    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.

    Abstract: Disclosed is a media content reception method for providing augmenting media contents using graphic objects, including: receiving metadata including information representing each event of any one of broadcast contents or moving picture contents, and any one of the broadcast contents or the moving picture contents and graphic object related information associated with events, the events including at least one of a specific scene, a specific situation, and a specific phenomenon of any one of the broadcast contents or the moving picture contents; analyzing the received metadata; designating the graphic objects to correspond to each event within any one of the broadcast contents or the moving picture contents based on the analyzed metadata; and displaying the designated graphic objects to meet each event at the time of playing any one of the broadcast contents or the moving picture contents.
