Abstract: Systems and methods for reducing interference between content play and video recording among multiple devices located proximate to each other. Microphones of devices recording video are muted, or content play is interrupted, according to the actions of a majority of nearby devices.

Conversely, if most devices are not recording video, only those devices which are may have their microphones muted. Actions to reduce interference may be taken according to the current behavior of a majority of proximate devices.
