

  • Patent number: 9445049
    Abstract: Presented herein are techniques for detecting whether a presentation video stream in a conference call includes motion video. In an embodiment, this can be done by detecting the presence of audio. The presence of audio suggests that the presentation video stream may include motion video. If audio is not detected, then the presentation video stream is encoded at a first frame rate. If audio is detected, then the presentation video stream is encoded at a second, higher frame rate to accommodate the motion video. The higher frame rate allows for a better viewing experience by conference participants.

  • Patent number: 9414156
    Abstract: Techniques are described for processing an audio signal to reduce the total harmonic distortion caused when it is reproduced by a loudspeaker, which is located within an audio reproduction device having an enclosure with an associated resonant frequency. After receiving the input audio signal, which includes the resonant frequency of the enclosure, the level of the input audio signal at the resonant frequency is reduced, thereby producing a first processed signal. In addition, the level of said input audio signal is reduced at all frequencies, producing a second processed signal. The first and second processed signals are combined to produce an output audio signal. The degree to which the level of the audio signal at both the resonant frequency and at all frequencies is reduced may be dependent upon the current volume level.

  • Patent number: 8717504
    Abstract: A picture conversion information supply section 130 calculates per frame an affine transformation parameter for picture conversion based on motion information about a moving picture. With reference to a reference picture, a picture conversion section 140 affine-transforms pictures making up the moving picture per frame using the calculated affine transformation parameters. Based on information indicating the center position, angle or scaling factor about the transformed pictures coming from the picture conversion section 140, a sound conversion information calculation section 190 calculates sound conversion information for converting the sound corresponding to the pictures. Based on the sound conversion information, a sound conversion processing section 200 controls the volume of each of the channels making up the sound, adds up the controlled sound of each channel, and outputs the result as output sound to speakers 220.

    Abstract: An audio data spread spectrum embedding and detection method is presented. For each audio frame, a noise sequence is chosen according to the data to be embedded. Then, a spectrum of a chosen noise sequence is shaped by a spectrum of a current audio frame and subtracted from a current frame's spectrum. During detection, a detector is used on a watermarked audio frame to first whiten the watermarked audio frame. Detection scores are then computed against two competing Adaboost learning models. A detected bit is chosen according to the model with a maximum detection score.
