Abstract: Provided is a random backoff apparatus and method for receiving augmented content that may prevent a delay or a down of a server caused by a plurality of receiving terminals accessing a server simultaneously, when a digital broadcasting system provides broadcast-based bidirectional broadcasting services over a communication network. That is, a technology for distributing receiving terminals accessing a server to receive augmented content, or accessing a home page of a corresponding program, based on metadata transferred from the digital broadcasting system to a broadcasting network. In a bidirectional digital method, a number of requests for access to the home page or the augmented content related to the program may be received from receiving terminals at one time. Accordingly, there is a desire for a method of preventing collision caused when a plurality of stations simultaneously access a single wireless channel.
