Systems and methods for responding to electrical-power loss in a DJ media player

A method for responding to DJ media-player electrical-power loss, the method comprising:

• storing enough electrical charge on one or more energy-storing devices within a DJ media player to at least finish audio playback of a currently-playing media on the DJ media player and perform a shutdown procedure in an event of a disruption in electrical current or potential supplied by a power source of the DJ media player, wherein the electrical charge is stored based on a playback time remaining in the currently-playing media, wherein the one or more energy-storing devices maintain a voltage level that is lower than a normal operating voltage for the DJ media player;
• sensing the disruption in the electrical current or the potential supplied by the power source to the DJ media player;
• continuing the audio playback of the currently-playing media after sensing the disruption;
• presenting on a DJ media-player display a notification comprising a certain amount of time within which the shutdown procedure will be initiated;
• and
• initiating the shutdown procedure upon sensing that a voltage supplied to the DJ media player has changed from the normal operating voltage.

A DJ media player comprising:

• a display to show audio playback information;
• one or more energy-storing devices for maintaining a voltage level that is lower than a normal operating voltage for the DJ media player;
• a processor configured for responding to DJ media-player electrical-power loss, wherein responding to the DJ media-player electrical-power loss comprises:
• storing enough electrical charge on the one or more energy-storing devices to at least finish audio playback of a currently-playing media on the DJ media player and perform a shutdown procedure in an event of a disruption in electrical current or potential supplied by a power source of the DJ media player, wherein the electrical charge is stored based on a playback time remaining in the currently-playing media;
• sensing the disruption in the electrical current or the potential supplied by the power source to the DJ media player;
• powering the DJ media player using the electrical charge on the one or more energy-storing devices;
• continuing the audio playback of the currently-playing media after sensing the disruption;
• determining a rate at which voltage is dropping;
• presenting on the display a notification comprising one of a certain amount of time within which the shutdown procedure will occur or a timer indicating an amount of time until the shutdown procedure begins;
• and
• initiating the shutdown procedure upon sensing that a voltage supplied to the DJ media player has changed from the normal operating voltage.
