The invention relates to a method and apparatuses for improved transmission of broadcasts, which make it possible to ensure considerably more efficient utilization of available transmission channels, while at the same time allowing individual subscribers to make a more individual selection of a specific broadcast programme. To do this, the invention provides that at least one first and one second signal sequence (5, 6, 7, 8, 9) having defined signal characteristics can be produced and can be transmitted, in which case a large number of information blocks are embedded in the first signal sequence (5), and control information referring to individual information blocks is embedded in the second signal sequence (6, 7, 8, 9) in such a way that a receiver device (2) which is matched to the signal characteristics accesses the information block associated with the control information in response to control information being received in a selected second signal sequence (6, 7, 8, 9). An apparatus is provided for the reception of such broadcasts, having devices (2), which separates a first and a second signal sequence (5, 6, 7, 8, 9) from a number of first and second signal sequences having defined signal characteristics, and accesses an information block associated with specific control information, from the first signal sequence (5), in response to such control information contained in the second signal sequence (6, 7, 8, 9).
