Random backoff apparatus and method for retrieval of augmenting broadcasting content

PURPOSE: A random backoff apparatus for an augmented content reception and a method thereof are provided to enable multiple viewers to efficiently use a bi-directional service by preventing multiple reception terminals from being connected to a program-related website or augmented content at the same time. CONSTITUTION: A reception terminal (510) receives meta data from a server (520). In case a first random backoff is included in the meta data, the receiving unit (511) of the reception terminal indicates a reception request of augmented content by using the first random backoff. The control unit (512) of the reception terminal requests the reception of the augmented content to the server after implementing the first random backoff. In case the first random backoff is not included in the meta data, the control unit generates the first random backoff by using a probability distribution of predetermined random sampling numbers (502) and parameters of random sampling numbers (503). [Reference numerals] (500) Random number direction; (501) Whether the random number is directed or not; (502) Random number distribution; (503) Random number parameter; (511) Receiving unit; (512) Control unit; (521) Transmitting unit; (522) Providing unit
