Abstract: A coding and modulation apparatus and method are presented. The apparatus comprises an encoder that encodes input data into cell words, and a modulator that modulates said cell words into constellation values of a non-uniform constellation. The modulator is configured to use, based on the total number M of constellation points of the constellation and the code rate, a non-uniform constellation from one or several groups of constellations each comprising one or more constellations.

Abstract: A data processing method is provided in which a transmission frame is received from a transmitting device. The transmission frame is based on a split stream for one of a plurality of channels and channel bonding signaling information. Further, the received transmission frame is processed. The channel bonding signaling information includes signature information that uniquely identifies the input stream, and the signature information is contained in a header of the transmission frame of a plurality of channels and transmits the split streams, for example.

Abstract: 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.

Abstract: A coding and modulation apparatus and method are presented. The apparatus (10) comprises an encoder (11) that encodes input data into cell words, and a modulator (12) that modulates said cell words into constellation values of a non-uniform constellation. The modulator (12) is configured to use, based on the total number M of constellation points of the constellation and the signal-to-noise ratio SNR in dB, a non-uniform constellation from a group of constellations comprising one or more of predetermined constellations defined by the constellation position vector w0 . . . b−1, wherein b=M/4.

Abstract: An apparatus and a corresponding method for mapping payload data of mapping input data streams onto a mapping output data stream having a channel bandwidth for transmission in a multi-carrier broadcast system includes first and second frame forming mechanisms. The first frame forming mechanism is adapted to form first frames having a first frame structure and the second frame forming mechanism is adapted to form second frames having a second frame structure. Preferably, in a second frame structure the data blocks of a particular mapping input data stream are spread in time and frequency over various data symbols and various data segments of the second frames to provide high robustness against disturbances. The payload portion of the second frame is preferably segmented into various data segments enabling use of a narrow-band receiver, even if both the first and second frames cover the same total channel bandwidth.

Abstract: A transmitter and a receiver for communicating data using at least two separate RF channels using channel bundling. The transmitter includes a data stream partitioner configured to partition a data stream of data to be communicated into two or more stream partitions, two or more modulators configured to each receive a stream partition and to generate modulated data from the received stream partition, and an interleaver configured to assign the modulated data generated by a modulator from a received stream partition to different RF channels for transmission.

Abstract: A transmission apparatus and method, respectively, mapping payload data of mapping input data streams onto a mapping output data stream having a channel bandwidth for transmission in a multi-carrier broadcast system. To enable selection of robustness for transmission of data, the apparatus includes a frame forming mechanism mapping data blocks of at least two mapping input data streams onto frames of the mapping output data stream covering the channel bandwidth, each frame including a payload portion, the payload portion including plural data symbols and being segmented into data segments each covering a bandwidth portion of the channel bandwidth. The frame forming mechanism is configured to map the data blocks of the at least two mapping input data streams onto data symbols of the payload portion and includes a MIMO mode selector selecting a MIMO mode of the data blocks per data segment and/or per mapping input data stream.
