<p>The purpose of the present invention is to provide a technique whereby the playback of an AV source such as audio data can be continued with as little power consumption as possible after the stopping of a power source such as an engine. A vehicle-mounted device (1) is provided with a first playback unit (71) for playing back a first AV source, second playback units (72-75) for playing back a second AV source different from the first AV source with the power consumption needed for playback being lower than that of the first playback unit (71), an engine operation detection unit (26) for detecting whether an engine (2) is stopped, and a controller (11). The controller (11) performs playback switching which includes stopping playback of the first AV source and starting playback of the second AV source when stoppage of the engine (2) is detected by the engine operation detection unit (26) during playback of the first AV source.</p> |
