Abstract

Some demonstrative embodiments include devices, systems and/or methods of switching between frequency channels in wireless communication. An apparatus may include, for example, a wireless video source module capable of automatically switching from performing wireless video communication with a first wireless video destination module to performing wireless video communication with a second wireless video destination module. Other embodiments are described and claimed.

Claims

1. An apparatus comprising:

a wireless video source module capable of automatically switching from performing wireless video communication with a first wireless video destination module to performing wireless video communication with a second wireless video destination module.

2. The apparatus of claim 1, wherein said wireless video source module is capable of:

releasing a wireless video communication link between said wireless video source module and said first wireless video destination module; and

establishing a wireless video communication link between said wireless video source module and said second wireless video destination module.

3. The apparatus of claim 1, wherein said wireless video source module is capable of communicating with said second wireless video destination module via the same communication channel for communicating between said wireless video source module and said first wireless video destination module.

4. The apparatus of claim 1, wherein said wireless video source module is capable of communicating with said second wireless video destination module via a first communication channel different from a second a communication channel for communicating between said wireless video source module and said first wireless video destination module.

5. The apparatus of claim 1, wherein said wireless video source module comprises:

a video source to generate video signals of a video image; and

a wireless video transmitter to transmit a wireless video transmission representing said video signals.

6. The apparatus of claim 5, wherein said video source comprises at least one of a set-top-box, a digital-versatile-disc, a digital-video-recorder, a game console, a personal computer, a portable computer, a personal-digital-assistant, a video-cassette-recorder, a video camera, a cellular phone, a video player, an MP-4 player, and a video dongle.

7. An apparatus comprising:

a video destination module capable of automatically switching from performing wireless video communication with a first wireless video source module to performing wireless video communication with a second wireless video source module.

8. The apparatus of claim 7, wherein said video destination module is capable of:

releasing a wireless video communication link between said wireless video destination module and said first wireless video source module; and

establishing a wireless video communication link between said wireless video destination module and said second wireless video source module.

9. The apparatus of claim 8, wherein said video destination module is capable of detecting whether or not said second wireless video source module is in communication with one or more other wireless video communication modules via an existing communication link.

10. The apparatus of claim 9, wherein said video destination module is capable of joining said existing communication link.

11. The apparatus of claim 9, wherein said video destination module is capable of establishing a new communication link for communicating with said second wireless video source module.

12. The apparatus of claim 7, wherein said wireless video destination module comprises:

a wireless video receiver to receive a wireless video transmission representing video signals of a video image; and

a video destination to process said video signals.

13. The apparatus of claim 12, wherein said video destination comprises at least one of a display, a television, a projector, a monitor, an audio/video receiver, and a video dongle.

14. A method of communicating between a plurality of wireless video communication modules, the method comprising:

automatically switching a wireless video source module from performing wireless video communication with a first wireless video destination module to performing wireless video communication with a second wireless video destination module.

15. The method of claim 14, wherein said switching comprises:

releasing a wireless video communication link between said wireless video source module and said first wireless video destination module; and

establishing a wireless video communication link between said wireless video source module and said second wireless video destination module.

16. The method of claim 14, wherein said switching comprises communicating between said wireless video source module and said second wireless video destination module via the same communication channel for communicating between said wireless video source module and said first wireless video destination module.

17. The method of claim 14, wherein said switching comprises communicating between said wireless video source module and said second wireless video destination module via a first communication channel different from a second a communication channel for communicating between said wireless video source module and said first wireless video destination module.

18. The method of claim 14, wherein a distance between said wireless video source module and each of said first and second wireless video destination modules is no more than one hundred meters.

19. The method of claim 18, wherein said distance is no more than twenty-five meters.

20. A method of communicating between a plurality of wireless video communication modules, the method comprising:

automatically switching a wireless video destination module from performing wireless video communication with a first wireless video source module to performing wireless video communication with a second wireless video source module.

21. The method of claim 20, wherein said switching comprises:

releasing a wireless video communication link between said wireless video destination module and said first wireless video source module; and

establishing a wireless video communication link between said wireless video destination module and said second wireless video source module.

22. The method of claim 21, wherein establishing the wireless communication link comprises detecting whether or not said second wireless video source module is in communication with one or more other wireless video communication modules via an existing communication link.

23. The method of claim 22, wherein establishing said link comprises joining said existing communication link.

24. The method of claim 22, wherein establishing said link comprises establishing a new communication link.

25. The method of claim 20, wherein a distance between said wireless video destination module and each of said first and second wireless video source modules is no more than one hundred meters.

26. The method of claim 25, wherein said distance is no more than twenty-five meters.
