  • Publication number: 20030179782
    Abstract: Data transmission apparatus for multiplexing one or more channel data streams of equal, predetermined, data rate into a transmission data stream comprises: means for generating a control data stream of the same data rate as the channel data rate, in which first periodically repeating portions of the control data stream provide a synchronisation signal and second periodically repeating portions of the control data stream provide identification data specifying information about the channel data streams with reference to a predetermined ordering of the channel data streams; and means for multiplexing the control data stream with the one or more channel data streams in a cyclic pattern of equally-sized data portions so that a data portion from the control data stream is followed by data portions from each of the channel data streams according to the predetermined ordering of channel data streams.

  • Publication number: 20030152241
    Abstract: Audio processing apparatus comprises one or more touch-sensitive controls for adjusting a gain applied to an audio processing channel in response to movement of a user's hand while touching the controls; a detector for detecting a predetermined sequence of activation of a touch sensitive control by the user; and a signal switch responsive to a detection of the predetermined sequence of activations to toggle between a first mode of operation in which the audio processing channel is operable to suppress an input audio signal and a second mode of operation in which the input audio signal is not suppressed.

  • Patent number: 6604009
    Abstract: A signal processor for 1-bit signals comprises a fifth order Delta-Sigma Modulator (DSM) having an input for receiving a 1-bit signal and an output at which a processed 1-bit signal is produced by a quantizer. The quantizer receives a p-bit signal from a series of five signal integration stages. Each stage comprises a first 1-bit multiplier coupled to the input, a second 1-bit multiplier coupled to the output, an adder which sums the outputs of the coefficient multipliers and an integrator which integrates the output of the adder. A final stage comprises a coefficient multiplier and an adder. The adder sums the output of the coefficient multiplier and the output of the integrator of the preceding integration stage. The coefficients are chosen to provide an overall attenuation of the input signal and of the quantization noise produced by the quantizer. Reduction of quantization noise allows several DSMs to be connected in series by preventing the build-up of excess noise, which may compromise stability.

  • Patent number: 6583801
    Abstract: An array of user-operable controls and a proximity sensing apparatus are contained in an apparatus wherein the proximity sensing apparatus detects whether a user's hand is within a predetermined distance from the controls. Once the user's hand is a predetermined distance from the controls, a display screen displays screen icons associated with its respective control. The screen icons are controlled by a display processor which responsive to the user's hand being within a predetermined distance from the controls, alters the screen icon associated with its respective control.

  • Patent number: 6577910
    Abstract: A digital audio signal processor processes digital audio signals having a first sampling rate S1. The processor has a multiplicity of manually adjustable controls (403) for setting desired parameters of signals to be processed. Sampling means (404) sample each control (403) setting at a second sampling rate S2 less than the first rate S1 to determine the settings thereof. Applying means (401) responsive to the sampling means apply the sampled settings to the signals. For each control the applying means determines the difference of successive samples of setting and applies to the signal, subject to control by that control, increments of setting each increment being a predetermined fraction 1/n of the said difference at a rate nS2 which is n times the said second sampling rate S2.
