Amazon patents TV remote that helps pick the clearest audio channel

This patent describes a system where a TV remote measures wireless interference at its own location, which is often closer to your ears than the TV. The TV uses these readings to choose the best frequency for sending audio to your headphones, ensuring a more stable connection.

Why it mattersIt could reduce audio dropouts in wireless headphones by using the remote as a better sensor for signal quality.

In the filing’s own words

A media playback system may include features for mitigating interference. The media playback system may include a display device such as a smart TV that wirelessly transmits audio data to one or more listening devices such as earbuds, headphones, etc. The media playback system may include a remote control that can communicate using the same or similar frequencies and/or channels used for transmitting audio data. The media playback system may therefore use the radio(s) of the remote control to measure interference as a position removed from the smart TV and potentially closer to the listening device. This measurement may better reflect the listening device's ability to receive data packets reliably than a measurement of interference taken only at the location of the smart TV.

What exactly they claim (claim 1)

1. A method comprising: receiving, by a media device, a first request for media content; receiving, by the media device from a remote-control device, first data including at least a first value representing a first measurement of interference corresponding to a first wireless communication channel and a second value representing a second measurement of interference corresponding to a second wireless communication channel; determining, based on at least the first data, to send audio data via the first wireless communication channel; and based on the determining to send audio data via the first wireless communication channel, sending first audio data corresponding to the media content via the first wireless communication channel.
