Abstract (en)
[origin: WO2004006224A1] The invention relates to a method for the transmission of audio signals between a transmitter and at least one receiver according to the prioritizing pixel transmission method. The audio signal is initially broken down into a number of spectral fractions. The broken down audio signal is stored in a two-dimensional array with a plurality of fields, frequency and time being the dimensions and amplitude being the value to be registered in the field. Groups are then formed from said individual fields and a priority is assigned to the individual groups, wherein the higher the amplitudes of the group values are and/or the higher the amplitude differences of the values of one group are and/or the closer the groups are to the actual time, the priority of a group will be higher. Finally, the groups are transmitted to the receiver according to their order of priority.
