Abstract

The present invention is directed to a system and method for using a second remote control device for sub-picture control in a television receiver. The present invention may enable two viewers watching independent video contents on a television receiver to independently control their own viewing experience of channel, volume, and the like, with minimal interaction required between the two viewers to coordinate their activities. According to an exemplary aspect of the present invention, a television system may include a television receiver for displaying a main window and a secondary window on a screen of the television receiver. The main window shows first video content, and the secondary window shows second video content. The television system may further include a first remote control device for controlling the first video content and a second remote control device for controlling the second video content. Both remote control devices are communicatively coupled to the television receiver.

Claims

1. A television system, comprising:

a television receiver for displaying a main window and a secondary window on a screen of said television receiver, said main window showing first video content, and said secondary window showing second video content;

a first remote control device, communicatively coupled to said television receiver, for controlling said first video content; and

a second remote control device, communicatively coupled to said television receiver, for controlling said second video content.

2. The television system of claim 1, wherein said screen has an aspect ratio of 16:

9.

3. The television system of claim 1, wherein said second remote control device is substantially different from said first remote control device.

4. The television system of claim 1, wherein said second remote control device is capable of turning said secondary window on and off.

5. The television system of claim 1, wherein said second remote control device is capable of placing said main window and said secondary window in at least one of a picture-in-picture format, a picture-outside-picture format, and his/her format.

6. The television system of claim 1, wherein said second remote control device is capable of moving a location of said secondary window either continuously or among a plurality of pre-determined locations when said secondary window and said main window are in a picture-in-picture or a picture-outside-picture format.

7. The television system of claim 1, wherein said second remote control device is capable of adjusting a size of said secondary window.

8. The television system of claim 7, wherein said size of said secondary window may be increased or decreased in a continuous manner.

9. The television system of claim 7, wherein said size of said secondary window is selected among a plurality of pre-determined sizes.

10. The television system of claim 1, wherein, when a source of said second video content is a television channel, said second remote control device changes said television channel through an up/down button on said second remote control device.

11. The television system of claim 1, wherein, when a source of said second video content is a television channel, said second remote control device changes said television channel through a direct select keypad on said second remote control device.

12. The television system of claim 1, further comprising a headphone, said headphone being communicatively coupled to said television receiver and receiving audio for said second video content.

13. The television system of claim 12, wherein said second remote control device is capable of adjusting a volume level of said audio for said second video content.

14. The television system of claim 12, further comprising a second headphone, said second headphone being communicatively coupled to said television receiver and receiving audio for said first video content.

15. The television system of claim 1, wherein said second remote control device is capable of selecting a video source for said secondary window by selecting among a plurality of available video sources.

16. The television system of claim 1, wherein said second remote control device is capable of selecting an aspect ratio of said secondary window as 4:

3 or 16;

9.

17. The television system of claim 1, wherein said second remote control device uses coded commands different from said first remote control device.

18. The television system of claim 1, wherein said second remote control device sends out a command with a string “

Brand ID+Comm and +Remote ID”

.

19. The television system of claim 1, wherein said Remote ID is a 16-bit format.

20. The television system of claim 1, wherein said Remote ID is assigned at time of manufacture.

21. A method for controlling a secondary window on a screen of a television receiver, said screen having a main window in addition to said secondary window, said main window showing first video content, and said secondary window showing second video content, comprising:

changing said first video content via a first remote control device; and

changing said second video content via a second remote control device.

22. The method of claim 21, further comprising receiving audio for said second video content via a headphone, said headphone being communicatively coupled to said television receiver.

23. The method of claim 22, wherein a volume level of said audio for said second video content is changed via said second remote control device.

24. The method of claim 22, further comprising receiving audio for said first video content via a second headphone, said second headphone being communicatively coupled to said television receiver.

25. The method of claim 24, wherein a volume level of said audio for said first video content is changed via said first remote control device.

26. The method of claim 21, further comprising turning said secondary window on and off via said second remote control device.

27. The method of claim 21, further comprising placing said main window and said secondary window in at least one of a picture-in-picture format, a picture-outside-picture format, and his/her format via said second remote control device.

28.

29. The method of claim 21, further comprising adjusting a size of said secondary window via said second remote control device.

30. The method of claim 29, wherein said size of said secondary window may be increased or decreased in a continuous manner via said second remote control device.

31. The method of claim 29, wherein said size of said secondary window is adjusted among a plurality of pre-determined sizes via said second remote control device.

32. The method of claim 21, wherein, when a source of said second video content is a television channel, said second remote control device changes said television channel through an up/down button on said second remote control device.

33. The method of claim 21, wherein, when a source of said second video content is a television channel, said second remote control device changes said television channel through a direct select keypad on said second remote control device.

34. The method of claim 21, further comprising selecting a video source for said secondary window by selecting among a plurality of available video sources via said second remote control device.

35. The method of claim 34, wherein said video source is a television channel.
