Data transmitter, especially for OSI/SO 7-layer model data security layer, has time marker allocation unit that allocates generated time marker to current data packet or data packet to be generated

摘要

The device has interfaces to the data transmission layer and higher layers of the data communications reference model, a unit for generating isochronous data packets, a time marker generating unit for generating a time marker per isochronous data packet controlled by an external control signal (AVSync) and a time marker allocation unit that allocates the generated time marker to the currently existing data packet or a data packet to be generated.
