Patent ID: 8214064

Claim:
A handheld portable audio device suitable for reproducing MPEG encoded audio data, the handheld portable audio device comprising: a plurality of inputs, including a forward input, a reverse input, a random input, and a play control input; one or more memory chips to store multiple selections of compressed digitized audio data; a display; an audio output; one or more processors to reproduce the multiple selections of compressed digitized audio data in an audible format and to provide information to the display; a re-chargeable battery; an output receptive to headphones; wherein the multiple selections of compressed digitized audio data are compressed according to a Moving Pictures Expert Group (MPEG) compression standard; wherein, when a selection of compressed digitized audio data is being reproduced, the display provides the selection's title; wherein, when the selection of compressed digitized audio data is being reproduced selection of the forward input for a first amount of time will cause the one or more processors to reproduce another selection of compressed digitized audio data; wherein, when the selection of compressed digitized audio data is being reproduced, selection of the reverse input for a second amount of time will cause the one or more processors to begin reproducing the selection of compressed digitized audio data from its beginning; wherein, when the selection of compressed digitized audio data is being reproduced, selection of the play control input will cause the one or more processors to stop reproducing the selection of compressed digitized audio data; wherein, when no selection of compressed digitized audio data is being reproduced, selection of the play control input will cause the one or more processors to begin playing the selection of compressed digitized audio data; wherein, when the power level of the re-chargeable battery falls below a selected level, the display provides an indication relating to the power level; wherein in response to selection of the random input, the one or more processors reproduces the multiple selections of compressed digitized audio data in a random order; and wherein the selection of the reverse input occurs after the selection of the random input occurs.
