Abstract

Herein described is a system and method of directly storing and retrieving data using a multimedia recording device. The method comprises storing multimedia data into a data storage device without using processor memory associated with said multimedia recording device. The method comprises retrieving the multimedia data from the data storage device without using processor memory associated with said multimedia recording device. The system comprises a multimedia recording device for receiving the multimedia data and a data storage device for storing the multimedia data. The multimedia data is written into and read from the data storage device without using processor memory associated with the multimedia recording device.

Claims

1. A method of storing data into a multimedia recording device comprising:

receiving said data by said multimedia recording device; and

transmitting said data directly into a data storage device of said multimedia recording device without storing said data into a memory used as a data buffer by a processor of said multimedia recording device.

2. The method of claim 1 wherein said multimedia recording device comprises a digital video recorder (DVD).

3. The method of claim 1 wherein said data storage device comprises a hard disk drive.

4. The method of claim 1 wherein said data storage device comprises an optical reader/writer.

5. The method of claim 4 wherein said optical reader/writer comprises a DVD reader/writer.

6. The method of claim 1 wherein said memory comprises a random access memory.

7. A method of playing data from a data storage drive of a multimedia recording device comprising:

reading said data from said data storage device of said multimedia recording device; and

transmitting said data directly to a decoder of said multimedia recording device without storing said data into a memory used as a data buffer by a processor of said multimedia recording device, said decoder used to provide decoded data to a display.

8. The method of claim 7 wherein said multimedia recording device comprises a digital video recorder (DVD).

9. The method of claim 7 wherein said data storage device comprises a hard disk drive.

10. The method of claim 7 wherein said data storage device comprises an optical reader/writer.

11. The method of claim 10 wherein said optical reader/writer comprises a DVD reader/writer.

12. The method of claim 7 wherein said memory comprises a random access memory.

13. A method of storing data from one or more multimedia recording capable devices into a data storage device comprising:

receiving said data by said one or more multimedia recording capable devices; and

transmitting said data into said data storage device by way of connecting said data storage device to said one or more multimedia recording capable devices by way of using a bypass interface provided by said data storage device, said transmitting performed without using a processor memory of said one or more multimedia recording capable devices, said processor memory used as a data buffer for said data.

14. The method of claim 13 wherein said one or more multimedia recording capable devices comprises one or more DVR capable devices.

15. The method of claim 13 wherein said data storage device comprises a hard disk drive.

16. The method of claim 13 wherein said data storage device comprises an optical reader/writer.

17. The method of claim 13 wherein said one or more multimedia recording capable devices comprise one or more video camcorders.

18. The method of claim 13 wherein said bypass interface provides 802.3x transmission.

19. The method of claim 13 wherein said bypass interface provides 802.11 x or Bluetooth transmission.

20. The method of claim 13 wherein said bypass interface comprises one or more IEEE 1394 compliant connectors.

21. The method of claim 13 wherein said bypass interface comprises one or more USB compliant connectors.

22. The method of claim 13 wherein said bypass interface comprises one or more serial and/or parallel type of connectors.

23. A method of playing data from a data storage device to one or more multimedia recording capable devices comprising:

reading said data from said data storage device; and

transmitting said data to one or more decoders of said one or more multimedia recording capable devices by way of using a bypass interface provided by said data storage device, said transmitting performed without using a processor memory of said one or more multimedia recording capable devices, said processor memory used as a data buffer for said data, said decoder used to provide decoded data to a display.

24. The method of claim 23 wherein said one or more multimedia recording capable devices comprises one or more DVR capable devices.

25. The method of claim 23 wherein said data storage device comprises a hard disk drive.

26. The method of claim 23 wherein said data storage device comprises an optical reader/writer.

27. The method of claim 23 wherein said one or more multimedia recording devices comprises one or more video camcorders.

28. The method of claim 23 wherein said bypass interface provides 802.3x transmission.

29. The method of claim 23 wherein said bypass interface provides 802.11x or Bluetooth transmission.

30. The method of claim 23 wherein said bypass interface comprises one or more IEEE 1394 compliant connectors.

31. The method of claim 23 wherein said bypass interface comprises one or more USB compliant connectors.

32. The method of claim 23 wherein said bypass interface comprises one or more serial and/or parallel type of connectors.

33. A multimedia recording and playback system comprising:

a multimedia recording device used for receiving multimedia data;

a data storage device for storing and retrieving said multimedia data, said storing and said retrieving performed without using a processor memory of said multimedia recording device, wherein said processor memory is used as a buffer for said multimedia data.

34. The multimedia recording and playback system of claim 33 wherein said multimedia recording device comprises one or more serial buses used for directly transmitting said multimedia data between said multimedia recording device and said data storage device.

35. The multimedia recording and playback system of claim 33 wherein said multimedia recording device comprises said data storage device.

36. The multimedia recording and playback system of claim 33 wherein said data storage device transmits and receives said multimedia data and one or more command/control signals by way of a bypass interface.

37. The multimedia recording and playback system of claim 36 wherein said bypass interface provides 802.3x transmission

38. The multimedia recording and playback system of claim 36 wherein said bypass interface provides 802.11x or Bluetooth transmission.

39. The multimedia recording and playback system of claim 36 wherein said bypass interface comprises one or more serial and/or parallel type of connectors.
