Abstract: A method can include receiving, at a given node, a continuous stream of input media from a media source. A value can be computed as a function of each of a plurality of data blocks of the continuous stream of input media received by the given node. The method can also include receiving, at the given node, values computed for a plurality of data blocks of the continuous stream received by another node. A set of the received values from the other node can be correlated with a set of the computed values for the given node to determine an offset between the blocks of the continuous stream of input media that are received by the given node and the blocks of the continuous stream of input media that are received by the other node.
