<p><P>PROBLEM TO BE SOLVED: To provide a reception apparatus for reliably obtaining re-synchronism. <P>SOLUTION: The reception apparatus includes: a time lag detection section 51 configured to count a relative time by an ISCR counter 51A, which is obtained by successively adding packet rates P<SB>ts</SB>with respect to a reference time indicated by an ISCR to be reference among the ISCRs added to TS packets concerning the TS packets of Common PLP and Data PLP to be read from a buffer 31, compare the counted relative time with an additional time indicated by the ISCR temporally after the ISCR to be reference, and detect the time lag; and a time lag correction section 52 configured to correct a displacement in the time direction between the Common PLP and Data PLP stored in the buffer 31, based on the detection result by the time lag detection section 51. Thus, the re-synchronism is reliably obtained even in out-of-synchronism between the Common PLP and Data PLP. The invention is applied to the reception apparatus for receiving a signal by an M-PLP system in DVB-T.2. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
