Abstract

Ein Übertragungsverfahren für mehrere einzelne Datenströme (31, 32, ..., 3i-1, 3i, 3i+1, ..., 3N) mit Echtzeitanforderung in einem gemeinsamen Datenstrom (TSout) über ein digitales Rundfunk-Übertragungssystem bei optimaler Ausnutzung der vorhandenen Datenübertragungsrate umfasst folgende Verfahrensschritte:
• Ermitteln des Bedarfs an Übertragungskapazität für jeden einzelnen Datenstrom (31, 32, ..., 3i-1, 31, 3i+1, ..., 3N) in jedem zyklisch aufeinander folgenden Zeitintervall mit jeweils konstanter vorbestimmter Zyklusdauer (tZYKLUS),
• Summation der Bedarfe an Übertragungskapazität im jeweiligen Zeitintervall und Ermittlung einer kleinst möglichen gemeinsamen Datenübertragungsrate für den gemeinsamen Datenstrom (TSout) im jeweiligen Zeitintervall aus der Division des je Zeitintervall summierten Bedarfs an Übertragungskapazität durch die Zyklusdauer (tZYKLUS) des Zeitintervalls,
• Zuweisung der Differenz an Datenübertragungsrate zwischen der im jeweiligen Zeitintervall ermittelten gemeinsamen kleinst möglichen Datenübertragungsrate und der vorhandenen Datenübertragungsrate an eine derartige Anzahl zusätzlicher einzelner Datenströme (3i+1, ..., 3N), dass bei minimaler ungenutzter Datenübertragungsrate deren summierte Bedarfe an Übertragungskapazität im jeweiligen Zeitintervall mit der Differenz an Datenübertragungsrate übertragbar sind.

A transmission method for a plurality of individual data streams (3 1 , 3 2 , ..., 3 i-1 , 3 i , 3 i + 1 , ..., 3 N ) with a real-time request in a common data stream (TS out ) via a digital Broadcast transmission system with optimal utilization of the existing data transmission rate comprises the following method steps:
• Determining the need for transmission capacity for each individual data stream (3 1 , 3 2 , ..., 3 i-1 , 3 1 , 3 i + 1 , ..., 3 N ) in each cyclically consecutive time interval, each with a constant predetermined cycle duration (t CYCLE ),
Summation of the transmission capacity requirements in the respective time interval and determination of the lowest possible common data transmission rate for the common data stream (TS out ) in the respective time interval from the division of the total time requirement of transmission capacity by the cycle time (t CYCLUS ) of the time interval;
• Assignment of the difference in data transmission rate between the common minimum possible data transmission rate determined in the respective time interval and the existing data transmission rate to such a number of additional individual data streams (3 i + 1 ,..., 3 N ) that with minimum unused data transmission rate their summed requirements Transmission capacity in the respective time interval with the difference in data transmission rate can be transmitted.
