Patent ID: 8537281

Claim:
A signal processing method, applied to an odd field and an even field, comprising: receiving an odd field SYNC data of the odd field and an even field SYNC data of the even field, wherein the odd field SYNC data is different at a certain data segment when compared with the even field SYNC data; adding the odd field SYNC data and the even field SYNC data to neutralize the odd and even field SYNC data so as to generate a combined odd and even field SYNC data; performing a predetermined signal processing on an input signal according to the combined odd and even field SYNC data; and wherein the step of adding the odd field SYNC data and the even field SYNC data to neutralize the odd and even field SYNC data so as to generate the combined odd and even field SYNC data comprises: performing an adding operation, an average operation, or an equalization operation on the odd field SYNC data and the even field SYNC data to generate the combined odd and even field SYNC data.
