ABSTRACT:
Certain aspects of a method and system for inverse telecine and field pairing may comprise receiving a plurality of fields of alternating polarity. A current field may be weaved with its corresponding adjacent field of opposite polarity. A polarity change count value may be calculated based on the weaving of the current field with its corresponding adjacent field of opposite polarity. The method may determine whether to utilize a progressive scheme or an interlaced scheme to encode the received plurality of fields of alternating polarity based at least in part on the calculated polarity change count value. At least one of a top field first (TFF) scheme, a bottom field first (BFF) scheme, a top field first-repeat first field (TFF-RFF) scheme and a bottom field first-repeat first field (BFF-RFF) scheme may be chosen to pair the plurality of fields of alternating polarity.
