摘要
Example techniques involve pre-caching media content. An example implementation involves a first playback device detecting, via at least one proximity sensor, motion in proximity to the proximity sensor. In response, the first playback device sends, to a second playback device, one or more first messages indicating that the first playback device detected motion. Afterwards, the first playback device receives, via the network interface from the second playback device in response to the one or more first messages, one or more second messages that instruct the first playback device to pre-cache, from a network source, a portion of audio content indicated in a playback queue associated with a playback device group including the first playback device and the second playback device. The first playback device receives a command to play back the playback queue and plays back the audio content indicated in the playback queue jointly with the second playback device.
