The present invention relates to a method of processing information by a content receiver. According to an embodiment, the method includes detecting multi-dimensional code data split and inserted into a content provided through broadcast or an IP when the content is played, temporarily storing the detected multi-dimensional code data, synthesizing the temporarily stored multi-dimensional code data into a multi-dimensional code, when the play of the content is terminated, outputting the synthesized multi-dimensional code image on a screen or making a connection to a server corresponding to a URL obtained by decoding the synthesized multi-dimensional code image or generating and displaying a new multi-dimensional code based on the multi-dimensional code image. The identifier of the broadcast receiver or user's identifier is transmitted to the connected server so that a viewer may be compensated for watching the content.
