Abstract
The invention provides a protocol and a method for a plurality of separate devices to stream audio and/or video in a synchronized manner in a computer network. One device is session leader and controls synchronization of the streaming of the other devices. If the session leader device is switched off, or becomes otherwise unavailable, local election algorithms on the other devices serve to automatically elect a new session leader to synchronize to in an autonomous manner, e.g. based on a random number election based algorithm. In this manner, a self-organizing synchronization network is provided.
