A system for generating digital postage stamps wherein a PC requests digital postage stamps from a data center. It is proposed that the guide mechanism be oriented so that in its straw depositing position it deflects downward a portion of the second crop stream oriented in the direction of the first crop stream being ejected, and in its chopping position it does not significantly deflect the flow of the two crop streams. The centralized station forms a composite signal of all the video signals multicasts the composite signal to the local videoconference terminals over satellite that can be received by hundreds, thousands or more recipients.
