Abstract

A system and method for providing group communication services is disclosed. Each of a plurality of group communication devices converts media, such as video, audio, image and/or data into data packets suitable for transmission over a data network, such as the Internet. The data packets are selectively transmitted through the data network to a communications manager. The communications manager acts as a configurable switch, allowing communications from any communication device to be selectively routed to the plurality of communication devices based on the types of the communication devices and/or the requests received from the corresponding users. The communications manager further allows users of other communication systems and devices to participate in group communications with each other.

Claims

1. A method in a communication manager for communicating multimedia among a plurality of communication devices (CDs) operating in a group communication network, the method comprising:

receiving a first media of a first type;

receiving a second media of a second type, the first and second media each being received from one of the plurality of CDs; and

selectively broadcasting the first media, the second media, or both concurrently, to at least one of the plurality of CDs via a half duplex channel based on an expected capability of one or more of the plurality of CDs to play the first and second types of media.

2. The method of claim 1, wherein said first media includes video and said second media includes audio.

3. The method of claim 1, wherein said plurality of communication devices comprise a video camera and a still camera.

4. The method of claim 1, wherein said selectively broadcasting includes selectively broadcasting based on types of the plurality of communication devices.

5. The method of claim 2, wherein said selectively broadcasting includes selectively broadcasting the video at a reduced rate.

6. The method of claim 2, wherein said selectively broadcasting includes selectively broadcasting a still image.

25. The method of claim 1, wherein the first media is of the first type and the second media is of the second type, the first and second types each being different portions of the same media content.

26. The method of claim 1, further comprising:

determining a type of each of the plurality of CDs; and

determining the expected capability of the plurality of CDs at a central server based on the determined types of the plurality of CDs, the central server being remote from the plurality of CDs.

27. The method of claim 1, wherein the first and second media are received from the same CD among the plurality of CDs.

28. The method of claim 1, wherein the first and second media are received from different CDs among the plurality of CDs.

29. The method of claim 1,

wherein the selectively broadcasting step broadcasts both the first media and the second media to a first of the plurality of CDs expected to be capable of playing both the first and second types of media, and

wherein the selectively broadcasting step broadcasts only one of the first media and the second media to a second of the plurality of CDs expected to be capable of playing only one of the first and second types of media.

7. A non-transitory computer-readable medium embodying a set of instructions, wherein the set of instructions when executed by one or more processors comprises:

a set of instructions for receiving a first media of a first type;

a set of instructions for receiving a second media of a second type, the first and second media each being received from one of a plurality of communication devices (CDs); and

a set of instructions for communicating multimedia among the plurality of CDs operating in a group communication network, further selectively broadcasting the first media, the second media, or both concurrently, to at least one of the plurality of CDs via a half duplex channel based on an expected capability of one or more of the plurality of CDs to play the first and second types of media.

8. The non-transitory computer-readable medium of claim 7, wherein said first media includes video and said second media includes audio.

9. The non-transitory computer-readable medium of claim 7, wherein said plurality of communication devices comprise a video camera and a still camera.

10. The non-transitory computer-readable medium of claim 7, wherein said selectively broadcasting includes selectively broadcasting based on types of the plurality of communication devices.

11. The non-transitory computer-readable medium of claim 8, wherein said selectively broadcasting includes selectively broadcasting the video at a reduced rate.

12. The non-transitory computer-readable medium of claim 8, wherein said selectively broadcasting includes selectively broadcasting a still image.

13. An apparatus for communicating multimedia among a plurality of communication devices (CDs) operating in a group communication network, comprising:

means for receiving a first media of a first type;

means for receiving a second media of a second type, the first and second media each being received from one of the plurality of CDs; and

means for selectively broadcasting the first media, the second media, or both concurrently, to at least one of the plurality of CDs via a half duplex channel based on an expected capability of one or more of the plurality of CDs to play the first and second types of media.

14. The apparatus of claim 13, wherein said means for receiving said first media includes means for receiving video and said means for receiving said second media includes means for receiving audio.

15. The apparatus of claim 13, wherein said plurality of communication devices comprise a video camera and a still camera.

16. The apparatus of claim 13, wherein said means for selectively broadcasting includes means for selectively broadcasting based on types of the plurality of communication devices.

17. The apparatus of claim 14, wherein said means for selectively broadcasting includes means for selectively broadcasting the video at a reduced rate.

18. The apparatus of claim 14, wherein said means for selectively broadcasting includes means for selectively broadcasting a still image.

19. A communication manager, comprising:

a receiver capable to receive a first media and a second media of first and second types, respectively, the first and second media each being received from one of a plurality of communication devices (CDs);

a transmitter; and

a processor programmed to communicate multimedia among the plurality of CDs operating in a group communication network capable to selectively broadcast the first media, the second media, or both concurrently, to at least one of the plurality of CDs via a half duplex channel based on an expected capability of one or more of the plurality of CDs to play the first and second types of media.

20. The communication manager of claim 19, wherein said first media includes video and said second media includes audio.

21. The communication manager of claim 19, wherein said plurality of communication devices comprise a video camera and a still camera.

22. The communication manager of claim 19, further capable to selectively broadcast based on types of the plurality of communication devices.

23. The communication manager of claim 20, further capable to selectively broadcast the video at a reduced rate.

24. The communication manager of claim 20, further capable to selectively broadcast a still image.
