Abstract
A method and a device for transmitting a transport stream according to a digital television-transmission standard for stationary and/or mobile receivers with program and service data for a national and a regional broadcast determines the transmission capacity in the transport stream provided in each case for the national and the regional broadcast through a first multiplexer within a centrally positioned headend. The first multiplexer then fills the transport stream with program and service data for national broadcast within the transmission capacity of the transport stream provided for the broadcast and marks the transmission capacity provided within the transport stream for the regional broadcast. Second multiplexers provided in the regional headends and/or in the regional transmitters in each case fill the marked transmission capacity of the transport stream, transmitted in each case from the central headend to several regionally positioned headends and/or regionally positioned transmitters, with program and service data for regional broadcast.
