Patents by Inventor Robert Vaughn Jones

Robert Vaughn Jones 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).

  • Method and apparatus for increasing the speed of a full code book search in a quartizer encoder
    Patent number: 6141458
    Abstract: A novel vector quantization encoding system comprises a conventional vector formatter and a novel gross quantizer. The vector formatter generates vectors to be searched in a full code book of vectors. The gross quantizer generates pointers indicative of subsets of vector indices. The vector indices are indicative of groups of vectors to be searched in the full code book that are substantially less in number than the number of vectors in the full code book. A search controller is employed to search only the subset of vectors in the full code book and produce as an output the index of the one vector in the full code book closest to the formatted vector being searched so that the quality of a full code book searched is made faster without degradation of a full code book search.
