Abstract

A digital video system integrates onto a single circuit board the features of a hard disk drive with DVR control functionality. The video system includes a front end module that receives and tunes incoming video signals, a DVR module that provides overall system control and DVR trick play functionality and a storage control module that controls storage and retrieval of video content to a mass storage device such as a hard disk drive. In one embodiment, the front end module, the DVR module and storage control module are integrated on a single printed circuit board.

Claims

1. A digital video system comprising:

a digital video recorder (DVR) module that controls storage, retrieval and display of video content; and

a storage control module that manages the storage and retrieval of the video content to and from a mass storage device under control of the DVR module;

wherein the DVR module and the storage control module are integrated onto a single circuit board.

2. The video system of claim 1, wherein the mass storage device is a hard drive assembly.

3. The video system of claim 1, further including a front end module that extracts the video content from incoming video signals.

4. The video system of claim 3, wherein the video signals comprise at least one of conventional terrestrial analog broadcast, terrestrial digital, satellite, cable video signals or digital video content received via the internet.

5. The video system of claim 1, wherein the DVR module further provides DVR trick play functionality.

6. The video system of claim 5, wherein the DVR trick play functionality includes at least one of fast forward, fast reverse, slow forward, slow reverse, pause/resume and instant replay.

7. The video system of claim 1, wherein the DVR module and the hard disk module are connected on the single circuit board using a circuit board trace.

8. The video system of claim 1, wherein the DVR module further controls playback of the stored video content.

9. The video system of claim 1, wherein the DVR module further receives and responds to user commands relating to playback of the stored video content.

10. The video system of claim 1, further comprising at least one of a High-Definition Multi-media Interface (HDMI), a Universal Serial Bus connector, a SCART connector and a modem interface.

11. The video system of claim 1, further comprising at least one of composite video, s-video, component video and Left/Right audio outputs.

12. The video system of claim 1, further comprising at least one of SPDIF (Sony/Philips Digital Interface), a SmartCard interface, an infrared (IR) sensor, an RS-232 serial port, an Inter-Integrated Circuit Bus (I²C), Reset, Fan or programmable general purpose input/output (GPIO).

14. The video system of claim 12, wherein the mass storage device is a hard drive assembly.

15. The video system of claim 12, wherein the mass storage device is one of an optical disk, a magneto-optical disk, a solid state memory or a video random access memory.

13. A digital video system comprising:

a digital video recorder (DVR) controller that controls storage, retrieval and display of video content;

a storage controller that manages the storage and retrieval of the video content to and from a mass storage device under control of the DVR controller; and

a single circuit board that interconnects the DVR controller and the storage controller.

16. A digital video system comprising:

a digital video recorder (DVR) controller that controls storage, retrieval and display of selected video content;

a storage controller that manages the storage and retrieval of the selected video content to and from a mass storage device under control of the DVR module; and

a single power control circuit that generates, monitors and controls power supplied to the DVR controller and the storage controller.

17. The digital video system of claim 16, further including a single circuit board that interconnects the DVR controller, the storage controller and the single power control circuit.

18. A digital video system comprising:

a digital video recorder (DVR) controller that controls storage, retrieval and display of selected video content; and

a storage control controller that manages the storage and retrieval of the selected video content to and from a mass storage device under control of the DVR controller;

wherein information is communicated between the DVR controller and the storage controller without forwarding the information between multiple circuit boards.

19. The digital video system of claim 18, wherein the DVR controller and the storage controller are integrated onto a single circuit board.

20. A digital video system comprising:

a digital video recorder (DVR) controller that controls storage, retrieval and display of video content; and

a storage controller that manages the storage and retrieval of the video content to and from a mass storage device under control of the DVR module;

wherein the DVR controller and the storage controller are integrated onto a single circuit board.

21. The video system of claim 20, wherein the mass storage device is a hard drive assembly.

22. The video system of claim 20, further including a front end that extracts the video content from incoming video signals.

23. The video system of claim 22, wherein the video signals comprise at least one of conventional terrestrial analog broadcast, terrestrial digital, satellite, cable video signals or digital video content received via the internet.

24. The video system of claim 22 wherein the front end extracts the video content from the incoming video signals in response to user commands relating to selection of desired video content.

25. The video system of claim 20, wherein the DVR controller further controls playback of the stored video content.

26. The video system of claim 20, wherein the DVR controller further receives and responds to user commands relating to storage and playback of the video content.

27. The video system of claim 20, further comprising a single power control circuit that generates, monitors and controls power supplied to the DVR controller and the storage controller.

28. A digital video system comprising:

a digital video recorder (DVR) controller that controls storage, retrieval and display of video content; and

a storage controller that manages the storage and retrieval of the video content to and from a mass storage device under control of the DVR module;

wherein the DVR controller and the storage controller are integrated onto a single circuit board and are not connected by an external cable.

29. The video system of claim 28, wherein the mass storage device is a hard drive assembly.

30. A video system comprising one hardware board integrally housing a digital video recorder (DVR) module, a storage control module and a front end module.
