Abstract

A system comprising a media player configured to play media content, a projector operatively coupled to the media player, and a control unit operatively coupled to the media player and the projector is provided. The control unit is configured to detect an on-screen display condition associated with the media player, and the control unit is configured to prevent first information associated with the on-screen display condition and provided by the media player from being displayed by the projector in response to detecting the on-screen display condition.

Claims

1. A system comprising:

a media player configured to play media content from a disc;

a projector operatively coupled to the media player; and

a control unit operatively coupled to the media player and the projector;

wherein the control unit is configured;

a) to detect an on-screen display condition associated with the media player while the media player is playing the media content,

b) to prevent first on-screen display information associated with the on-screen display condition and provided by the media player from being displayed by the projector while the media player is playing the media content in response to detecting the on-screen display condition and in response to the disc being a digital video disc (DVD),

c) to cause second on-screen display information from the control unit to be displayed by the projector in place of the first on-screen display information while the media player is playing the media content in response to detecting the on-screen display condition and in response to the disc being the DVD,

d) to allow the first on-screen display information to be displayed by the projector while the media player is playing the media content in response to detecting the on-screen display condition and in response to the disc not being the DVD, and wherein the first and second on-screen display information does not include content from the disc.

2. The system of claim 1 wherein the on-screen display condition comprises a user input from an integrated control device.

3. The system of claim 1 wherein the on-screen display condition comprises a user input from a remote control device.

4. The system of claim 1 wherein the on-screen display condition comprises a state of the media player.

5. The system of claim 1 further comprising:

a source selection unit operatively coupled to the media player, the projector, and the control unit;

wherein the control unit is configured to cause the source selection unit to prevent the first on-screen display information associated with the on-screen display condition and provided by the media player from being displayed by the projector in response to detecting the on-screen display condition and in response to the disc being the DVD.

6. The system of claim 5 wherein the control unit is configured to cause the source selection unit to provide the second on-screen display information to the projector in place of the first on-screen display information while the media player is playing the media content in response to detecting the on-screen display condition and in response to the disc being the DVD.

7. The system of claim 6 wherein the control unit is configured to provide the second on-screen display information to the source selection unit.

8. The system of claim 7 wherein the projector comprises a digital micromirror device (DMD).

9. The system of claim 7 wherein the projector comprises a liquid crystal display (LCD) device.

10. The system of claim 1 wherein the media content is stored on the disc.

11. The system of claim 1 further comprising:

a speaker operatively coupled to the media player.

12. The system of claim 1 further comprising:

an input/output unit operatively coupled to the control unit;

wherein the input/output unit is configured to receive a signal from a remote control device.

13. A method performed by a control unit of a media projector system including a projector and a media player, the method comprising:

detecting an on-screen display condition associated with the media player while the media player is playing media content from a disc;

preventing first on-screen display information associated with the on-screen display condition and provided by the media player from being displayed by the projector while the media player is playing the media content in response to detecting the on-screen display condition and in response to the disc being a digital video disc (DVD);

causing second on-screen display information from the control unit to be displayed by the projector in place of the first on-screen display information while the media player is playing the media content in response to detecting the on-screen display condition and in response to the disc being the DVD;

allowing the first on-screen display information to be displayed by the projector while the media player is playing the media content in response to detecting the on-screen display condition and in response to the disc not being the DVD, and wherein the first and second on-screen display information does not include content from the disc.

14. The method of claim 13 further comprising:

determining whether the disc in the media player comprises the DVD; and

detecting the on-screen display condition associated with the media player subsequent to determining that the disc in the media player comprises the DVD.

15. The method of claim 14 further comprising:

determining whether a disc play state has been detected;

providing a signal to the media player to cause the disc to be played in response to determining that the disc play state has been detected; and

determining whether the disc in the media player comprises the DVD subsequent to determining that the disc play state has been detected.

16. The method of claim 13 wherein preventing the first on-screen display information associated with the on-screen display condition and provided by the media player from being displayed by the projector includes causing the first on-screen display information not to be provided to the projector.

17. The method of claim 13 further comprising:

providing a signal associated with the on-screen display condition to the media player.

18. The method of claim 13 wherein the first on-screen display information comprises a splash screen.

19. The method of claim 13 wherein the first on-screen display information comprises a symbol.

20. A system including a media player configured to play a disc and a projector operatively coupled to the media player, the system comprising:

means for detecting an on-screen display condition associated with the media player while the media player is playing media content from the disc;

means for preventing first on-screen display information associated with the on-screen display condition and provided by the media player from being displayed by the projector while the media player is playing the media content in response to detecting the on-screen display condition and in response to the disc being a digital video disc (DVD);

means for causing second on-screen display information from the control unit to be displayed by the projector in place of the first on-screen display information while the media player is playing the media content in response to detecting the on-screen display condition and in response to the disc being the DVD;

means for allowing the first on-screen display information to be displayed by the projector while the media player is playing the media content in response to detecting the on-screen display condition and in response to the disc not being the DVD, and wherein the first and second on-screen display information does not include content from the disc.

21. The system of claim 20 further comprising:

means for determining whether a disc in the media player comprises the DVD.

22. The system of claim 20 further comprising:

means for detecting a user input associated with the on-screen display condition.

23. The system of claim 20 further comprising:

means for detecting a signal from the media player associated with the on-screen display condition.
