A presentation system is disclosed for synchronizing a performance of a plurality of presentation content portions at a network node, wherein, when two such content portions are to be presented concurrently at the network node, at least one is delayed until the other such portion can be presented concurrently therewith. In one embodiment, the content portions are transmitted via at least a portion of the Internet to a plurality of network nodes, wherein the presentation system can distribute the presentation content data to the network nodes via a plurality of network routes and presentation formats. Additionally, the present invention can provide various portions of the content data from a plurality of network server nodes, and during a performance of the presentation, the presentation receiving network nodes can determine a particular variation of the presentation to retrieve from the network server nodes. In particular, the retrieval of presentation data depends upon the transmission characteristics of the network such as data transmission rate. Thus, if a low transmission data rate is detected at a first network node, presentation elements of a reduced size can be retrieved.
