Title:
BROADCAST SYSTEM, TRANSMITTER AND RECEIVER FOR USE IN SAME, BROADCAST METHOD AND BROADCAST PROGRAM, RECEPTION PLAYBACK METHOD AND RECEPTION PLAYBACK PROGRAM, AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2013/084430
Kind Code:
A1
Abstract:
In a broadcast system (100) of the ISDB-T transmission standard, a transmitter (200) is provided with: a TS remultiplexer (231) for multiplexing a TS; a hierarchical parallel processor (232) for performing processes including byte interleaving and convolutional coding on the multiplexed TS, and generating an OFDM transmission signal; and a transmitting part (203) for transmitting the OFDM transmission signal, while a receiver (300) is provided with a receiving part (301) for receiving an OFDM transmission signal, and a decoder (302) for Viterbi decoding of the received OFDM transmission signal. The TS remultiplexer (231) arranges the core packets and delay packets alternately in identical repeating units, and in such a way that the positional relationship each core packet and the delay packet corresponding thereto is a fixed relationship. During Viterbi decoding, the decoder (302), having determined the data of the delay packet corresponding to a core packet from the data of the core packet in question decoded previously, ascertains the route of the data of the core packet adjacent to the determined data of the delay packet.
