Abstract
A method of estimating the interlacing mode used in a series of video frames presented as a sequence of fields is described. In one implementation, the method includes calculating a metric indicative of the difference between a current field of the sequence and a previous field of the sequence and determining from the metric so calculated the most likely type of the current field by reference to a Hidden Markov Model.
