DATA MULTIPLEX BROADCAST METHOD AND SYSTEM, RECEIVER AND SOUND RECORDER

摘要

PROBLEM TO BE SOLVED: To support a receiving side to recognize the breaks of a series of contents elements which are shown by the received data by multiplexing- broadcasting the data to be transmitted and a code that changes its state in response to the start of each of contents elements shown by the said data. SOLUTION: The DAB broadcast waves which are received by an antenna 121 and a tuner 122 are demodulated by an OFDM demodulator 123 and decoded by a channel decoder 124 in terms of their channels. Then the sound signals are extracted as the analog voice signals. A controller 127 detects the state of a user interface 128 and recognizes the operating contents of a user to control a series of these actions. Then the controller 127 receives the contents of the FIC and PAD which are decoded by a channel decoder 124 and an audio decoder 125 from each device and extracts the necessary program related information to recognize whether the broadcast contents show the music or a conversation.
