Receiver for receiving data frames which contain information data and signaling data, the signaling data comprising a data frame identifier and a decoding instruction for decoding the information data, having: (a) a signal input (2) for receiving data frames which are transmitted on a transmission channel, (b) a data frame separator circuit (11) for separating the signaling data from the information data, and (c) a controllable switching device (20) which, as a function of a control signal, connects through the signaling data present at a first data input (22) of the switching device (20) or the information data present at a second data input (19) of the switching device (20) to a data output (30) of the switching device (20); (d) a channel decoding circuit (35), connected to the data output (32) of the switching device (20), for decoding the data which is present, the channel decoding circuit generating indicator signals which indicate whether the decoding of the data which is present has been carried out without error by the channel decoding circuit (35); and having (e) a control circuit (27, 38; 52), in which case, when a first indicator signal which indicates the error-free decoding of the signaling data of a data frame is received, the control circuit (27, 38; 52) buffers the information data, the decoding instruction for decoding the information data and the data frame identifier in a memory (16; 56) and outputs a control signal to the switching device (20) in order to connect through the buffered information data to the channel decoding circuit (35), in which case, when a second indicator signal which indicates the error-free decoding of the information data by the channel decoding circuit (35) is received, the control circuit (27, 38; 52) outputs the decoded information data to a downstream data processing unit for further data processing.
