FireWire”

computer cable in such a manner that said computer readable data is capable of transferring to said computer system through said “

FireWire”

computer cable.

6. The portable DVD player system, as recited in claim 2, wherein said computer connecting means comprises a “

FireWire”

computer connector electrically connected to said computer converting means for connecting with said computer system through a “

FireWire”

computer cable in such a manner that said computer readable data is capable of transferring to said computer system through said “

FireWire”

computer cable.

7. The portable DVD player system, as recited in claim 2, wherein said video output means comprises a video encoder electrically connected to said data decoder to encode said video data into a video signal through a filtering circuit wherein said video signal is capable of transferring to said video/audio system through a video cable.

8. The portable DVD player system, as recited in claim 4, wherein said video output means comprises a video encoder electrically connected to said data decoder to encode said video data into a video signal through a filtering circuit wherein said video signal is capable of transferring to said video/audio system through a video cable.

9. The portable DVD player system, as recited in claim 6, wherein said video output means comprises a video encoder electrically connected to said data decoder to encode said video data into a video signal through a filtering circuit wherein said video signal is capable of transferring to said video/audio system through a video cable.

10. The portable DVD player system, as recited in claim 2, wherein said audio output means comprises an audio DAC electrically connected to said data decoder to convert said audio data into an audio signal through a filter and amplify circuit, wherein said audio signal is capable of transferring to said video/audio system through an audio cable.

11. The portable DVD player system, as recited in claim 8, wherein said audio output means comprises an audio DAC electrically connected to said data decoder to convert said audio data into an audio signal through a filter and amplify circuit, wherein said audio signal is capable of transferring to said video/audio system through an audio cable.
