    摘要： In communication transmitting a first stream (intermittent data portion) for burst transmission of packet sets and a second stream (continuous data portion) for transmitting packets at a speed determined by the transmission rate required for the service, the second stream related to the selected service is received and reproduced for the selected service when a service is selected until intermittent data transmitted in the first stream can be received, and reception and playback of the first stream begins when transmission of the intermittent data for the selected service in the first stream begins.

    摘要： Although the capacity of a packet is reduced, a parity code generated by a shortened error correction code of RS (255,191) is inserted into a private data field of an adaptation field of a TS packet. In the adaptation field, as positions where the parity codes are inserted, two positions can be used. The first position is a “stuffing byte” field the length of which is indirectly known on the basis of an adaptation field length field. The second position is a “transport private data” field the length of which can be directly described by a transport private data length field.

    摘要： Disclosed is an OFDM signal receiving apparatus for diversity reception, with a plurality of antennas, of an OFDM signal containing Y sub-carriers, where 2X−1 1. The OFDM signal receiving apparatus includes a plurality of receiving systems, and a diversity processing unit connected to the receiving systems and fed with sequences of data on sub-carriers demodulated by the respective receiving systems. At least one of the receiving systems includes an FFT circuit for Fast Fourier transforming, in parallel, only a sequence of data on 2Z sub-carriers contained in the OFDM signal received with a corresponding antenna, where X>Z. The diversity processing unit performs a diversity process on sequences of data on sub-carriers, out of all the Y sub-carries, redundantly demodulated.
