Claim:
1. A method for operating a camera network having a plurality of cameras, comprising: communicating with the plurality of cameras to determine a time base and/or a frame rate for each of the plurality of cameras by facilitating communication with or between each of the plurality of cameras; synchronizing the time base and/or the frame rate for each of the plurality of cameras to the time base and/or the frame rate of one of the plurality of cameras; and coordinating a capture of multimedia data using the plurality of cameras with the synchronized time base and/or frame rate; wherein communicating with the plurality of cameras to determine the time base for each of the plurality of cameras comprises: transmitting at least one communication signal to each of the plurality of cameras; and receiving at least one corresponding response signal from each of the plurality of cameras; wherein synchronizing the time base of the plurality of cameras to the time base of the one of the plurality of cameras comprises: determining at least one transmission time difference for each of the plurality of cameras based on a difference between a transmission time of the communication signal and a receiving time of the corresponding response signal; and adjusting a clock time of each of the plurality of cameras based on the respective at least one determined transmission time difference such that the time base of each of the plurality of cameras is synchronized to the time base of the one of the plurality of cameras.
