Abstract:
1. A television (TV) receiver to synchronize a demodulator in said TV receiver by performing a method of bit de-interleaving even Orthogonal Frequency Division Multiplexing (OFDM) symbols, and odd OFDM symbols from a plurality of OFDM symbols using one or more channel modulation parameters, and effectively reducing channel change times in said TV receiver, said method comprising: (i) detecting said even OFDM symbols and said odd OFDM symbols from said plurality of OFDM symbols; (ii) de-interleaving said even OFDM symbols and said odd OFDM symbols based on a positions of scattered pilots when a frame boundary does not exist for said plurality of OFDM symbols; and (iii) bit de-interleaving said even OFDM symbols and said odd OFDM symbols, wherein said channel change times is reduced by 1/n times of a super frame boundary for an OFDM symbol boundary, wherein n is number of OFDM symbols in said super frame boundary, wherein said channel change times is reduced by 1/p times of said super frame boundary for said frame boundary, wherein p is number of frames in said super frame boundary.
