A method of detecting a change in a broadcasting table indicating broadcasting information from cyclic redundancy check (CRC) data of section information of a broadcasting stream. The method includes: storing section information of a broadcasting stream including a version number, a section number, table information, and cyclic redundancy check data; comparing cyclic redundancy check data of first input table information in the section number of the broadcasting stream with cyclic redundancy check data of subsequent input table information in the section number of the broadcasting stream; and parsing and updating the table information if the cyclic redundancy check data is changed.
