ABSTRACT:
Methods and systems for determining fields in a video signal are disclosed. Historic field ID values for a received video signal may be stored and subsequently utilized by a summer and/or a correlator in order to estimate a field ID value for a current field. The summer may sum all historic field ID values and, if the sum is within a determined range, for example, the field ID value for a current field may be estimated based on the sum of the historic field ID values. If the sum is not within the determined range, for example, the historic field ID values may be correlated with an expected field ID value or with an inverted expected field ID value. The correlation may then be utilized to estimate the field ID value for the current field.
