Latest Patents
Nuijten's latest patents include innovative methods for embedding supplemental data in encoded signals, such as audio and video. One of his notable inventions is a method of embedding watermarks in a signal encoded by an encoder with a feedback loop, such as a sigma-delta modulator. This method involves embedding a digital watermark pattern in the signal by modifying selected samples of the encoded signal. The circuit for modifying these samples is located within the encoder's feedback loop, ensuring that the watermarking effect is compensated in subsequent encoding steps, thus maintaining a high signal-to-noise ratio. Another significant patent involves a sigma-delta modulator that features a plural order loop filter. This modulator consists of a series of first-order integrating sections, each with its own integrator and limiter. The design allows for stability across varying input signal levels by activating limiters in a specific order as the input signal increases.
