Abstract:
1. A method for processing a sequence digital video fields, comprising: receiving the sequence of digital video fields; determining a current field similarity value for each current field that is being received with a second most recently received field, wherein a small value for the current field similarity value indicates that the current field is dissimilar to the second most recently received field, and a large value for the current field similarity value indicates that the current field is similar to the second most recently received field; associating the current field similarity value with the current field; determining a first sequence of five consecutive fields comprising a first field having a large current field similarity value followed by a second, third, fourth, and fifth consecutive fields each of which having a small current field similarity value; assigning an index value starting at zero, incrementing by one, and ending at four to the first sequence of five consecutive fields, wherein the first field is assigned an index value of zero, and the second, third, fourth and fifth consecutive fields are assigned the index values of one, two, three and four, respectively; processing each field having an even index value using an immediately preceding field, wherein the even index value corresponds to any one of the index values of zero, two, and four; and processing each field having an odd index value using an immediately following field, wherein the odd index value corresponds to any one of the index values of one, and three.
