Abstract

A method, system, and article of manufacture that allows amateur camera operators to share video and audio with other amateur camera operators at the same event over a cooperative, ad hoc network. One embodiment of the present invention comprises forming an ad hoc network comprising a plurality of recording devices, and communicating audiovisual signals between the plurality of recording devices in the ad hoc network. In some embodiments, this method may further comprise transmitting a replay request to the plurality of recording devices and receiving an audiovisual signal corresponding to the replay request, transmitting a push request to the plurality of recording devices, and/or transmitting a message to at least one of the plurality of recording devices.

Claims

1-20. -20. (canceled)

21. A camera, comprising:

an audiovisual recording device that generates a primary audiovisual signal;

a wireless network interface coupled to the audiovisual recording device and adapted to communicate the primary audiovisual signal to a plurality of other audiovisual recording devices over an ad hoc network, the wireless network interface further adapted to receive a secondary audiovisual signal and a descriptor packet associated with the secondary audiovisual signal from another recording device in the ad hoc network;

wherein the descriptor packet describes the content of the secondary audiovisual signal and wherein the descriptor packet includes recording device location information to enable complimentary angle selection; and

a processor adapted select a preferred secondary audiovisual signal based on the contents of the descriptor packet; and

a storage medium that simultaneously records the primary audiovisual signal and the selected secondary audiovisual signal.

22. The camera of claim 21, further comprising a peer-to-peer network manager coupled to the wireless network interface, wherein the peer-to-peer network manager cooperates with the wireless network interface to communicate with the ad hoc network of audiovisual recording devices.

23. The camera of claim 21, wherein the audiovisual recording device comprises a charge-coupled device array.

24. The camera of claim 21, wherein the audiovisual signal comprises a video signal and an audio signal.
