摘要： A transmission apparatus and transmitting method for signaling parameters of a preamble, and a reception apparatus and receiving method for decoding the preamble. The transmitting method includes generating, using processing circuitry of a transmission apparatus, a bootstrap symbol based on the parameters of the preamble. The bootstrap symbol is prefixed to a frame that includes the preamble using the circuitry. The bootstrap symbol is selected from a plurality of patterns. Further, the plurality of patterns represent at least a subset of predetermined combinations of the parameters of the preamble including an FFT (Fast Fourier Transform) size, a guard interval, a frequency domain displacement component of a SPP (Scattered Pilot Pattern) and a L1 mode.

摘要： A method for signaling preamble structure parameters is provided. A bootstrap symbol is generated that indicates a preamble structure value. The preamble structure value indicates one of a plurality of different combinations of the preamble structure parameters of a preamble that follows the bootstrap symbol. The preamble includes a first part and a second part. A transmission frame that includes the bootstrap symbol, the preamble, and a data payload is generated. The transmission frame is output for transmission. Further, one of the preamble structure parameters is a forward error correction mode for the first part of the preamble.

摘要： A method for signaling preamble structure parameters. The method includes generating a bootstrap symbol that signals a single 8-bit preamble structure value. The single 8-bit preamble structure value identifies four different preamble structure parameters of a preamble that follows the bootstrap symbol. The method further includes generating a transmission frame including the bootstrap symbol, the preamble, and a data payload, and outputting the transmission frame for transmission via a terrestrial broadcast. The single 8-bit preamble structure value is limited to signaling a subset of different combinations of the four different preamble structure parameters.

摘要： A FIFO memory which reads data in response to a read request from a plurality of read units is realized with a simple configuration.When there is a data writing request to a first-in first-out data bolding unit provided with a plurality of entries in each of which data is held, a write pointer control unit writes data in the entry indicated by a write pointer out of a plurality of entries and updates the write pointer. Also, a read pointer control unit reads the data from the entry indicated by a read pointer corresponding to a read unit which requests data reading out of a plurality of read pointers associated with different read units and updates a corresponding read pointer.

摘要： An arrangement for detecting signaling data from bootstrap Orthogonal Frequency Division Multiplexed (OFDM) symbols in the frequency domain, which can provide a more accurate estimate of the signaling data than other arrangements that operate in the time domain. The arrangement includes detecting a cyclic shift of a signature sequence, which has been applied to represent the signaling data, as an average phase change between each of the sub-carriers of the bootstrap OFDM symbol. As a result the signaling data can be more accurately detected or detected at lower signal to noise ratio.
