Abstract
At least one multimedia presentation is selected by a user of a first device, accessed from a storage source, and presented to the user. Simultaneously, information is transmitted to at least a second device to cause the selected multimedia presentation to be presented by the at least second device without the at least second device receiving input from a second user. Continuous media streams from the first user may be captured and transmitted to the second device. The presenting of the multimedia presentation on the first device is coordinated with the presenting of the multimedia presentation on the second device. The presenting of the captured media streams on the second device is coordinated with the capturing of those streams and the presenting of the multimedia presentation on the second device. Users may individually control the multimedia presentations and the captured media streams.
