Abstract: To configure a transport data stream, in particular to synchronize transmitting stations in a common-wave network, data packets and additional packets are accommodated in a frame structure. The data rates of the data packets and additional packets are derived by division, for various predefined operating modes, from a feed data rate. The additional packets contain control data and synchronization data. This configuration of the transport data stream is suitable for the transmission of MPEG2 transport streams. An additional remote control system for the transmitting stations, and additional synchronization, can be dispensed with.

Abstract: A method is described that is used for common transmission of digital- and analog-modulated radio and/or television signals, in particular over a broad band cable system (30). The method includes transmitting at least one digital radio and/or television signal along with an analog television signal in one and the same channel, in which the frequency spectrum of the at least one digital radio and/or television signal is limited to a frequency range that is less than the width of the at least one channel. To lessen the influence of the at least one digital radio and/or television signal on the analog television signal, the at least one digital radio and/or television signal must fall below a predetermined signal level, and the peak level of the analog television signal must exceed a predetermined value, which is markedly higher than the predetermined signal level of the at least one digital radio and/or television signal.
