DATA TRANSMITTING SYSTEM AND METHOD USING TXID

摘要

PURPOSE: A system for transmitting additional data using identification information of a transmitting device and a method thereof are provided to two-dimensionally modulate the additional data, thereby increasing a transmitting rate. CONSTITUTION: A transmitting device identification information generating unit(250) generates transmitting device identification information. A modulation unit(260) modulates performs modulation by performing circular shift in the transmitting device identification information according to a value of additional data. A transmitting unit(240) transmits the modulated transmitting device identification information.
