Abstract: The present invention concerns a router for providing isochronous data transfer and asynchronous data transfer on the basis of a predetermined protocol between devices of different network sections connected to the router, when a connection management application executed by the router translates a user request to transfer data from a transmitting device of a first network section to a receiving device of a second network section into commands of the protocol for establishing a first data connection between the transmitting device and the router and a second data connection between the router and the receiving device when the data is transferred from the transmitting device via the established data connections to the receiving device.

Abstract: The present invention relates to a digital multimedia network 1 with latency control comprising apparatuses for processing of data streams, wherein a borderline input apparatus providing a data stream generates a latency time stamp (LTS) which contains an absolute time indicating a creation time of said data stream and an accumulated delay time which is updated by each apparatus processing said data stream, wherein said latency time stamp (LTS) of said data stream is evaluated by a borderline output apparatus of said network which synchronizes said data stream.

Abstract: An apparatus for modifying a command message (CMD) received from a source apparatus to control a target device parameter of a target apparatus within a digital multimedia network, wherein a hierarchical parameter address (HPA) or a parameter value contained in said command message (CMD) is changed according to at least one change script to provide a modified command message (CMD').
