摘要： An object is to provide 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. A modulation device 3 transmits an acoustic signal superposed with a PN sequence set according to a carrier frequency and a data signal. A demodulation device 9 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 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 38 decides the carrier frequency band of the data signal superposed on the acoustic signal and demodulates the data signal.

摘要： To present a plurality of functions that is a candidate for implementation based on an input character string, and to support a user in selecting a function.
Server device 10 acquires input information input into terminal device 20 (SA1 to SA3), recognizes the input information with reference to a dictionary file, the dictionary file serving as a voice-recognition dictionary describing an identifier representing a category, the category being determined based on a meaning of a registered character string, and specifies an input character string and the first identifier, the first identifier representing a category of a registered character string included in the input character string (SA5). Server device 10 transmits the specified character string and first identifier to terminal device 20 (SA6). Terminal device 20 selects, with reference a function-selection file describing a correspondence between the first identifier and a category to which a function to be presented belongs, a category to which a function corresponding to the first identifier belongs (SA7 to SA9), and presents a plurality of functions belonging to the selected category in a predetermined presenting manner (for example, prior to the other functions) (SA10).
