A receiver is arranged for receiving a signal comprising an interleaved symbol stream. The receiver comprises a convolutional deinterleaver comprising a plurality of delay portions each of which is arranged to delay symbols from the symbol stream from an input to an output by a different amount, the delay portions being arranged in a sequence. An input selector is configured to input the symbols from the symbol stream to the delay portions so that successive symbols are input in accordance with the sequence of the delay portions. An output selector configured to read the symbols from the delay portions by successively selecting the symbols from the outputs of the delay portions in accordance with the sequence of the delay portions to form a deinterleaved symbol stream.

Receiver receiving a signal including physical layer frames, and including a convolutional deinterleaver and a deinterleaver selector

A transmitter for transmitting payload data and emergency information using data symbols in a single-carrier or multi-carrier broadcast system comprises a modulator configured to modulate one or more transmission symbols with signaling data for use in detecting and recovering the payload data at a receiver and to modulate one or more transmission symbols with the payload data. An emergency information receiver receives emergency information carrying information of an actual emergency. An emergency information embedder embeds emergency information into one or more transmission symbols, wherein the emergency information is embedded within a predetermined time period after its reception by using a resource used for carrying signaling data and/or payload data if no emergency information shall be transmitted. A transmission unit transmits the transmission symbols.

Transmitter and transmission method for transmitting payload data and emergency information

A data processing apparatus maps input symbols to be communicated onto a predetermined number of sub-carrier signals of an Orthogonal Frequency Division Multiplexed (OFDM) symbol. The data processor includes an interleaver memory which reads-in the predetermined number of data symbols for mapping onto the OFDM sub-carrier signals. The interleaver memory reads-out the data symbols on to the OFDM sub-carriers to effect the mapping, the read-out being in a different order than the read-in, the order being determined from a set of addresses, with the effect that the data symbols are interleaved on to the sub-carrier signals. The set of addresses are generated from an address generator which comprises a linear feedback shift register and a permutation circuit.

A data processing apparatus is arranged to map input data symbols to be communicated onto a predetermined number of sub-carrier signals of Orthogonal Frequency Division Multiplexed OFDM symbols. The predetermined number of sub-carrier signals is determined in accordance with one of a plurality of operating modes and the input data symbols are divided into first sets of input data symbols and second sets of input data symbols.
