Abstract: A transmission system includes multiple network elements for the transmission of a plurality of data units from at least one network element having a data source, to at least one further network element that has a data sink and a data buffer. Transmission systems of this kind are used for the composition of news items in a news broadcast studio or for the remote transmission of video sequences. Very strict requirements are then imposed on the data transmission, notably as regards the temporal control of the data transmission, in order to achieve real-time, interference-free data output via the data sink. Therefore, means is provided for temporal control of the data transmission from the data source to the data buffer, and for the temporal control, independently of the former, of the data transmission from the data buffer (11) to the data sink.
