  • Patent number: 8145246
    Abstract: A system includes a transmitting device, an intermediate communications device, and a receiving device. The system establishes a first synchronous wireless link between a transmitting device and the intermediate device, and a second synchronous wireless link between the intermediate device and the receiving device. The transmitting device may include a wireless audio transmitter, a sampling unit configured to convert an incoming audio signal to a stream of digitized audio samples, an encoder unit configured to code the stream of digitized audio samples according to an audio codec based on a sample oriented audio compression algorithm to provide a stream of coded digitized audio samples, and a signal transmitting unit transmitting the stream of coded digitized audio samples over the first synchronous wireless link to the intermediate device. The intermediate device transmits the stream of coded digitized audio samples to the receiving device through the second synchronous wireless link.

  • Publication number: 20100067723
    Abstract: A body worn communications device for communicating with a head-worn listening device, the communications device being adapted for receiving a multitude of audio signals and for transmitting at least one audio signal selected among the multitude of audio signals to the listening device, the communications device having a number of functional push-buttons for influencing the selection and properties of said audio signals. The communications device has a user interface having a number of functional push-buttons for influencing the state of the user interface, such as the selection (and de-selection) of an audio signal, events and properties related to the audio signal, and wherein the state of the user interface is indicated at the same button where the state can be influenced.

  • Publication number: 20090298431
    Abstract: The invention relates to a method of transmitting audio data between a transmitter and a receiver. The invention further relates to a listening system. The object of the present invention is to provide a scheme for creating a low latency audio transmission link. This is achieved in that the method comprises in the transmitter: a) sampling an incoming audio signal to provide a stream of digitized audio samples; b) coding the stream of audio samples according to an audio codec providing a stream of coded samples; c) transmitting the stream of coded samples over a synchronous wireless transmission link; in the receiver: d) receiving the stream of coded samples; e) decoding the stream of coded samples according to said audio codec to a stream of digitized audio samples. Advantages of the present invention include a minimization of transmission delay while maintaining a relatively high audio quality. The invention may e.g. be used for wireless audio transmission from an audio source to a listening device, e.g.
