A software method for synchronizing the output of data communications across several output devices, despite geographical distance and/or latency, allowing for the data stream to be dynamically-altered in real time and providing for instant and seamless echoing of local input. Media selections for play back may be chosen in real-time by any number of operators and combined in real-time to create a meta-media effect of synchronistic and coherent real-time collaboration. Operator input causes signal transfers to be sent to remote computer(s), which causes each computer to play transition frames, with the amount played depending on the latency from the source so that all finish simultaneously. The result is synchronous display to a distributed audience of a media stream that anyone can affect in real-time. This system enables mass-scale collaboration for highly complex systems such as online virtual reality applications, and for less complex phenomena such as radio and television.
