Abstract:
Disclosed wireless systems, devices, and methods can leverage existing hardware for BLE communications to provide a low-latency streaming (LLS) link suitable for supporting CROS and BiCROS features in hearing aids. An illustrative embodiment of a low-latency audio streaming method includes: (a) sending intermittent packets of digital audio data as a wireless signal; and (b) for each intermittent packet: (A) listening for a responsive packet; and (B) sending the digital audio data in a retransmitted packet only if no responsive packet is detected. Any retransmitted packet that is sent follows the corresponding intermittent packet with a delay no greater than a length of two interframe spacing (IFS) intervals separated by a responsive packet. An illustrative embodiment of a low-latency audio streaming device includes a transmit chain and a receive chain. The transmit chain periodically transmits intermittent packets of digital audio data as a wireless signal. The receive chain operates to detect a responsive packet to each intermittent packet. The transmit chain retransmits a packet of digital audio data each time the receive chain fails to detect a responsive packet, ensuring a delay no greater than a length of two IFS intervals separated by a responsive packet.

Claim (Index 19):
A wireless system that comprises:\n a first hearing aid for a first ear, the first hearing aid including:\n a microphone to capture and digitize an input audio signal into digital audio data; and \n a first wireless transceiver that operates to send a wireless signal having intermittent packets of the digital audio data, to receive a responsive packet beginning one interframe spacing (IFS) interval after each intermittent packet, and, if a responsive packet is missed, to resend the digital audio data in a retransmission packet beginning one IFS interval after an expected completion of the responsive packet that is missed; and \n a second hearing aid for a second ear, the second hearing aid including:\n a second wireless transceiver that operates to receive said intermittent packets, to send a responsive packet beginning one IFS interval after each intermittent packet that is received, and, if an intermittent packet is missed, to receive a retransmission packet beginning one IFS interval after an expected completion of a responsive packet; and \n an output transducer that produces an output audio signal based at least in part on the digital audio data in said intermittent packets or said retransmission packets.
