    摘要: Provided is a broadcast supplemental data transmission device, a broadcast supplemental data transmission method, and a broadcast system that can reduce the traffic of a communication network as much as possible at the time of supplementing missing data in broadcasted content data. When “GET HTTP/1.1 If Unmodified Since Time Information”, which is a request for retransmission of missing data containing time information, is received from a receiving device, an HTTP response module determines whether there is rebroadcast of contents containing missing data based on the time information contained in the request for retransmission. When it is determined by the HTTP response module that there is rebroadcast, “412 Precondition Failed”, which is one of error notifications, is transmitted as a response to the receiving device, and the transmission of the contents through a communication network is not performed.

    摘要: A modulation device, a demodulation device, and a transmission system and acoustic signal transmission method using them which can carry out a synchronization process for data signals without using a carrier frequency for a synchronization signal. The modulation device transmits an acoustic signal superposed with a PN sequence set according to a carrier frequency and a data signal. A demodulation device receives the acoustic signal, determines the PN sequence having the highest maximum correlation value with the acoustic signal in a plurality of PN sequences, detects a symbol synchronization point according to the correlation value between the thus determined PN sequence and the acoustic signal, and performs a synchronization process. Thereafter, according to the detected synchronization point and determined PN sequence, an OFDM demodulation processing unit decides the carrier frequency band of the data signal superposed on the acoustic signal and demodulates the data signal.
