摘要： A data communication system for communicating one or more payload streamed data signals and an auxiliary data signal, the auxiliary data signal being organised as one or more data packets according to a data packet protocol, each packet having a packet destination address, comprises:

at least two data handling nodes, a transmitting one of the data handling nodes being arranged to transmit data to a receiving one of the data handling nodes;
means associated with the transmitting node for formatting the packets of the auxiliary data signal into a streamed data signal format and for multiplexing the payload streamed data signals and the formatted auxiliary data signal into a bitstream for transmission;
means associated with the receiving node for demultiplexing the input streamed data signals and the formatted auxiliary data signal and for reformatting the auxiliary data signal into packets according to the data packet protocol.

摘要： A data communications system for communicating a data signal formed of successive data elements, the system comprising a transmission node; a reception node; and a link providing a data connection from the transmission node to the reception node; in which:

the transmission node comprises means for transmitting a synchronisation clocking signal to the reception node via the link, the synchronisation clocking signal having synchronising features occurring at a frequency lower than a data element rate; means for assembling elements of the data signal into data frames, each data frame having a plurality of successive data elements of the data signal, for transmission to the reception node via the link, the assembling means being responsive to the synchronisation clocking signal so as to set a synchronisation flag associated with a data element having a first predetermined temporal relationship with a synchronising feature of the synchronisation clocking signal; and the reception node comprises: means for detecting a synchronising feature of the synchronisation clocking signal received from the transmission node; means for disassembling received data frames to regenerate the data signal, the disassembling means being operable to detect a data element associated with a set synchronisation flag; means for outputting a data element associated with a set synchronisation flag at a second predetermined temporal relationship with respect to the synchronising feature of the received synchronisation clocking signal; the first and second predetermined temporal relationships being arranged so that a predetermined system latency exists between input of a data element to the transmission node and subsequent output of that data element by the reception node.
