    摘要: A control device for use in a broadcast system includes a broadcast controller that controls a broadcast transmitter of the broadcast system that broadcasts broadcast signals in a coverage area for reception by terminals including a broadcast receiver and a broadband receiver, and a broadband controller that controls a broadband server of a broadband system that provides redundancy data to terminals within the coverage area. The broadband controller is configured to control the provision of redundancy data by the broadband server for use by one or more terminals which use the redundancy data together with broadcast signals received via said broadcast system for recovering content received within the broadcast signals and/or provided via the broadband system.

    摘要: A receiver for receiving data in a broadcast system includes a broadcast receiver configured to receive, via the broadcast system, a receiver input data stream including a plurality of channel symbols represented by constellation points in a constellation diagram. A demodulator demodulates the channel symbols into codewords and a decoder decodes the codewords into output data words. A redundancy unit selects or requests, if demodulation of a channel symbol and/or decoding of a codeword is erroneous or likely to fail, redundancy data for demodulation of future channel symbols and/or decoding of future codewords via a broadband system and a broadband receiver obtains the redundancy data via the broadband system. The demodulator and/or the decoder is configured to use the obtained redundancy data to demodulate the respective future channel symbols and to decode the respective future codewords, respectively.

    摘要: The present technology relates to a data processing device and a data processing method capable of performing appropriate stream processing.An input stream is split into a split stream for each of a plurality of channels. A stream to be generated includes the split stream, and signature information unique for each of the input streams containing the split stream, or includes the split stream, the signature information, and location information about a transmission frequency band of a split stream constituting the input stream and different from the split stream included in the generated stream. The present technology is applicable to a channel bonding (CB) technology which splits an input stream into streams of a plurality of channels and transmits the split streams, for example.

    摘要: The present invention relates to a transmission apparatus and a corresponding transmission method for transmitting data within a multi-carrier transmission system comprising two or more transmission apparatuses that are configured to transmit the same data. To avoid destructive interferences a transmission apparatus (10) is proposed comprising a signal input (30) configured to receive multi-carrier signals (S(k)) carrying data to be transmitted, a distortion unit (32) configured to distort said multi-carrier signals (S(k)) by use of a distortion function (P(k)) including a phase parameter for differently modulating the phase of said multi-carrier signals (S(k)), wherein said distortion function (P(k)) is different from distortion functions used by other transmission apparatuses, whose coverage areas overlap with the coverage area of the present transmission apparatus, by using a phase parameter that is different from the phase parameter used by said other transmission apparatuses, and a transmission unit (34) configured to transmit said distorted multi-carrier signals as transmission signal (Tx(k)).

    摘要: 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, the signal-to-noise ratio SNR in dB and the channel characteristics, a non-uniform constellation from a group of constellations comprising one or more of predetermined constellations defined by the constellation position vector u1 . . . v, wherein v=sqrt(M)/2−1.

    摘要: A reception apparatus including a tuner and circuitry is provided. The tuner is configured to receive a transmission frame. The circuitry is configured to detect a last symbol of a first part of the transmission frame. The circuitry is configured to extract first signaling information, from the last symbol of the first part of the transmission frame, to decode a second part of the transmission frame. The circuitry is configured to remove a guard interval of a symbol of the second part of the transmission frame based on the guard interval indicated by the first signaling information. The circuitry is further configured to recover payload data from a third part of the transmission frame based on second signaling information included in the second part of the transmission frame. The first part is a bootstrap portion, the second part is a preamble portion, and the third part is a payload portion.
