Abstract: After the calling of the playback action of the first resource, the control device calls a multiple resource prefetch action including a plurality of prefetch resource identifiers for a plurality of prefetch resources. The media renderer prefetches the plurality of prefetch resources from the media server on the basis of the plurality of prefetch resource identifiers. The control device calls a playback action of a second resource corresponding to one of the plurality of prefetch resources. The media renderer provides seamless transition between the first resource and the second resource.
