Patents by Inventor Matthew Aubrey Watson

Matthew Aubrey Watson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Audio coding system using spectral hole filling
    Patent number: 7447631
    Abstract: Audio coding processes like quantization can cause spectral components of an encoded audio signal to be set to zero, creating spectral holes in the signal. These spectral holes can degrade the perceived quality of audio signals that are reproduced by audio coding systems. An improved decoder avoids or reduces the degradation by filling the spectral holes with synthesized spectral components. An improved encoder may also be used to realize further improvements in the decoder.
    Type: Grant
    Filed: June 17, 2002
    Date of Patent: November 4, 2008
    Assignee: Dolby Laboratories Licensing Corporation

  • Modulating one or more parameters of an audio or video perceptual coding system in response to supplemental information
    Patent number: 7395211
    Abstract: A method of modifying the operation of the encoder function and/or the decoder function of a perceptual coding system in accordance with supplemental information, such as a watermark, so that the supplemental information may be detectable in the output of the decoder function. One or more parameters are modulated in the encoder function and/or the decoder function in response to the supplemental information.
