Abstract

Data packets which in addition to useful information, contain an item of information concerning the temporal sequence thereof, are transmitted from a first data network to a second data network. The reading out of the buffered data is initiated at a predeterminable location that is independent of the storage segmentation that results from the storage of data packets and is thus particularly suited for efficiently transmitting RTP data packets.

an output module transmitting the data to the second data network;

a synchronization module;

a memory device temporarily storing the data packets based on the time sequence; and

a read apparatus reading the data packets which have been temporarily stored, starting with a predetermined data packet at a starting point located at any desired point in a data packet.

19. The system as claimed in claim 18, wherein said synchronization module adds a predetermined delay time to a time ranking of the data to control output of the data by said output module.

20. The system as claimed in claim 19, wherein said memory device includes

a header information memory storing header information for the data packets based on sequence numbering of the data packets;
