摘要：
A terrestrial transmitting station for sending out a terrestrial broadcast signal includes a first receiver for receiving a signal to obtain a satellite receive signal, a second receiver for receiving a local signal to obtain a local receive signal and a signal combiner for combining the first receive signal with the local receive signal to form a combination signal. The signal combiner is implemented to generate the combination signal so that the combination signal is formed according to a hierarchical modulation, wherein the first receive signal is contained in a base layer of the hierarchical modulation and wherein the local receive signal is contained in an overlay layer of the hierarchical modulation. A terrestrial transmitting station further includes a transmitter for sending out the combination signal. A broadcast system includes a first transmitter and at least one terrestrial transmitting station. The information emitted from the satellite-based broadcast system may be received using an associated receiver. An inventive broadcast system allows adding a local information to a supraregionally emitted transmit signal in a frequency-efficient way.
