Latest Patents

Y F Dehery holds a patent for a "Subband coded digital transmission system using some composite signals." This innovative system enhances the reproduction accuracy of digital stereo audio signals by transmitting sample data as sub-signals, such as frequency subband signals. In this method, corresponding components, like left and right stereo channels, are combined to transmit only one composite signal per subband. Additionally, an indicator signal is sent to indicate which subbands are combined, along with scale factor signals for all subbands, reflecting the relative intensity of the respective subband signals. The receiver then derives a subband signal for each channel from the composite signal before synthesizing the full channel signals for reproduction.
