Abstract: A method transmits a multiplicity of digital data packets from a transmitter to a receiver arranged in a mobile device. A plurality of data packets in each case is combined to form a block. The multiplicity of data packets are sent out by the transmitter in such a manner that the time intervals between the individual data packets of the respective block vary over the blocks for a plurality of successive blocks, and/or the time duration of the blocks varies for a plurality of successive blocks, and/or the time intervals between the individual data packets in the block vary for a number of blocks. The blocks of data packets are received and decoded by the receiver.

Abstract: A method for synchronizing the reproduction of a digital signal sent by a transmitter to a plurality of mobile audio terminals. The transmitter sends the digital signal as a multiplicity of data packets at a data rate that is constant as an average over time. A signal receiver of each mobile audio terminal receives at least a subset of the multiplicity of data packets and generates a time reference signal. A FIFO signal with information on an occupancy level of a FIFO memory of the mobile audio terminal at specific time points is generated, an instantaneous reproduction speed is set on the basis of the time reference signal and the FIFO signal, the audio reproduction unit reproduces at the instantaneous reproduction speed samples corresponding to the digital signal. The occupancy level of the FIFO memory is thereby kept constant as an average over time.
