Wireless Sound Tranmission System and Method
First Claim
1. A method for providing sound, the method comprising:
- receiving audio signals;
converting the audio signals into audio data;
transmitting the audio data via a digital wireless link from a transmission unit to a receiver unit;
synchronizing the receiver unit and the transmitting unit to form a wireless network comprising the transmission unit and the receiver unit as synchronized network members;
providing sound to a user based at least partially on the audio data received at the receiver unit,wherein the audio data is transmitted as audio data packets in separate slots of a frame structure,wherein the frame structure comprises a listening slot during which at least one of the synchronized network members listens; and
transmitting control data from an external control device to the receiver unit in a control data block based on a sequence pattern,wherein the sequence pattern is based at least partially on a duration and periodicity of the listening slot, andwherein the external control device is not a synchronized network member.

Abstract
A method for providing sound to at least one user, in which audio signals are captured and transformed into audio data that is transmitted to at least one receiver unit; audio signals are generated from the received audio data and the hearing of the user(s) stimulated thereby; wherein the audio data is transmitted as audio data packets in separate slots of a TDMA frame structure, wherein the transmission unit and the receiver unit(s) are synchronized to form a wireless network, wherein each TDMA frame structure has at least one listening slot during which the synchronized network members do not transmit data and at least one network members listens, and wherein control data is transmitted from an external control device according to a sequence pattern selected according to the duration and periodicity of the listening slot(s) to be received by the at least one synchronized network member during said listening slot(s).
