Abstract
Disclosed herein, among other things, are systems and methods for synchronizing audio and video signals for a listening system. One aspect of the present subject matter includes a method including receiving an audio signal and a video signal from an external device. The audio signal is processed and transmitted to a hearing assistance device having a wearer. In various embodiments, the video signal is transmitted to a video display using a delay such that the audio signal and the video signal are synchronized for the wearer.

(canceled)
A system, comprising:
- a listening device;
- and
- a synchronization device, including:
- a wireless input configured to receive an audio signal and a video signal from an audio/video source;
- a bi-directional wireless communication link to the listening device;
- a processor configured to process the audio signal and convert the audio signal into a wireless signal and transmit the wireless signal to the listening device using the bi-directional wireless communication link;
- and
- a wireless output configured to transmit the video signal to a video display using a delay based on a wireless signal delay calculated using a received acknowledgement from the listening device, such that the wireless signal and the video signal are synchronized for the listening device, and configured to transmit the audio signal to the video display using the delay to synchronize the audio signal and video signal to the display.

A method, comprising:
- receiving, using a synchronization device, an audio signal and a video signal from an audio/video source;
- processing, using the synchronization device, the audio signal and converting the audio signal into a wireless signal, and transmitting the wireless signal to a listening device using a time stamp;
- and
- transmitting, using the synchronization device, the video signal to a video display using a delay based on a wireless signal delay calculated by synchronizing clocks between the synchronization device and the listening device and using the time stamp, such that the wireless signal and the video signal are synchronized for the listening device;
- and
- transmitting, using the synchronization device, the audio signal to the video display using the delay to synchronize the audio signal and video signal to the display.
