Abstract:
Devices and methods for power management during media playback are provided. For example, an electronic device according to an embodiment may include storage, a decoder, an output buffer, and data processing circuitry. The storage may store compressed media data that may be decoded by the decoder. The output buffer may store the decoded media data before the decoded media data is played out. The data processing circuitry configured may measure a fullness of the output buffer and may set an operating frequency of the storage, the decoder, the output buffer, or the data processing circuitry, or a combination thereof, depending on a format of the compressed media data and the fullness of the output buffer.
