Latest Patents
One of his latest patents is titled "Transmission system implementing different coding principles." This invention involves a transmission system for the encoded transmission of audio signals with frequency band compression. In this system, an input signal is divided into two spectral portions in a coder. One portion is digitally encoded by a time-domain coder, while the other is coded by a transform domain coder. The two digitally coded signals are multiplexed for transmission as a composite digitally coded signal to a receiver. At the receiver, the composite signal is demultiplexed, and the two spectral portions are decoded by their respective decoders. The decoded signals are then combined to reconstitute the originally transmitted audio signal.
Another significant patent by De Bont is "Transmission system with simplified source coding." This invention describes an audio signal digital transmission system where the signal is sampled, and successive segments of N samples are digitally encoded. The encoding process, previously done by vector quantization, is improved by comparing the envelope of a signal segment with a limited number of reference envelopes. The best matching reference envelope is selected, and an identifying codeword is transmitted along with related parameters. The receiver then reproduces the signal from the reference envelope and the related parameters, achieving a considerable reduction in memory capacity and calculation complexity.
