  • Patent number: 9774980
    Abstract: An audio processor acquires processed sound data, which is obtained by processing original sound data according to a content of processing defined such that first sound is emitted under the standard sound emission condition, in association with a sound emission device, acquires a control signal, and acquires a device sound emission condition. In order to make second sound emitted by the sound emission device under the acquired device sound emission condition close to the first sound, the audio processor identifies the correction content of the processed sound data based on a difference between the device sound emission condition and the standard sound emission condition, the control signal, and the processed sound data acquired in association with the sound emission device. The audio processor corrects the processed sound data according to the correction content, and supplies the corrected processed sound data to the sound emission device.

  • Patent number: 8004609
    Abstract: There is provided an amplifier that measures a display delay time caused until a video is displayed actually after a video signal is generated, and sets automatically a delay time of an audio signal such that an audio synchronizes with this display. Test video data is stored in a memory 11. This test video data is video data that generates a clear change in luminance in such a manner that a screen is changed suddenly from deep black to pure white. This test video is output to a video display device 2 such as PDP, for example, and a delay time generated until the test video is displayed actually after this test video is output is measured. Since the luminance of the screen is changed suddenly when the test video is displayed actually, this change can be sensed by an optical sensor 20. The audio signal is delayed by setting this delay time in an audio signal processing portion 13, so that the video can synchronize with the audio.
