Abstract:
1. A method of processing information by a content receiver, the method comprising: detecting multi-dimensional code data from a content provided through broadcast or an IP when the content is reproduced, the multi-dimensional code data being inserted into the content in a split manner; temporarily storing the detected multi-dimensional code data; and synthesizing the temporarily stored multi-dimensional code data into a multi-dimensional code, wherein the multi-dimensional code data includes splitting information for the multi-dimensional code and data for pieces included in an array of pieces and generated when the multi-dimensional code is split, wherein the splitting information includes size information of the multi-dimensional code and information on the number of the split pieces which are required for synthesizing an image of the multi-dimensional code from the data for the pieces, wherein the data for the pieces includes positional information indicating where a corresponding piece is placed in the multi-dimensional code and a bit stream for bitmap data of the corresponding piece, and wherein each piece takes up a plurality of cells less than cells of the multi-dimensional code, and each cell among the plurality of cells in each corresponding piece is included in an array of cells and represents one bit.
