<P>PROBLEM TO BE SOLVED: To provide a method and apparatus for filtering section data. <P>SOLUTION: The filtering apparatus includes: a mask generation unit 360 which generates a mask to be used for filtering section data based on a section number in a digital broadcasting receiver and the mask generation unit 360 determines whether to generate the mask based on an accumulated number of bit number 0 or 1 at each bit position of a section number already stored in the receiver. According to the method and apparatus, a section number of section data received and stored by a receiver is not directly compared to a next received section number, and by using a mask generated based on the accumulated number of the received bit numbers, filtering is performed such that the time for performing filtering is reduced. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
