ABSTRACT:
The invention is concerned with a method to control and manage the status of a battery of a portable multimedia device equipped with means to memorize digital data representing audio and video sequences, with means to process the sequences and with a display screen of the video sequences. The process comprises the steps of downloading an audiovisual data flow in the means of memorization; evaluating of the energy available in the battery; and selecting either first processing of the memorized data that needs only a part of the energy available in the battery, so as to conserve a pre-determined quantity of energy, or second processing of the memorized data that needs all the available energy.
