Portable sound reproducing system and method
First Claim
1. A portable audio device suitable for reproducing MPEG encoded data, the portable audio device comprising:
- a plurality of inputs, including a forward input, a reverse input, and a play control input;
a data storage to store compressed digitized audio data;
a display;
an audio output;
at least one processor, responsive to selection of at least one of the plurality of inputs, to convert selected compressed digitized audio data stored in the data storage for reproduction by the audio output and to provide information to the display;
a battery; and
wherein, when a first selection of compressed digitized audio data is being reproduced, the display provides the first selection'"'"'s title;
wherein, when a second selection of compressed digitized audio data is being reproduced and in response to selection of the forward input for a first amount of time, the portable audio device advances to another selection of compressed digitized audio data;
wherein, when a third selection of compressed digitized audio data is being reproduced, in response to selection of the reverse input for a second amount of time, the portable audio device begins playing the third selection from a beginning of the third selection of compressed digitized audio data;
wherein, when a fourth selection of compressed digitized audio data is being reproduced, in response to selection of the play control input, the portable audio device stops playing the fourth selection of compressed digitized audio data;
wherein the compressed digitized audio data is compressed according to a Moving Pictures Expert Group (MPEG) compression standard; and
wherein, when the portable audio device is in a selected mode of operation and a voltage of the battery falls below a selected level, the display provides an indication relating to a power level of the battery.
