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.

In another example, the portion of the music track may be stored until any user command is received, whether or not the user command causes any changes in the playback mode of the playback device. For instance, in the case that the playback device is already rendering audio content, the approach of the user towards the playback device may be to adjust a playback volume of the audio content. As such, the pre-cached music track may no longer be applicable to why the user approached the playback device once the user command has been received. In a further example, if no user command is received, the portion of the music track may be stored until the playback device, using the one or more sensors, determines that the user is no longer within a vicinity of the playback device. In other examples, the portion of the music track may be stored indefinitely, or for a predetermined duration of time if no user command is received.
