WIRELESS SOUND TRANSMISSION SYSTEM AND METHOD
First Claim
1. A system for providing sound to at least one user, comprising:
- at least one audio signal source for providing audio signals;
a transmission unit comprising a digital transmitter for applying a digital modulation scheme in order to transmit the audio signals as data packets from the audio signal source via a wireless digital audio link;
at least one receiver unit for reception of audio signals from the transmission unit via the digital audio link, comprising at least one digital receiver;
means for stimulating the hearing of at least one user according to audio signals supplied from the receiver unit;
wherein the transmission unit is adapted to transmit each data packet in a separate slot of a TDMA frame at a different frequency according to a frequency hopping sequence,wherein, in at least some of the slots, the audio signals are to be transmitted as audio data packets, wherein a same audio packet is to be transmitted at least twice in a same TDMA frame, without expecting acknowledgement messages from the at least one receiver unit, andwherein the TDMA frames are structured for unidirectional broadcast transmission of the audio data packets, without individually addressing the at least one receiver unit.

Abstract
A system for providing sound to at least one user, having at least one audio signal source for providing audio signals; a transmission unit with a digital transmitter for wirelessly transmitting the audio signals as data packets; at least one receiver unit with at least one digital receiver for reception of the audio signals from the transmission unit; a mechanism for stimulating the hearing of the user(s) according to audio signals supplied from the receiver unit. The transmission unit transmits each data packet in a separate slot of a TDMA frame at a different frequency in a frequency hopping sequence, in at least some of the slots, the audio signals are transmitted as audio data packets, the same audio packet being transmitted at least twice in the same TDMA frame without expecting acknowledgement, and the TDMA frames being structured for unidirectional broadcast transmission of the audio data packets.

27. A method for providing sound to at least one user, comprising the steps of:
-
providing audio signals from at least one audio signal source to a transmission unit comprising a digital transmitter for applying a digital modulation scheme; transmitting audio signals via a digital wireless audio link from the transmission unit to at least one receiver unit comprising at least one digital receiver; stimulating the hearing of the at least one user according to audio signals supplied from the receiver unit; wherein each data packet is transmitted in a separate slot of a TDMA frame at a different frequency according to a frequency hopping sequence, wherein, in at least some of the slots, the audio signals are transmitted as audio data packets, wherein a same audio packet is transmitted at least twice in a same TDMA frame, without expecting acknowledgement messages from the at least one receiver unit, and wherein the TDMA frames unidirectionally broadcast transmission of the audio data packets, without individually addressing the at least one receiver unit.
