Abstract

A device for audio and video playback is operable to receive a digital video signal input or an analog video signal such as a National Television System Committee-standard (NTSC) video signal input through an input connector port of the device. The device may also receive an audio signal input through an audio input connector port. The audio and video playback device includes a storage device for storing audio and video signals in Moving Picture Experts Group-standard (MPEG) format. The audio and video playback device also includes output connector ports operable to provide audio output and video output. A central processing unit in the device receives audio and video input signals from the input connector ports, compresses the audio and video input signals into MPEG format and can store the MPEG-format signals in the storage device. The processor is also operable to retrieve and decompress stored audio and video signals from the storage device and provide output signals to output connector ports.

Claims

1. A device for audio and video playback, comprising:

a first input connector port operable to receive digital video signals;

a second input connector port operable to receive National Television System Committee-standard (NTSC) or PAL video signals;

a third input connector port operable to receive analog audio signals;

a storage device operable to electronically store audio and video signals in a Moving Picture Experts Group-standard (MPEG) format such as MPEG1, MPEG2, and MPEG4;

a first output connector port operable to provide analog video output;

a second output connector port operable to provide analog audio output;

a processor operable to receive input signals from the input connector ports, compress the input signals into MPEG format, store the signals in the storage device, retrieve stored signals from the storage device, and provide output signals to the output connector ports.

2. The device for audio and video playback of claim 1, wherein the digital video signals are input from a personal computer.

3. The device for audio and video playback of claim 2, wherein the digital video signals are input in MPEG format.

4. The device for audio and video playback of claim 1, wherein the device further comprises a Universal Serial Bus (USB) port that operates to provide an interface with a personal computer.

5. The device for audio and video playback of claim 4, wherein the digital video signals are input from a personal computer through the USB interface.

6. The device for audio and video playback of claim 1, wherein the storage device is a disk drive.

7. The device for audio and video playback of claim 1, wherein the first output connector port is connected to a liquid crystal display (LCD).

8. The device for audio and video playback of claim 1, wherein the first output connector port is connected to a digital display.

9. The device for audio and video playback of claim 1, wherein the first output connector port is connected to a NTSC-standard display.

10. A method for audio and video playback, comprising:

providing a first input connector port operable to receive digital video signals;

providing a second input connector port operable to receive NTSC-format video signals;

providing a third input connector port operable to receive audio signals;

providing a storage device operable to electronically store audio and video signals in MPEG format;

providing a first output connector port operable to provide video output;

providing a second video output connector port operable to provide audio output;

providing a processor operable to receive input signals from the input connector ports, compress the signals into MPEG format, store the signals in the storage device, retrieve stored signals from the storage device, and provide output signals to the output connector ports.

11. The method for audio and video playback from claim 10, further comprising:

the processor receiving input signals in MPEG format from the input connector ports and providing output signals to the output connector ports for audio and video playback.

12. The method for audio and video playback from claim 10, further comprising:

the processor receiving compressed audio and video input signals from the input connector ports, decoding the input signals, providing output signals to the output connector ports for audio and video playback, and re-encoding the signals in MPEG-format for storage in the storage device.

13. The method for audio and video playback from claim 10, further comprising:

the processor retrieving audio and video signals stored in the storage device and providing output signals to the output connector ports for audio and video playback.

14. A method for audio and video playback, comprising:

receiving audio and video information at a portable electronic storage device;

storing the audio and video information in a portable electronic storage device;

retrieving the audio and video information from the portable electronic storage device; and

playing the audio and video information from the portable electronic storage device.

15. The method for audio and video playback of claim 14, wherein the audio and video information is received from a personal computer.

16. The method for audio and video playback of claim 15, wherein the audio and video information is received in MPEG format.

17. The method for audio and video playback of claim 14, wherein the audio and video information is stored in a disk drive.

18. The method for audio and video playback of claim 14, wherein the audio and video information is retrieved from a disk drive.

19. The method for audio and video playback of claim 14, wherein the video information is played on an integrated Liquid Crystal Display (LCD).
