Abstract
In a playback apparatus which plays back music in a plurality of audio formats, a control unit detects a voltage level of a power supply unit and restricts a playback of music in one of the audio formats, which requires power consumption whose amount exceeds a given value, when the detected voltage level is lower than a threshold value. Alternatively, the control unit restricts a playback of one of a plurality of pieces of music, which requires power whose amount exceeds a given value, when the detected voltage level is lower than a threshold value.
Claims10
A playback apparatus which plays back music in a plurality of audio formats, the apparatus comprising:
- a voltage level detecting unit configured to detect a voltage level of a battery;
- a control unit configured to restrict a playback of music in one of the plurality of audio formats, which requires power consumption whose amount exceeds a given value, when the voltage level detected by the voltage level detecting unit is lower than a threshold value;
- a first storage unit configured to store first information indicating a correspondence between the plurality of audio formats and power consumption;
- and
- a second storage unit configured to store second information indicating a correspondence between a threshold value of the voltage level and a threshold value of the power consumption,
- wherein the control unit determines an audio format which is to restrict a playback of music using the first information and the second information.
The playback apparatus which plays back music in a plurality of audio formats, the apparatus comprising:
- a voltage level detecting unit configured to detect a voltage level of a battery;
- a control unit configured to restrict a playback of music in one of the plurality of audio formats, which requires power consumption whose amount exceeds a given value, when the voltage level detected by the voltage level detecting unit is lower than a threshold value;
- means for storing first information indicating a correspondence between the plurality of audio formats and power consumption;
- and
- means for storing second information indicating a correspondence between a threshold value of the voltage level and a threshold value of the power consumption,
- wherein the control unit includes means for determining an audio format which is to restrict a playback of music using the first information and the second information.
