A remote controller, a receiving apparatus and a method of transmitting signals are provided to support multiple users in a digital television data broadcasting. A remote controller includes a button unit(301), a database(307), a key code generating unit(302), an identifier data inserting unit(303) and a plurality of transmitting units(304,305,306). The button unit inputs signals through buttons. The database contains key code data and identifier data. The key code generating unit extracts the key code data from the database, based on each of the signals input through each of the buttons. The identifier data inserting unit inserts the identifier data to the key code data to generate a key code signal. The plurality of transmitting units modulate the key code signal to a wireless signal and transmit the wireless signal. |
