摘要:
The invention first of all does not relate to a precise data rate analysis of informational signal sections to be transferred in a subsequent transfer cycle per time multiplex. Instead, according to the invention, estimated values for relative wait times (Delta-T) are transferred in a current transfer cycle from the current time slot to the next time slot of the same service, based on estimated values for the subsequent data rates that are as precise as possible. In the following transfer cycle, actual data rates can be set that can deviate from the estimated data rates for the individual informational signals, whereby forecasted time slot limits for the following transfer cycle can shift. Said possible shifting of the time slot limits is subject to several ancillary conditions, however. No time slot of the following transfer cycle can begin before the estimated start time that is signaled. At constant data rates, estimated time slot structure and actual time slot structure are identical, so that in this case the concept according to the invention maximizes the advantages and efficiency of time-slicing.
摘要:
The invention relates to a device for demultiplexing a packet-based transport stream (14) of transport stream packets (12), which are each provided with a systematic forward error detection code, wherein the transport stream packets are each assigned to a data sink (20) of a plurality of data sinks (20), such that a data stream (36) of data packets (38) protected by means of a forward error detection code, which data stream is addressed to a particular data sink (20), is embedded into a useful data section of the transport stream packets that are assigned to the same data sink (20), wherein the device is designed to determine a probability value for each of the plurality of data sinks for a predetermined transport stream packet (12) that is erroneous according to the systematic forward error detection code, which probability value specifies the probability that the predetermined transport stream packet (12) is associated with the respective data sink (20), and to associate the predetermined transport stream packet to a selected data sink of the plurality of data sinks on the basis of the probability values for the plurality of data sinks.
